本研究的目的是调查不同的支持表面的前馈和反馈成分的姿势控制的效果。9名健康受试者暴露于施加于肩部的外部扰动，同时站在刚性平台、泡沫和摇摆板上，眼睛睁着或闭着。在典型的前馈和反馈姿势调整的时间范围内，记录和分析了9个躯干和腿部肌肉的电活动和压力中心的位移。前馈控制的姿态的特点是早期激活的前肌肉时，受试者站在泡沫相比，摇摆板或坚实的表面。此外，当使用泡沫时，前馈肌肉活动的幅度最大。在反馈控制过程中，无论表面的性质如何，前部肌肉都先于后部肌肉被激活。此外，最大的肌肉活动时，看到的支持表面是泡沫。当受试者站在刚性表面上时，CoP位移最大。改变支撑表面影响姿势控制的前馈和反馈分量。在规划旨在改善平衡的康复干预措施时应考虑到这一信息。
The aim of the study was to investigate the effect of different support surfaces on feedforward and feedback components of postural control. Nine healthy subjects were exposed to external perturbations applied to their shoulders while standing on a rigid platform, foam, and wobble board with eyes open or closed. Electrical activity of nine trunk and leg muscles and displacements of the center of pressure were recorded and analyzed during the time frames typical of feedforward and feedback postural adjustments. Feedforward control of posture was characterized by earlier activation of anterior muscles when the subjects stood on foam compared to a wobble board or a firm surface. In addition, the magnitude of feedforward muscle activity was the largest when the foam was used. During the feedback control, anterior muscles were activated prior to posterior muscles irrespective of the nature of surface. Moreover, the largest muscle activity was seen when the supporting surface was foam. Maximum CoP displacement occurred when subjects were standing on a rigid surface. Altering support surface affects both feedforward and feedback components of postural control. This information should be taken into consideration in planning rehabilitation interventions geared towards improvement of balance.
