March 27, 2026 updated by: Brooke Klatt, University of Pittsburgh

Impairments and Personal Factors Associated With Activity and Participation in Vestibular Rehabilitation

This study will examine whether impairments and personal factors are associated with activity and participation in people with vestibulopathy. Data collection will occur prior to starting vestibular rehabilitation and after completing vestibular rehabilitation.

Detailed Description

Adults aged 18-years and older with symptomatic complaints of dizziness and/or imbalance and a medical diagnosis of unilateral vestibular hypofunction will be recruited at the time of their entry into vestibular rehabilitation. The investigators will analyze what factors (impairments and personal factors) are related to activity and participation in people with vestibular disorders and see if change in activity and participation is related to recovery from vestibulopathy.
