The activation of left and right cerebral cortex induced by motion of upper limb during Mirror Therapy: MT: was studied by measuring motor-evoked potential (MEP) using trans-cranial magnetic stimulation (TMS). Subjects were 10 neurologically healthy right handed males, age 21.9 ± 1.17 and their surface muscle potential was measured using surface muscle electrical potential meter at their right first dorsal inerosseus (FDI) at resting, image training (IT), MEP during Mt were compared. Significant interaction was observed between on left and right AMEP (difference of MEP value) during IT and MT (F[3,36]-3.047, P=0.0278). MEP in stimulation of left motor area was significantly higher than right motor area stimulation (P<0.01). Promotion of neural stimulation of left cerebral cortex motor area was suggested by this study. This study also suggests the possibility of difference of MT effect for left or right cerebral hemisphere depending on the side of disturbance.
