Efficacy of Abdomen-Rubbing Gigong Exercise for Chronic Insomnia: Study Protocol for a Randomized Controlled Trial

Abstract

BackgroundInsomnia is a common sleeping disorder which affects the quality of life which can bring harms to physical and mental health of human beings and even economic development. Traditional Chinese medicine (TCM) plays an outstanding role in treating chronic diseases and alleviating their symptoms. Therefore, the purpose of this study is to assess the treatment efficacy in patients with insomnia treated with abdomen-rubbing qigong exercise (ARQE). In addition, the brain function changes of patients will be explored by resting state functional magnetic resonance imaging(rs-fMRI).Method/designThis trial is a randomized, single-blind, controlled study planned to transpire between July 1, 2020, and July 31, 2021. A sample size of 114 participants (57 per group) with chronic insomnia will be randomly assigned to receive ARQE or CBTI for 8 weeks. The study duration will be 13 weeks, including a 1-week screening period, 8 weeks of intervention, and another 4 weeks of follow-up. The primary outcome is the Pittsburgh sleep quality index scores. Secondary outcomes include insomnia severity index, gastrointestinal symptom rating scale, the Hamilton depression scale, and rs-fMRI scan. The adverse events will be in control. DiscussionThe results of this study will help to clarify the efficacy of ARQE in the treatment of insomnia, and try to use rs-fMRI technology to explore the brain function changes of ARQE in improving sleep quality in patients with insomnia disorder. If the results are as expected, this study will provide high-quality evidence for the treatment of insomnia with ARQE.
