Table 2.

Significant differences found in all study measures between subjects who did not require an orthotic and/or assistive device compared to the subjects who required an orthotic and/or assistive device. Measures include: The Activities-specific Balance Confidence Scale = ABC score, and the Timed up and Go (TUG). CV = Coefficient of Variability.
