Cervicogenic Headache (CGH): Pathology, Muscles Involved, and Physiotherapy Treatment

Definition and Background

Cervicogenic headache (CGH) is a secondary headache - one that originates from pathology in the cervical spine and its related structures, with pain referred to the head. The term was introduced by Sjaastad and colleagues in 1983. The International Headache Society published its first diagnostic criteria in 1998, revised in 2004.

CGH is frequently misdiagnosed as migraine due to significant symptom overlap. It is estimated to affect 0.4-4% of the general population and up to 17.8% of chronic headache sufferers.

Pathology and Mechanism

Anatomical Basis

The core mechanism rests on the trigemino-cervical complex (TCC). Primary sensory afferents from cervical roots C1, C2, and C3 converge with afferents from the occiput and trigeminal afferents onto the same second-order neurons in the trigeminal nucleus caudalis of the upper cervical spinal cord. This anatomical convergence means that:

Pain originating in the upper cervical structures is referred to the head and face
Head pain can spread from occipital regions to trigeminal territories (frontal, temporal, orbital regions)

This is why, as Bradley and Daroff's Neurology explains, "the referral of pain observed in cervicogenic headache and migraine reflects the convergence of trigeminal and cervical afferents onto the same neurons in the trigeminal-cervical complex."

Pain-Generating Structures (Sources of CGH)

Per Scott-Brown's Otorhinolaryngology and Bradley & Daroff's Neurology, pain may arise from:

Zygapophyseal (facet) joints - especially C2/C3 (most common), also atlanto-occipital and atlanto-axial joints
Intervertebral discs (C2-C3, C3-C4)
Upper cervical muscles and ligaments - suboccipital muscles, semispinalis capitis, splenius capitis, upper trapezius, SCM
Apophyseal (facet) arthropathy - degeneration of upper cervical facets
Greater and lesser occipital nerves - entrapment or irritation
C2 dorsal root entrapment
Atlantoaxial region pathology (e.g., rheumatoid arthritis)
Ligamentum flavum calcification, hypertrophy of posterior longitudinal ligament

Central Sensitization

Prolonged nociceptive input from cervical structures leads to central sensitization within the trigemino-cervical complex. Sensitized neurons develop:

Lower thresholds for activation
Increased spontaneous activity
Expanded receptive fields

This explains why CGH can produce widespread referred pain, autonomic features (nausea, photophobia), and why it can mimic migraine closely.

Muscles Responsible

The following muscles are primary contributors to CGH, either as direct pain generators (via trigger points, spasm, or myofascial pathology) or as secondary responders to underlying joint/nerve dysfunction:

Primary Muscles

Muscle	Role in CGH
Suboccipital group (rectus capitis posterior major/minor, obliquus capitis inferior/superior)	Directly innervated by C1-C2; trigger points refer pain to the occiput and over the head; restrict upper cervical segmental motion (C0-C1, C1-C2)
Semispinalis capitis	Major C2/C3 innervated extensor; trigger points refer pain to the occiput, temporal, and frontal regions
Splenius capitis and cervicis	Trigger points refer pain unilaterally to the ipsilateral occiput and top of head
Upper trapezius	Trigger points in the upper fibers refer pain to the temple and retro-orbital area; consistently found to be stiff and hypertonic in CGH patients
Sternocleidomastoid (SCM)	Trigger points refer pain to the occiput, vertex, eye, and forehead; can mimic cluster headache
Levator scapulae	Secondary contributor; increased tension with prolonged poor posture
Deep neck flexors (longus colli, longus capitis)	Weakness leads to forward head posture and compensatory hyperactivation of posterior neck muscles, loading the upper cervical joints

Why Muscle Dysfunction Matters

Weakness of the deep cervical flexors is a hallmark finding in CGH. These muscles (longus colli, longus capitis) are postural stabilizers of the cervical spine. Their impairment:

Increases compressive load on posterior cervical structures (facets, discs)
Forces the superficial global muscles (SCM, upper trapezius) into compensatory overactivation
Perpetuates joint irritation and trigger point formation

Clinical Features

Key distinguishing features from migraine:

Pain typically unilateral, starting in the neck/occiput and radiating to the forehead, temple, or orbital region
Triggered or aggravated by neck movement or sustained neck postures
Constant pain with episodic exacerbations (unlike episodic migraine)
Tenderness over the greater/lesser occipital nerves, cervical facet joints, and upper/middle cervical muscles
Does not respond to migraine-specific medications (triptans)
History of head or neck trauma is common

May also have: nausea, vomiting, photophobia, phonophobia, blurred vision (making differentiation from migraine difficult).

