以生理指標驗證音樂對失眠改善成效之系統性文獻回顧與統合分析

Insomnia is common and has various underlying causes, and it can cause significant physical and psychological distress. Numerous studies have explored the benefits of music therapy in insomnia. However, most have considered subjective patient perspectives instead of objective physiological indices. Therefore, we conducted a systematic review and meta-analysis to investigate the effect of music therapy on insomnia, with brain waves or polysomnography as measurement indicators. We searched the Cochrane Library, PubMed, Embase, CINHAL, and NCL Periodical Information Center databases for randomized controlled trials and the keywords were insomnia, music, and physical indicator. The inclusion criteria were: (1) adults with insomnia, (2) music therapy as the intervention strategy, and (3) outcomes measured through electroencephalography or polysomnography. The exclusion criteria were: (1) insufficient experimental data; (2) those that included other interventions; (3) incomplete articles. We performed data analysis using RevMan5. Finally, we included and analyzed four studies. Music therapy did not significantly alleviate insomnia (heterogeneity I^2 = 22%, p = 0.33). The studies related to physical measurement for insomnia were still few, more evidence should be explored in the future to provide effective strategies.
