〔Abstract〕 Objective To study the clinical effect of repeated transcranial magnetic stimulation (rTMS) in the treatment of aphasia after stroke, and to promote the standardization of rehabilitation and diagnosis of aphasia after stroke. Methods From December 2018 to October 2020, 26 patients with aphasia after stroke who met the inclusion criteria of this study were selected, and the patients were divided into control group (14 cases) and treatment group (12cases) by random number table method. The treatment group was treated with rTMS combined with speech rehabilitation training, while the control group was treated with conventional speech rehabilitation training. Patients in each group were treated once a day, 5 times a week for 2 weeks. Before and after treatment, patients were scored by Western Complete Aphasia Scale (WAB) and modified Boston Diagnostic Aphasia Test (BDAE), and the clinical differences between the two groups were compared before and after treatment. Results The scores of Western Complete Aphasia Scale (WAB) were improved signifi cantly in both groups. The difference between the two groups was statistically signifi cant (P < 0.05). The modifi ed Boston diagnostic aphasia test (BDAE) was improved.After treatment, there was a statistically signifi cant difference in the increase of BDAE grade between the two groups (P < 0.05). Conclusion RTMS combined with speech rehabilitation training in the treatment of post-stroke aphasia can effectively improve the ability of conversation, understanding, retelling and naming, improve the ability of language communication, improve the ability of daily living and improve the quality of life of patients.
