Efficacy and safety of a combination of emotional freedom technique with acupuncture versus acupuncture alone to treat psychiatric symptoms in Parkinson’s disease: A protocol for a randomized, assessor-blind, parallel-group clinical trial

Parkinson’s disease (PD) is one of the most prevalent neurodegenerative diseases in world. As some psychiatric symptoms degrade the quality of life of patients with PD, a novel alternative non-pharmacological treatment is required. Acupuncture appears to be an effective and safe treatment for PD. The emotional freedom technique (EFT) is a type of psychological therapy that alleviates psychiatric symptoms by stimulating acupoints. In this study, we will compare the efficacy and safety of a combination of the EFT and acupuncture and acupuncture alone. METHODS: This study is a randomized, assessor-blind, parallel-group clinical trial. Eighty participants will be equally divided into experimental and control groups. Each participant will receive a total of 24 interventions over 12 weeks. The experimental group will receive EFT combined with acupuncture and the control group will receive acupuncture alone. The primary outcome is the change in the Beck Depression Inventory score from baseline to 12 weeks, and the secondary outcomes include change in the following variables: Beck Depression Inventory, Parkinson’s disease sleep scale, State-Trait Anxiety Inventory, the Korean version of the Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight questionnaire scale, and unified Parkinson’s disease rating scale III and exercises. DISCUSSION: Acupuncture is a safe and effective treatment for motor and nonmotor symptoms in PD, and EFT appears to be safe and effective for a variety of psychiatric symptoms. In this study, we will investigate the potential of EFT combined with acupuncture to improve psychiatric symptoms in PD.
