Abstract
|
|
|
|
The purpose of this study was, via analysis of EMG signals, to determine that the motor area of the scalp acupuncture areas is correlated with regulations of motor activity of multiple muscle in the lower limbs. Experimental groups were divided into Normal, Exp I(ipsilateral stimulation group) and Exp II(contralateral stimulation group) groups.The effects on gastrocnemius muscle of hind limb in anaesthetised rats after magnetic stimulation of the motor area of the scalp acupuncture areas were as follows 1. The mean amplitude in Exp II group was significantly more increased than in Normal group after 30 minutes. (P<0.001) 2. The RMS(root mean square) in Exp II group was significantly more increased than in Normal group after 30 minutes. (P<0.005) 3. The magnetic stimulation of the motor area of the scalp acupuncture areas seems to be correlated with muscle contractibility in the contralateral lower limb. 4. After 30 minutes, the magnetic stimulation to the motor area had an significant effect on the contralateral lower limb
