Primary outcomePrimary: Change in Visual Acuity During Head Movement From Baseline to Discharge — 0.198; .296 LogMAR
Summary
The purpose of this study is to determine whether exercises relieve the symptoms of dizziness and imbalance in people with vestibular deficits and improves the ability to see clearly during head movements. We hypothesize that the performance of specific adaptation and substitution exercises will result in an improvement in visual acuity during head movements while those patients performing placebo exercises will show no improvement.

Eligibility Criteria
Inclusion Criteria
- Patient had to have either a unilateral vestibular or bilateral vestibular hypofunction defined as follows: Unilateral vestibular deficits were defined by a > 25% difference in slow phase eye velocity between right and left sides on either the caloric or rotary chair test. Bilateral vestibular deficits were defined included refixation saccades made in response to unpredictable head thrusts to the right and left, a gain < .1 on rotary chair step test and a peak slow phase eye movement of <5 degrees/sec during irrigation of each ear on bithermal water caloric testing
- Healthy subjects with normal vestibular function test results
- must be able to complete DVA test
Exclusion Criteria
- Patients with central lesions will be omitted from the study because vestibular adaptation or other compensatory mechanisms may be compromised and
- Patients with visual acuity when the head is stationary of 20/60 or worse.
- Patients on medication that suppress or facilitate vestibular function will not be excluded from the study but data will be analyzed to assess the effect of medication.
- Patient who do not understand the purpose of the study and what it involves
