Pilot Feasibility of App-supported Vestibular Rehabilitation

The primary goal of the study is to examine the feasibility of accompanying vestibular practice supported by a phone app for vestibular rehabilitation. Feasibility will be established using the following parameters: (1) the User Satisfaction Evaluation Questionnaire (USEQ) (2) a custom-made questionnaire to collect feedback from participants, and (3) compliance measurements derived from app usage. The secondary goal of the study is to examine the effect of practice supported by the app on balance and anxiety indices. These will be measured using the following parameters: (1) Instrumented Timed Up and Go Test (iTUG), (2) Dizziness Handicap Inventory (DHI), (3) State-Trait Anxiety Inventory (STAI). The third goal is to assess the correlation between balance function (iTUG) and anxiety (STAI). A randomized crossover pilot study will be conducted with 24 participants. During the study, each group will undergo two and a half weeks of conventional vestibular rehabilitation and two and a half weeks of app-supported vestibular rehabilitation. Measurement sessions will be conducted at three-time points: upon enrollment in the study (T0), after two and a half weeks (T1), and at the end of the study (T2).
