Background: Although existing studies have shown that both repetitive transcranial magnetic stimulation (rTMS) and music therapy have advantages in the treatment of non-fluent aphasia, the efficacy of the combination of these two methods remains to be investigated. Aims: To investigate the clinical efficacy of low-frequency rTMS combined with music therapy on language function and depression in patients with non-fluent aphasia after stroke. Methods & Procedures: A single-blind parallel randomised controlled trial was conducted. Sixty patients (mean duration = 93.78 days) with non-fluent aphasia after stroke were randomly divided into a traditional therapy group (n = 20), a music therapy group (n = 20) and a combined therapy group (n = 20, 1 Hz). The language function and depression were evaluated before and 3 weeks after treatment with the Chinese version of the Western Aphasia Battery scale, Boston Diagnostic Aphasia Examination scale and Stroke Aphasic Depression Questionnaire Hospital Version scale. Outcomes & Results: The combined therapy group was significantly better in all outcomes than the traditional therapy group and was significantly better in depression than the music therapy group. The music therapy group was significantly better in repetition and depression than the traditional therapy group. Language improvement was positively correlated with depression improvement. For adverse events, only two patients in the combined therapy group showed slight dizziness during rTMS treatment and their symptoms improved after rest. Conclusions & Implications: Our preliminary randomised controlled study indicates that low-frequency rTMS combined with music therapy is feasible and safe in improving language function and depression in non-fluent aphasia patients after stroke.
