Resumo(s)
The purpose of this study was to compare the gait waveforms of the sagittal (KnSAG) and frontal (KnFRT) knee moments between both limbs of TF amputees with able-bodied subjects using PCA. the self-selected speed gait form 14 TF amputees and 20 able-bodied individuals was analyzed. The KnSAG and KnFRT of able-bodied participants, amputated limb and sound limb were calculated using the inverse dynamics approach. PCA was performed in moment waveforms. Considering KnSAG, both TF's lower limbs presented statistical differences compared to the able-bodied participants, while for KnFRT, only the sound limb showed statistical differences compared to the able-bodied subjects. PCA analysis seems to be a powerful tool to analyze gait parameters because it reduces the number of variables necessary to represent the whole gait waveform and it showed to be sensible to identify alterations in knee moment bahaviour.
