Objective: To compare the long-term effectiveness of self-compassion therapy (SCT) combined with core stability exercise (CSE) versus CSE alone in managing nonspecific chronic low back pain (NCLBP)., Methods: The combined group received SCT and CSE, while the exercise group only received CSE. Treatment was administered once weekly for four weeks, followed by one year of follow-up. The primary outcomes were changes in functional limitations (measured by Roland and Morris Disability Questionnaire scores[RMDQ]) and self-reported back pain (measured by the Numeric Pain Rating Scale[NRS]) at 52 weeks, with assessments also conducted at 2, 4, and 16 weeks., Results: 52 (83.9%) completed the follow-up assessments and were included in the analysis (42 women [80.8%]; mean [SD] age,35.3 [10.0] years). In the combined group, the baseline mean (SD) RMDQ score was 9.3 (4.1),5.7 (5.8) at 2 weeks, 3.8 (3.4) at 4 weeks, 3.8 (3.7) at 16 weeks, and 2.4 (2.7) at 52 weeks. For the exercise group, the RMDQ scores were 8.2 (3.3) at baseline, 6.2 (4.2) at 2 weeks, 5.5 (4.7) at 4 weeks, 4.4 (4.5) at 16 weeks, and 5.2 (5.6) at 52 weeks. The estimated mean difference between the groups at 52 weeks was -3.356 points (95% CI, -5.835 to -0.878; P = 0.009), favoring the combined group. NRS scores showed similar changes., Conclusion: The addition of self-compassion therapy enhances the long-term efficacy of core stability training for NCLBP (Preregistered at chictr.org.cn:ChiCTR2100042810)., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024 The Authors.

Introduction: Low back pain (LBP) is one of the most highly prevalent pain both in developed countries and low-income and middle-income countries. Despite increasing healthcare resources and numerous treatment methods for LBP, the efficacy of these therapeutic strategies is still uncertain. Recently, core stability exercise (CSE) is popularly applied as a preventive or rehabilitative method in the treatment of LBP. However, the adequate activation of the local muscle systems of CSE needs further optimisation and quantification. This trial aims to investigate the feasibility and efficacy of CSE monitored by real-time ultrasound image (RUSI) on LBP individuals., Methods and Analysis: Forty subjects with chronic non-specific LBP (CNLBP), aged from 20 to 50 years, will be randomly allocated into two groups using sealed, consecutively numbered opaque envelopes: (1) study group (SG): CSE monitored by RUSI and (2) control group (CG): identical CSE without monitoring. Interventions will last 30 mins, two times a week for 8 weeks. The primary outcomes include pain intensity, disability and quality of life, and the secondary outcomes will be the postural control static stability, onset timing of trunk muscles activation, ultrasound images of muscle thickness and surface electromyography (sEMG) signal of muscle activities. Outcome measures will be collected at baseline, 4 and 8 weeks during training, and at 6 months follow-up. Data will be collected and analysed by an assessor blinded to group allocation. Effect sizes and mixed-model repeated measures analysis of variance (2 groups×4 time points) will be calculated., Ethics and Dissemination: This protocol and informed consent has been approved by the Institutional Research Ethics Committee of the First Affiliated Hospital, Sun Yat-sen University (Approval number: [2020] 254-1). The findings of this study will be disseminated to participants through social networks and will be submitted to peer-reviewed journals and scientific conferences., Trial Registration Number: Chinese Clinical Trial Registry (ChiCTR2000034498)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Introduction: Nonspecific chronic low back pain (NCLBP) is a leading contributor to disease burden worldwide, and the management of NCLBP has always been a problem. This study is designed to explore the feasibility and efficacy of m-health-based core stability exercise (CSE) combined with self-compassion training (SCT) and compare it with m-health-based CSE alone for the management of NCLBP. Methods: This study is a pilot, patient-blinded randomized controlled trial. Participants with NCLBP were randomized into an intervention group and a control group. All the participants received m-health-based CSE, but those in the intervention group also received SCT before CSE. The intervention took place weekly on Saturday or Sunday for 4 weeks in total. Patients self-assessed their outcomes by filling out electronic questionnaires at 4 and 16 weeks after the start of the study. The primary outcome metrics for these questionnaires were back pain disability (based on the Roland–Morris Disability Questionnaire, RMDQ) and Pain intensity (Numeric Rating Scale, NRS; current pain, worst pain, average pain). The secondary outcome metrics were anxiety (GAD-7,7-item Generalized Anxiety Disorder scale), Depression Symptoms (PHQ-9,Patient Health Questionnaire-9), pain catastrophizing (PCS, Pain Catastrophizing Scale) and Self-efficiency (PSEQ, Pain Self-Efficiency Questionnaire). Results: A total of 37 patients comprising 28 (75.7%) females completed the study, with 19 patients in the intervention group and 18 in the control group. The mean (SD) patient age was 35.2 (11.1) years. For all primary outcomes, although there were no significant differences between groups, we found that participants in the intervention group improved function and pain earlier. The RMDQ score changed by − 1.771 points (95% CI − 3.768 to 0.227) from baseline to 4 weeks in the control group and by − 4.822 points (95% CI − 6.752 to − 2.892) in the intervention group (difference between groups, − 3.052 [95% CI − 5.836 to − 0.267]). Also, the RMDQ score changed by − 3.328 points (95% CI − 5.252 to − 1.403) from baseline to 16 weeks in the control group and by − 5.124 points (95% CI − 7.014 to − 3.233) in the intervention group (difference between groups − 1.796 [95% CI − 4.501 to 0.909]). A similar pattern was found in the NRS scores. For secondary outcomes, the intervention group was superior to the control group in for GAD-7 (intervention difference from CSE along at week 16, − 2.156 [95% CI − 4.434 to − 0.122; P value for group effect was 0.030]). At the end of treatment, the improvement in PCS in the intervention group was significant (difference in PCS score at week 4, − 6.718 [95% CI − 11.872 to − 1.564]). We also found significant changes in PCS in the control group (− 6.326 [95% CI, − 11.250 to − 1.401]) at the 16-week follow-up. As for PSEQ, there were no apparent differences between the two groups. There were no adverse events relented to study participation. Conclusions: The pilot study is feasible to deliver, and our results indicate that participants in the group of m-health-based CSE combined with SCT may experience faster relief from pain intensity and back disability than those in the group of m-health-based CSE alone. Trial Registration: ChiCTR2100042810. Plain Language Summary: The impact of chronic low back pain on people's life quality and social economy is increasing year by year. Helping patients self-manage low back pain through a biological-psycho-social model seems to be an effective management approach, but the lack of connectivity between disciplines limits the development of multidisciplinary collaboration. Mindfulness-related therapy (self-compassion training) has been proven to be effective in chronic pain, and exercise therapy is widely used in rehabilitation medicine. In this study, these two programs were combined. We also used mobile health technology in the study, which brings a lot of convenience for research. The results of the study showed that the efficacy of the combined group seemed to be more obvious and worthy of further study. [ABSTRACT FROM AUTHOR]
