A computer controlled wrist joint motion simulator has been developed that actively moves forearms from cadavers through cyclic planar flexion-extension motions, planar radial-ulnar deviation motions, and combined motions such as circumduction. Hybrid position-force feedback control algorithms are used to determine the wrist flexor and extensor tendon forces necessary to achieve the desired motions. The simulator was used in a series of 12 fresh cadaver forearms to produce both flexion-extension and radial-ulnar deviation motions and was found to cause repeatable, physiological movements. In these experiments, the extensor tendon forces were greater than those of the flexors, typically by a factor of two.
已开发出一种计算机控制的腕关节运动模拟器，该模拟器能使尸体的前臂通过周期性的平面屈伸运动、平面桡尺偏斜运动以及诸如环转等复合运动进行主动移动。采用混合位置-力反馈控制算法来确定实现所需运动所需的腕屈肌和伸肌腱力。该模拟器用于对12只新鲜尸体前臂进行一系列实验，以产生屈伸和桡尺偏斜运动，结果发现能引起可重复的生理性运动。在这些实验中，伸肌腱力大于屈肌腱力，通常是屈肌腱力的两倍。
