Abstract:

Objective To explore the therapeutic effect and mechanism of intermittent theta burst transcranial magnetic stimulation (iTBS) on non-fluent aphasia after stroke.

Methods From August, 2021 to August, 2022, 50 patients with non-fluent aphasia after stroke in the First People's Hospital of Lianyungang were randomly divided into sham stimulation group (n = 25) and iTBS group (n = 25). Both groups accepted speach training. iTBS group accepted iTBS, and the sham stimulation group received sham iTBS, for four weeks. The serum brain-derived neurotrophic factor (BDNF) was measured, and they were assessed by China Rehabilitation Research Center Standard Aphasia Examination (CRRCAE) and Boston Diagnostic Aphasia Examination before and after treatment.

Results Two cases in the sham stimulation group and three cases in iTBS group dropped down. The BDNF level, and listen and understand, repeat, name, read aloud, and total score of CRRCAE improved in two groups after treatment (|t| > 5.012, P < 0.001); and they were better in iTBS group than in the sham stimulation group (|t| > 3.968, P < 0.001). The total effective rate was more in iTBS group than in the sham stimulation group (χ2 = 8.835, P < 0.05).

Conclusion iTBS can improve speech function in patients with non-fluent aphasia after stroke, which may associate with the promotion of BDNF.