Physiotherapy Treatment (Detailed)

Physiotherapy is the cornerstone of non-pharmacological CGH management. Evidence consistently supports a multimodal approach.

1. Manual Therapy

A. High-Velocity Low-Amplitude (HVLA) Spinal Manipulation

Applied to upper cervical segments (C1-C2, C2-C3) and/or thoracic spine
Reduces joint restriction, neurophysiological pain modulation via descending inhibitory pathways
Evidence: Nuñez-Cabaleiro & Leirós-Rodríguez (2022, Headache) systematic review confirmed effectiveness in reducing headache frequency and intensity

B. Joint Mobilization (Maitland/Mulligan techniques)

Grades I-IV cervical mobilization, especially at C2-C3 and C0-C1 levels
Mulligan concept: Sustained Natural Apophyseal Glides (SNAGs) at upper cervical segments - patient performs active movement while therapist applies a gliding force; particularly effective when neck movement reproduces the headache
Less risk than HVLA; appropriate for patients with contraindications to manipulation
Systematic review (Bini et al., 2022, Chiropr Man Therap) showed combined manual therapy + exercise significantly reduces headache intensity and frequency

C. Soft Tissue Techniques / Myofascial Release

Trigger point therapy targeting suboccipital muscles, upper trapezius, SCM, semispinalis capitis
Suboccipital inhibition/release: sustained gentle pressure at the suboccipital triangle to release the rectus capitis and oblique capitis muscles - directly reduces compressive load on upper cervical structures
A 2024 meta-analysis (Lu et al., Pain Res Manag, PMID 38585645) confirmed myofascial release significantly improves CGH

D. Muscle Energy Techniques (METs)

Patient contracts the restricted muscle isometrically against the therapist's counterforce, followed by passive stretch
Targets: suboccipital muscles, SCM, upper trapezius, levator scapulae
Restores full segmental ROM and reduces muscle hypertonicity

2. Exercise Therapy

A. Deep Neck Flexor (DNF) Training - Craniocervical Flexion Exercise (CCFE)

Targets longus colli and longus capitis using a pressure biofeedback unit (Stabilizer) or ultrasound feedback
Patient performs nodding motion (craniocervical flexion) at 5 progressive pressure levels (20-30 mmHg)
Considered the single most evidence-based exercise for CGH
Improves neuromuscular control, reduces compressive load on upper cervical joints
Jull et al.'s landmark RCT demonstrated that DNF training combined with manual therapy is superior to either intervention alone

B. Cervical Stabilization and Postural Exercises

Progressive resistance exercises for deep and superficial cervical extensors
Targets: semispinalis cervicis, multifidus (cervical), longissimus capitis
Addresses the motor control impairment seen in CGH - reduced activation of cervical multifidus and altered muscle recruitment patterns

C. Scapular and Thoracic Exercises

Serratus anterior and lower trapezius strengthening to normalize scapular position
Thoracic extension exercises to counteract forward head posture
A 2024 RCT (referenced in Nature Index) combining cervical mobilization with clinical Pilates showed greater improvements in headache intensity and muscle stiffness (suboccipital and trapezius) than mobilization alone

D. Cervical Stretching

Suboccipital stretch, cervical lateral flexion and rotation stretches
Particular emphasis on stretching upper trapezius and SCM
Neural mobilization/upper cervical neurodynamic techniques for greater occipital nerve entrapment

E. Aerobic Exercise

Low-impact aerobic conditioning (walking, swimming, cycling) reduces central sensitization through endogenous opioid release and improved cardiovascular function

3. Dry Needling

Insertion of fine needles into active myofascial trigger points in suboccipital muscles, upper trapezius, SCM, semispinalis capitis
Reduces local trigger point irritability, improves muscle extensibility
The APTA 2024 network meta-analysis identified spinal manipulation combined with dry needling as one of the most effective intervention combinations for reducing CGH intensity and frequency

4. Postural Correction and Ergonomics

Assessment and correction of forward head posture (FHP) - the most common biomechanical perpetuating factor
For every 1 inch of forward head translation, the effective weight on the cervical spine increases by approximately 10 lbs
Ergonomic modifications: workstation setup, screen height, chair support
Sleep posture: appropriate pillow height to maintain neutral cervical alignment

