在截肢过程中，不好的悬吊会增加残肢在接受腔内的滑动。本文的主要目的是评估步态期间假体内衬-接受腔界面的活塞运动，并评估患者对两种不同内衬的满意度。为10名经胫骨截肢的受试者分别制作了两个带有密封和锁定内衬的假体。采用Vicon运动系统测量步态中的活塞运动。还要求受试者完成假体评价问卷。结果显示，步态期间使用锁定内衬的关节窝内活塞运动高于使用密封内衬的关节窝内活塞运动（p <0.05）。锁定内衬的总体满意度更高（p <0.05），因为患者可以相对轻松地佩戴和拆卸该器械。因此，活塞运动可能不是决定患者对假体总体满意度的主要因素，其他因素也可能有助于假体的舒适度和满意度。本文还验证了Vicon运动系统测量步态活塞运动的可行性。
Poor suspension increases slippage of the residual limb inside the socket during ambulation. The main purpose of this article is to evaluate the pistoning at the prosthetic linersocket interface during gait and assess patients' satisfaction with two different liners. Two prostheses with seal-in and locking liners were fabricated for each of the 10 subjects with transtibial amputation. The Vicon motion system was used to measure the pistoning during gait. The subjects were also asked to complete a Prosthesis Evaluation Questionnaire. The results revealed higher pistoning inside the socket during gait with the locking liner than with the seal-in liner (p < 0.05). The overall satisfaction with the locking liner was higher (p < 0.05) because of the relative ease with which the patients could don and doff the device. As such, pistoning may not be the main factor that determines patients' overall satisfaction with the prosthesis and other factors may also contribute to comfort and satisfaction with prostheses. The article also verifies the feasibility of the Vicon motion system for measuring pistoning during gait.
