在100米以上的短跑比赛中，运动员将有50%以上的时间是在曲线上跑。在科学文献中找不到关于假肢曲线短跑的地面反作用力或关节动力学的数据。本研究的目的是使用三维运动捕捉系统和四个测力板分析GRF和作用在假体叶片上的力矩。一位国际最高水平的左侧单侧截肢运动员（膝关节切除术），顺时针和逆时针跑了30米直线和曲线。GRF显示曲线和直线运行之间的差异。结果表明，与直线运行相比，曲线运行时施加到假体叶片上的载荷不同。这项研究提供了一个内部的动力学截肢曲线运行，并可能会影响未来的假肢一代的建设和设计，以及性能诊断。
In athletics sprinting longer than 100 m, athletes will run more than 50% in a curve. No data on ground reaction forces or joint kinetics of prosthetic curve sprinting can be found in the scientific literature. The purpose of this study was to analyze GRFs and moments acting on the prosthesis’ blade using a 3D motion capture system and four force plates. A left sided unilateral amputee athlete (knee exarticulation) of highest international level, ran 30 m straight and curved clockwise and counter clockwise. GRFs show differences between curve and straight running. Results show different loading applied to the blade of a prosthesis when curve running in comparison with straight running. The study gives an inside into the kinetics of amputee curve running and might affect the construction and design of future prosthesis generations as well as performance diagnostics.
