| Research Abstract |
We examined the effects of observation combined with motor imagery(MI) of a skilled hand-motor task on motor cortex excitability. In the novices, the motor cortex excitability was significantly increased by video clip observation combined with MI. In contrast, MI without video clip observation significantly increased the MEP amplitude of the experts. These results suggest that action observation of a skilled hand-motor was increases the ability of novices to make their MI performing the task. Meanwhile, experts use their own motor program to recall their MI of the task. According to learning of the task, the motor cortex excitability of novice was increased in MI without video clip observation. These results suggest that action observation of a skilled hand-motor task increases the ability of novices to make their MI performing the task.
