Paediatric Neurodisability: Facilitation, Assessment & Physiotherapy Management

---

3. Facilitation of Development in Neurologically Disabled Children

Principles of Developmental Facilitation

• Experience-dependent neuroplasticity: Repeated, task-specific, active movement creates lasting cortical reorganisation. This underpins all modern facilitation approaches.
• Normal movement as the goal: The aim is to guide the child toward movement patterns that are as biomechanically efficient as possible, preventing compensatory patterns that lead to secondary musculoskeletal deformity.
• Child-led participation: Therapy should be embedded in meaningful, motivating activities - the child must be an active participant, not a passive recipient.
• Family-centred care: Parents and caregivers are trained as co-therapists, ensuring carry-over of facilitation strategies into daily routines at home.
• Multidisciplinary team (MDT): Physiotherapy, occupational therapy (OT), speech-language therapy, psychology, and education services must be coordinated for holistic development.

Key Facilitation Techniques

• Head control: Prone positioning, vestibular stimulation, supported sitting in midline
• Rolling: Facilitating segmental rotation through pelvis and shoulder girdle
• Sitting: Using bolsters, therapy balls; facilitating equilibrium reactions in all planes
• Standing/gait: Parallel bars, gait trainers, treadmill training with partial body weight support (PBWS)

3. Congenital and Acquired Disorders Affecting Growth and Development

A. Congenital Disorders

• Causes: Periventricular leukomalacia (premature infants), hypoxic-ischaemic encephalopathy (term infants), cortical malformations, genetic/chromosomal causes (10-14% of CP cases have a monogenic or chromosomal variant - Bradley & Daroff's Neurology)
• Classification: Spastic (most common, ~80%), dyskinetic/athetoid, ataxic, mixed
• Topographic: Hemiplegia, diplegia, quadriplegia
• Impact on development: Abnormal tone, primitive reflex persistence, delayed motor milestones, musculoskeletal deformities (hip displacement, scoliosis, equinus foot), associated impairments (epilepsy in ~35%, cognitive impairment, visual/hearing deficits, feeding difficulties)

• Neural tube defect; ranges from spina bifida occulta (no neurological involvement) to myelomeningocele (herniation of spinal cord and meninges through vertebral defect)
• Leads to: lower limb paralysis/weakness, sensory loss, neurogenic bladder and bowel, hydrocephalus (requiring VP shunt), associated Arnold-Chiari II malformation
• Physiotherapy targets: prevention of contractures, strengthening of innervated muscles, mobility aids, skin care education

• Hypotonia (central and peripheral), ligamentous laxity, atlantoaxial instability
• Delayed motor milestones, intellectual disability, congenital heart defects
• Physiotherapy: tone management, strength training, gross motor facilitation, sport participation

• X-linked; dystrophin deficiency causing progressive proximal muscle weakness
• Gowers' sign, calf pseudohypertrophy, cardiomyopathy, respiratory compromise
• Physiotherapy: maintain ambulation, prevent contractures (serial casting, night splints), respiratory physiotherapy, transition to powered wheelchair

B. Acquired Disorders

• Leading cause of acquired disability in childhood
• Mechanisms: road traffic accidents, falls, non-accidental injury (shaken baby syndrome)
• Outcomes depend on GCS at presentation, depth and duration of coma, extent of diffuse axonal injury (DAI)
• Rehabilitation: cognitive retraining, spasticity management, gait rehabilitation, return-to-school planning

• Bacterial meningitis: may cause sensorineural hearing loss, hydrocephalus, cortical necrosis
• Viral encephalitis (HSV, Japanese encephalitis): seizures, movement disorders, intellectual regression
• Physiotherapy: tone normalisation, communication aids, sensory stimulation programmes

• Perinatal asphyxia causing brain injury; managed with therapeutic hypothermia in neonates
• Outcomes range from full recovery to severe CP or death depending on severity

• Acquired quadriplegia/paraplegia; complete vs. incomplete injury (ASIA scale)
• Physiotherapy: respiratory management, pressure care, passive ROM, functional electrical stimulation (FES), locomotor training

• Posterior fossa tumours (medulloblastoma, astrocytoma): post-surgical cerebellar ataxia, truncal instability, cerebellar mutism
• Cortical tumours: hemiplegia, seizures, cognitive effects
• CNS radiotherapy: white matter changes, intellectual decline over years

4. Advanced Skills in Assessment of Paediatric Neuropathological, Neuropsychological & Neurosurgical Conditions

A. Neuropathological Assessment

• MRI brain: Pattern recognition - periventricular leukomalacia (PVL) in premature CP, basal ganglia lesions in dyskinetic CP, cortical malformations, posterior fossa hypoplasia
• MRI spine: Level of cord injury or tethered cord in spina bifida
• Head ultrasound: Neonatal intraventricular haemorrhage grading (Papile Grades I-IV)

• Tone assessment: modified Ashworth scale (MAS), modified Tardieu scale (MTS - gold standard for distinguishing spasticity from contracture)
• Reflexes: persistence of primitive reflexes (Moro, ATNR, grasp beyond expected age = pathological)
• Cranial nerve examination: ocular alignment, bulbar function, facial symmetry
• Gait analysis: clinical and instrumented (3D computerised gait analysis - kinematics, kinetics, EMG)

B. Neuropsychological Assessment

• Intelligence (WISC-V, Bayley Scales of Infant and Toddler Development - BSID-IV)
• Attention and executive function (BRIEF, CONNERS scales, NEPSY-II)
• Memory (verbal and visual - WRAML, CMS)
• Language (CELF-5, ROWPVT)
• Visuospatial and visuomotor skills (Beery VMI, RCFT)
• Adaptive behaviour (Vineland Adaptive Behavior Scales - VABS-3)
• Emotional/behavioural functioning (CBCL, SDQ)

• Epilepsy: Pre-surgical neuropsychological evaluation to lateralise/localise language and memory, assess cognitive risk of surgery. Wada test or fMRI language mapping used in older children.
• Brain tumour survivors: Longitudinal monitoring for late effects of surgery, chemotherapy, radiation on cognition, attention, and processing speed
• Premature infants: Neurodevelopmental follow-up at 2 years corrected age and school entry using Bayley, Movement ABC, and school-specific cognitive tools

C. Neurosurgical Assessment Collaboration

• Baseline functional assessment: GMFCS level, manual ability classification (MACS), GMFM-66 scores
• Goal setting for selective dorsal rhizotomy (SDR) candidacy:
  • Ideal SDR candidate: spastic diplegia, GMFCS II-III, preserved strength, no dystonia, strong family support and therapy access
• Assessment for intrathecal baclofen pump: widespread spasticity not responding to oral medications, adequate trunk control for pump implant (Bradley & Daroff's, p. 2403)

• After SDR: intensive physiotherapy for 6-12 months to capitalise on tone reduction; strengthening, gait retraining
• After VP shunt: monitor for shunt malfunction signs; maintain positioning, avoid rapid head movements
• After spinal surgery (scoliosis correction in CP/NMD): respiratory physiotherapy, early mobilisation, pain management

5. Advanced Physiotherapy Approaches - Neurophysiological Principles & Handling Skills

A. Neurodevelopmental Treatment / Bobath Concept (NDT)

• Originally based on hierarchical reflex model; modern Bobath integrates systems theory, motor learning, neuroplasticity, and International Classification of Functioning, Disability and Health (ICF) framework
• Key premise: abnormal tone and movement patterns can be modified through skilled handling, allowing the CNS to experience and learn more efficient movement

• Key points of control (KPoC): Proximal (pelvis, shoulder girdle, head) and distal points used to influence tone throughout the body
• Facilitation: Manual guidance through movement to prompt active participation
• Inhibition (reflex inhibiting postures/patterns): Positions and movement that reduce abnormal reflex activity and spasticity
• Preparatory handling: Normalise tone and alignment before functional task practice
• Task practice: Embed handling within meaningful functional contexts (play, dressing, eating)

