The purpose of the study is to identify the effects of autonomic nerve activity on motor control. Activation of autonomic nerve activity was elicited by cold stimulation which is that subject immersed a hand in cold water. Postural sway during quiet standing increased by cold stimulation, and main component of postural sway is physiological tremor. In addition, surface electromyogram activity of SOL has the rhythmical activity, and its activity generates physiological activity. To examine the relation between autonomic nerve activity and physiological tremor, effects of cold stimulation on motor performance in index finger during movement matching tasks were investigated. As a result, the fluctuations from 8-12 Hz of index finger movements in optimal direction increased by cold stimulation. These results suggest that autonomic nerve activity regulates motor control via muscle spindle sensitivity.

该研究的目的是确定自主神经活动对运动控制的影响。自主神经活动的激活是由冷刺激引起的，即受试者将手浸入冷水中。安静站立时的姿势摇摆因冷刺激而增加，而姿势摇摆的主要成分是生理性震颤。另外，SOL的表面肌电活动具有节律性活动，其活动产生生理活动。为了检查自主神经活动与生理性震颤之间的关系，研究了运动匹配任务期间冷刺激对食指运动表现的影响。结果，冷刺激使食指在最佳方向上的运动在 8-12 Hz 范围内的波动增加。这些结果表明自主神经活动通过肌梭敏感性调节运动控制。
