Effect of Self-Compassion Training Combined With Core Stability Exercise For Patients With Non-Specific Chronic Low Back Pain: Study Protocol For A Randomized Controlled Trial

Abstract Background: Non-specific chronic low back pain (NCLBP) has a high incidence, which has a significant impact on a patient's body and mind, and is a common condition affecting people's quality of life. Core Stability Exercise (CSE) is a modestly effective treatment for NCLBP; however, NCLBP has only been shown to be a useful treatment option in the short-term. Many clinical practice guidelines recommend the use of a biopsychosocial framework to guide management of NCLBP. Self-Compassion Training（SCT）is a promising psychotherapy treatment option for NCLBP; however, there is still a lack of research on CSE combined with SCT. In this study, we will seek to determine whether CSE combined with SCT is an effective treatment option for patients with NCLBP compared to CSE alone.Methods: In this study, we will randomize 60 adults with NCLBP to a combined SCT and CSE arm or a CSE alone arm (30 participants per group). Both interventions will consist of four weekly 1.5-hour group sessions of CSE supplemented by home practice. The combined group protocol also includes 2 hours of SCT before CSE. Interviewers masked to the treatment assignments will assess outcomes at 4 and 12 weeks post-randomization. The primary outcomes will be back pain disability (based on the Roland-Morris Disability Questionnaire) and Pain intensity (NRS; average pain, worst pain, average pain) at 12 weeks.Discussion: If SCT is found to enhance the effectiveness of CSE for patients with chronic back pain, the results of the study may promote the development of mind–body therapies for chronic low back pain.Trial registration: The trial was prospectively registered with the Chinese Clinical Trials Registry Number:ChiCTR2100042810 .Registered on 21 Jan 2021.
