The association between physical activity and low back pain: a systematic review and meta-analysis of observational studies.

ABSTRACT: The aim of this review was to investigate the association between total and domain-specific physical activity (PA) and non-specific low back pain (LBP) in adults. Seven databases were searched for cohort and cross-sectional studies. Pooled estimates of the association of medium and high levels PA and LBP, using the generic inverse-variance method with fixed- and random-effects models were calculated. Twenty-four studies (15 cohort and nine cross-sectional; 95,796 participants) were included. The pooled fully adjusted risk ratios (RR) from cohort studies comparing medium with lowest activity levels were 0.90 (95%CI 0.85 to 0.96) for total PA, and 0.90 (95%CI 0.85 to 0.96) for leisure-time PA (LTPA). The pooled RR comparing highest with lowest activity levels were 1.00 (95%CI 0.92 to 1.08) for total PA, and 1.01 (95%CI 0.93 to 1.10) for LTPA. The pooled fully adjusted odds ratios (OR) from cross-sectional studies comparing medium with lowest activity levels were 0.93 (95%CI 0.65 to 1.32) for total PA, and 0.77 (95%CI 0.62 to 0.96) for LTPA. The pooled OR comparing highest with lowest activity levels were 1.05 (95%CI 0.89 to 1.23) for total PA, and 0.85 (95%CI 0.79 to 0.93) for LTPA. PA seems to be associated with lower prevalence of LBP.

Project description:BackgroundChronic low back pain is a common musculoskeletal disease. With the increasing number of patients, it has become a huge economic and social burden. It is urgent to relieve the burden of patients. There are many common rehabilitation methods, and aquatic physical therapy is one of them. The purpose of this systematic review and meta-analysis is to summarize the existing literature and analyze the impact of aquatic physical therapy on pain intensity, quality of life and disability of patients with chronic low back pain.MethodsThrough 8 databases, we searched randomized controlled trials on the effect of aquatic physical therapy on patients with chronic low back pain. These trials published results on pain intensity, quality of life, and disability. This review is guided by Cochrane Handbook for systematic reviews of interventions version 5.1.0. The level of evidence was assessed through GRADE.ResultsA total of 13 articles involving 597 patients were included. The results showed that compared with the control group, aquatic physical therapy alleviated the pain intensity (Visual Analogue Scale: SMD = -0.68, 95%CI:-0.91 to -0.46, Z = 5.92, P < 0.00001) and improved quality of life (physical components of 36-Item Short Form Health Survey or Short-Form 12: SMD = 0.63, 95%CI:0.36 to 0.90, Ζ = 4.57, P < 0.00001; mental components of 36-Item Short Form Health Survey or Short-Form 12: SMD = 0.59, 95%CI:0.10 to 1.08, Ζ = 2.35, P = 0.02), and reduced disability (Roland Morris Disability Questionnaire: SMD = -0.42, 95%CI:-0.66 to -0.17, Ζ = 3.34, P = 0.0008; Oswestry Disability Index or Oswestry Low Back Pain Disability Questionnaire: SMD = -0.54, 95%CI:-1.07 to -0.01, Ζ = 1.99, P = 0.05). However, aquatic physical therapy did not improve patients' pain at rest (Visual Analogue Scale at rest: SMD = -0.60, 95%CI:-1.42 to 0.23, Ζ = 1.41, P = 0.16). We found very low or low evidence of effects of aquatic physical therapy on pain intensity, quality of life, and disability in patients with chronic low back pain compared with no aquatic physical therapy.ConclusionsOur systematic review showed that aquatic physical therapy could benefit patients with chronic low back pain. However, because the articles included in this systematic review have high bias risk or are unclear, more high-quality randomized controlled trials are needed to verify.

Project description:Low back pain accounts for nearly 4 million emergency department (ED) visits annually and is a significant source of disability. Physical therapy has been suggested as a potentially effective nonopioid treatment for low back pain; however, no studies to our knowledge have yet evaluated the emerging resource of ED-initiated physical therapy. The study objective was to compare patient-reported outcomes in patients receiving ED-initiated physical therapy and patients receiving usual care for acute low back pain. This was a prospective observational study of ED patients receiving either physical therapy or usual care for acute low back pain from May 1, 2018, to May 24, 2019, at a single academic ED (>91,000 annual visits). The primary outcome was pain-related functioning, assessed with Oswestry Disability Index (ODI) and Patient-Reported Outcomes Measurement Information System pain interference (PROMIS-PI) scores. The secondary outcome was use of high-risk medications (opioids, benzodiazepines, and skeletal muscle relaxants). Outcomes were compared over 3 months using adjusted linear mixed and generalized estimating equation models. For 101 participants (43 receiving ED-initiated physical therapy and 58 receiving usual care), the median age was 40.5 years and 59% were women. Baseline outcome scores in the ED-initiated physical therapy group were higher than those in the usual care group (ODI = 51.1 vs 36.0; PROMIS-PI = 67.6 vs 62.7). Patients receiving ED-initiated physical therapy had greater improvements in both ODI and PROMIS-PI scores at the 3-month follow-up (ODI = -14.4 [95% CI = -23.0 to -5.7]; PROMIS-PI = -5.1 [95% CI = -9.9 to -0.4]) and lower use of high-risk medications (odds ratio = 0.05 [95% CI = 0.01 to 0.58]). In this single-center observational study, ED-initiated physical therapy for acute low back pain was associated with improvements in functioning and lower use of high-risk medications compared with usual care; the causality of these relationships remains to be explored. ED-initiated physical therapy is a promising therapy for acute low back pain that may reduce reliance on high-risk medications while improving patient-reported outcomes. Emergency department-initiated physical therapy for low back pain was associated with greater improvement in functioning and lower use of high-risk medications over 3 months.

Project description:IntroductionThe association between occupational mechanical exposures and chronic low back pain (LBP) has been widely studied, however, few systematic reviews have evaluated the evidence of an association. Furthermore, little is known of the impact of occupational psychosocial exposures on chronic LBP. The aim of this systematic review and meta-analysis is to study the association between occupational mechanical and psychosocial exposures and chronic LBP.MethodsThe study will be conducted as a systematic review using another systematic review published in 2014 as basis and has been registered in the International Prospective Register of Systematic Reviews (PROSPERO) with registration number CRD42021281996. A systematic literature search will be performed in 6 scientific databases to identified potential relevant studies published after 2014. Studies will systematically be excluded through a screening process performed independently by 2 reviewers. Exposures will include occupational mechanical and psychosocial exposures, and outcome will include chronic LBP (LBP ≥3 months, "degenerative" diseases, and lumbosacral radiculopathy). Study population will include persons in or above working age, and study designs will comprise cohort and case-control studies. The quality of each included study will be methodologically assessed by 2 independent reviewers and level of evidence of an association will be graded using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system. In meta-analyses, effect sizes will be addressed using random-effect models, sensitivity analyses will explore the robustness of the meta-analysis, and heterogeneity assessed.DiscussionThis systematic review and meta-analysis will assess the evidence available of the association between occupational mechanical and psychosocial exposures and chronic LBP. The review can provide essential knowledge on the association, exposure-response relationships, thresholds, which may pave the way for political decisions on the occupational environment and the labour market insurance policy.
