背景：胫骨截肢者在日常活动中会遇到楼梯和台阶。残肢/关节窝之间的过大压力可能会降低经胫义肢使用者在上下楼梯时的行走能力。本研究的目的是评估Dermo（穿梭锁）和Seal-In X5（假体阀）界面系统在楼梯上升和下降过程中的界面压力，并确定其对用户的满意度效果。方法：对10例单侧经胫截肢患者进行研究。用f插座传感器（9811E）记录楼梯上升和下降时的界面压力。每位参与者都填写了一份关于使用这两个界面系统的满意度和遇到的问题的问卷。结果：在楼梯上升过程中，Dermo界面系统在前、后和内侧区域的平均峰值压力（kPa）明显低于al- in X5界面系统（分别为63.14 vs. 80.14、63.14 vs. 90.44、49.21 vs. 66.04）和下降过程中（67.11 vs. 80.41、64.12 vs. 8824、47.33 vs. 65.11）。两种接口系统在满意度和遇到的问题方面存在显著的统计学差异（P < 0.05）。解释：与Seal-In X5接口系统相比，Dermo接口系统在楼梯移动过程中对假肢窝的压力更小。定性调查还表明，假体使用者遇到的问题较少，对Dermo接口系统的满意度也有所提高。(C) 2013年作者。Elsevier Ltd.出版。版权所有。
Background: Transtibial amputees encounter stairs and steps during their daily activities. The excessive pressure between residual limb/socket may reduce the walking capability of transtibial prosthetic users during ascent and descent on stairs. The purposes of the research were to evaluate the interface pressure between Dermo (shuttle lock) and Seal-In X5 (prosthetic valve) interface systems during stair ascent and descent, and to determine their satisfaction effects on users.Methods: Ten amputees with unilateral transtibial amputation participated in the study. Interface pressure was recorded with F-socket transducer (9811E) during stair ascent and descent at self-selected speed. Each participant filled in a questionnaire about satisfaction and problems encountered with the use of the two interface systems.Findings: The resultant mean peak pressure (kPa) was significantly lower for the Dermo interface system compared to that of the Seal-In X5 interface system at the anterior, posterior and medial regions during stair ascent (63.14 vs. 80.14, 63.14 vs. 90.44, 49.21 vs. 66.04, respectively) and descent (67.11 vs. 80.41, 64.12 vs. 8824, 47.33 vs. 65.11, respectively). Significant statistical difference existed between the two interface systems in terms of satisfaction and problems encountered (P < 0.05).Interpretation: The Dermo interface system caused less pressure within the prosthetic socket compared to the Seal-In X5 interface system during stair negotiation. The qualitative survey also showed that the prosthesis users experienced fewer problems and increased satisfaction with the Dermo interface system. (C) 2013 The Authors. Published by Elsevier Ltd.
