説明

The purpose of this study was to investigate the modifications of motor performance and changes in electrophysiological properties such as electroencephalogram (EEG) and electro-myography (EMG). The subjects consisted of six healthy males aged 18 to 24 years (mean= 21.8 years). The task of motor learning was maximum reciprocal tapping of the Ⅳand Ⅴfinger in the non-dominant hand. Practices were executed 5 days per week for 4 weeks. Parameters of analysis were rate of tapping, median power frequency properties in EEＧ and EMG during 10 seconds. The results showed significant increases in the mean rate of tapping and median power frequencies in EEＧ. Correlation between rate of tapping and median power frequency of EEＧ on the motor cortex showed a gradual increase with each week. There was no significant correlation between rate of tapping and median power frequency properties of EMG. It is suggested that an increase of neural activities in the cortex may correlate with the evolution of motor learning.
