The etiology of epicondylalgia lateralis humeri (tennis elbow) is not fully understood. A biomechanical model is introduced for those types of epicondylalgia where damage at the origin of the wrist and finger extensor muscles is caused by overloading. It shows that grasping and pinching always cause a flexing moment at the wrist joint. To avoid flexion of the joint, there must be equilibrium of moments, which is attained by activity of the extensor muscles. Simultaneous measurements of force and electromyograms support the biomechanical model.
肱骨外上髁炎（网球肘）的病因尚未完全明确。本文针对因过载导致腕部和手指伸肌起点处损伤的那类肱骨外上髁炎引入了一种生物力学模型。该模型表明，抓握和捏东西时总会在腕关节处产生一个屈曲力矩。为避免关节屈曲，必须实现力矩平衡，这可通过伸肌的活动来达成。对力和肌电图的同步测量结果支持了该生物力学模型。