5. Electrophysical Agents (Adjunctive)

TENS (Transcutaneous Electrical Nerve Stimulation): Pain modulation via gate control; applied to upper cervical paraspinals or over the greater occipital nerve
Therapeutic ultrasound: Deep tissue heating to suboccipital and upper cervical muscles
Low-level laser therapy (LLLT): Reduces inflammation and trigger point activity in superficial cervical muscles
Heat therapy: Reduces muscle spasm and improves tissue extensibility before manual therapy

6. Taping Techniques

Kinesio taping of upper trapezius and cervical paraspinals for muscle facilitation/inhibition
Postural taping to facilitate thoracic extension and correct FHP

7. Education and Self-Management

Pain neuroscience education (PNE): explaining central sensitization mechanisms reduces fear-avoidance and improves outcomes
Home exercise program: DNF exercises, cervical stretching, posture correction
Activity modification and pacing strategies
Relaxation techniques: diaphragmatic breathing, progressive muscle relaxation

Evidence Summary

Intervention	Evidence Level	Effect
Manual therapy (manipulation + mobilization)	Systematic Review (Nuñez-Cabaleiro 2022)	Reduces frequency and intensity
Manual therapy + exercise (combined)	Meta-Analysis (Bini et al. 2022)	Superior to either alone
Myofascial release	Meta-Analysis (Lu et al. 2024, PMID 38585645)	Significant improvement
Dry needling + manipulation	Network meta-analysis (APTA 2024)	Most effective combination
DNF training (Craniocervical flexion)	Multiple RCTs	Reduces disability and frequency
Spinal manipulation alone	Systematic Review	Effective vs sham
Mulligan SNAGs	Systematic Review (Aslyuce 2022)	Positive effects on CGH

Physiotherapy Clinical Pathway

Assessment: C0-C3 segmental mobility testing, DNF endurance test, postural assessment, trigger point palpation, provocative testing (manual pressure reproducing headache), diagnostic nerve blocks if needed
Acute phase (weeks 1-3): Manual therapy (mobilization/manipulation), soft tissue release, pain education, TENS/heat
Rehabilitation phase (weeks 3-8): DNF training, cervical stabilization exercises, postural correction, ergonomic advice, Mulligan SNAGs
Maintenance phase (8+ weeks): Progressive loading, aerobic conditioning, self-management, return to activity

Vertigo: Types, Pathology, and Physiotherapy Exercises with Doses

1. What is Vertigo?

Vertigo is the false sensation of movement - the illusion that the self or the environment is spinning, rotating, or tilting - caused by a mismatch between vestibular, visual, and proprioceptive sensory inputs. It is distinct from general dizziness, lightheadedness, or presyncope.

Classification:

Peripheral vertigo: Arises from the inner ear (labyrinth) or vestibular nerve (CN VIII). Generally more intense, with a latency before nystagmus onset, nystagmus that fatigues, and prominent nausea.
Central vertigo: Arises from brainstem or cerebellum. Often milder spinning sensation, nystagmus begins immediately without latency, does NOT fatigue, may have vertical nystagmus.

2. Common Causes of Vertigo

Cause	Characteristics
BPPV (Benign Paroxysmal Positional Vertigo)	Brief (<1 min) episodes triggered by head position change
Vestibular neuritis	Acute severe vertigo lasting days; no hearing loss
Labyrinthitis	Like neuritis but WITH hearing loss
Meniere's disease	Recurrent attacks: vertigo + tinnitus + fluctuating hearing loss + aural fullness
Vestibular migraine	Episodic vertigo (minutes to hours) with migraine features
Central (cerebellar/brainstem)	Stroke, MS, tumor - no fatigue of nystagmus

3. Pathophysiology

BPPV - the most common cause of vertigo - results from calcium carbonate crystals (otoconia/otoliths) dislodged from the utricular macula migrating into one of the semicircular canals (most commonly the posterior canal in 80-90% of cases). When the head moves, gravity causes these free-floating particles to move within the canal, creating abnormal endolymph flow and cupular deflection, generating nystagmus and vertigo (Harrison's Principles of Internal Medicine, 22nd ed., p. 207).

Vestibular neuritis/hypofunction: Inflammation (often viral) of the vestibular ganglion/nerve causes sudden unilateral loss of vestibular input. The asymmetric tonic firing between the two labyrinths produces the sensation of rotation toward the affected side and compensatory nystagmus.