B. Proprioceptive Neuromuscular Facilitation (PNF)

• Rhythmic initiation: Passive → active-assisted → active movement to overcome hypertonia and initiate movement
• Repeated contractions: Repeated stretch reflex in weak muscles to recruit motor units
• Hold-relax / contract-relax: Autogenic inhibition via Golgi tendon organ; used to increase range of motion
• Slow reversal: Alternating agonist-antagonist contraction to develop co-contraction and dynamic stability
• Patterns: UE D1 (flexion: shoulder flexion, adduction, external rotation) and D2; LE D1 and D2 patterns
• Application in children: Modified for developmental stage; PNF principles used in mat activities, gait training, and balance work

C. Vojta Therapy (Reflex Locomotion)

• Used from early infancy; activates postural control, righting reactions, and coordinated limb movement
• Recent systematic evidence (Sanchez-Gonzalez et al., 2024) confirms neurophysiological robustness of Vojta's reflex locomotion mechanisms
• In a 2025 study on congenital muscular torticollis (n=53), Vojta showed greater angular improvements vs NDT Bobath

D. Sensory Integration Therapy (Ayres)

• Addresses underlying deficits in processing vestibular, proprioceptive, and tactile information
• Uses suspended equipment, textured surfaces, deep pressure, and resistive activities in a "just-right challenge"
• Relevant in children with sensory processing disorder, ASD, learning disabilities, and developmental coordination disorder (DCD)

E. Task-Oriented / Motor Learning Approach

• Specificity of training: practice the exact functional task you want to improve
• Part-practice vs. whole-task practice; blocked vs. random practice schedules
• Augmented feedback (knowledge of results, knowledge of performance)
• Mental practice and observation learning (mirror neuron activation)

• Circuit training for CP (Blundell et al.): 10-station circuit of functional tasks improved gross motor function
• Intensive goal-directed CIMT for hemiplegic CP: 30-60 hrs over 2 weeks significantly improves upper limb function
• Treadmill training with body weight support: improves walking speed and endurance in diplegia

F. Augmentative Technologies

• Functional Electrical Stimulation (FES): Peroneal nerve stimulator for foot drop; NMES for upper limb in hemiplegia
• Robotic-assisted gait training (RAGT): Lokomat, PABLO systems; provides consistent gait kinematics with high repetition for motor relearning
• Virtual reality (VR): Provides engaging environment for repetitive task practice with real-time feedback

---

6. Clinical Decision Making and Evidence-Based Practice

ICF Framework for Assessment and Goal Setting

Clinical Reasoning Model

• Gather data (history, examination, outcome measures)
• Generate hypotheses about impairments driving functional limitation
• Select and test interventions targeting these hypotheses
• Reassess and revise

• Level 1 (RCT/Systematic review): CIMT for hemiplegia, BoNT-A for focal spasticity, treadmill training for diplegia
• Level 2 (Cohort studies): SDR outcomes, RAGT for CP
• Level 3-4 (Case series/expert opinion): Most specific handling techniques; individual facilitation approaches

• What is the primary impairment driving the functional limitation? (Spasticity? Weakness? Sensory deficit? Selective motor control loss?)
• Is the child's GMFCS level stable or deteriorating? (Deterioration may signal missed diagnosis, need for orthopaedic review, or inadequate therapy dose)
• What does the family/child prioritise? (Goal-setting using COPM - Canadian Occupational Performance Measure)
• Is tone management needed before therapy? Or can task-specific training proceed immediately?
• Are compensatory strategies acceptable or will they cause secondary harm? (e.g., accepting toe-walking vs. managing equinus to prevent contracture)

Recent Evidence Summary (2023-2025)

Outcome Measures at a Glance

• Gross motor: GMFM-66, GMFCS, 6-Minute Walk Test, 10-Metre Walk Test
• Upper limb: MACS, QUEST, AHA (Assisting Hand Assessment), Melbourne Assessment
• Spasticity: Modified Ashworth Scale (MAS), Modified Tardieu Scale (MTS)
• Functional independence: PEDI-CAT, WeeFIM, Barthel Index (adapted)
• Quality of life: CPCHILD, Kidscreen, PedsQL
• Goal measurement: GAS (Goal Attainment Scaling), COPM

---

1. Developmental facilitation in neurologically disabled children works through neuroplasticity; timing, intensity, family involvement, and meaningful task practice are the critical variables.
2. Cerebral palsy is the paradigm condition for paediatric neurorehabilitation, but congenital (spina bifida, DMD, Down syndrome) and acquired (TBI, meningitis, SCI) conditions each require condition-specific physiotherapy pathways.
3. Advanced assessment integrates neuropathological (tone, reflexes, imaging), neuropsychological (cognition, behaviour), and functional (activity, participation) domains using validated tools.
4. No single physiotherapy approach (Bobath, PNF, Vojta, sensory integration) has proven superiority - current evidence supports high-intensity, task-specific, goal-directed therapy embedded within an NDT/motor learning framework tailored to the individual child.
5. Clinical decision making should be structured using the ICF framework, driven by the child's and family's goals, and continuously updated through objective outcome measurement and current evidence from systematic reviews and RCTs.

QUESTION 3 (PART A): FACILITATION OF DEVELOPMENT USING APPROPRIATE SKILLS IN A NEUROLOGICALLY DISABLED CHILD

---

INTRODUCTION

---

1. NEUROPHYSIOLOGICAL BASIS OF DEVELOPMENTAL FACILITATION

1.1 Neuroplasticity

1.2 Normal Motor Development as the Reference Framework

---

2. DEVELOPMENTAL FACILITATION: DOMAIN-BY-DOMAIN APPROACH

2.1 Head Control and Trunk Control (0-6 Months)

• Prone positioning on wedge: With child's elbows forward, the physiotherapist applies gentle resistance to head movement to activate neck extensors. Gradually reduce support.
• Supported sitting in midline: Use rolled towels or therapy roll to support symmetry. Therapist facilitates weight shift to activate lateral righting reactions.
• Vestibular stimulation: Tilting the child on a therapy ball in all directions activates righting reactions from the labyrinthine righting reflex.
• Prone on ball: Rolling the child forward slowly over a therapy ball triggers head righting. This is one of the earliest facilitation techniques in NDT.
• Tummy time programme: Parents coached to provide prone positioning during waking hours - minimum 20-30 minutes per day in periods.
• Key points of control (KPoC): Therapist places hands at the shoulder girdle and slowly shifts weight side-to-side. The head righting reaction should emerge in response. As the child improves, the KPoC moves distally to the pelvis.

2.2 Rolling and Transitional Movements (4-9 Months)

• Segmental rolling facilitation (NDT): Therapist places hands at pelvis and shoulder girdle. The lower half of the body is rotated first, allowing the trunk to follow in a segmental pattern, activating the oblique abdominals and spinal rotators.
• Righting reaction facilitation: From sidelying, the head is gently lifted - the trunk and legs should right themselves below. If absent, the therapist guides this sequence.
• Bridging activities: Lying supine with hips and knees flexed, the therapist facilitates a pelvic tilt and bridges. This activates gluteus maximus and hamstrings in a functional pattern.

2.3 Sitting Development (6-12 Months)

• Straddle sitting on therapist's knee: Provides excellent hip abduction and anterior pelvic tilt. Therapist stabilises pelvis and slowly introduces small weight shifts to each side, encouraging the equilibrium reactions.
• Therapy ball sitting: Child sits astride a therapy ball. The therapist holds at the hips. Slow, graded displacement challenges equilibrium reactions in sagittal, frontal, and transverse planes.
• Floor sitting with appropriate supports: Long sitting, ring sitting, tailor sitting - each challenges different aspects of trunk control. AFOs may be needed to prevent equinus interfering with sitting.
• Reaching activities: Once sitting is established, introducing reaching in all directions challenges equilibrium responses and develops selective arm control.

