The effects of age-related sensorimotor and central processing deficits on postural control are reviewed, and the paucity of knowledge about proprioceptive changes with age is noted. A model of processing stages in the production of responses to postural instability is outlined. Even slight response slowing produces disproportionate increases in clinically slow responses. Many aspects of postural responses are "cognitively penetrable". Research on falls should examine learned as well as automated behaviors.
本文综述了与年龄相关的感觉运动和中枢处理缺陷对姿势控制的影响，并指出了关于本体感觉随年龄变化的知识匮乏。概述了对姿势不稳定做出反应过程中的处理阶段模型。即使是轻微的反应减慢也会使临床上的缓慢反应出现不成比例的增加。姿势反应的许多方面是“认知可穿透的”。对跌倒的研究应同时考察习得行为和自动行为。
