基于卡伦康复系统探讨大腿截肢患者穿戴智能膝关节步态的对比研究

A Comparative Study on Gait of Thigh Amputees Wearing Intelligent Knee Joint Based on Caren Rehabilitation System

摘要: 目的：探讨单侧大腿截肢者穿戴假智能膝关节后的步态情况。方法：8例单侧大腿截肢穿戴假肢者为实验组，8名健康成年人为对照组，分别在卡伦系统上进行平整路面步行五分钟的测试。结果：实验组在穿戴智能膝关节与对照组相比在步速、步长、摆动期支撑时间、双支撑期时间和整个步态周期存在统计学的差异(P < 0.05)。跨步长与站立期与正常对照组无差异，没有统计学意义(P > 0.05)。结论：单侧大腿截肢患者穿戴智能膝关节与正常人的行走功能存在差异；大腿截肢患者穿戴智能膝关节对步行能力产生影响。

Abstract: Purpose: To investigate the walking characteristics of unilateral leg amputees wearing artificial intelligent knee joint. Methods: Eight patients with unilateral thigh amputation and prosthetic limbs were divided into experimental group and eight healthy adults as control group. The five-minute walking test was performed on the Caren system. Results: There were statistical dif-ferences between the experimental group and the control group in walking speed, step length, support time during swing period, double support time and whole gait cycle (P < 0.05). There was no significant difference in step length and standing period between the two groups (P > 0.05). Conclusion: There are differences in walking function between unilateral thigh amputation wearing intelligent knee joint and normal people. Wearing intelligent knee joints in thigh amputees has an impact on walking ability.
