The swing phase of hip disarticulation amputee walking: An analysis of walking constraints and methodological implications for gait analysis.
Hip-Disarticulation amputee walking was studied and methods used for the analysis of gait were examined. The hypothesis was tested that a Hip-Disarticulation amputee's walking velocity is limited by the inability to control the swing of the prosthesis. A technique based on the systematic analysis of constraints was proposed and employed in the study.;One subject was investigated and an inverse dynamics procedure was performed to analyze the forces acting upon the prosthesis during the swing phase. The results of the experiments indicate that the amputee did not actively promote the swing of the prosthetic limb. The analysis of constraints showed that the ability of the amputee to control the prosthesis during the swing phase was severely limited.;The systematic analysis of constraints is a powerful technique for examination of gait control methods. However, numerical analysis issues make its application difficult.
