Abstract:
Objective To investigate the effects of various intensity of 1 Hz repetitive transcranial magnetic stimulation (rTMS) on up-per limbs motor function after stroke. Methods From December, 2014 to December, 2015, sixty patients with ischemic stroke were random-ly divided into high density group (HD, n=20), low density group (LD, n=20) and control group (n=20). They all received routine rehabilita-tion and medication. The HD group received rTMS over contralesional motor cortex twice a day, while the LD group received rTMS once a day, and the control group received sham stimulation, 10 minutes a time for 10 days. They were tested with motor-evoked potentials (MEPs), Fugl-Meyer Assessment (FMA) of upper limbs and modified Barthel Index (MBI) before and after treatment. Results The ampli-tude of MEPs of the affected cortex, the scores of FMA and MBI were more in HD and LD groups than in the control group after treatment (P<0.01), and were more in HD group than in LD group (P<0.01). No serious side-effect was found. Conclusion rTMS was feasible for pa-tients with stroke to improve the upper limbs motor function. It is more effective as more times a day.