Central vestibular compensation - the principle behind all vestibular rehabilitation: After a peripheral lesion, the CNS undergoes neuroplastic adaptation through three main mechanisms:

Adaptation - the vestibulo-ocular reflex (VOR) gain is recalibrated
Habituation - repeated exposure to provocative stimuli reduces CNS response
Sensory substitution - the CNS learns to rely on visual and proprioceptive inputs to substitute for impaired vestibular function

4. Physiotherapy (Vestibular Rehabilitation) - Full Detail with Doses

Vestibular rehabilitation was pioneered by Cooksey and Cawthorne in the 1940s for post-operative dizziness. Modern programs are individualized based on diagnosis, as established by Cummings Otolaryngology.

A. BPPV - Canalith Repositioning Maneuvers (CRMs)

These are the primary treatment for BPPV and work by using gravity to move displaced otoconia out of the semicircular canals back into the vestibule.

1. Epley Maneuver (Modified) - For Posterior Canal BPPV

Most used and most evidence-supported maneuver. Success rate: 50-90% per single session; up to 90%+ with repetition.

Here is the step-by-step procedure (illustrated below from Harrison's Principles of Internal Medicine, 22nd ed.):

Modified Epley Maneuver - Steps for Right and Left Posterior Canal BPPV

Modified Epley maneuver (top row: right ear BPPV; bottom row: left ear BPPV) — Harrison's Principles of Internal Medicine, 22nd ed.

For RIGHT posterior canal BPPV:

Step	Position	Hold Time
1	Patient sits upright, head turned 45° toward the RIGHT (affected) ear	Briefly
2	Therapist supports head; patient lies back rapidly to supine with head extended 20-30° below the table edge (head still turned 45° right) - Dix-Hallpike position. Wait for nystagmus.	30 seconds (or until nystagmus stops)
3	Without lifting the head, rotate it 90° to the LEFT (nose now points left at 45°)	30 seconds
4	Roll the entire body to the left side, simultaneously rotating the head another 90° so the nose points 45° downward toward the floor	30 seconds
5	Patient is slowly brought to sitting upright	Rest briefly, then repeat to confirm resolution

Dose: Repeat maneuver until no nystagmus is elicited. Typically 1-3 repetitions per session. One session is often sufficient; if not, repeat at the next visit.

Post-maneuver instructions (traditional): Some clinicians advise patients to remain upright for 48 hours and avoid sleeping on the affected side for 1-2 days to prevent re-entry of debris into the canal. However, recent evidence does not firmly support strict post-maneuver positioning restrictions.

For LEFT posterior canal BPPV: All directions are mirrored.

2. Semont (Liberatory) Maneuver - For Posterior Canal BPPV

Alternative to Epley, with similar efficacy. Preferred when patient has cervical spine restrictions.

Step	Position	Hold Time
1	Patient sits upright on the edge of the table, head turned 45° AWAY from the affected ear	Briefly
2	Rapidly move the patient to lie on the side of the AFFECTED ear (the one causing vertigo), with head maintained in the rotated position	30 seconds (or until nystagmus resolves)
3	Rapidly swing the patient (in one fast, sweeping motion) to lie on the OPPOSITE side, keeping the head in the same relative position (nose now points toward the floor)	30 seconds
4	Slowly return to seated upright	-

Dose: 1-3 repetitions per session. Repeat sessions as needed over 1-2 weeks.

3. Horizontal Canal BPPV - Log Roll (Barbecue/Lempert Maneuver)

For the less common horizontal canal variant. Nystagmus is horizontal and changes direction with each side.

Step	Position	Hold Time
1	Patient lies supine, head turned toward the affected ear	30 seconds
2	Turn head to face straight up (supine)	30 seconds
3	Turn head 90° toward the UNAFFECTED ear	30 seconds
4	Roll body and head further so patient is face-down (prone)	30 seconds
5	Roll to lie on unaffected side	30 seconds
6	Return to sitting	-

Alternatively, forced prolonged positioning: lying on the UNAFFECTED side for 12 hours can resolve geotropic horizontal canal BPPV in many cases.

4. Brandt-Daroff Exercises - For BPPV (Habituation-Based)

Designed to habituate the CNS to the provocative position and can also mechanically dislodge debris. Used as a home exercise or as adjunct when repositioning maneuvers are not fully effective.

