The calculation of net ankle, knee, and hip joint reaction forces is an often applied procedure in the analysis of gait. Except for very few studies, joint reaction forces have not been measured in other joints such as the fingers, wrist, elbow, shoulder and toes. In this study the joint reaction forces between the metatarsal head and the proximal phalanx and the metatarsal head and the sesamoids are calculated for the push off phase during gait. The results of ten normal elderly subjects show that the maximum resultant loads of the two articulations lie close to the longitudinal axis of the metatarsal. The knowledge of the magnitude and direction of the joint reaction forces of a normal elderly population will be essential for the design of an optimal fixation of an artificial anatomical first MTP joint.
在步态分析中，计算踝关节、膝关节和髋关节的净关节反应力是一种常用的方法。除了极少数研究外，尚未对手指、手腕、肘部、肩部和脚趾等其他关节的关节反应力进行测量。在本研究中，计算了步态蹬离阶段跖骨头与近节趾骨以及跖骨头与籽骨之间的关节反应力。十名正常老年受试者的结果表明，两个关节的最大合力载荷靠近跖骨的纵轴。了解正常老年人群关节反应力的大小和方向对于设计人工解剖学第一跖趾关节的最佳固定至关重要。
