背景：残肢与义肢窝之间的界面压力对截肢者的满意度和舒适度有重要影响。衬垫提供了一个舒适的界面，增加了一个软垫之间的残肢和插座。Dermo和Seal-In X5内衬是两种新的界面系统，由于它们的相对婴儿期，人们对它们对患者满意度的影响知之甚少。本研究的目的是比较这两种内衬的界面压力及其对患者满意度的影响。方法：对9例单侧经胫截肢患者进行研究。为每个截肢者制作了两个假肢，一个带有Seal-In衬垫，一个带有Dermo衬垫。在平地上行走时测量前、后、中、外侧区域的界面压力。每位受试者填写一份假体评估问卷（PEQ），以了解对这两个衬垫的满意度。结果：Seal-In衬套的平均峰值压力在窝前区高34.0%，在窝后区高24.0%，在窝内侧区高7.0% （P=0.008）。P = 0.046。P=0.025)。在两个衬垫之间的平均峰值压力在侧面区域没有显著差异。此外，在满意度和问题上，两组之间存在显著差异（P < 0.05）。解释：使用Dermo衬垫后，窝与残肢之间的界面压力更小。结果表明，与Seal-In衬管相比，Dermo衬管在套管内提供了更高的舒适度。(C) 2012 Elsevier Ltd.版权所有。
Background: The interface pressure between the residual limb and prosthetic socket has a significant effect on an amputee's satisfaction and comfort. Liners provide a comfortable interface by adding a soft cushion between the residual limb and the socket. The Dermo and the Seal-In X5 liner are two new interface systems and, due to their relative infancy, very little are known about their effect on patient satisfaction. The aim of this study was to compare the interface pressure with these two liners and their effect on patient satisfaction.Methods: Nine unilateral transtibial amputees participated in the study. Two prostheses were fabricated for each amputee, one with the Seal-In liner and one with the Dermo liner. Interface pressure was measured at the anterior, posterior, medial and lateral regions during walking on the level ground. Each subject filled in a Prosthetic Evaluation Questionnaire (PEQ) regarding the satisfaction with the two liners.Findings: The mean peak pressures with the Seal-In liner was 34.0% higher at the anterior, 24.0% higher at the posterior and 7.0% higher at the medial regions of the socket (P=0.008. P=0.046. P=0.025) than it was with the Dermo Liner. There were no significant differences in the mean peak pressures between the two liners at the lateral regions. In addition, significant difference was found between the two liners both for satisfaction and problems (P < 0.05).Interpretation:There was less interface pressure between the socket and the residual limb with the Dermo liner. The results indicated that the Dermo liner provides more comfort in the socket than the Seal-In liner. (C) 2012 Elsevier Ltd. All rights reserved.
