本研究的目的是探讨本体感觉改变在预期性和代偿性姿势调整中的作用及其相互作用。9名健康成人暴露于双侧跟腱振动引起的完整或改变本体感觉的站立时肩位诱发的外部扰动。在两种情况下，视觉信息都发生了改变（眼睛睁开或闭上）。在APAs和CPAs的典型时间间隔内记录并量化8个躯干和腿部肌肉的电活动和压力中心（COP）位移。结果表明，当本体感觉信息在睁眼状态下被改变时，预期肌活动被延迟。此外，在睁眼和闭眼条件下，本体感觉信息的改变导致代偿肌活动的幅度较小，COP位移较小。该研究的结果提供了在本体感觉改变的情况下APAs和cpa之间相互作用的信息。
The purpose of the study was to investigate the role of altered proprioception on anticipatory (APAs) and compensatory (CPAs) postural adjustments and their interaction. Nine healthy adults were exposed to external perturbations induced at the shoulder level while standing with intact or altered proprioception induced by bilateral Achilles tendon vibration. Visual information was altered (eyes open or closed) in both the conditions. Electrical activity of the eight trunk and leg muscles and center of pressure (COP) displacements were recorded and quantified within the time intervals typical for APAs and CPAs. The results showed that when proprioceptive information was altered in eyes open conditions, anticipatory muscle activity was delayed. Moreover, altered proprioceptive information resulted in smaller magnitudes of compensatory muscle activity as well as smaller COP displacements after the perturbation in both eyes open and eyes closed conditions. The outcome of the study provides information on the interaction between APAs and CPAs in the presence of altered proprioception.