2.4 Standing and Walking (9-18 Months)

• Standing in standing frame: Provides weight-bearing, hip joint development (acetabular coverage), reduces risk of hip dislocation, improves bone density.
• Facilitated weight shifting: Therapist at KPoC at pelvis shifts weight side to side while child is in standing. Activates hip abductors, lateral trunk stabilisers.
• Partial body weight-supported treadmill training (PBWSTT): Child suspended in harness over a treadmill at 0-40% body weight unloaded. The treadmill provides rhythmic somatosensory input to spinal CPGs (central pattern generators). Repetition at high dose facilitates motor relearning for gait. Network meta-analysis (Qian et al., Front Neurol, 2022 [PMID 36703638]) found treadmill training among the most effective gait interventions in CP.
• Ankle-foot orthoses (AFOs): Solid AFOs for equinus - "positioning joints in the proper plane and reducing pathologic reflex or spasticity... often improve gait parameters and decrease energy expenditure in children with cerebral palsy" (Campbell's Operative Orthopaedics, p. 1579).
• Gait trainers/Lokomat: Robotic gait training shown in meta-analysis (Chen et al., Gait Posture, 2026 [PMID 41252866]) to improve lower limb motor recovery, especially when combined with conventional therapy.

---

3. HANDLING SKILLS IN DEVELOPMENTAL FACILITATION

3.1 Principles of Therapeutic Handling (NDT/Bobath Framework)

• Proximal KPoC: Pelvis, shoulder girdle, head - influence tone and movement throughout the body
• Distal KPoC: Hands, feet - for fine-tuning of distal movement
• Principle: start proximal and move distally as the child gains control - "proximal to distal key points. This is a way to withdraw your feedback or control over the movements in a gradual way ... giving more control back to patient, which is the ultimate aim" (NDT Clinicians View)

• Maximum assistance: fully guided movement (passive)
• Active-assisted: therapist supports 50-70%
• Minimal assistance: therapist provides tactile cue only
• Independent: no therapist assistance - the ultimate goal

• Slow rhythmic movement to reduce gamma motor neuron firing
• Rotational movements to reduce stiffness
• Weight-bearing through affected limbs to activate co-contraction and postural tone

---

4. SENSORY SYSTEMS IN DEVELOPMENTAL FACILITATION

4.1 Proprioceptive Input

• Joint compression: approximation through the joint stack increases co-contraction and postural tone
• Joint traction: separation of joint surfaces stimulates Type Ia, II afferents, promoting limb extension
• Resistance: activates gamma motor neurons, recruits more motor units via irradiation; a key PNF principle

4.2 Tactile Input

• Brushing (Rood): fast brushing with a soft brush activates A-beta mechanoreceptors, facilitating the muscle underneath
• Tapping: quick tapping over the muscle belly facilitates contraction via the stretch reflex
• Deep pressure: inhibitory - slow, sustained deep pressure to the muscle belly reduces muscle tone by activating Golgi tendon organs and Pacinian corpuscles

4.3 Vestibular Input

• Linear acceleration (rocking forward-backward): activates utricle and saccule; facilitates extensor tone
• Rotatory movement (spinning): activates semicircular canals; powerful facilitator of tone and alertness
• Inverted positioning: strong vestibular facilitator; used in Sensory Integration therapy

4.4 Visual Input

• Tracking activities develop oculomotor control and visual-motor coordination
• Visual feedback (mirrors, screen) augments proprioceptive learning

---

5. FAMILY-CENTRED CARE IN DEVELOPMENTAL FACILITATION

• Parent/caregiver coaching: Parents are trained to implement facilitation strategies during daily care routines (bathing, dressing, feeding, play)
• Home programme: Written, illustrated, and video-guided home exercise programmes
• Goal setting: Canadian Occupational Performance Measure (COPM) used to identify goals the child and family consider most important
• Goal Attainment Scaling (GAS): Objective measurement of progress toward individually set goals
• Sibling involvement: Engaging siblings in play activities incorporating therapeutic movements

---

6. AUGMENTATIVE TECHNOLOGIES IN DEVELOPMENT FACILITATION

---

7. SPECIFIC FACILITATION STRATEGIES BY DIAGNOSIS

7.1 Cerebral Palsy (CP)

• Most common neuromotor disorder in childhood: ~2/1000 live births. "The most common neuromotor disorder in childhood" (Bradley & Daroff's, p. 2276)
• Facilitation goals: normalise tone, facilitate milestone acquisition, prevent secondary deformity, maximise function at each GMFCS level
• Constraint-Induced Movement Therapy (CIMT): for unilateral CP - restraint of less-affected limb forces use of weaker limb. Meta-analysis (Merino-Andrés et al., Child Care Health Dev, 2024 [PMID 38606885]): effective in 0-6 years for upper limb function

7.2 Down Syndrome (Trisomy 21)

• Hypotonia (central), ligamentous laxity, atlantoaxial instability
• Facilitation: joint compression and approximation to increase co-contraction; graded resistance activities; hydrotherapy to reduce gravitational load

7.3 Hypoxic-Ischaemic Encephalopathy (HIE) / Acquired Brain Injury

• Therapeutic hypothermia reduces secondary neuronal death in neonates
• Post-HIE: early sensory-motor enrichment (skin-to-skin, tactile stimulation, positioning in midline); avoid sensory deprivation

7.4 Autism Spectrum Disorder (ASD) - Motor Component

• Dyspraxia, sensory processing difficulties, poor postural stability
• Facilitation: sensory integration therapy (Ayres), vestibular-proprioceptive enrichment, structured motor skill training in predictable environment

QUESTION 3 (PART B): CONGENITAL AND ACQUIRED DISORDERS AFFECTING GROWTH AND DEVELOPMENT OF THE CHILD

---

INTRODUCTION

---

SECTION A: CONGENITAL DISORDERS

1. CEREBRAL PALSY (CP)

1. Disorder of movement and posture (spasticity, dystonia, weakness)
2. Reliable evidence of disturbance in the fetal/infant brain
3. No evidence of progression
4. Significant functional limitation
5. Lifelong disorder

• Prevalence: ~2/1000 live births for term infants; 40-60/1000 in infants born <32 weeks gestation
• Black children have higher prevalence; this disparity is mediated by socioeconomic and perinatal factors (Harriet Lane Handbook, p. 333)
• 85-90% congenital CP; 10-15% acquired CP

• Prenatal: Cortical malformations, genetic/chromosomal (10-14% of CP has monogenic or chromosomal variant), TORCH infections (toxoplasmosis, rubella, CMV, herpes), stroke, metabolic disease
• Perinatal: Hypoxic-ischaemic encephalopathy (HIE), periventricular leukomalacia (PVL) in premature infants, intraventricular haemorrhage
• Postnatal (up to 2 years): Meningitis/encephalitis (second most common cause of acquired CP), perinatal stroke, abusive head trauma, kernicterus (bilirubin toxicity - causes dyskinetic CP via basal ganglia damage) (Bradley & Daroff's, p. 2282-2283)

• Spastic CP (~80%): Velocity-dependent increase in tonic stretch reflexes; exaggerated tendon jerks; Babinski sign; positive UMN features
  • Spastic diplegia: legs > arms; associated with PVL in premature infants
  • Spastic hemiplegia: one side of body, arm > leg; associated with perinatal stroke
  • Spastic quadriplegia: all four limbs + trunk + face; most severe
• Dyskinetic CP (~15%): Involuntary, uncontrolled, recurring movements; basal ganglia/thalamic damage; associated with HIE at term, kernicterus
  • Dystonic: sustained muscle contractions, twisting postures
  • Choreoathetoid: involuntary writhing movements (athetosis) and brief, irregular jerks (chorea)
• Ataxic CP (~5%): Cerebellar pathology; poor coordination, dysmetria, intention tremor
• Mixed: Combination of above types

• Level I: Walks without limitations
• Level II: Walks with limitations
• Level III: Walks using hand-held mobility device
• Level IV: Self-mobility with limitations; may use powered mobility
• Level V: Transported in manual wheelchair "Importance is on usual rather than best motor performance in a variety of settings: home, school, and community." (Bradley & Daroff's, p. 2269)

• Epilepsy: ~35%
• Intellectual disability: ~50% of quadriplegic CP
• Visual impairment (strabismus, cortical visual impairment)
• Hearing loss
• Feeding difficulties/dysphagia
• Drooling (oromotor incoordination)
• Behavioural/psychological difficulties

• Poor linear growth and low BMI due to reduced caloric intake, dysphagia, high energy expenditure from spasticity and involuntary movements
• Scoliosis (especially GMFCS IV-V), hip displacement, equinus foot deformity

