Practise a clinician-prescribed gaze-stability task with symptom and clarity control
Vestibular adaptation exercises use head movement while maintaining a clear target, but the target, speed, posture, duration and recovery must match a diagnosed condition and clinical plan. This lesson teaches the full session method under a vestibular clinician’s control. Eye-only tracking is not substituted for head movement, and dizziness is not chased as proof of a good dose.
1 · Permission and limits
Know exactly what you may do
2 · Get ready
Gather what you need and check the starting conditions
What you need
- Clinician-selected letter or symbol target at the prescribed distance and size.
- Stable chair or provider-set standing support, timer, symptom scale and exercise record.
- Usual glasses and mobility aids unless the clinician documents a specific change.
Before you start
- Confirm the diagnosis and exact prescription with the clinician; this page supplies no independent dose.
- Clear the area and use the prescribed seated or guarded posture.
- Record baseline dizziness, nausea, headache, vision clarity and balance from 0 to 10 and agree an immediate stop rule.
3 · The method
Follow these steps in order
- Copy the prescription
Write target distance and size, posture, head direction, range, speed cue, duration, rest and stop threshold exactly.
Why: Small configuration changes can alter both adaptation demand and fall risk.
Check: The learner and clinician can read back the same complete prescription.
- Set the target and support
Place the target at the prescribed distance and eye level. Take the prescribed seat or guarded stance with aids in reach.
Why: A stable setup lets the exercise challenge gaze rather than uncontrolled balance.
Check: The target is clear before head movement and the body is protected from a fall.
- Rehearse slowly
Keep eyes on the target and turn the head through the prescribed small range while the clinician observes. The target should remain recognisable.
Why: Familiarisation confirms the learner understands head-plus-eye coordination.
Check: The learner moves the head, not just the eyes, and can still identify the target.
- Run the prescribed block
Start the timer and move at the clinician-set rhythm. Keep the target as clear as possible, breathe normally and report symptoms rather than hiding them.
Why: A consistent block creates a controllable adaptation dose.
Check: Duration, speed cue, clarity and peak symptoms are recorded.
- Stop and recover
Stop at the prescription limit or earlier stop sign, sit or remain supported and time recovery until symptoms return to the clinician-defined band.
Why: Recovery duration is part of dose and may reveal over-provocation.
Check: The record includes peak change and minutes to recovery.
- Review before any progression
The clinician checks execution, functional response and recovery, then keeps or changes one variable only.
Why: Changing one feature preserves attribution and avoids sudden overload.
Check: The next plan names one controlled change or a hold decision.
4 · Worked example
See the whole method used once
Scenario
A vestibular physiotherapist prescribes a seated horizontal gaze-stability block using a large letter at one metre.
Walkthrough
- The prescription specifies seated posture, small comfortable head turns, metronome speed, 20 seconds, two minutes rest and a symptom stop threshold.
- Rosa records baseline dizziness 1/10 and sees the letter clearly.
- She keeps her eyes on the letter while her head turns; the therapist corrects a shoulder turn.
- At 15 seconds the letter blurs and dizziness reaches the agreed stop value, so she stops and records recovery time.
- The therapist shortens the next block rather than telling Rosa to push through.
Result
Rosa performed the prescribed mechanism, respected the stop rule and produced usable dose-response information. The session does not show vestibular strength or justify unsupervised progression.
5 · Right and wrong
Compare correct or safer execution with the common wrong version
| Moment | Right / safer | Wrong / riskier | Why it matters |
|---|---|---|---|
| Mechanism | Move the head while keeping the prescribed target clear. | Move only the eyes between two targets. | Eye-only exercises do not provide the same vestibular adaptation stimulus. |
| Dose | Use clinician-set speed, range and time. | Move faster until dizziness proves the exercise is working. | Symptom intensity is not a valid universal dose target. |
| Posture | Use the prescribed seat, guard and aids. | Stand unsupported to make the task more functional. | Unapproved balance demand adds fall risk. |
| Progression | Change one variable after clinician review. | Increase speed, time, background and stance together. | Multiple changes hide the cause of benefit or adverse response. |
6 · Common mistakes
Spot the error and apply the correction
| Mistake | Fix |
|---|---|
| The shoulders and trunk rotate with the head. | Reduce range and use clinician feedback to isolate the prescribed head turn. |
| The learner stares harder after the target blurs. | Stop or slow according to the prescription and record the blur. |
| Recovery time is omitted. | Time from stop until symptoms return to the defined band. |
| A good day triggers self-progression. | Keep the exact dose until the clinician reviews repeated responses. |
7 · Practice
Turn the steps into a usable skill
First session
- Clinical screen and prescription teach-back.
- Supported setup and baseline symptom record.
- One observed slow rehearsal.
- One short prescribed block.
- Timed recovery and clinician decision.
Repeat plan
Frequency, total daily dose, rest and progression are supplied only by the treating clinician. Every home block, if authorised, logs target, posture, speed, range, duration, peak symptoms and recovery; changes wait for the agreed review.
Progress when
- Target remains recognisable through the declared movement.
- Symptoms and recovery stay within the clinician-set band across repeated blocks.
- The task supports the agreed functional goal without a fall or new symptom.
Do not progress when
- Recovery lengthens or symptoms accumulate across sessions.
- Head movement, posture or target cannot be performed as prescribed.
- There is a new neurological, hearing, visual or severe headache symptom.
8 · Check the result
Measure what changed
Prescribed gaze-stability block completed with clarity and symptom recovery recorded.
How: Record exact target and body configuration, seconds completed, speed cue, whether the symbol stayed identifiable, baseline and peak symptom scores, recovery minutes and assistance.
Good result: The clinician judges execution correct and repeated blocks remain within the predeclared symptom/recovery band while the functional target improves.
This does not prove: It does not establish a stronger vestibular system, diagnosis, safety for driving or motion, or transfer to an undiagnosed condition.
Self-check
- Does the prescription name every dose variable?
- Is the head moving rather than only the eyes?
- Did you record both peak symptoms and recovery?
- Who authorised the next change?
9 · Stop, adapt or get help
Keep the safety boundary practical
Stop and get help
- Stop and obtain urgent assessment for new weakness, facial droop, speech change, severe sudden headache, fainting, chest pain, double vision or inability to stand safely.
- Stop the block for vomiting, fall, marked imbalance, severe headache, new hearing change or symptoms beyond the clinician’s limit.
- Contact the treating clinician if recovery is longer than prescribed, symptoms accumulate or the exercise pattern changes.
Accessibility and adaptations
- Use a large high-contrast target and spoken timing without changing target distance unless prescribed.
- Use seated practice, guarding and usual mobility aids as configured.
- Provide breaks, low-distraction surroundings and a supporter trained in the stop plan.
10 · Evidence and limits
Why these instructions are here
- official guidance
The official clinical practice guideline supports vestibular rehabilitation for diagnosed peripheral vestibular hypofunction and rejects eye-only saccade or pursuit drills as gaze-stability treatment.
Vestibular Rehabilitation for Peripheral Vestibular Hypofunction: An Evidence-Based Clinical Practice Guideline (CPG+) - primary research
A primary study reported recovery of dynamic visual acuity in unilateral vestibular hypofunction under a defined rehabilitation context.
Recovery of dynamic visual acuity in unilateral vestibular hypofunction
Limits
- This method applies only to a clinician-prescribed configuration and diagnosis.
- Provoking stronger symptoms is not evidence of better adaptation.
- The lesson supplies no generic speed, duration or progression dose.
