Table 1.
Reductions in the peak knee adduction moment (KAM), knee flexion moment (KFMabs), and estimated medical contact force when all subjects walked at their subject-specific FPA. When walking at this FPA, 18 of 20 subjects significantly reduced their KAM peak and 13 significantly reduced their estimated medial contact force compared to baseline. For subjects 18–20, all reported values are for the second peak of each parameter. (bold: p < .05).
