A questionnaire survey of 22 selected transfemoral amputees who were switched from pneumatic swing phase control knee joints (PSPC) to microprocessor controlled intelligent knee joints (IP) is presented. On overall rating all respondents considered the IP to be an improvement or a great improvement compared to the PSPC and none decided to revert back or wished to use their previous PSPC prosthesis on a regular basis. However the IP was not rated to be superior in every area of the questionnaire. Walking at different speeds, walking further, reduction of energy consumption were the main areas where subjective improvements were perceived by the amputees themselves. It is strongly believed that patients' own views should be an important and integral part of the evaluation of new prosthetic technology.
本文介绍了一项针对22名选定的经股截肢者的问卷调查，这些截肢者从气动摆动期控制膝关节（PSPC）转换为微处理器控制的智能膝关节（IP）。在总体评分中，所有受访者都认为与PSPC相比，IP有改进或有很大改进，没有人决定换回原来的产品，也没有人希望定期使用他们以前的PSPC假肢。然而，在问卷的各个方面，IP并没有被评为优于PSPC。截肢者自身认为，在不同速度行走、行走更远的距离以及降低能耗等主要方面有主观上的改善。人们坚信，患者自己的观点应该是新假肢技术评估的重要组成部分。