• Equinus deformity: "the most common foot and ankle deformity in patients with cerebral palsy, affecting 70% of children" (Campbell's Operative Orthopaedics, p. 1579)
• Hip displacement: progressive lateral migration due to adductor and hip flexor spasticity
• Scoliosis: especially in non-ambulant CP; can compromise respiratory function
• Crouch gait: often iatrogenic after inappropriate tendon lengthening

• Spasticity management: oral baclofen, tizanidine, dantrolene for widespread spasticity; BoNT-A (botulinum toxin A) for focal/segmental spasticity - "targeted injections combined with rehabilitative therapies can allow for improved motor functioning and delay/avoidance of orthopedic surgery" (Bradley & Daroff's, p. 2397)
• Intrathecal Baclofen (ITB): for widespread spasticity not responsive to oral medications; delivered via pump to CSF at fraction of oral dose; reversible (Bradley & Daroff's, p. 2400-2403)
• Selective Dorsal Rhizotomy (SDR): irreversible partial sensory deafferentation; 25-40% of dorsal rootlets resected; ideal candidate - spastic diplegia, GMFCS I-III, PVL on MRI, age 4-10 years; followed by intensive physiotherapy for 6-12 months (Bradley & Daroff's, p. 2413-2417)
• Deep Brain Stimulation (DBS): for severe dyskinetic CP (Harriet Lane, p. 334)
• Orthotics (AFOs), serial casting, gait training, hydrotherapy, hippotherapy

---

2. SPINA BIFIDA / MYELOMENINGOCELE

• Spina bifida occulta: Only bony defect; no neurological involvement; often incidental finding
• Meningocele: Meninges herniate through bony defect; cord usually intact; good prognosis
• Myelomeningocele: Both spinal cord and meninges herniate; causes neurological deficit below the level of the lesion

• Motor paralysis: flaccid paraplegia below the lesion level (lumbar or sacral most common)
• Sensory loss: anaesthesia below lesion; risk of pressure sores
• Neurogenic bladder: incomplete emptying, overflow incontinence, risk of UTI and renal damage
• Neurogenic bowel: constipation or incontinence
• Hydrocephalus: Occurs in 80-90% of myelomeningocele cases due to Arnold-Chiari II malformation (hindbrain herniation blocking CSF flow); requires ventriculo-peritoneal (VP) shunt
• Arnold-Chiari II malformation: brain stem displacement and cerebellar tonsillar herniation through foramen magnum; can cause stridor, apnoea, dysphagia, upper limb weakness

• Delayed motor milestones depending on lesion level (thoracic: no walking; lumbar 3-4: walking with KAFOs; sacral: near-normal gait)
• Intellectual function: usually normal unless hydrocephalus is poorly controlled; hydrocephalus can cause learning difficulties, attention deficits, visual-perceptual problems
• Social and emotional development impacted by dependency, repeated hospitalisation, medical complexity

• Prevention of contractures: early passive ROM exercises, positioning, splinting
• Strengthening of innervated muscles: progressive resistance exercise for hip flexors, knee extensors/flexors depending on level
• Mobility training: walking with appropriate orthoses (KAFOs, AFOs, RGOs - reciprocating gait orthoses), crutches, wheelchair
• Skin care education: pressure mapping, pressure-relieving cushions (absent sensation = no pain warning)
• Respiratory physiotherapy if Chiari malformation causes respiratory compromise
• Aquatic therapy: reduces gravitational demands; enables functional movement practice

---

3. DOWN SYNDROME (TRISOMY 21)

• Central hypotonia (low tone throughout body): due to abnormal cerebellar development and cortical organisation
• Ligamentous laxity: Joint hypermobility in all joints; atlantoaxial instability in 10-15% (radiological) and 1-2% (symptomatic) - critical for physiotherapy safety
• Delayed motor milestones: mean walking age ~24 months (range 14-36 months)

• Congenital heart defects (40-50%): AVSD, VSD, ASD
• Hypothyroidism (15-20%)
• Hearing loss (50-70%)
• Visual problems: Brushfield spots, strabismus, nystagmus
• Intellectual disability: mild to moderate in most cases
• Increased risk of early-onset Alzheimer's disease (after age 40)

• Short stature; specific Down syndrome growth charts must be used
• Obesity tendency due to hypotonia, reduced activity, hypothyroidism

• Tone facilitation: joint compression, proprioceptive stimulation to increase co-contraction
• Strengthening: progressive resistance training significantly improves muscle strength, gait speed, and community participation
• Balance training: high-frequency instability; vestibular stimulation, perturbation training
• Sport participation: Special Olympics; aquatics, gymnastics, athletics all beneficial
• Atlantoaxial precautions: avoid extreme neck flexion/extension, contact sports unless cleared radiologically

---

4. DUCHENNE MUSCULAR DYSTROPHY (DMD)

• Males; symptoms begin ~2-4 years
• Proximal muscle weakness: difficulty rising from floor (Gowers' manoeuvre - using hands to walk up thighs to compensate for weak hip extensors and quadriceps)
• Calf pseudohypertrophy (replaced by fat and fibrosis)
• Progressive: loses ambulation typically 8-12 years without corticosteroids; 10-12 years with corticosteroids (prednisolone/deflazacort)
• Cardiomyopathy: Dilated cardiomyopathy; leading cause of death
• Respiratory failure: Progressive respiratory muscle weakness; FVC declines; nocturnal hypoventilation → non-invasive ventilation (BiPAP)

• Delay in motor milestones initially subtle
• IQ slightly below normal population mean (particularly verbal); due to isoform of dystrophin in brain (Dp427 and Dp140)
• Progressive physical disability disrupts educational participation and psychosocial development

• Ambulatory phase: Maintain ambulation as long as possible; stretching of hip flexors, iliotibial band, heel cords (prone hip extension, ankle dorsiflexion); night splints; AFOs for foot drop; avoid fatigue (submaximal exercise only)
• Transition/loss of ambulation: Standing programme (standing frames); prophylactic surgery for equinus; power wheelchair prescription
• Non-ambulatory phase: Prevent scoliosis (thoracolumbar orthosis, surgical fusion when Cobb >20°); prevent contractures; respiratory physiotherapy (assisted cough, breath stacking, manual/mechanical insufflation-exsufflation); psychosocial support

---

5. OTHER CONGENITAL DISORDERS

• Normal development until 6-18 months, then regression - loss of purposeful hand use, development of stereotypic hand-wringing
• Seizures, autonomic dysfunction, scoliosis, breathing irregularities
• Physiotherapy: maintain ambulation as long as possible; scoliosis prevention; respiratory management; communication support

• Severe intellectual disability, minimal speech, happy sociable demeanour, seizures, movement/balance disorder (ataxic gait)
• Physiotherapy: gait training, seizure management, communication devices

• Neonatal hypotonia, failure to thrive; later hyperphagia and obesity
• Physiotherapy: tone facilitation in infancy; fitness training and weight management later

---

SECTION B: ACQUIRED DISORDERS

1. TRAUMATIC BRAIN INJURY (TBI)

• Primary injury: Focal contusion, laceration, diffuse axonal injury (DAI - shearing of axons at grey-white matter interface during rotational acceleration-deceleration)
• Secondary injury: Cerebral oedema, raised ICP, secondary hypoxia/ischaemia, excitotoxicity, seizures

• Mild: GCS 13-15
• Moderate: GCS 9-12
• Severe: GCS 3-8

• Younger children at time of injury have paradoxically worse long-term outcomes because the injury disrupts ongoing brain development
• Post-TBI consequences: motor impairment (hemiplegia, cerebellar ataxia), cognitive deficits (memory, attention, executive function, processing speed), behavioural changes (disinhibition, aggression, emotional lability), communication disorders, epilepsy
• School re-integration often problematic; academic underperformance despite apparently good motor recovery

• Acute phase: Positioning for ICP management (30° head elevation, midline positioning), passive ROM, chest physiotherapy for ventilated children, sensory stimulation programme
• Rehabilitation phase: Tone management (BoNT-A, oral baclofen), mobility rehabilitation, cognitive-motor dual task training, return-to-school planning
• Community phase: Home modification, sports re-integration, fatigue management

