The precision grip requires the control of the normal and tangential forces exerted by the fingers as well as the control of the rotational equilibrium of the grasped object. Prehension synergies involve the conjoint changes in finger forces and moments during multifinger gripping tasks. Some of these adjustments are dictated by mechanics, whereas others are the result of a choice by the performer.
精确抓握需要控制手指施加的法向力和切向力,以及控制被抓握物体的旋转平衡。抓握协同作用涉及多手指抓握任务中手指力和力矩的联合变化。其中一些调整由力学决定,而其他调整则是执行者选择的结果。