Technique:

Start in sitting position on the edge of a bed
Turn head 45° toward the affected side
Rapidly lie down sideways onto the AFFECTED ear (body goes down to the opposite side) - head remains turned 45° up relative to the bed
Hold until vertigo resolves + an additional 30 seconds (minimum)
Return to sitting, wait until dizziness subsides
Turn head 45° toward the OTHER side, lie down on the OTHER side
Hold 30 seconds, return to sitting

Dose:

5-10 repetitions per set
3 sets per day (morning, afternoon, evening)
If severe nausea: reduce to 3 repetitions × 3/day until tolerance improves
Continue until 2 consecutive days with no vertigo
Typical duration: 2 weeks

Evidence: A 2024 systematic review (Alashram AR, Eur Arch Otorhinolaryngol, PMID 38341824) confirmed Brandt-Daroff exercises are effective for BPPV, though repositioning maneuvers remain superior.

B. Vestibular Adaptation Exercises (VOR Rehabilitation)

Used primarily for unilateral vestibular hypofunction (UVH) - after vestibular neuritis, labyrinthitis, acoustic neuroma resection, or chronic uncompensated vestibular loss. These exercises drive neuroplastic VOR recalibration through retinal slip signals.

Recovery time: 6-8 weeks average with active vestibular rehabilitation.

1. VOR X1 (Times 1) - Gaze Stabilization

Goal: Improve the vestibulo-ocular reflex gain and reduce oscillopsia (blurred vision with head movement).

Technique:

Patient holds a business card or a fixed target (letter/word) at arm's length
Focuses on the target
Oscillates the head horizontally (left-right) as fast as possible while keeping the letter clear and in focus
If target blurs, the patient slows down
Then repeat in the vertical plane (up-down)

Starting Dose:

1-2 minutes per direction (horizontal + vertical)
3 times per day
Target must remain in focus - the key requirement

Progression:

Increase to 5 minutes per direction
Add a distracting background (checkerboard, venetian blinds pattern behind the card)
Vary head speed and amplitude
Progress from sitting → standing → walking

2. VOR X2 (Times 2) - Advanced Gaze Stabilization

Goal: Greater VOR gain improvement than X1.

Technique:

Same as X1 but the target moves in the OPPOSITE direction to the head
Head moves right → target moves left; head moves left → target moves right
Eyes must keep focus on the moving target despite double the retinal demand

Dose:

Begin only after X1 is well tolerated
1-3 minutes × 3/day
Progress in the same manner as X1

3. Imaginary Target (Head Impulse) Exercise

For patients who cannot tolerate physical target tracking:

Patient closes eyes, imagines a fixed target
Rapidly rotates head side to side for 1-2 minutes
Builds VOR pathway independent of visual input

C. Habituation Exercises (Cawthorne-Cooksey Exercises)

Used when specific movements or positions consistently provoke dizziness. The principle is controlled, repeated exposure to the provocative stimulus, causing the brain to progressively reduce its response. Used for vestibular neuritis, chronic vestibular dysfunction, and post-concussion vestibular symptoms.

The classic Cawthorne-Cooksey program progresses through three stages:

Stage 1 - Lying Down (Bed Exercises)

Exercise	Repetitions	Frequency
Eye movements: up-down, side-side (slow then fast)	5-10 reps each direction	3-4×/day
Eye movements: focus on moving finger near to far (20 cm to arm's length)	10 reps	3-4×/day
Head movements: bend forward, backward, side-to-side (slow, then fast - eyes open, then closed)	5 reps each, slowly increasing	3-4×/day
Head rotation (ear to shoulder)	5-10 reps	3-4×/day

Hold each position that provokes dizziness for 20-30 seconds. The dizziness should habituate.

Stage 2 - Sitting (Chair Exercises)

Exercise	Repetitions	Frequency
All Stage 1 eye and head movements	Same dosing	3-4×/day
Shoulder shrugging and circling	10 reps	3×/day
Bending forward and picking up objects from the floor	10 reps	3×/day
Head turning side to side with a target (gaze stabilization)	1-2 min	3×/day

Stage 3 - Standing and Gait Exercises

Exercise	Repetitions/Duration	Frequency
Standing feet together, eyes open then closed (Romberg)	30 seconds each	3-5×/day
Tandem stance (heel-toe) eyes open then closed	20-30 seconds	3×/day
Single-leg stance eyes open then closed	10-20 seconds each leg	3×/day
Walking across the room eyes open (then closed against a wall for safety)	10 passes	3×/day
Walking with head turning side to side (VOR-gait integration)	2-5 minutes	3×/day
Turning around while walking (180° turns)	5-10 turns	3×/day
Throwing a ball from hand to hand while walking	2-3 minutes	2×/day
Walking on foam/uneven surfaces	2 minutes	2×/day
Stair climbing	2-3 flights	Daily

General Dose for Cawthorne-Cooksey: Each exercise should be performed to the point of mild-to-moderate symptom provocation (rated 2-5/10 on dizziness scale). Symptoms should resolve within minutes of stopping. If symptoms persist >20 minutes after exercise, reduce intensity.

