Abstract(s)

The purpose of this study was to compare the gait waveforms of the ankle, knee and hip in sagital plane kinematic variables between both limbs of transfemoral (TF) amputees and able-bodied subjects using principal component analysis (PCA). Fourteen TF amputees and 20 able-bodied subjects were enrolled in the study. The ankle, knee and hip sagittal plane kinematics were recorded for the able-bodied participants, for the amputed limb and sound limb during self-selected speed gait. The results showed that both TF's lower limbs presented statistical differences in all sudied joints when compared to the able-bodied participants, in different phases in the gait cycle. Also PCA analysis seems to be a powerful tool to descriminate gait parameters considering the whole waveform of the variables involved.
