Biodex (Biodex Medical Systems, Inc) balance outcomes at A, baseline, B, 10 weeks, and C, 1 year. The distance from the center of the body (COB) was also calculated using the standardized zones A through D defined in the system, where each zone represents an increment of 5° in tilt of the platform, from 5° in zone A to a maximum 20° in zone D. The percentage of the COB trace in each zone at each time is shown: A, 90% for zone A, 10% for zone B, and 0% for zones C and D; B and C, 100% for zone A and 0% for zones B through D.
