量化使用机械和微处理器控制的假体膝关节的经股截肢者的运动和自由生活体力活动的能量消耗的能量效率。重复测量设计以评估比较的功能结果。运动生理学实验室和社区自由生活环境。研究对象(N=15；男性12例，女性3例；年龄42±9岁；范围26-57岁)。研究参与者是机械假体的长期使用者(截肢者年龄为20±10岁；范围为3-36岁)。他们安装了微处理器控制的膝关节假体，并在复测之前允许适应(平均18±8wk)。获得了能源效率和每日总能量消耗的客观测量结果。使用假体评估问卷收集参与者的主观反馈。在配戴微处理器控制的假体膝关节后，受试者在参与者的自由生活环境中显示出与体力活动相关的能量消耗水平显著增加(P=0.04)。步行的能量效率无显著差异(P=.34)。当使用微处理器控制的膝盖时，受试者对日常生活的满意度增加(P=0.02)。使用微处理器控制的膝盖行走的人显著增加了他们在实验室以外的日常生活中的体力活动，并表达了更高的生活质量。
To quantify the energy efficiency of locomotion and free-living physical activity energy expenditure of transfemoral amputees using a mechanical and microprocessor-controlled prosthetic knee. Repeated-measures design to evaluate comparative functional outcomes. Exercise physiology laboratory and community free-living environment. Subjects (N=15; 12 men, 3 women; age, 42±9y; range, 26 –57y) with transfemoral amputation. Research participants were long-term users of a mechanical prosthesis (20±10y as an amputee; range, 3–36y). They were fitted with a microprocessor-controlled knee prosthesis and allowed to acclimate (mean time, 18±8wk) before being retested. Objective measurements of energy efficiency and total daily energy expenditure were obtained. The Prosthetic Evaluation Questionnaire was used to gather subjective feedback from the participants. Subjects demonstrated significantly increased physical activity–related energy expenditure levels in the participant’s free-living environment (P=.04) after wearing the microprocessor-controlled prosthetic knee joint. There was no significant difference in the energy efficiency of walking (P=.34). When using the microprocessor-controlled knee, the subjects expressed increased satisfaction in their daily lives (P=.02). People ambulating with a microprocessor-controlled knee significantly increased their physical activity during daily life, outside the laboratory setting, and expressed an increased quality of life.
