Abstract:
ObjectiveTo investigate the effect of 1 Hz repetitive transcranial magnetic stimulation (rTMS) combined with mirror therapy on upper limb motor function and cortical neurophysiological indicators in stroke patients with hemiplegia. MethodsSixty stroke patients who were admitted to Jinshan Hospital of Fudan University, from October, 2022 to March, 2023 were randomly assigned to control group (n = 15), rTMS group (n = 15), mirror therapy group (n = 15) and combined group (n = 15). All groups received routine medicine and rehabilitation. In addition, the control group received sham rTMS and sham mirror therapy, rTMS group received 1 Hz rTMS and sham mirror therapy, the mirror therapy group received sham rTMS and mirror therapy, and the combined group received 1Hz rTMS combined with mirror therapy, for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Action Research Arm Test (ARAT) were used to evaluate the motor function of the affected upper limb. The motor-evoked potential (MEP) amplitude and central motor conduction time (CMCT) of the affected cortex were measured using a transcranial magnetic stimulation device. ResultsAfter treatment, the scores of FMA-UE and ARAT, and the amplitude of MEP significantly improved in all groups (|t| > 3.854, P < 0.001), while the CMCT significantly shortened (t > 5.967, P < 0.001). Compared to the control group, rTMS group, the mirror therapy group and the combined group showed more significant improvement in the scores of FMA-UE and ARAT, and the amplitude of MEP, and shorter CMCT (P < 0.05). When compared to rTMS group and the mirror therapy group, the combined group showed more significant improvement the scores of FMA-UE and ARAT, and the amplitude of MEP, and shorter CMCT (P < 0.05). There was significant positive correlation of the scores of FMA-UE and ARAT with the amplitude of MEP, and negative correlation with the CMCT in all groups (R2 > 0.804, P < 0.001). ConclusionThe combination of 1 Hz rTMS and mirror therapy contributes to the post-stroke brain functional remodeling and facilitates upper limb motor recovery in stroke patients with hemiplegia.