---

2. MENINGITIS / ENCEPHALITIS

• Sensorineural hearing loss (most common sequela - 30%)
• Cortical necrosis and stroke (venous sinus thrombosis)
• Hydrocephalus (post-inflammatory obstruction of CSF pathways)
• Epilepsy
• Intellectual regression
• Motor deficits (hemiplegia, quadriplegia)

• Herpes simplex encephalitis (HSV-1): temporal lobe predilection; memory impairment, seizures, hemiplegia
• Japanese encephalitis: movement disorders, cognitive impairment
• ADEM (Acute Disseminated Encephalomyelitis): post-infectious demyelination; motor, sensory, cerebellar deficits

• Early mobilisation to prevent contractures and deconditioning
• Tone management and splinting during acute recovery
• Sensory stimulation programme in disordered consciousness
• Gait rehabilitation; communication augmentation; seizure management protocol

---

3. HYPOXIC-ISCHAEMIC ENCEPHALOPATHY (HIE)

• Perinatal asphyxia causing brain injury via two mechanisms: primary energy failure (immediate) and secondary energy failure (6-24 hours later due to glutamate excitotoxicity, free radical generation, apoptosis)
• Therapeutic hypothermia (33-34°C for 72 hours): reduces secondary energy failure; standard of care for moderate-severe HIE at term; must begin within 6 hours of birth
• Outcomes: full recovery to severe CP or death depending on severity
• Physiotherapy: early neurodevelopmental follow-up from NICU onwards; sensory-motor stimulation; positioning

4. ACQUIRED SPINAL CORD INJURY (SCI)

• Children typically injured via road accidents, falls, sports (diving), or tumours
• ASIA impairment scale: A (complete) through E (normal)
• Unique to children: SCIWORA (Spinal Cord Injury Without Radiographic Abnormality) - more common in children than adults due to ligamentous laxity
• "Clinical effects of spinal cord injury" include loss of voluntary movement, loss of sensation, autonomic dysreflexia, neurogenic bladder/bowel (Adams & Victor's Principles of Neurology)

• Respiratory management (lesions above C4 require ventilatory support)
• Pressure care, positioning, passive ROM
• Locomotor training: body weight-supported treadmill training, FES cycling
• Independence training: transfers, wheelchair skills, adaptive sports

---

5. CHILDHOOD STROKE

• Incidence: ~2-3/100,000 children per year; often unrecognised
• Causes: congenital heart disease (embolic), sickle cell disease, prothrombotic disorders, arteriovenous malformations, moyamoya disease
• Consequences: hemiplegia (more often affects the hand), language disorders (dominant hemisphere), visual field defects, seizures
• Key difference from adult stroke: greater neuroplasticity allows often better recovery, but injury can divert normal developmental trajectories

QUESTION 4: ADVANCED SKILLS IN ASSESSMENT OF PAEDIATRIC NEUROPATHOLOGICAL, NEUROPSYCHOLOGICAL AND NEUROSURGICAL CONDITIONS

---

INTRODUCTION

---

PART A: NEUROPATHOLOGICAL ASSESSMENT

A1. History Taking - A Systematic Approach

• Gravidity and parity; maternal illnesses (diabetes, hypertension, thyroid disease); infections (TORCH); medications and substance use; decreased fetal movements; prenatal ultrasound findings
• Gestational age and birth weight (prematurity is a strong risk factor for CP: incidence of CP in <32 weeks gestation = 8.7% vs 0.6% in late preterm) (Bradley & Daroff's, p. 2284)
• Complications during labour: placental abruption, cord prolapse, emergency caesarean section

• Neonatal seizures, intracranial haemorrhage, respiratory failure, sepsis, hyperbilirubinaemia (kernicterus)
• Admission to NICU; therapeutic hypothermia

• Age at acquisition of: head control, rolling, sitting, standing, walking, first words, two-word phrases, bowel/bladder continence
• Regression: loss of previously acquired skills = urgent red flag; may indicate progressive neurological disease, epileptic encephalopathy, or neurodegenerative disorder
• "It is important to quantify rates of development in motor, language, and visual-motor/problem-solving domains and whether the trajectory has been of continued acquisition of skills, plateuing, or regression." (Bradley & Daroff's, p. 2315)

• Seizure type, frequency, current anti-epileptic drugs
• Previous surgeries, orthopaedic procedures
• Current medications affecting tone/cognition

• Consanguinity (recessive metabolic disorders)
• Similar conditions in siblings or parents (X-linked conditions like DMD, FRAXA)

---

A2. Neurological Examination

• Head circumference: microcephaly (<3rd centile) or macrocephaly (>97th) - both clinically significant
• Posture in supine, prone, sitting, standing: describe resting tone, asymmetries, abnormal postures
• Spontaneous movements: quality and quantity; fidgety movements at 9-20 weeks corrected age are predictive of normal neurological outcome; their absence is highly predictive of CP

• Modified Ashworth Scale (MAS): Most commonly used clinically; grades resistance to passive movement 0-4; does not distinguish neural spasticity from mechanical contracture
• Modified Tardieu Scale (MTS): Gold standard for distinguishing spasticity from contracture; measures muscle reaction at two speeds - slow (V1) and fast (V3); the "spasticity angle" (difference in range at V3 vs V1) quantifies neural contribution to stiffness
• Pendulum test (Wartenberg): For lower limb tone; leg dropped from extended position; number of oscillations and angle of rest compared to normal

• Ability to activate muscles voluntarily against gravity
• Selective motor control: can the child isolate ankle dorsiflexion without hip/knee movement? Selective motor control score: 0 (no selective control) to 2 (normal)

• Deep tendon reflexes: graded 0 (absent) to 4+ (clonus); hyperreflexia with clonus = UMN; hyporeflexia = LMN, myopathy, peripheral neuropathy
• Babinski sign: Present in normal infants until ~12-18 months; persistence or reappearance = UMN sign
• Primitive reflex persistence (pathological beyond expected age):
  • ATNR (Asymmetric Tonic Neck Reflex): beyond 6 months - interferes with midline reaching and rolling
  • Moro reflex: beyond 5 months - prevents bilateral arm use
  • Rooting/sucking: beyond 3-4 months
  • Palmar grasp: beyond 6 months
  • Placing/stepping: normally integrates by 6 weeks
• Righting and equilibrium reactions: their presence and quality indicate cortical maturation:
  • Body-on-body righting (2-3 months)
  • Labyrinthine head righting (3-4 months)
  • Optical righting (4-5 months)
  • Protective extension (anterior 6 months; lateral 7 months; posterior 9 months)
  • Equilibrium reactions in sitting (7-8 months); standing (12-18 months)

• Visual fields, acuity (VI = abducens commonly affected in hydrocephalus/raised ICP)
• Bulbar function: sucking, swallowing, gag reflex - critical for feeding assessment
• Facial symmetry (VII)
• Hearing (VIII): must assess in all children with meningitis, HIE, kernicterus
• Tongue movement and dysarthria (XII, X)

• Video-based; assess from anterior, posterior, and lateral
• Identify gait deviations: toe walking (equinus), scissor gait (hip adductor spasticity), crouch gait, Trendelenburg sign, circumduction, stiff knee

• Gold standard for surgical planning and post-operative evaluation in CP
• Measures: kinematics (joint angles), kinetics (ground reaction forces, joint moments), dynamic EMG (timing of muscle activation)
• Pre-operative Duncan-Ely test + dynamic EMG + kinematic criterion (decreased peak knee flexion in swing, delay in timing) required to confirm rectus femoris spasticity before rectus transfer (Campbell's Orthopaedics, p. 1576)
• Gait Deviation Index (GDI), Normalcy Index, Energy Expenditure Index derived from gait data

---

A3. Neuroimaging (Collaborative Interpretation)

• Essential in all children with suspected CP; abnormal in 70-90% (Harriet Lane, p. 334)
• "Imaging generally correlates with the findings on clinical examination and/or etiology, with involvement of the pyramidal tract in spastic cerebral palsy and of the basal ganglia or cerebellum in dyskinetic or ataxic subtypes" (Bradley & Daroff's, p. 2327)
• PVL (periventricular leukomalacia): premature infants; seen as periventricular white matter signal change/volume loss
• Cortical/subcortical lesions: stroke pattern; focal lesions in hemiplegia
• Basal ganglia/thalamic lesions: dyskinetic CP from HIE at term; kernicterus
• Diffuse axonal injury: TBI; appears on diffusion-weighted imaging (DWI) and FLAIR
• Myelination milestones on MRI: myelin should be complete by 2-3 years; delayed myelination = developmental delay

