生物力学分析的工作和权力模式涉及步态提供洞察步态缺陷的性质，并提出改进的方法。本研究的目的是描述偏瘫患者的两个肢体在步态过程中的功和功率特性，并确定与自主选择的步行速度有关的功和功率变量。采用二维电影摄影和测力板数据，在链接段模型中研究了30名年龄在47岁至79岁之间的步行成年人的步态。大约40%的行走所需的正功是由患侧的肌肉完成的。主要贡献者是踝跖屈肌、髋屈肌和髋伸肌。结果表明，肢体之间的相互依赖性和同一肢体的肌肉群之间的需要进一步的研究。
Biomechanical analysis of the work and power patterns involved in gait provides insight into the nature of gait deficits and suggests methods for improvement. The purpose of this study was to describe the work and power characteristics during gait for both limbs of hemiplegic patients, and to determine the work and power variables related to self-selected speeds of walking. The gait of 30 ambulatory adults between the ages of 47 and 79 years was studied using two-dimensional cinematography and force-plate data in a link-segment model. About 40% of the positive work required for walking was performed by the muscles of the affected side. Major contributors were the ankle plantar flexors, hip flexors, and hip extensors. The results suggest interdependence between the limbs and between muscle groups of the same limb; a need for further research is indicated.
