Notes: Performance of patients who were able to complete mCTSIB and MCT compared to a normative database of control subjects. The unit of measure for mCTSIB is sway velocity of the center of gravity, measured in degrees/second. MCT measures are latency of response (milliseconds), either right or left, and strength = amplitude of the strength response (unitless), either right or left. Significant p values are bolded. Two 70-year-old participants were excluded from the analysis due to a lack of normative data for comparison.