D. Balance and Postural Control Exercises

Used across all vestibular diagnoses to reduce fall risk and improve functional stability.

Modified CTSIB (Clinical Test of Sensory Integration in Balance)

Progressively challenges the three sensory systems (vestibular, visual, proprioceptive):

Condition	Surface	Vision	Challenge Level
1	Firm	Eyes open	Easy (all three systems)
2	Firm	Eyes closed	Removes vision
3	Firm	Visual conflict (dome)	Disrupts vision
4	Foam	Eyes open	Removes proprioception
5	Foam	Eyes closed	Removes vision + proprioception
6	Foam	Visual conflict	Maximum challenge

Dose: Each condition for 20-30 seconds, repeated 3 times per condition. Progress from condition 1 to 6 over weeks.

Weight Shifting and Perturbation Training

Anterior-posterior and mediolateral weight shifts on stable and unstable surfaces
Dose: 10-15 repetitions, 2-3 sets, 3×/day

E. Gait Rehabilitation Exercises

Specifically for patients with functional gait impairment from chronic vestibular dysfunction:

Exercise	Dose
Walking with head turns (horizontal then vertical)	5-10 minutes, 2-3×/day
Tandem (heel-toe) walking	3-5 passes × 3 sets/day
Walking with eyes closed (near a wall for safety)	5-10 passes × 2/day
Obstacle course walking	5-10 minutes/session, daily
Figure-of-8 walking	5 circles × 3 sets/day
Dual-task gait (e.g., counting backward while walking)	2-5 minutes/session

5. Exercise Progression Principles

From Cummings Otolaryngology and VestibularFirst guidelines (2025):

Change one variable at a time (surface, speed, head movement, cognitive load)
Progress when symptoms are brief and recover quickly - not when they are prolonged beyond 20 minutes
Start with stable surface → foam → uneven ground
Start seated → standing → walking → dynamic tasks
Eyes open → eyes closed → visual conflict environments
Single task → dual task (cognitive + motor simultaneously)

6. Diagnosis-Specific Program Summary

Condition	Primary Intervention	Duration
BPPV (posterior canal)	Epley or Semont maneuver	1-3 sessions, with home Brandt-Daroff ×3/day ×2 weeks
BPPV (horizontal canal)	Log roll / barbecue maneuver	1-3 sessions
Vestibular neuritis (acute)	Rest 24-48h then VR begins: X1 VOR exercises + Cawthorne-Cooksey	6-8 weeks
Unilateral hypofunction (chronic)	VOR X1/X2 + gaze stability + balance training	8-12 weeks
Bilateral hypofunction	Balance/gait training; NO habituation exercises (no functional vestibular system to habituate)	Long-term/lifelong
Meniere's disease (stable phase)	Sensory substitution + fall prevention training	Individualized
Vestibular migraine	VR (2026 systematic review PMID 41840297 confirms efficacy) + migraine prophylaxis	8-12 weeks
Central vertigo (post-stroke)	Task-specific gait + dual-task training; caution with VOR exercises	12+ weeks

7. Contraindications / Precautions

Acute BPPV during a vertigo episode: wait until acute phase (nausea/vomiting) passes before rehabilitation
Unstable or actively progressing central lesion: avoid aggressive VOR exercises until stabilized
Cervical spine instability: modify or avoid Epley/Semont - use Brandt-Daroff instead
Vestibular suppressant medications (diazepam, meclizine): reduce or stop before VR - they delay CNS compensation by suppressing the very asymmetric signal needed for recalibration (Cummings Otolaryngology)
Meniere's disease (unstable/fluctuating phase), superior canal dehiscence, perilymphatic fistula: may NOT benefit from VR and require specialist management first

8. Outcome Measures Used

Dizziness Handicap Inventory (DHI) - 25-item self-report
Activities-Specific Balance Confidence (ABC) Scale - fall fear
Dynamic Gait Index (DGI) - gait with head turns
Timed Up and Go (TUG) - functional mobility
Video Head Impulse Test (vHIT) - objective VOR gain
