Purpose: Functional recovery of the paretic upper extremity post stroke continues to be one the greatest challenges faced by rehabilitation professionals. Although many tasks require the coordinated participation of both hands, rehabilitation strategies for the most part have focused on the paretic limb. This study investigated whether coupled bilateral coordinated movements and repetitive high frequency TMS enhanced upper limb corticomotor excitability and motor function poststroke. Methods: For this study, we compared the neurophysiological and behavioral changes associated with two such rehabilitation protocols: coupled bilateral training and coupled unilateral training. Twenty chronic stroke patients were randomly assigned to the two training group over 8-week period. For this experiment, transcranial magnetic stumulation, EMG, Ag/AgCI suface electrode, rehabilitation training equipment, jebsen-talyer hand function kit, box & block, and pinch & power grip test kit were used. Results: First, in the box & block and JTT task, coupled bimanual group showed a reduction in movement time in comparision to receiving coupled unilateral group. Second, in the cortical excitability within affected hemisphere, using TMS, an increased in map volume, and map number following coupled bilateral group. Overall, these finding suggest that a coupled bilateral movement and high frequency repetitive TMS protocol effective in recovering upper limb motor function and cortical excitability in chronic stroke patients.
