Objective To describe and compare the plantar pressures, temporal foot roll‐over, ground reaction forces (GRFs) between both limbs of subjects with unilateral transfemoral amputation those able‐bodied participants during walking. We also verify relevance a force plate pressure to discriminate changes in gait parameters limb loss. Design Cross‐sectional study. Setting Biomechanics laboratory. Subjects A total 14 21 participants. Methods used assess biomechanical while were walking at their self‐selected speed. Main Outcome Measurements measured peaks 6 regions instant occurrence (temporal roll‐over); GRF impulses anterior‐posterior (braking propulsive phases), medial‐lateral, vertical (load acceptance thrust phases) components. Results The thrust, braking, peaks, braking impulses, statistically significantly lower amputated than sound ( P < .05) .05). In limb, we observed higher lateral rearfoot medial midfoot, values forefoot compared other groups roll‐over showed significant differences among Conclusions GRFs an asymmetric pattern, different as able determine suggesting that analyses are useful tools for assessment individuals amputation. Because convenience plates, use clinical context prosthetic management appears relevant guide rehabilitation
