Objective
The aim of this meta-analysis was to evaluate the evidence on the effectiveness of music therapy in the recovery of language function in post-stroke aphasia, compared with conventional therapy or no therapy.
Methods
We searched studies that explored the effect of music therapy on language function in post-stroke aphasia and published in PubMed, Embase, the Cochrane Library, Web of Science, CINAHL, ProQuest Digital Dissertations, and ClinicalTrials.gov from inception to March 2021. Six reviewers independently screened out eligible studies, extracted data, and evaluated the methodological quality. Results were pooled using mean difference (MD) with 95% confidence interval (CI). Heterogeneity was assessed by the chi-square test and I2 statistic.
Results
Six studies were included in this meta-analysis involving 115 patients. The methodological quality of these studies ranged from poor to excellent. There was significant mean difference in functional communication for post-stroke aphasia by 1.45 (95% CI: 0.24, 2.65; P = 0.02, from poor to excellent evidence), in repetition by 6.49 (95% CI: 0.97, 12.00; P = 0.02, from acceptable to excellent evidence), and in naming by 11.44 (95% CI: 1.63, 21.26; P = 0.02, from acceptable to excellent evidence). But there was no significant difference in comprehension for post-stroke aphasia by 7.21 (95% CI: − 10.88, 25.29; P = 0.43, from acceptable to excellent evidence).
Conclusions
Music therapy can improve functional communication, repetition, and naming in patients with post-stroke aphasia, but did not significantly improve comprehension.
