The VR group will perform vestibular exercises plus balance and gait exercises. The CON group will perform saccadic eye movements without targets against a blank wall, as well as balance and gait exercises. The balance and gait exercises for each group will be based on identified impairments and functional limitations, as is the standard of care in physical therapy. All subjects within a group will follow the same exercise progression for the vestibular or eye movement exercises. Subjects will be seen in the clinic on a weekly basis to review and modify the exercises according to a standard protocol and to reinforce compliance.
