OKS for Gait Instability

Optokinetic Stimulation for the Treatment of Gait Abnormalities

Specific aim: To determine whether optokinetic stimulation can improve gait abnormalities.

Hypothesis: Optokinetic stimulation stimulates the vestibular system and can improve vestibular induced gait disorders.

This is a pilot study designed to determine whether or not the optokinetic stimulation improves gait in patients with gait abnormalities, specifically vestibular induced gait disorders. The study population will consist of patients already receiving a gait assessment through the Brain Fit Club (BFC) at Beth Israel Deaconess Medical Center. This gait assessment involves walking and posture evaluations. Patients will complete a gait assessment as part of their normal BFC evaluation. Those who consent to participate in the study will then complete a gait assessment while receiving optokinetic stimulation. The investigators will compare baseline gait and postural control before and during OKS stimulation.

Inclusion criteria:

• Receiving a gait assessment through the BFC
• Ages 21-75

Exclusion criteria:

• Left hemiparesis
• Requires a cane or walker
• Documented evidence of falls or instability to the left
• Reduced vision
• Moderate or severe dementia
