Potential benefits of music-based therapies on rehabilitation outcomes in people with multiple sclerosis: a systematic review

OBJECTIVES: To assess the evidence for a benefit of music-based therapies (MBTs) on rehabilitation outcomes in adults with multiple sclerosis (MS). SETTING: Scholarly literature (published in English) from any country. This systematic review received no specific funding and was registered on PROSPERO as CRD420251083656. DATA SOURCES: Six bibliographic databases: AMED (Ebsco), APA PsycINFO (Ovid), CINAHL (Ebsco), Cochrane CENTRAL, EMBASE (Ovid) and MEDLINE (Ovid), plus supplementary searches and citation chasing (search date July 2025). PRIMARY AND SECONDARY OUTCOME MEASURES: Eligible studies used a clinical trial or controlled quantitative observational study design to assess the benefit of MBTs on rehabilitation outcomes in adults with MS. Risk of bias was assessed using Critical Appraisal Skills Programme checklists. Data were synthesised using narrative synthesis. RESULTS: 23 studies were included (955 participants, of whom 880 people had MS and 691 received MBTs). The most frequently assessed outcome was motor function (16 studies), followed by quality of life (12 studies). Evidence suggests potential benefits for MBTs, particularly rhythmic auditory stimulation and music-cued motor imagery, on gait and mobility outcomes, including walking speed, walking distance, cadence, stride length and gait symmetry. Findings for other outcomes were less clear. CONCLUSIONS: MBTs may benefit people with MS, with the most consistent evidence observed for gait and mobility outcomes. However, heterogeneity in intervention type, study design and outcome measurement limits the strength of conclusions. Higher-quality, adequately powered trials with standardised outcomes and direct comparisons between MBTs are needed to clarify effectiveness and inform clinical implementation.
