This paper presents some basic biomechanical considerations that can form a basis for analysis of stance deviations. The floor reaction forces and their effects on the lower extremity are reviewed as a basis for understanding the pathomechanics of stance. Pathomechanics includes the unwanted motions that tend to be created by the floor reaction forces in the absence of critical muscle activity. Compensatory postures that a patient may assume to prevent these unwanted motions and compensatory postures that a patient may assume at one joint because of abnormal positioning at another joint are discussed. Finally, the influence of joint posture from one phase of gait to another is explained.
本文提出了一些基本的生物力学考量因素，这些因素可为分析站立偏差奠定基础。作为理解站立病理力学的基础，本文回顾了地面反作用力及其对下肢的影响。病理力学包括在缺乏关键肌肉活动时，地面反作用力往往会产生的不必要运动。文中讨论了患者可能采取的补偿性姿势，以防止这些不必要的运动，以及患者可能由于另一个关节的异常定位而在一个关节处采取的补偿性姿势。最后，解释了关节姿势在步态的一个阶段到另一个阶段的影响。
