Effects of acupuncture on sleep quality in patients with Parkinson's disease: A systematic review and meta-analysis.

Objective: To systematically evaluate the evidence relating to acupuncture on the sleep quality of patients with Parkinson's disease. Data sources: Six English-language (PubMed, Cochrane Library, EBSCOhost, Embase, OVID MEDLINE, and Web of Science) and four Chinese-language (China National Knowledge Infrastructure, SinoMed, China Scientific Journals Database, and Wanfang) databases were searched for pertinent studies published from database inception to 11 October 2023. Methods: Two researchers independently screened eligible studies and extracted relevant data using custom data extraction tables. Methodological quality assessment of the included studies was performed using Cochrane Handbook 5.1.0. Meta-analysis was performed using Cochrane Review Manager version 5.4. Results: Twenty-four studies (1701 participants) met inclusion criteria. The meta-analysis showed that acupuncture improved the Parkinson's Disease Sleep Scale, Pittsburgh Sleep Quality Index, Hamilton Anxiety Scale, Hamilton Depression Scale, Self-Rating Depression Scale, and Parkinson's Disease Questionnaire 39 scores compared with controls (all P < 0.05). Conclusion: This review showed that acupuncture improved sleep quality, anxiety and depressive symptoms, and quality of life of patients with Parkinson's disease relative to controls.
