Functional arm reaching involves multilinked joints: shoulder, elbow, and wrist. We propose that induced position analysis is a useful analytical tool for multijoint coordination of arm reaching. This method was used to compute the contributions of the net joint moment to the hand position when reaching forward. We describe the method and give examples of validating this model with motion capture data. The shoulder and elbow were prime movers of the arm: both acted together with an "overshoot" and "undershoot" pattern respectively to move the hand forward into the final position.
肩部、肘部和腕部。我们提出，诱导位置分析是用于手臂伸展多关节协调的一种有用分析工具。该方法用于计算向前伸展时净关节力矩对手部位置的贡献。我们描述了该方法，并给出了用运动捕捉数据验证该模型的示例。肩部和肘部是手臂的主要推动者：两者分别以“过冲”和“欠冲”模式共同作用，将手部向前移动到最终位置。
