Lymphatic Manipulation - Short Notes (6 Marks)

Definition

Anatomy Relevant to Technique

• Thoracic inlet / supraclavicular fossa - terminal drainage point into the subclavian veins
• Thoracic diaphragm - the thoracic duct crosses at T12, cisterna chyli lies just below
• Femoral triangle
• Popliteal fossa

Physiology of Lymph Propulsion

1. Intrinsic pump - rhythmic spontaneous contractions of lymphatic smooth muscle, modulated by the autonomic nervous system
2. Extrinsic pump - compression/expansion of vessels by joint movement, muscular contraction, myofascial flexibility, respiration, and posture

Types / Techniques

Indications

• Infections (e.g., pneumonia, sinusitis) - improves immune cell delivery and antibiotic distribution; the MOPSE trial showed reduced hospital stay in pneumonia
• Lymphedema (primary and secondary) - reduces interstitial fluid accumulation
• Post-surgical edema - especially after mastectomy with axillary node dissection
• Sprains, strains, acute somatic dysfunction
• Chronic inflammatory and autoimmune conditions - facilitates removal of inflammatory mediators
• Venous stasis / venous insufficiency
• Pregnancy-related edema

Contraindications

• No patient consent
• Active bone fracture at the site

• Acute heart failure - pumping may increase cardiac afterload by rapidly increasing venous return; treat somatic dysfunctions instead
• Malignancy / metastatic cancer - theoretical risk of spreading tumor cells (though evidence for this is disputed in the literature)
• Leukemia / lymphoma - theoretical risk of dissemination
• Active cellulitis or skin infection over the treatment area
• Deep vein thrombosis - risk of embolism

Treatment Sequence (Protocol Approach)

1. Open the thoracic inlet first - ensures terminal drainage into the central venous system is patent
2. Treat spinal transitional zones (craniocervical, cervicothoracic, thoracolumbar, lumbosacral) to restore biomechanical motion
3. Progress from central to peripheral - address truncal lymphatics before limb lymphatics

Mechanism of Benefit (Summary)

• Increases lymphatic flow velocity and volume
• Enhances delivery of immune cells (lymphocytes, macrophages) to tissues
• Improves delivery of antibiotics to infected sites
• Reduces edema by clearing excess interstitial protein and fluid
• Modulates autonomic tone affecting lymphatic vessel contractility

Clinical Pearl

Rib Dysfunction - Muscle Energy Technique (MET)

Definition of MET

Rib Motion Physiology (Basis for Dysfunction Classification)

Types of Rib Dysfunction

• Rib is stuck in the up/elevated/cephalad position
• Cannot move freely into exhalation (cannot move down)
• Key rib = lowest rib of the dysfunctional group (it holds the group up)
• Treatment: engage muscles of exhalation to pull it down

• Rib is stuck in the down/depressed/caudad position
• Cannot move freely into inhalation (cannot move up)
• Key rib = topmost rib of the dysfunctional group (it holds the group down)
• Treatment: engage muscles of inhalation to pull it up

Key Rule: In inhalation dysfunction → treat the bottom rib. In exhalation dysfunction → treat the top rib.

Identification / Diagnosis

• On palpation: the dysfunctional rib has decreased excursion
• Inhalation dysfunction: rib stays high, increased intercostal space below the key rib
• Exhalation dysfunction: rib stays low, decreased intercostal space above the key rib
• Symptoms: chest/thoracic pain, restricted breathing, difficulty taking a deep breath, shortness of breath

MET Procedure - General Steps

1. Position the patient to engage the target rib at the restrictive barrier
2. Place your monitoring hand (thenar eminence or fingertips) on the angle of the key rib
3. Ask the patient to perform a specific muscle contraction (3-5 seconds, ~20% effort)
4. Apply an equal and opposite isometric counterforce - no movement occurs
5. Instruct patient to relax completely (1-2 seconds)
6. On relaxation, take up the new slack (move rib further into restriction)
7. Repeat 3-5 times, then recheck rib motion

MET by Rib Group - Muscle Targets

Exhalation Dysfunction (rib stuck DOWN - use inhalation muscles to lift it)

