This systematic review and meta-analysis examined previous studies on music-based interventions for individuals with Parkinson's disease (PD). The effectiveness of the interventions on various motor and non-motor outcomes was evaluated. This review was conducted by searching PubMed, CINAHL, PsycINFO, and Cochrane Library CENTRAL prior to June 2022 for randomized controlled trial (RCT) and controlled clinical trial (CCT) studies published in English. Data were expressed as weighted/standardized mean difference (MD/SMD) with 95% confidence intervals (CI). I-2 index was used for heterogeneity. The initial search identified 745 studies, and 13 studies involving 417 participants with PD which met the inclusion criteria included in this review. The results of the meta-analysis revealed that music-based interventions can significantly improve walking velocity (MD = 0.12, 95% CI = 0.07 similar to 0.16, p < 0.00001), stride length (MD = 0.04, 95% CI = 0.02 similar to 0.07, p = 0.002), and mobility (MD = -1.05, 95% CI = -1.53 similar to-0.57, p < 0.0001). However, the results did not support significant effects for music-based interventions on cadence (MD = 3.21, 95% CI = -4.15 similar to 10.57, p = 0.39), cognitive flexibility (MD = 20.91, 95% CI = -10.62 similar to 52.44, p = 0.19), inhibition (SMD = 0.07, 95% CI = -0.40 similar to 0.55, p = 0.76), and quality of life (SMD = -0.68, 95% CI= -1.68 similar to 0.32, p = 0.18). The findings suggest that music-based interventions are effective for the improvement of some motor symptoms, but evidence for non-motor symptoms is limited. Further high-quality studies with a larger sample size are required to obtain the robust effects of music-based interventions on various outcomes among patients with PD.
