Background: Insomnia is a common sleep-related condition that includes dissatisfaction with sleep quality, difficulty in initiating or maintaining sleep, and early morning waking. Insomnia can affect daytime functioning by causing fatigue, depression, and anxiety. Medications are the most common method for the management of insomnia but can cause adverse effects, including psychological and physical dependence, residual daytime sedation, and cognitive impairment. Acupuncture is a common traditional Chinese therapy. It has been used in the treatment of insomnia, depression, and anxiety in China. However, there are no high-quality studies focusing on acupuncture for insomnia, especially for depression and anxiety due to insomnia. Therefore, we have designed a randomized controlled trial (RCT) involving a placebo control to ensure blinding of participants to investigate the effects of acupuncture on insomnia in improving sleep quality and psychosocial symptoms.
Methods: We have designed a single-center, parallel-group, single-blinded RCT. A total of 252 participants who meet the eligibility criteria will be randomly allocated into a manual acupuncture group or sham acupuncture group in a 1:1 ratio. All participants will receive 24 sessions of acupuncture (30 min per session, three sessions per week for 8 weeks). Participants will be assessed using the Pittsburgh Sleep Quality Index score, self-assessment anxiety scale, self-assessment depression scale, and Medical Outcomes Study 36-Item Short-Form Health Survey at baseline and 8 weeks. All analyses will be based on an intention-to-treat principle. The results will be published in an international peer-reviewed journal.
Discussion: The results of this study are expected to clarify the effects of acupuncture on sleep quality and psychosocial symptoms in patients with insomnia. This will contribute to the clinical practice of acupuncture in the management of insomnia.