• Used in NICU for premature infants; detects IVH and PVL
• Papile grading of IVH:
  • Grade I: germinal matrix bleed
  • Grade II: IVH without ventricular dilatation
  • Grade III: IVH with ventricular dilatation
  • Grade IV: parenchymal extension (worst prognosis)

• Essential for epilepsy characterisation, surgical planning (interictal discharge localisation), and prognostication in encephalopathy
• Amplitude-integrated EEG (aEEG): bedside monitoring in NICU; seizure detection

---

PART B: NEUROPSYCHOLOGICAL ASSESSMENT

B1. Domains and Standardised Tools

• Child Behavior Checklist (CBCL - Achenbach): Internalising and externalising behaviour; parent and teacher versions
• Strengths and Difficulties Questionnaire (SDQ): 4-17 years; brief screening tool
• Children's Depression Inventory (CDI)

B2. Special Populations in Neuropsychological Assessment

• Pre-surgical neuropsychological evaluation is mandatory before temporal lobectomy or hemispherectomy
• Determines lateralisation/localisation of language and memory function
• Wada test (intracarotid amobarbital test): Hemispheric language and memory dominance; used when fMRI is inconclusive or child is too young
• fMRI language mapping: Non-invasive; activates language areas using verbal tasks; increasingly replacing Wada test
• SEEG/EEG telemetry: Ictal and interictal discharge localisation
• Post-operative monitoring of cognitive change; neuroprotection goals

• Longitudinal cognitive monitoring critical; late effects of cranial irradiation include white matter changes, intellectual decline (processing speed most vulnerable), attention deficits, memory problems
• Growth hormone deficiency (hypothalamic-pituitary radiation damage) affects physical growth and development

• Formal neurodevelopmental follow-up at 2 years corrected age (BSID-IV)
• School-entry assessment (WISC-V, Movement ABC, CBCL)
• High rates of attention difficulties, learning disabilities, and cerebral palsy

---

PART C: NEUROSURGICAL ASSESSMENT IN PAEDIATRIC PHYSIOTHERAPY

C1. Pre-Operative Assessment

• GMFCS Level I-III (good functional ambulation potential)
• Spastic diplegia on MRI showing PVL in setting of prematurity with sparing of basal ganglia and thalamus
• Good selective motor control (can isolate joint movements)
• Preserved strength (SDR removes spasticity but reveals underlying weakness)
• Absence of significant dystonia (dystonia will worsen without spasticity)
• Good cognitive and behavioural capacity for intensive post-operative physiotherapy
• 3D-CGA: baseline kinematic and kinetic data, dynamic EMG
• Family education: SDR is irreversible; post-operative physiotherapy must be intensive for 6-12 months (Bradley & Daroff's, p. 2413-2415)

• Trial intrathecal baclofen bolus to confirm response
• GMFCS assessment; adequate trunk control for pump placement
• Rule out contraindications: anticoagulation, infection, spinal abnormality
• Baseline spasticity scores: MAS, MTS, spasm frequency score
• Caregiver and patient burden questionnaires (RIC-CareQ)

• Confirm predominantly dystonic phenotype
• BFMDRS (Burke-Fahn-Marsden Dystonia Rating Scale) baseline
• MRI to confirm basal ganglia target anatomy

• Head circumference charts
• Fundoscopy (papilloedema from raised ICP)
• Baseline developmental assessment before and after shunting

C2. Post-Operative Assessment

• Daily tone assessment (MAS/MTS at multiple joints) in the first 2 weeks: rapid spasticity reduction expected
• Strength testing: reveals underlying weakness previously masked by spasticity
• Gait re-assessment at 6 months and 12 months post-operatively; compare with baseline 3D-CGA
• "SDR has allowed for ongoing functional ambulation gains in childhood and protects from decline in adolescents seen on natural history studies" (Bradley & Daroff's, p. 2417)

• Casting protocols, wound inspection, weight-bearing precautions
• Progressive gait rehabilitation with assistive devices
• Serial gait analysis to monitor surgical outcomes (e.g., equinus correction: ankle ROM, dynamic EMG, kinematics compared to pre-operative baseline)

• Posterior fossa syndrome (cerebellar mutism): transient but severe; occurs in 10-25% after medulloblastoma resection; features - mutism, cerebellar ataxia, emotional lability, cognitive dysfunction; physiotherapy for ataxia rehabilitation (Frenkel exercises, trunk stability, functional task practice)
• Monitor for VP shunt complications: sudden headache, vomiting, altered consciousness, sundowning eyes (Parinaud syndrome) = shunt malfunction

QUESTION 5: ADVANCED PHYSIOTHERAPY APPROACHES - NEUROPHYSIOLOGICAL PRINCIPLES, SKILLS OF HANDLING IN VARIOUS APPROACHES AND RATIONALE FOR EFFECTIVE MANAGEMENT

---

INTRODUCTION

---

1. NEURODEVELOPMENTAL TREATMENT / BOBATH CONCEPT (NDT)

1.1 Historical Development

• Systems theory: movement emerges from the interaction of multiple systems (nervous, musculoskeletal, cognitive, sensory, environmental) rather than hierarchical reflex suppression
• Motor learning theory: practice, feedback, and task specificity drive neural adaptation
• ICF framework: goals target activity and participation, not just body function
• Neuroplasticity science: the brain can reorganise in response to appropriately structured sensory-motor experience

1.2 Neurophysiological Principles

• Modification of muscle length and joint alignment (biomechanical effect)
• Alteration of sensory inflow from muscle spindles (Ia afferents), Golgi tendon organs (Ib), and joint mechanoreceptors
• Indirect modification of excitatory and inhibitory synaptic activity at spinal and supraspinal levels
• "Therapists are affecting changes in both inhibitory and excitatory synapses simultaneously" (European Bobath Tutors Association)

• Proximal KPoC: Head, shoulder girdle, pelvis - influence tone globally, control proximal stability
• Distal KPoC: Hands, feet - fine-tune distal movement; reduce proximal input as proximal control improves
• Sequential progression: maximum proximal → combination → all distal → no support (independence)
• "Proximal to distal key points. This is a way to withdraw your feedback or control over the movements in a gradual way"

• Facilitation: Manual input that guides the CNS to initiate or elect a specific movement strategy; the child is always a co-participant in movement initiation; the therapist reduces external constraints to allow the system to self-organise
• Inhibition/Reflex Inhibiting Postures (RIPs): Positions and movements that reduce the expression of abnormal tone/reflex patterns; e.g., flexing all spastic extensor patterns in a child with quadriplegia reduces gamma motor neuron firing

• Righting reactions: Restore head and trunk to normal alignment in space; mediated by labyrinth, neck, visual, and body-on-body receptors
• Equilibrium reactions: Maintain balance during displacement; cortical and cerebellar mediated; require intact vestibular system; graded displacement on therapy ball, rocker board
• Protective extension reactions: Arm extension to prevent falling; appears anteriorly at 6 months, laterally at 7 months, posteriorly at 9 months

• Efficient force production
• Appropriate length-tension relationships in muscles
• Correct sensory inflow for movement guidance

• Assess current alignment and tone
• Choose appropriate starting posture (symmetrical, midline alignment preferred)
• Position child to maximise access to KPoC while maintaining safety

• Slow, rhythmic passive movement to normalise tone
• Rotational movements: spinal rotation reduces global stiffness and facilitates reciprocal limb movement
• Weight-bearing on affected limbs to facilitate postural tone and co-contraction

• Guide the child through the target movement using KPoC
• Provide minimum necessary assistance (just enough to enable the movement without the child working against it)
• Give clear, graded assistance: passive → active-assisted → active → resisted
• Move from proximal to distal support as the child gains control

• Reduce handling gradually
• Allow the child to attempt the task independently
• Embed in meaningful play activity

