lateral vestibulospinal tract excitability and posture control

We investigated lateral vestibulospinal tract (LVST) excitability changes in a dynamic postural task and their relationships with postural control change. Healthy young adults performed a dynamic balance or static task, and the head jerk was evaluated during the tasks. LVST excitability was determined by the change rate in the soleus H-reflex amplitude with galvanic vestibular stimulation (GVSH). The center of pressure (COP) was examined in the eyes closed/foam rubber condition.

本研究旨在探讨动态姿势任务中，外侧前庭脊髓束（LVST）兴奋性变化及其与姿势控制变化之间的关系。健康青年受试者执行动态平衡或静态任务，并在任务过程中评估头部抖动。通过测定在电凝耳石刺激（GVSH）下比目鱼肌H反射振幅的变化率来确定LVST兴奋性。在闭眼/泡沫橡胶条件下，对压力中心（COP）进行了检查。
