[Purpose] This study investigated the effects of spring-loaded crutches on gastrocnemius muscle activity and upper body displacement in the sagittal plane during gait. [Subjects and Methods] The study involved 12 healthy males. All subjects performed crutch gait by using spring-loaded crutches and axillary crutches. During this gait, the gastrocnemius muscle activity was measured using a wireless electromyography system, and upward displacement of the body was measured using a three-dimensional motion analysis system. [Results] The gastrocnemius activity was significantly lower but upward displacement of the body was significantly greater with the spring-loaded crutches than with axillary crutches. [Conclusion] Spring-loaded crutches allow efficient crutch gait and involve less effort from the gastrocnemius muscle.
[目的] 本研究调查了弹簧加载拐杖在步态过程中对腓肠肌活动及矢状面内上身位移的影响。[对象与方法] 该研究纳入了12名健康男性。所有受试者分别使用弹簧加载拐杖和腋拐进行拄拐步态测试。在此步态过程中，使用无线肌电图系统测量腓肠肌活动，并使用三维运动分析系统测量身体的向上位移。[结果] 与腋拐相比，使用弹簧加载拐杖时腓肠肌活动显著降低，但身体向上位移显著增大。[结论] 弹簧加载拐杖能实现高效的拄拐步态，且腓肠肌用力较小。
