Abstract:

Objective To explore the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) on upper limb motor function in hemiplegic patients after stroke.Methods From August, 2018 to July, 2019, 60 patients with hemiplegia after stroke were randomly divided into control group (n = 30) and observation group (n = 30). Both groups received conventional treatment. The observation group accepted 5 Hz rTMS to ipsilesional hemisphere premotor areas for three weeks. The control group received sham stimulation. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Brunnstrom stages, modified Ashworth Scale (MAS), modified Barthel Index (MBI) and Wolf Motor Function Test before and after treatment.Results Two patients dropped in the control group. After treatment, the scores of FMA-UE, MBI and Wolf Motor Function Test improved in both groups (|t| > 3.686, P< 0.01), and the difference values of FMA-UE and Wolf Motor Function Test before and after treatment were more in the observation group than in the control group (|t| > 2.119, P< 0.05).Conclusion High-frequency rTMS to ipsilesional hemisphere premotor areas could improve the recovery of upper limb and hand motor function in hemiplegic patients after stroke.
