Socket Pressure Distribution of the Uni-Lateral Trans-Femoral Amputee with a Suction Socket

흡착식 소켓을 착용한 일측 대퇴절단환자의 소켓내부압력분포

A study on static and dynamic socket pressure distributions on a trans-femoral amputee with a suction socket was performed in order to assess an optimal socket fitting and function. Even for the amputee's static neutral position, pressure concentrations were observed in the lateral, medial, and posterior planes of the socket. During free walking, a significant movement of pressure concentration areas was observed. Large socket pressure was observed in the lateral, medial-anterior and posterior walls during mid-stance or push-off period. Socket pressure measurement will be one of the good tool to determine the optimal socket-limb interface.
