Values are means ± SD. Negative values denote joint flexion and ankle dorsiflexion. Hip ROM, difference between most extended and flexed positions of the hip joint in the swing phase; Hip AP, average hip joint angular position in the stance phase; Maximal KF, maximal knee flexion in early stance phase; Knee AP, average knee joint angular position in the stance phase; Ankle AP, average ankle angular position in the stance phase. Italics denote P < 0.05.

^*P < 0.05, different relative to baseline.
