AbstractBackground study 1: Individuals with vestibular disorders usually complain of dizziness and visual vertigo in visually complex environments. Habituation exercises using visually provocative stimuli have been shown to be useful during vestibular rehabilitation. Virtual reality based therapy (VRBT) is an emerging technology that can be used in vestibular rehabilitation to provide visual habituation exercises for individuals with vestibular disorders. The purpose of the study was to explore the use of VRBT in the treatment of individuals with vestibular disorders and to examine the difference in self report and performance measures between VRBT and customized physical therapy (PT). Methods: Forty subjects with vestibular disorders participated in the study; subjects were assigned into two groups (VRBT or PT). Both groups had six treatment sessions for six weeks, and were assessed using self-report and performance measures. Results: Both groups improved similarly in most of self-report and performance measures and maintained improvements for six months after the intervention ended. Background study 2: Falling is a risk factor associated with vestibular disorders that can impact quality of life and reduce participation in daily life. Falling can be caused by a decline in function of sensory inputs associated with aging. Measuring sensory control during standing may help to investigate age and vestibular disease effects on balance. The Balance Rehabilitation Unit (BRU) utilizes high technology in balance assessment. The psychometric properties of the BRU including the reliability and validity have not been studied. The purpose of study 2 was to examine the reliability and validity of the BRU in the assessment of people with and without vestibular disorders. Methods: Ninety subjects (30 young healthy, 30 older healthy over 60 years of age, 30 individuals with vestibular disorders) participated in this study. Results: The BRU provided a reliable and valid measure for measuring the sensory contributions to postural control for healthy persons and people with vestibular disorders and was able to discriminate age and disease effect on balance.
