目的：评价机械和微处理器假肢膝关节控制技术在功能、性能和偏好方面的差异。设计：A-B-A-B反转设计。环境：家庭、社区和实验室环境。参与者：21例单侧经股截肢者。干预：机械控制假膝与微处理器控制假膝（Otto Bock C-Leg）。主要观察指标：楼梯评定、爬坡评定和时间、障碍赛时间、分散注意任务准确度和时间、截肢者活动预测评分、台阶活动、假肢评估问卷评分、医疗结果研究36项简短健康调查评分、自我报告绊倒和跌倒的频率、自我报告行走所需的注意力。结果：楼梯下降得分、下山时间和山声侧步长差异有统计学意义(P
Objective: To evaluate differences in function, performance, and preference between mechanical and microprocessor prosthetic knee control technologies.Design: A-B-A-B reversal design.Setting: Home, community, and laboratory environments.Participants: Twenty-one unilateral, transfemoral amputees.Intervention: Mechanical control prosthetic knee versus microprocessor control prosthetic knee (Otto Bock C-Leg).Main Outcome Measures: Stair rating, hill rating and time, obstacle course time, divided attention task accuracy and time, Amputee Mobility Predictor score, step activity, Prosthesis Evaluation Questionnaire score, Medical Outcomes Study 36-Item Short-Form Health Survey score, self-reported frequency of stumbles and falls, and self-reported concentration required for ambulation.Results: Stair descent score, hill descent time, and hill sound-side step length showed significant (P
