Efficacy and Safety of Electroacupuncture on Insomnia in Parkinson's Disease: A Multicentre, Randomized, Controlled Trial.

Parkinson's disease affects movement, but many patients also struggle with sleep problems, particularly insomnia, which significantly impacts quality of life. Current medications for insomnia in Parkinson's often come with unwanted side effects and may not be accessible to everyone. Researchers in China conducted a large study to test whether electroacupuncture—a form of acupuncture that adds mild electrical stimulation to the needles—could help improve sleep in people with Parkinson's disease.

The study included 136 patients with both Parkinson's disease and insomnia, recruited from eight medical centers across China. Half received real electroacupuncture while the other half received sham (fake) electroacupuncture as a comparison. Neither the patients nor the assessors knew which treatment was being given. Participants received treatments over eight weeks and were then followed for an additional 12 weeks.

The results were promising. Both groups improved, but those receiving real electroacupuncture showed significantly greater improvements in sleep quality scores. The electroacupuncture group experienced better results across multiple sleep measures, including how severe their insomnia was, daytime sleepiness, and objective sleep measurements taken in a sleep laboratory. These improvements lasted throughout the 12-week follow-up period, and no serious side effects occurred.

For patients with Parkinson's disease struggling with insomnia, this study provides strong evidence that electroacupuncture may be a safe and effective treatment option. The benefits appear to be sustained over time without the side effects associated with sleep medications. If you're considering this approach, work with a qualified, licensed acupuncturist experienced in treating neurological conditions.

This multicenter, participant-and assessor-blinded, randomized sham-controlled trial evaluated electroacupuncture (EA) efficacy for insomnia in Parkinson's disease (PD). Conducted across eight Chinese sites from March to October 2024, the study randomized 136 PD patients with insomnia to EA or sham electroacupuncture (SA) groups (n=68 each) for 8 weeks with 12-week follow-up.

The primary outcome, PDSS score change at week 8, showed significant between-group difference favoring EA (13.50 points [95%CI, 12.68-14.32]). Secondary outcomes including Insomnia Severity Index, Epworth Sleepiness Scale, and polysomnography parameters all demonstrated superior improvements in the EA group. Treatment effects persisted through follow-up without severe adverse events. Blinding integrity was maintained throughout.

This Class I evidence supports EA integration into PD insomnia management as a safe, effective non-pharmacological intervention with sustained benefits. The robust methodology and clinically meaningful effect sizes make this relevant for practitioners treating sleep disorders in neurodegenerative conditions.
