| Outline of Final Research Achievements |
Ipsilateral motor cortex activation, associated with a complex motor task, showed symmetrical in both hemispheres before motor learning. However, ipsilateral activation was significantly reduced only in left motor cortex after a short-term period of exercise. The results show that left-hemisphere motor dominance relates to ipsilateral motor cortex activation during unimanual hand movements. Additionally, short-interval intracortical inhibition was decreased before muscle relaxation, and this was followed immediately by a temporary activation of motor cortex. The findings suggest that cortical activation in early stage plays an important role in muscle relaxation control.
An intervention to facilitate motor cortex activation associated with motor control would be more effective in rehabilitation.
