Deciding Whether to Mobilize a Patient with an Acute Vestibular Presentation
A 44-year-old woman is seen in an outpatient clinic 2 days after the abrupt onset of severe vertigo, nausea, and imbalance. She reports that the room 'spins' constantly and that she cannot walk without holding the wall. She has no hearing loss, no tinnitus, and no focal weakness or numbness. She has a history of migraine. Vitals: BP 128/78, HR 82, afebrile. On examination: spontaneous right-beating horizontal nystagmus that is suppressed by visual fixation; the head impulse test is positive on the left (corrective saccade seen); no skew deviation on the cover test; no direction-changing nystagmus on gaze; Dix-Hallpike is negative bilaterally; she is unable to stand with feet together with eyes closed. She asks to 'just do the Epley maneuver' because a friend had vertigo.
1. Using the HINTS examination findings, explain what the pattern suggests and why the Epley maneuver is not indicated.

The HINTS battery (Head Impulse, Nystagmus, Test of Skew) is used to distinguish a peripheral from a central cause of acute vestibular syndrome:
- Head impulse test positive on the left (corrective saccade) → consistent with a peripheral vestibular deficit (left horizontal canal/hypofunction).
- Unidirectional, horizontal, right-beating nystagmus that suppresses with fixation → peripheral pattern. Central nystagmus is typically direction-changing and does not suppress with fixation.
- No skew deviation → argues against a brainstem lesion.
This combination (positive head impulse, unidirectional nystagmus, no skew) is the peripheral pattern, most consistent with vestibular neuritis in a patient with acute-onset prolonged vertigo. (The migraine history is a confounder but does not override the exam.)
Why not the Epley maneuver: the Epley maneuver is a canalith-repositioning procedure for posterior canal BPPV, which produces brief (seconds), positional vertigo triggered by head movement, with a positive Dix-Hallpike and typically no spontaneous nystagmus at rest. This patient has continuous vertigo, spontaneous nystagmus, and a negative Dix-Hallpike bilaterally - so BPPV is not the diagnosis. Performing a repositioning maneuver would not address vestibular neuritis and could worsen her nausea. Her request reflects a misunderstanding and should be addressed with education.
2. What is your immediate management decision, and what safety and referral steps are required before starting vestibular rehabilitation?

Decision: proceed with vestibular rehabilitation (habituation and gaze-stabilization exercises, gait and balance training) rather than a repositioning maneuver - but first confirm medical clearance and screen for central causes.
Safety and referral steps:
- Confirm the diagnosis with the referring provider if not already established; acute vestibular syndrome with a peripheral pattern is usually managed medically, and the provider should be aware of the presentation. Document the HINTS findings.
- Screen for red flags that would mandate emergency referral: new focal weakness, dysarthria, dysphagia, diplopia, severe headache, hearing loss, or a change in the nystagmus pattern. She has none - document this.
- Fall safety: she cannot stand with feet together with eyes closed, so provide gait training with a device, home safety education, and clear return precautions.
- Education: explain that vestibular neuritis typically improves over weeks, that the Epley maneuver is not appropriate because this is not BPPV, and that early movement/exercise (not bed rest) speeds compensation.
Judgment being tested: a patient request for a specific procedure must be matched to the examination - the negative Dix-Hallpike and spontaneous nystagmus exclude the indication.
3. Outline the rehabilitation plan and the prognostic factors you would discuss with her.

Plan of care:
- Gaze stabilization (VOR x1/x2 exercises) for the left horizontal canal deficit; progress by speed, background complexity, and target distance.
- Habituation exercises for motion-provoked symptoms.
- Balance and gait training progressing from static to dynamic and from eyes-open to eyes-closed/foam surfaces; address the inability to stand with feet together with eyes closed.
- Functional goals: independent ambulation without a device, return to driving/work, tolerance of head movement.
- Dose: short, frequent sessions (e.g., 2–3 times daily for home exercises) because nausea limits tolerance; monitor symptom intensity and keep it tolerable.
Prognostic discussion:
- Favorable: peripheral vestibular neuritis generally compensates well over 4–6 weeks with active rehabilitation; younger age and early mobilization favor recovery.
- Complicating factors: migraine history (may increase susceptibility to recurrent vestibular symptoms), and the risk of developing secondary anxiety/avoidance if she restricts movement.
- Set expectations: symptoms will not resolve overnight; some residual sensitivity to head movement is common; adherence to the home program is the main driver of recovery.
- Discharge criteria: independent gait and balance, symptom control with daily activities, and a self-managed home program.
