Clinical Report: Impact of Acupuncture on Non-Motor Symptoms in Parkinson’s Disease
Overview
This systematic review and meta-analysis evaluates the effects of acupuncture on non-motor symptoms in Parkinson's disease, particularly focusing on sleep quality, anxiety, and fatigue. The findings suggest moderate-certainty evidence for improved sleep quality, while evidence for anxiety and fatigue remains inconclusive.
Background
Parkinson's disease (PD) is associated with significant non-motor symptoms (NMSs) that can severely impact quality of life. Traditional pharmacological treatments often provide limited relief, prompting interest in alternative therapies such as acupuncture. Understanding the efficacy of acupuncture for managing these symptoms is crucial for enhancing patient care.

Key Findings
Acupuncture shows a moderate-certainty indication for enhancing sleep quality in PD.
Pooled analysis from two RCTs indicates significant improvement in sleep quality (MD 14.52, 95% CI 7.27–21.78).
One RCT reported a significant decrease in anxiety at follow-up (HAM-A difference 7.03 points), but evidence remains inconclusive.
No significant difference in fatigue outcomes compared to sham (SMD 0.10, 95% CI −0.20 to 0.40, not significant).
No severe adverse events were reported in the studies reviewed.
Publication bias could not be formally evaluated due to the limited number of studies contributing to any outcome.
Clinical Implications
Clinicians may consider acupuncture as a supplementary therapy for improving sleep quality in patients with Parkinson's disease. However, the inconclusive evidence regarding anxiety and fatigue necessitates cautious interpretation and further research before making definitive recommendations.
Conclusion
Acupuncture may offer a beneficial adjunctive treatment for sleep disturbances in Parkinson's disease, but further multicenter RCTs are needed to validate its effects on anxiety and fatigue.
