A Comparative Study of 5 Hz Repetitive Transcranial Magnetic Stimulation on Cortical Activity and Upper Limb Function in Chronic Stroke Patients with Different Stroke Etiologies: A Case Study

초록

The purpose of this study was to investigate the effect of 5Hz repetitive transcranial magnetic stimulation (rTMS) on cortical activity and upper limb function in the etiology of chronic stroke patients. 2 patients with ischemic stroke and 2 patients with hemorrhagic stroke who satisfied the selection criteria were selected using the ABA' single subjective design. The study period was applied 18 times in all 4 patients: 3 times at baseline (A), 12 times in intervention period (B), and 3 times in baseline (A'). During intervention period(B), 5Hz rTMS was applied 4 times a week for 3 weeks, and no intervention was performed during the 3 baseline (A) and baselines (A'). Electroencephalography (EEG), box and block test (BBT), and fugl-meyer assessment (FMA) were performed to investigate changes in cortical activity and upper limb function. As a result, EEG and BBT were changed after intervention (B) in ischemic stroke patients than in hemorrhagic stroke patients, and there was no difference in FMA of all stroke patients. Through this, it is thought that 5 Hz r TMS can help to improve cortical activity and upper limb function in ischemic stroke rather than hemorrhagic stroke.
