Efficacy of Vestibular Rehabilitation Following Acute Vestibular Neuritis: A Randomized Controlled Trial.

OBJECTIVE

To investigate whether a vestibular rehabilitation program started early after diagnosis of vestibular neuritis combined with standard care reduces dizziness and improves functions of daily life more effectively than standard care alone in patients with acute vestibular neuritis.

STUDY

DESIGN

Non-blinded, randomized controlled trial with 2 parallel groups.

SETTING

Specialist centers in 2 university hospitals.

PATIENTS: Patients, 18-70 years, with acute vestibular neuritis confirmed by videonystagmography.

INTERVENTION: Standard care was 10 days of prednisolone, general information, and counseling given to all patients. In addition to standard care, the intervention group received supervised exercise therapy (vestibular rehabilitation). Vestibular rehabilitation was given in a group format, individually tailored, and supported by home exercises.

MAIN OUTCOME MEASURE: Perceived dizziness during head motion. Secondary outcomes were walking speed, standing balance, Hospital Anxiety and Depression Scale (HADS), Vertigo Symptom Scale, Visual Analog Scales (VASs), Dizziness Handicap Inventory (DHI), The University of California Los Angeles Dizziness Questionnaire.

RESULTS

Sixty-five patients were included, 27 participated in the vestibular rehabilitation group. There was a statistically significant difference in favor of the vestibular rehabilitation group in overall perceived dizziness at 3 (p = 0.007) and 12 months (p = 0.001). No statistically significant differences were found in standing balance and walking speed. Results from self-report measures showed a statistically significant difference at 12 months in HADS (p = 0.039), DHI (p = 0.049) and VAS-C (p = 0.012).

CONCLUSION

A vestibular rehabilitation program started early after confirmed vestibular neuritis diagnosis in addition to standard care reduces the perception of dizziness and improves functions of daily life more effectively than standard care alone.
