Clinical Effect of High-Frequency Repetitive Transcranial Magnetic Stimulation on Upper Limb Motor Function in Patients with Hemiplegia after Stroke
Objective To investigate the effect of high-frequency repetitive transcranial magnetic stimulation on upper limb motor function in patients with hemiplegia after stroke.Methods Fifty patients with post-stroke hemiplegia admitted to the First Affiliated Hospital of Guangdong Pharmaceutical University from September 2020 to November 2021 were selected as the research objects,and were divided into a experimental group and a control group according to random number table method,with 25 cases in each group.On the basis of conventional rehabilitation treatment,the experimental group was treated with 5 Hz repeated transcranial magnetic stimulation of the M1 area on the affected side,and the control group was treated with transcranial magnetic pseudo-stimulation.Motor evoked potential amplitude,grip strength and upper limb motor function were compared between the two groups.Results After treatment,the motor evoked potential amplitude and grip strength of both groups were higher than those before treatment,and the experimental group were higher than those in the control group,the Fugl-Meyer Assessment-Upper Extremities score in both groups was higher than those before treatment,and the Fugl-Meyer Assessment-Upper Extremities score in the experimental group was(37.04±11.26)points,which was higher than(31.00±9.69)points of the control group,and the differences were statistically significant(P<0.05).Conclusion High-frequency repetitive transcranial magnetic stimulation in the M1 region of the affected side can improve the amplitude of motor evoked potentials and improved the motor function of the upper limbs of stroke patients with hemiplegia.