1.3 Evidence for NDT

---

2. PROPRIOCEPTIVE NEUROMUSCULAR FACILITATION (PNF)

2.1 Historical Development

2.2 Neurophysiological Principles

• Muscle spindles (Ia and II afferents): respond to muscle length and rate of length change; stretch stimulus amplifies motor neuron recruitment via the stretch reflex
• Golgi Tendon Organs (Ib afferents): respond to muscle tension; activation causes autogenic inhibition of the same muscle and facilitates the antagonist - the basis of hold-relax and contract-relax techniques
• Joint mechanoreceptors (Ruffini, Pacinian): respond to joint position, compression, and distraction; provide proprioceptive input for motor control

2.3 PNF Diagonal Movement Patterns

• D1 Flexion: shoulder Flexion-Adduction-External rotation, elbow flexion, wrist/finger flexion
• D1 Extension: shoulder Extension-Abduction-Internal rotation
• D2 Flexion: shoulder Flexion-Abduction-External rotation (e.g., sword drawing position)
• D2 Extension: shoulder Extension-Adduction-Internal rotation (e.g., sword sheathing)

• D1 Flexion: hip Flexion-Adduction-External rotation, knee flexion, ankle dorsiflexion-inversion
• D1 Extension: hip Extension-Abduction-Internal rotation
• D2 Flexion: hip Flexion-Abduction-Internal rotation, ankle dorsiflexion-eversion
• D2 Extension: hip Extension-Adduction-External rotation

2.4 PNF Techniques

• Adapted for developmental level: diagonal patterns applied in age-appropriate positions (sidelying, sitting, floor play)
• Irradiation: resistance to trunk and pelvis can facilitate weaker limb muscles in CP
• Hold-relax: for contracture management in DMD, CP (gastrocnemius-soleus complex)
• Rhythmic initiation: for children with hypertonia who have difficulty initiating voluntary movement (e.g., dyskinetic CP)

---

3. VOJTA THERAPY (REFLEX LOCOMOTION)

3.1 Historical Development

3.2 Neurophysiological Principles

1. Reflex creeping (Reflexes Kriechen): Activated in prone position; triggers coordinated whole-body movement resembling developmental crawling pattern
2. Reflex rolling (Reflex-Umdrehen): Activated in supine or sidelying; triggers coordinated whole-body rolling with trunk rotation

• Zones on the thorax, iliac crest, heel, and other body regions
• Pressure applied at specific angles and directions activates the pattern
• The therapist maintains the pressure until a reflex motor response is elicited

• Activates postural control mechanisms (righting, equilibrium)
• Facilitates coordination between agonist and antagonist muscle groups
• Improves respiratory coordination, jaw movement, and fine motor hand function
• Recent systematic review (Sánchez-González et al., 2024): "confirms the neurophysiological robustness of Vojta therapy's reflex locomotion mechanisms"
• Head-to-head comparison (Vojta vs NDT Bobath for congenital muscular torticollis, retrospective cohort 2016-2024, n=53): "Vojta showed greater angular improvements versus NDT" (MDPI J Clin Med, 2025)

• Used from birth onwards; even in neonates
• Particularly effective in: CP (early intervention), spina bifida, brachial plexus injuries, torticollis, hip dysplasia
• Involves parents: taught to deliver Vojta stimulation 4-5 times daily in 20-30-minute sessions
• Child may cry during stimulation (due to activation of motor system, not pain); this is often a barrier to acceptance

---

4. SENSORY INTEGRATION THERAPY (Ayres)

4.1 Historical Development

4.2 Neurophysiological Principles

• Vestibular: Balance, spatial orientation, movement detection; processed in brainstem and cerebellum
• Proprioceptive: Joint position sense, muscle tension; processed in cerebellum and sensorimotor cortex
• Tactile: Touch discrimination, protective touch; discriminative touch (dorsal column-medial lemniscal) vs. protective touch (spinothalamic)

4.3 Clinical Application in Paediatric Neurophysiotherapy

• Suspended equipment: swings (linear, rotatory, bolster), trapeze bars (vestibular-proprioceptive input)
• Textured surfaces: vibration plates, tactile trays (sand, rice, playdough) for tactile discrimination
• Lycra suits/compression garments: provide deep proprioceptive input; normalise proprioceptive processing
• Weighted vests, blankets: deep pressure reduces arousal in over-responsive children
• Crash mats, foam pits: for children with hyposensitivity who seek intense proprioceptive input

• ASD (evidence for sensory-enriched motor interventions improving motor and social skills - Scientific Reports 2025)
• Developmental Coordination Disorder (DCD)
• CP with sensory processing difficulties
• Attention Deficit Hyperactivity Disorder (ADHD)
• Learning disabilities with visuomotor deficits

---

5. TASK-ORIENTED / MOTOR LEARNING APPROACH

5.1 Neurophysiological Principles

• Hebbian plasticity: Neurons that fire together wire together; repeated co-activation of sensory and motor pathways strengthens their synaptic connections
• Motor cortex reorganisation: Task-specific practice enlarges the cortical representation of that body part/movement
• Cerebellum: Error-based learning; internal model updating; the cerebellum predicts sensory consequences of movement and corrects errors in real time

5.2 Task-Oriented Therapy in Practice

• Multiple functional stations practising real-life tasks (floor-to-stand, stair climbing, ball skills, obstacle navigation)
• Children rotate between stations with minimal rest
• Systematic review (Faccioli et al., Front Neurol, 2023 [PMID 37305763]) supports evidence-based motor rehabilitation including intensive circuit training

• For unilateral CP: cast or mitt constrains the stronger hand for 6 hours/day
• Intensive shaping of the weaker hand during constraint (30+ hours over 2-3 weeks)
• Reverses learned non-use (the phenomenon whereby the brain progressively ignores the weaker limb due to early reinforcement of compensatory one-handed strategies)
• Meta-analysis (Merino-Andrés et al., 2024 [PMID 38606885]): effective for upper limb function in 0-6 years with unilateral CP

---

6. HYDROTHERAPY / AQUATIC THERAPY

• Buoyancy: Reduces the effect of gravity (Archimedes principle); enables movement that would be impossible on land; reduces weight-bearing load on spastic muscles, allowing greater ROM
• Hydrostatic pressure: Provides uniform deep pressure to the body; reduces oedema; may reduce spasticity through proprioceptive normalisation
• Turbulence: Creates perturbation to balance systems; trains equilibrium responses
• Warmth (33-34°C): Reduces muscle stiffness; inhibits gamma motor neuron activity; reduces pain; improves compliance

• Systematic review of Halliwick concept in CP (Tapia et al., Dev Neurorehabil, 2023 [PMID 37728374]): significant improvements in balance and functional independence
• Meta-analysis (Pauluka et al., Child Care Health Dev, 2025 [PMID 39688349]): aquatic therapy superior to land-based exercise for GMFM improvement in CP
• Systematic review and meta-analysis (Tao et al., PLoS One, 2025 [PMID 40493654]): hydrotherapy significantly improves athletic ability in CP

---

7. HIPPOTHERAPY

• The horse at walk produces a 3D movement of the pelvis (forward-backward, side-to-side, rotational) at ~1 Hz that closely mimics the human pelvic motion during walking
• This repetitive, rhythmic proprioceptive and vestibular input activates spinal CPGs for locomotion and facilitates postural reactions
• Provides sensory integration (vestibular + proprioceptive + tactile from horse's back)
• Motivating and enjoyable: enhances neural drive and engagement

• Systematic review (Plotas et al., Ital J Pediatr, 2024 [PMID 39300490]): significant improvements in motor function in CP children

---

8. RESPIRATORY PHYSIOTHERAPY

• DMD: progressive respiratory muscle weakness; peak cough flow <270 L/min = ineffective cough → secretion retention → pneumonia
• High SCI (C1-C4): diaphragm paralysis; ventilator dependence
• Posterior fossa tumour resection: Chiari malformation; central apnoea
• Spina bifida: Arnold-Chiari II malformation causing central respiratory compromise

• Mechanical insufflation-exsufflation (MI-E, Cough Assist): Applies positive pressure followed by rapid negative pressure to generate cough; gold standard for secretion clearance in DMD
• Breath stacking: Ambu bag used to deliver multiple tidal volumes to increase lung volume (useful in restrictive lung disease)
• Percussion and postural drainage: Gravity-assisted positioning with chest percussion; standard in bronchiectasis
• Respiratory muscle training: Inspiratory threshold loading devices (Threshold IMT) for accessible inspiratory muscles

