Development of a Mechanistic Hypothesis Linking Compensatory Biomechanics and Stepping Asymmetry during Gait of Transfemoral Amputees

Table 2

Gait parameters measured for controls () and two transfemoral amputees during slow, normal, and fast speed gait, and results of the single sample -test between amputee and sample of control subjects.
