Background: Low back pain (LBP) is a common musculoskeletal problem globally. Updating the prevalence and burden of LBP is important for researchers and policy makers. This paper presents, compares and contextualizes the global prevalence and years lived with disability (YLDs) of LBP by age, sex and region, from 1990 to 2017.

Methods: Data were extracted from the GBD (the Global Burden of Disease, Injuries, and Risk Factors Study) 2017 Study. Age, sex and region-specific analyses were conducted to estimate the global prevalence and YLDs of LBP, with the uncertainty intervals (UIs).

Results: The age-standardized point prevalence of LBP was 8.20% (95% UI: 7.31-9.10%) in 1990 and decreased slightly to 7.50% (95% UI: 6.75-8.27%) in 2017. The prevalent numbers of people with LBP at any one point in time in 1990 was 377.5 million, and this increased to 577.0 million in 2017. Age-standardized prevalence of LBP was higher in females than males. LBP prevalence increased with age, and peaked around the ages of 80 to 89 years, and then decreased slightly. Global YLDs were 42.5 million (95% UI: 30.2 million-57.2 million) in 1990 and increased by 52.7% to 64.9 million (95% UI: 46.5 million-87.4 million) in 2017. YLDs were also higher in females than males and increased initially with age; they peaked at 35-39 years of age in 1990, before decreasing, whereas in 2017, they peaked at 45-49 years of age, before decreasing. Western Europe had the highest number of LBP YLDs.

Objective: The purpose of this study is to summarize the evidence for the association between exposure to a motor vehicle collision (MVC) and future low back pain (LBP).

Literature survey: Persistent low back pain (LBP) is a relatively common complaint after acute injury in a MVC, with a reported 1 year post-crash prevalence of at least 31 % of exposed individuals. Interpretation of this finding is challenging given the high incidence of LBP in the general population that is not exposed to a MVC. Risk studies with comparison control groups need to be examined in a systematic review.

Methodology: A systematic search of five electronic databases from 1998 to 2019 was performed. Eligible studies describing exposure to a MVC and risk of future non-specific LBP were critically appraised using the Quality in Prognosis Studies (QUIPS) instrument. The results were summarized using best-evidence synthesis principles, a random effects meta-analysis and testing for publication bias.

Synthesis: The search strategy yielded 1,136 articles, three of which were found to be at low to medium risk of bias after critical appraisal. All three studies reported a positive association between an acute injury in a MVC and future LBP.

Background: The inflammatory profiles of patients with acute and chronic nonspecific low back pain (LBP) patients are distinct. Spinal manipulative therapy (SMT) has been shown to modulate the production of nociceptive chemokines differently in these patient cohorts. The present study further investigates the effect(s) of SMT on other inflammatory mediators in the same LBP patient cohorts.

Methods: Acute (n = 22) and chronic (n = 25) LBP patients with minimum pain scores of 3 on a 10-point numeric scale, and asymptomatic controls (n = 24) were recruited according to stringent exclusion criteria. Blood samples were obtained at baseline and after 2 weeks during which patients received 6 SMTs in the lumbar or lumbosacral region. The in vitro production of tumor necrosis factor (TNFα), interleukin-1 β (IL-1β), IL-6, IL-2, interferon γ (IFNγ), IL-1 receptor antagonist (IL-1RA), TNF soluble receptor type 2 (sTNFR2) and IL-10 was determined by specific immunoassays. Parametric as well as non-parametric statistics (PAST 3.18 beta software) was used to determine significance of differences between and within study groups prior and post-SMT. Effect size (ES) estimates were obtained using Cohen’s d.

Effects of Chiropractic Care on Strength, Balance, and Endurance in Active-Duty U.S. Military Personnel with Low Back Pain

Effects of Chiropractic Care on Strength, Balance, and Endurance in Active-Duty U.S. Military Personnel with Low Back Pain: A Randomized Controlled Trial

Objectives: To investigate whether chiropractic care influences strength, balance, and/or endurance in active-duty United States military personnel with low back pain (LBP).

Design: This study employed a prospective randomized controlled trial using a pragmatic treatment approach. Participants were randomly allocated to 4 weeks of chiropractic care or to a wait-list control. Interventions: Chiropractic care consisted of spinal manipulation, education, advice, and reassurance.

Settings/Location: Naval Air Technical Training Center branch clinic at the Naval Hospital Pensacola Florida.

Subjects: One hundred ten active-duty military personnel 18-40 years of age with self-reported LBP.

Outcome measures: Isometric pulling strength from a semisquat position was the primary outcome. Secondary outcomes were single-leg balance with eyes open and eyes closed, and trunk muscle endurance using the Biering-Sorensen test. Patient-reported outcomes such as pain severity and disability were also measured. Outcomes were measured at baseline and 4 weeks. Linear mixed-effects regression models over baseline and 4 weeks were used for analysis.

Results: Participants had mean age of 30 years (18-40), 17% were female, 33% were non-white, and 86% reported chronic LBP.

Care for Low Back Pain: Can Health Systems Deliver?

Care for Low Back Pain: Can Health Systems Deliver?

Low back pain is the leading cause of years lived with disability globally. In 2018, an international working group called on the World Health Organization to increase attention on the burden of low back pain and the need to avoid excessively medical solutions. Indeed, major international clinical guidelines now recognize that many people with low back pain require little or no formal treatment. Where treatment is required the recommended approach is to discourage use of pain medication, steroid injections and spinal surgery, and instead promote physical and psychological therapies. Many health systems are not designed to support this approach.

In this paper we discuss why care for low back pain that is concordant with guidelines requires system-wide changes. We detail the key challenges of low back pain care within health systems. These include the financial interests of pharmaceutical and other companies; outdated payment systems that favour medical care over patients’ self-management; and deep-rooted medical traditions and beliefs about care for back pain among physicians and the public. We give international examples of promising solutions and policies and practices for health systems facing an increasing burden of ineffective care for low back pain.

We suggest policies that, by shifting resources from unnecessary care to guideline-concordant care for low back pain, could be cost-neutral and have widespread impact. Small adjustments to health policy will not work in isolation, however. Workplace systems, legal frameworks, personal beliefs, politics and the overall societal context in which we experience health, will also need to change.

Primary Care for Low Back Pain

Primary Care for Low Back Pain: We Don’t Know the Half of It

Evidence-based medicine helps health care professionals and patients decide best care, drawing on research about effectiveness and safety of interventions. Systematic reviews summarise the evidence; guidelines report consensus between experts (including patients) on interpreting it for everyday practice. Although guideline recommendations are only one component of shared decisions that will vary patient-to-patient, the hoped-for outcome is health benefit for each individual. Guidelines also inform starker decisions by policymakers and health care leaders — for example, when to withdraw approval or funding for a poorly evidenced or harmful intervention. To assess whether all this research-driven activity is useful, 2 questions need answering: how well are guidelines followed in real-life practice and do patients benefit in the long-term?

In a new systematic review, Kamper et al. [9] tackle the first question in relation to first-contact care for patients with low back pain provided by family practice and emergency department physicians. (aka “usual medical care”) As the authors state, low back pain has major significance for the international pain community. It is the leading single cause of years lost to disability globally, [17] and there is good evidence for what constitutes best first-contact treatment. [6] The review selected best-quality studies of routine health care data to investigate whether first-contact physicians are putting back pain guidelines into practice (“usual care”).
