The running ability of ten unilateral below-knee amputees was examined by analyzing the temporal and length characteristics of their running strides and the angular displacement patterns of their intact and prosthetic limbs. Six of the individuals tested were able to run and in several cases their locomotor patterns were similar to those of non-amputees. The running gait of three of the amputee runners, however, did contain one particular undesirable element namely an excessively straight residual knee during at least a portion of support on the prosthesis. Although several explanations could be postulated to account for this tendency, we believe that it could be eliminated with training and possible prosthetic modification. Results of the study, while attesting to the fact that many lower extremity amputees can run, also suggested directions in which research efforts can and are being focused to facilitate their running performance.
通过分析十名单侧膝下截肢者跑步步幅的时间和长度特征以及其健全肢体和假肢的角位移模式，对他们的跑步能力进行了检测。测试的十人中六人能够跑步，在某些情况下，他们的运动模式与非截肢者相似。然而，三名截肢跑步者的跑步步态确实包含一个特别不理想的因素，即在至少部分假肢支撑期，残肢膝关节过度伸直。虽然可以提出几种解释来说明这种倾向，但我们认为通过训练和可能的假肢改进可以消除这种情况。该研究结果在证明许多下肢截肢者能够跑步这一事实的同时，也指出了研究工作可以且正在集中精力以提高他们跑步表现的方向。
