| Research Abstract |
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.
