Movement is performed against a background of subtle postural adjustments that counteract destabilizing forces imposed by the movement. Despite the importance of these postural adjustments to the safe and efficient performance of movement, little is known about the properties of these postural accompaniments. The purpose of this article is twofold. First, it provides a review of properties of postural adjustments that accompany a variety of limb and trunk movements. Second, a schema for the coordination of posture and movement is proposed. This schema suggests that a central nervous system model of body dynamics is essential to anticipatory control of posture during movement.
运动是在微妙的姿势调整背景下进行的，这些姿势调整可抵消运动所施加的不稳定力量。尽管这些姿势调整对于运动的安全和高效执行很重要，但对于这些姿势伴随动作的特性却知之甚少。本文的目的有两个。首先，它回顾了伴随各种肢体和躯干运动的姿势调整的特性。其次，提出了一个姿势与运动协调的模式。该模式表明，身体动力学的中枢神经系统模型对于运动过程中姿势的预期控制至关重要。
