To make a comparative study of energy expenditure and walking speeds between able-bodied people and young Intelligent Prosthesis (IP) users and to demonstrate the effect of IP on the walking ability of young amputees.
The test subjects were eight young traumatic transfemoral amputees. Fourteen able-bodied persons served as controls. All amputees used an IP, and they had all undergone a prosthetic rehabilitation program for 8 wk. IP users, who had completed the rehabilitation program, were instructed to walk at speeds of 30, 50, 70, 90, and 110 m/min. Measurements of energy expenditure while walking were taken. The most metabolically efficient waking speed was also determined.
On average, the IP users experienced an oxygen uptake that was 24.1% and 24.2% higher than those for the controls at speeds of 70 and 90 m/min, respectively. It was also determined that the most metabolically efficient walking speed for the IP users was the same as for the controls.
This study showed that young IP users who undergo an adequate prosthetic rehabilitation program can achieve remarkably improved walking performance. Young IP users could walk at the normal speeds of able-bodied people, with only around a 24% increase in energy expenditure.
对健全人与年轻智能假肢（IP）使用者之间的能量消耗和步行速度进行比较研究，并证明IP对年轻截肢者步行能力的影响。
测试对象为8名年轻创伤性经股骨截肢者。14名健全人作为对照。所有截肢者均使用IP，且都接受了为期8周的假肢康复计划。指示完成康复计划的IP使用者以30、50、70、90和110米/分钟的速度行走。同时测量行走时的能量消耗。还确定了代谢效率最高的步行速度。
平均而言，在70米/分钟和90米/分钟的速度下，IP使用者的摄氧量分别比对照组高24.1%和24.2%。还确定IP使用者代谢效率最高的步行速度与对照组相同。
本研究表明，接受充分假肢康复计划的年轻IP使用者可以显著提高步行性能。年轻IP使用者能够以健全人的正常速度行走，能量消耗仅增加约24%。
