The purpose of this study was to objectively evaluate the fit of sockets for trans-tibial stumps in order to establish a guideline for use in the automated production of prosthetic sockets. Subjects were 24 trans-tibial amputees. Using a CAD/CAM system, 11 parameters regarding the 3D shape of the stumps and the sockets were objectively evaluated. A correlation was found between the activity level and the upper and lower volumes of the socket, and between the cause of amputation and the upper volume of the socket. It was considered desirable to make the lower part of the socket looser for patients with lower activity levels, to make the upper part tighter for patients with higher activity levels, and to make the upper part looser for amputation patients with peripheral circulatory diseases.
本研究的目的是客观评估经胫截肢残肢接受腔的适配性，以便为假肢接受腔的自动化生产制定使用指南。受试者为24名经胫截肢者。使用计算机辅助设计/计算机辅助制造（CAD/CAM）系统，对与残肢和接受腔三维形状相关的11个参数进行了客观评估。发现活动水平与接受腔的上下容积之间、截肢原因与接受腔的上容积之间存在相关性。对于活动水平较低的患者，使接受腔下部更宽松；对于活动水平较高的患者，使接受腔上部更紧实；对于患有外周循环疾病的截肢患者，使接受腔上部更宽松，这些被认为是可取的。