Inhalation Dysfunction (rib stuck UP - use exhalation muscles to lower it)

• Technique uses a respiratory assist: patient exhales fully while therapist pushes rib caudally; on inhalation, therapist resists the cephalad return
• Intercostal muscles (internal intercostals) and the diaphragm are engaged
• Alternatively, the same muscle attachment groups above are used in reverse - patient exhales against resistance

Indications

• Rib somatic dysfunction (primary)
• Thoracic pain and restricted chest wall mobility
• Respiratory conditions: asthma, COPD, pneumonia (adjunctive)
• Post-surgical chest wall restriction
• Thoracic outlet syndrome (rib 1 involvement)
• Patients where HVLA (high-velocity, low-amplitude) thrust is not suitable (e.g., osteoporosis, frail patients)

Contraindications

Advantages of MET for Rib Dysfunction

• Safe, low-force technique suitable for most patients
• Patient actively participates - improves proprioceptive re-education
• Can be used when HVLA is contraindicated
• Addresses both articular restriction and associated muscle hypertonicity
• Improves lymphatic flow through chest wall motion restoration

Maitland Concept - Short Notes

Background / Who was Maitland?

Definition

"The Maitland Concept emphasises a specific way of thinking, continuous evaluation and assessment, and the art of manipulative physiotherapy - know when, how and which techniques to perform, and adapt these to the individual patient."

The Permeable Brick Wall Model (Core Concept)

Key Philosophical Principles

1. Assessment before treatment - thorough subjective and physical examination guides every decision
2. Continuous re-assessment - treatment response is evaluated after every technique; if there is no change, the technique is modified
3. Patient communication - the patient's subjective experience is central; their words, quality of pain, and functional limitations guide treatment selection
4. Hypothesis testing - clinician forms hypotheses from the assessment and tests them through treatment response
5. "When in doubt, don't" - caution is the default when assessment findings are unclear

Assessment Framework

Subjective Examination

Physical Examination

• Range of motion
• Quality of end-feel
• Pain provocation
• Resistance (stiffness)

The Grades of Mobilization

|----I----|--------II--------|----III----|--IV--|
BEGINNING                              END      LIMIT
OF RANGE                           OF RANGE

• Grades I & II = Pain-dominant states (neurophysiological effect - gate control, descending inhibition)
• Grades III & IV = Stiffness/restriction-dominant states (mechanical effect - stretching capsule, passive tissues)
• Grade V = Manipulation - patient cannot prevent this movement

Types of Passive Movements Used

1. Oscillatory mobilizations - rhythmic, repeated movements (Grades I-IV); most commonly used
2. Sustained mobilizations - held at a specific point to stretch soft tissue or relieve pain
3. Manipulation (Grade V) - high-velocity, low-amplitude (HVLA) thrust; patient cannot stop it once initiated

Selection of Technique

• Pain vs. stiffness dominance (from SIN assessment)
• Stage of condition (acute, subacute, chronic)
• Response to previous treatment
• Patient's tolerance and consent
• Irritability - high irritability = lower grades, fewer repetitions

Indications

• Mechanical joint pain and stiffness (spine and peripheral joints)
• Cervical, thoracic, lumbar spine pain
• Osteoarthritis
• Post-surgical joint stiffness
• Acute or chronic musculoskeletal pain
• Spinal/peripheral joint restriction
• Nerve-related pain (with appropriate neurodynamic testing)

Contraindications

• Fracture at the treatment site
• Active malignancy / bone tumour
• Joint infection / septic arthritis
• Vertebrobasilar insufficiency (for cervical manipulation)
• Spinal cord compression with neurological deficit
• Inflammatory arthritis in acute phase (e.g., active RA)
• Cauda equina syndrome

• Osteoporosis
• Pregnancy (certain regions)
• Bleeding disorders / anticoagulant therapy
• Ligamentous instability

Mechanism of Action

Advantages of Maitland Concept

• Highly individualized and patient-responsive
• Can be used safely across a wide range of grades (Grades I-II are very safe)
• Continuous re-assessment prevents harm and guides progression
• Applicable to all peripheral and spinal joints
• Integrates well with exercise therapy and education
