Fig. 6. A graph showing the net angle change during stance at each joint as a
function of acceleration. Positive values represent net joint extension while
negative values represent net joint flexion. The results of linear regressions
showed significant correlations at all joints (hip:
r2=0.50, P<0.0001; knee:
r2=0.47, P<0.0001; ankle:
r2=0.51, P<0.0001; MP:
r2=0.19, P=0.017).
