A Comparison Study of Cerebral Cortical Activity at Chronic Stroke Patients According to Differences in Frequency of Repetitive Transcranial Magnetic Stimulation: Randomized Controlled Trial

초록

This study aimed to characterize the cerebral cortical activity of chronic stroke patients according to differences in frequency of repetitive transcranial magnetic stimulation (rTMS). 20 chronic stroke patients were treated with 5 Hz high-frequency rTMS group (HFG) applied to the cerebral cortex on the damaged side and 1 Hz low-frequency rTMS group (LFG) applied to the cerebral cortex on the non-damaged side. The activity of the cerebral cortex was examined using electroencephalography (EEG) to changes in alpha waves (a-wave) and sensorimotor rhythm (SMR) wave. As a result, in two groups, HFG showed a significant difference in F3 and P4 for a-wave and in F3 and F4 for SMR wave (p<0.05) (p<0.05). In LFG, there was no significant difference in a-wave, but SMR wave showed a significant difference in F4 (p>0.05) (p<0.05). And in the comparison between two groups, a-wave showed a significant difference in F3 (p<0.05). SMR wave showed no significant difference (p>0.05). Through this, it is judged that 5 Hz high-frequency rTMS has a positive effect on cerebral cortical activity in chronic stroke patients compared to 1 Hz low-frequency rTMS.
