Fig. 6From: Can an insole for obese individuals maintain the arch of the foot against repeated hyper loading?Time-dependent change in flexibility and energy absorption. Time-dependent changes in flexibility (a) and energy absorption (b) in the normal, obese, and insole groups. Coordinate points represent mean change; bars represent 95% confidence intervals. Flexibility and energy absorption decrease significantly over time in the obese and insole groups (* P < 0.001 for both), but not in the normal group (P = 0.081)Back to article page
