Abstract: Objective To investigate the effect of electromyobiofeedback therapy combined with transcranial magnetic stimulation (rTMS) on hand dysfunction in stroke patients. Methods A total of 84 stroke patients diagnosed in China Rehabilitation Research Center from October 2022 to October 2023 were selected and divided into combined group (n=42) and electromyography group (n=42) according to different treatment methods. Both groups underwent routine stroke drug therapy and rehabilitation training. The EMG group and the combined group were combined with rTMS (1Hz on the healthy side, 10Hz stimulation on the affected side). EMG values, upper limb motor function (FMA-UE), activities of daily life (MBI), upper limb and hand Brunnstrom stages, and wrist active back extension mobility (AROM) scores were compared between stroke patients before and 1 month and 2 months after treatment. Results After 1 month and 2 months, the combined group had higher EMG values than the EMG group(P<0.05); after 1 month and 2 months, the FMA-UE and MBI of the combined group scores were higher than the EMG group (P<0.05); after 1 month and 2 months, the Brunnstrom stage and AROM of the combined group were higher than the EMG group(P<0.05). Conclusion EMG biofeedback therapy combined with rTMS can improve upper limb motor function and wrist mobility, and improve daily living activities in stroke patients.
