本研究的目的是调查三维下肢关节力矩的差异，四肢和速度的影响，这些差异在个人与下肢截肢使用运行特定prosthes.DesignEight个人与单侧transtibial截肢和8个对照组没有截肢跑在地上三个恒定的速度（2.5，3.0，和3.5米/秒）。A 2× 2× 3（组×腿×速度）重复测量方差分析与Bonferroni调整确定统计学显著性。结果假肢产生显著更大的峰值踝跖屈力矩和更小的峰值踝内翻、膝站立伸展、膝摆动屈曲、膝内旋、髋站立屈曲、髋摆动屈曲、髋摆动伸展、髋外翻，和髋关节外旋力矩。完整的肢体有更大的峰值髋关节外旋力矩比控制肢体，但所有其他峰值力矩是相似的这些肢体之间。增加峰值髋关节的立场和膝关节摆动屈曲力矩与速度在完整的肢体比在prosthetic limbs.Conclusionindividuals依靠完整的肢体比假肢运行在一个特定的速度时，穿着运行特定的假肢，但完整的关节没有超载相对于控制肢体。
ObjectiveThe objective of this study was to investigate three-dimensional lower extremity joint moment differences between limbs and speed influences on these differences in individuals with lower extremity amputations using running-specific prostheses.DesignEight individuals with unilateral transtibial amputations and 8 control subjects with no amputations ran overground at three constant velocities (2.5, 3.0, and 3.5 m/sec). A 2× 2× 3 (group× leg× speed) repeated-measures analysis of variance with Bonferroni adjustments determined statistical significance.ResultsThe prosthetic limb generated significantly greater peak ankle plantarflexion moments and smaller peak ankle varus, knee stance extension, knee swing flexion, knee internal rotation, hip stance flexion, hip swing flexion, hip swing extension, hip valgus, and hip external rotation moments than the intact limb did. The intact limb had greater peak hip external rotation moments than control limbs did, but all other peak moments were similar between these limbs. Increases in peak hip stance and knee swing flexion moments associated with speed were greater in the intact limb than in the prosthetic limb.ConclusionIndividuals with amputation relied on the intact limb more than the prosthetic limb to run at a particular speed when wearing running-specific prostheses, but the intact joints were not overloaded relative to the control limbs.
