Editorial NoteAs discussed in a recent editorial, the British Journal of Sports Medicine (BJSM) rescinds the Expression of Concern [1] for a recent network meta-analysis (NMA) [2] that was issued solely on the basis of comments by Professor Maher and colleagues [3]. The original authors (Dr Belavy and colleagues) have responded [4]. The original NMA paper did not require any changes. We editors of the BJSM have full confidence in the findings of the NMA [2]. The findings of the NMA inform clinical practice and can serve to inform clinical practice guidelines.Karim Khan, MD, PhDEditor-in-Chief, BJSMJuly 27th, 2020REFERENCES1 Expression of concern: Which specific modes of exercise training are most effective for treating low back pain?

IntroductionSurgical rates for low back pain (LBP) have been increasing in Europe, North America and Asia. Many patients treated surgically will require postsurgical rehabilitation. Little is known about the effectiveness of postsurgical rehabilitation interventions on health outcomes or about patients’ experiences with these interventions.ObjectivesTo conduct a mixed studies systematic review of quantitative and qualitative studies regarding: (1) the effectiveness and safety of postsurgical rehabilitation interventions for adults with LBP treated surgically and (2) the experiences of patients, healthcare providers, caregivers or others involved with the rehabilitation.Methods and analysisWe will search MEDLINE, Embase, PsycINFO, CINAHL, the Index to Chiropractic Literature, the Cochrane Controlled Register of Trials and the Rehabilitation & Sports Medicine Source for peer-reviewed empirical studies published from inception in any language. Studies using quantitative, qualitative and mixed methodologies will be included. We will also search reference lists of all eligible articles. Data extraction will include type of presurgical pathology, indication for surgery, surgical procedure, how the intervention was delivered and by whom, context and setting. We will conduct a quality assessment of each study and consider study quality in our evidence synthesis. We will use a sequential approach at the review level to synthesise and integrate data. First, we will synthesise the quantitative and qualitative studies independently, conducting a meta-analysis of the quantitative studies if appropriate and thematic synthesis of the qualitative studies. Then, we will integrate the quantitative and qualitative evidence by juxtaposing the findings in a matrix.Ethics and disseminationEthical approval is not required for this knowledge synthesis. Findings will be disseminated through knowledge translation activities including: (1) presentations at national and international conferences and scientific meetings; (2) presentations to local and international stakeholders; (3) publications in peer-reviewed journals and (4) posts on organisational websites.PROSPERO registration numberCRD42019134607.

Background: Exercise therapy is recommended to treat non-specific low back pain (LBP). Home-based exercises are promising way to mitigate the lack of availability of exercise centers. In this paper, we conducted a systemic review and meta-analysis on the effects of home-based exercise on pain and functional limitation in LBP. Method: PubMed, Cochrane, Embase and ScienceDirect were searched until April 20th, 2021. In order to be selected, studies needed to report the pain and functional limitation of patients before and after home-based exercise or after exercise both in a center and at-home. Random-effect meta-analyses and meta-regressions were conducted. Results: We included 33 studies and 9588 patients. We found that pain intensity decreased in the exclusive home exercise group (Effect size = −0.89. 95% CI −0.99 to −0.80) and in the group which conducted exercise both at-home and at another setting (−0.73. −0.86 to −0.59). Similarly, functional limitation also decreased in both groups (−0.75. −0.91 to −0.60, and −0.70, −0.92 to −0.48, respectively). Relaxation and postural exercise seemed to be ineffective in decreasing pain intensity, whereas trunk, pelvic or leg stretching decreased pain intensity. Yoga improved functional limitation. Supervised training was the most effective method to improve pain intensity. Insufficient data precluded robust conclusions around the duration and frequency of the sessions and program. Conclusion: Home-based exercise training improved pain intensity and functional limitation parameters in LBP.

ObjectiveExamine the effectiveness of specific modes of exercise training in non-specific chronic low back pain (NSCLBP).DesignNetwork meta-analysis (NMA).Data sourcesMEDLINE, CINAHL, SPORTDiscus, EMBASE, CENTRAL.Eligibility criteriaExercise training randomised controlled/clinical trials in adults with NSCLBP.ResultsAmong 9543 records, 89 studies (patients=5578) were eligible for qualitative synthesis and 70 (pain), 63 (physical function), 16 (mental health) and 4 (trunk muscle strength) for NMA. The NMA consistency model revealed that the following exercise training modalities had the highest probability (surface under the cumulative ranking (SUCRA)) of being best when compared with true control: Pilates for pain (SUCRA=100%; pooled standardised mean difference (95% CI): −1.86 (–2.54 to –1.19)), resistance (SUCRA=80%; −1.14 (–1.71 to –0.56)) and stabilisation/motor control (SUCRA=80%; −1.13 (–1.53 to –0.74)) for physical function and resistance (SUCRA=80%; −1.26 (–2.10 to –0.41)) and aerobic (SUCRA=80%; −1.18 (–2.20 to –0.15)) for mental health. True control was most likely (SUCRA≤10%) to be the worst treatment for all outcomes, followed by therapist hands-off control for pain (SUCRA=10%; 0.09 (–0.71 to 0.89)) and physical function (SUCRA=20%; −0.31 (–0.94 to 0.32)) and therapist hands-on control for mental health (SUCRA=20%; −0.31 (–1.31 to 0.70)). Stretching and McKenzie exercise effect sizes did not differ to true control for pain or function (p>0.095; SUCRA<40%). NMA was not possible for trunk muscle endurance or analgesic medication. The quality of the synthesised evidence was low according to Grading of Recommendations Assessment, Development and Evaluation criteria.Summary/conclusionThere is low quality evidence that Pilates, stabilisation/motor control, resistance training and aerobic exercise training are the most effective treatments, pending outcome of interest, for adults with NSCLBP. Exercise training may also be more effective than therapist hands-on treatment. Heterogeneity among studies and the fact that there are few studies with low risk of bias are both limitations.
