Purpose : The study aim was to apply high-frequency repetitive transcranial magnetic stimulation to and investigate the effects on upper extremity function and activities of daily living. Methods : This study was conducted at Hospital D in U City from April to June 2018. Thirty-two patients diagnosed with stroke according to prior research criteria were selected and divided into two groups. Sixteen people in the experimental group received high-frequency repetitive transcranial magnetic stimulation and traditional occupational therapy, and sixteen people in the received sham stimulation and traditional occupational therapy. Both groups received 20 minutes of transcranial magnetic stimulation and 30 minutes of traditional occupational therapy per session, five times per week, for a total of 10 sessions over two weeks. Upper extremity functional evaluation, MFT and activities of daily living (Korean Version of the Modified Barthel Index, K-MBI) were conducted before and after the intervention, and an independent t test was used to confirm the effects of the intervention. Results : No statistically significant difference between the aforementioned groups’ MFT and K-MBI scores was noted before the intervention. After the intervention, however, a statistically significant difference was found in K-MBI scores (p<.001). Additionally, after the intervention, a significant difference between the groups’ MFT scores was found (p<.05). Conclusion : The results of this study showed that the combination of high-frequency repetitive transcranial magnetic stimulation and occupational therapy was effective in recovering upper extremity function and activities of daily living in patients diagnosed with acute stroke.