9. INTEGRATION AND CLINICAL SYNTHESIS

---

QUESTION 6: CLINICAL DECISION MAKING AND EVIDENCE-BASED PRACTICE TO FORMULATE EFFECTIVE ASSESSMENT AND TREATMENT PROGRAM

---

INTRODUCTION

---

1. FRAMEWORK FOR CLINICAL DECISION MAKING

1.1 Hypothesis-Oriented Clinical Algorithm (HOCA)

1. Initial data collection: History, observation, preliminary examination
2. Problem identification: Identify impairments, activity limitations, participation restrictions (ICF)
3. Hypothesis generation: Identify the most likely impairments driving functional limitation
4. Measurement: Select and apply objective outcome measures to test hypotheses
5. Plan: Select interventions targeting identified hypotheses
6. Implement: Execute treatment plan
7. Reassess: Evaluate outcome; confirm or revise hypotheses
8. Revise: Modify plan based on response

1.2 ICF Framework as the Structural Basis of CDM

---

2. STEPS IN FORMULATING AN ASSESSMENT PROGRAMME

2.1 Pre-Assessment Planning

• Review all available medical records, imaging, and previous therapy reports
• Contact referring physician to clarify medical precautions (e.g., atlantoaxial instability in Down syndrome; VP shunt precautions; anticoagulation; recent surgery)
• Ensure appropriate environment (child-friendly, sensory-appropriate, age-appropriate toys)
• Select outcome measures appropriate for: age, diagnosis, GMFCS level, cognitive level, and the specific question being asked

2.2 Structured Assessment Process

• Chief concern: "What is the most important thing you want your child to be able to do?"
• COPM (Canadian Occupational Performance Measure): parent identifies up to 5 occupational performance issues; rates importance, current performance, and satisfaction; administered at baseline and re-evaluation
• Review of systems: sleep, seizures, pain, feeding, communication, behaviour

• Observe child at play (in age-appropriate, motivating context before hands-on examination)
• Note: level of alertness and engagement; spontaneous movement quality; preferred postures; head control; reach patterns; mobility method; communication mode
• Videotape for later analysis and for comparison at re-assessment

• As described in Question 4: tone (MAS, MTS), strength, reflexes, sensation, cranial nerve function
• Joint range of motion (goniometry): hip extension (Thomas test modified), popliteal angle (hamstring length), ankle dorsiflexion (Silfverskiöld test: gastrocnemius vs soleus distinction), shoulder/elbow/wrist ROM

• Gross Motor Function Measure (GMFM-66): standardised, criterion-referenced; 66 items across 5 dimensions (lying/rolling, sitting, crawling/kneeling, standing, walking/running/jumping); interval scale; enables comparison with reference data for GMFCS level
• Manual Ability Classification System (MACS): how children use their hands in daily activities; 5 levels
• Communication Function Classification System (CFCS): 5 levels of communicative function
• Eating and Drinking Ability Classification System (EDACS): dysphagia severity

• 3D Gait Analysis: if surgical planning or evaluation of orthotics
• Neuropsychological assessment: if cognitive, behavioural, or learning concerns
• Nutritional assessment: dietitian input for growth monitoring
• Respiratory assessment: spirometry, peak cough flow (DMD)

---

3. TREATMENT PROGRAMME FORMULATION

3.1 Goal Setting

• SMART: Specific, Measurable, Attainable, Relevant, Time-bound
• Child/family-centred: based on what the child and family identify as priorities
• ICF-aligned: include goals at activity and participation levels, not only body function
• Hierarchical: immediate goals (4-6 weeks), short-term goals (3 months), long-term goals (6-12 months)

• Individual, functional goals are set collaboratively
• 5-point scale: -2 (much less than expected), -1 (somewhat less), 0 (as expected), +1 (somewhat more), +2 (much more)
• T-score aggregates multiple goals; T=50 means goals achieved as expected
• Sensitive to change in paediatric neurological conditions; more responsive than GMFM for individual therapy goals

3.2 Treatment Intensity Planning

• CIMT: 30-60 hours of practice over 2-3 weeks; more hours = better upper limb outcomes (Merino-Andrés et al., 2024)
• SDR post-operative physiotherapy: Daily physiotherapy for minimum 6-12 months to maximise gains from tone reduction (Bradley & Daroff's, p. 2415)
• Aquatic vs land-based: Meta-analysis (Pauluka et al., 2025) shows aquatic superior to land for GMFM; consider for early, intensive therapy

3.3 Treatment Selection Based on Evidence Hierarchy

---

4. CLINICAL REASONING IN COMPLEX CASES

4.1 Determining the Primary Impairment

• Is it spasticity or contracture? Use MTS to distinguish neural (spasticity) from mechanical (contracture) limitation. A large spasticity angle (V3 > V1 by >15°) indicates neural component treatable with BoNT-A or baclofen. Absent difference indicates pure contracture requiring serial casting or surgery.
• Is it weakness or spasticity limiting gait? Spastic diplegia: excessive plantarflexor spasticity in early stance drives the pattern. But reducing spasticity may unmask weakness. SDR candidates must have sufficient strength to tolerate tone reduction.
• Is the cognitive level sufficient for motor learning-based therapy? High-repetition motor learning requires attention, motivation, and some degree of problem-solving ability. In a child with severe intellectual disability, handled facilitation of ADLs in natural contexts may be more appropriate than formal training sessions.
• Is hip displacement occurring silently? Regular hip surveillance (annual pelvic X-ray in non-ambulant CP - "Reimer's migration index") is essential. Displacement may need to be addressed surgically before physiotherapy can be effective in improving gross motor function.

4.2 Re-Assessment and Programme Modification

• Re-assess using the same standardised outcome measures at fixed intervals (typically 3 and 6 months)
• Use GMFM-66 reference charts (GMFCS-specific) to determine whether the child is tracking expected motor development trajectory
• If not making expected progress: question whether the diagnosis is correct (CP vs progressive disorder), whether therapy dose is sufficient, whether there are medical barriers (uncontrolled seizures, pain, nutritional deficiency, depression), or whether goals need revision
• Communicate clearly with the MDT (neurologist, orthopaedic surgeon, OT, SLP, school) to ensure therapy is aligned with the overall rehabilitation plan

4.3 Transition Planning

• At age 5-6: transition to school environment; physiotherapy goals must align with educational priorities (walking to classroom, toileting, PE participation, handwriting)
• Adolescence: GMFCS can worsen with growth spurts and increased body weight; anticipate and address musculoskeletal deterioration pro-actively
• Adulthood transition: from paediatric to adult services; many adults with CP experience loss of function in the 4th-5th decade ("CP aging" - fatigue, pain, progressive musculoskeletal deterioration, reduced walking ability)

---

5. ETHICAL AND PERSON-CENTRED CONSIDERATIONS IN CDM

• Informed consent/assent: Children >7 years should be involved in decisions about their treatment; younger children's preferences (through observation and facial expression) must be respected
• Cultural sensitivity: Family beliefs about disability, rehabilitation, and the role of therapy vary widely; explore and respect family values when setting goals
• Avoiding harm: Intensive therapy must be balanced against fatigue, pain, and the opportunity cost to the child's other developmental experiences (play, school, social life)
• Resource allocation: Not all families can access high-intensity therapy; provide home programmes, parent coaching, and community-based solutions
• Avoiding learned helplessness: Therapy must progressively withdraw support to promote independence; over-handling is counter-therapeutic

---

6. REFLECTIVE PRACTICE AND CONTINUING PROFESSIONAL DEVELOPMENT

• Regularly searching and critically appraising new evidence (Cochrane reviews, PubMed systematic reviews)
• Attending continuing professional development courses (NDT/Bobath, CIMT, Vojta, SDR post-operative protocols)
• Clinical audit: review your own patient outcomes against published benchmarks
• Peer supervision and case discussion
• Participating in research: paediatric neurophysiotherapy needs more high-quality RCTs with standardised outcome measurement
