Quite a few people sustaining a traumatic brain injury experience vestibular pathology requiring physical therapy for treatment. This study measured improvements in gait speed and weight shift for subjects receiving vestibular physical therapy using a Computer-Assisted Rehabilitation Environment (CAREN). A 6-session CAREN, 6-session traditional vestibular therapy group was compared with a 12-session CAREN only (0 traditional sessions) therapy group. These two groups were compared to each other and with data from healthy controls performing comparable tasks on the CAREN. Those participating in 12 CAREN sessions had greater improvements in gait speed (p = 0.014) and weight shift scores (p < 0.001) and exhibited similar values achieved by a healthy control population.
