Efficacy of acupuncture in ameliorating anxiety in Parkinson's disease: a systematic review and meta-analysis with trial sequential analysis

Although numerous studies have explored acupuncture for alleviating Parkinson's disease (PD) symptoms, specific methods focusing on reducing anxiety in these patients are lacking. Preliminary research indicates that acupuncture may improve anxiety in patients with Parkinson's; however, high-quality evidence is lacking. Therefore, we conducted a meta-analysis and trial sequential analysis (TSA) to assess the efficacy of acupuncture in managing anxiety symptoms in PD.
