Review and analysis of data from two U.S. national surveys in 2002.
To examine the prevalence of back pain and physician visits for back pain in the United States.
National data on the prevalence of back pain become available only intermittently.
We summarized published data from the 2002 National Health Interview Survey (NHIS) on the prevalence of back pain and compared it with earlier surveys. We also analyzed the 2002 National Ambulatory Medical Care Survey (NAMCS) to determine physician visit rates for back pain.
In the 2002 NHIS, there were 31,044 adult respondents. Low back pain lasting at least a whole day in the past 3 months was reported by 26.4% of respondents, and neck pain was reported by 13.8%. Among racial groups, American Indians and Alaska Natives had the highest prevalence of low back pain, and Asian Americans had the lowest. Prevalence generally declined with greater levels of education and increasing income. Prevalence estimates were consistent with those from previous surveys, although methodologic differences limited comparisons. NAMCS data suggested that the proportion of all physician visits attributable to low back pain (2.3% in 2002) has changed little since the early 1990s.
About one fourth of U.S. adults report low back pain in the past 3 months; the proportion of physician visits attributed to back pain has changed little in the past decade.

    ABSTRACT: In degenerative adult spinal deformity (ASD), sagittal malalignment and rotatory subluxation (RS) correlate with clinical symptomatology. RS is defined as axial rotation with lateral listhesis. Stereoradiography, recently developed for medical applications, provides full-body standing radiographs and 3D reconstruction of the spine, with low radiation dose. 3D stereoradiography improves analysis of RS and of its relations with transverse plane and spinopelvic parameters and clinical impact. One hundred and thirty adults with lumbar ASD and full-spine EOS(®) radiographs (EOS Imaging, Paris, France) were included. Spinopelvic sagittal parameters and lateral listhesis in the coronal plane were measured. The transverse plane study parameters were: apical axial vertebral rotation (apex AVR), axial intervertebral rotation (AIR) and torsion index (TI). Two groups were compared: with RS (lateral listhesis>5mm) and without RS (without lateral listhesis exceeding 5mm: non-RS). Correlations between radiologic and clinical data were assessed. RS patients were significantly older, with larger Cobb angle (37.4° vs. 26.6°, P=0.0001), more severe sagittal deformity, and greater apex AVR and TI (respectively: 22.9° vs. 11.3°, P<0.001; and 41.0° vs. 19.9°, P<0.001). Ten percent of patients had AIR>10° without visible RS on 2D radiographs. RS patients reported significantly more frequent low back pain and radiculalgia. In this EOS(®) study, ASD patients with RS had greater coronal curvature and sagittal and transverse deformity, as well as greater pain. Further transverse plane analysis could allow earlier diagnosis and prognosis to guide management. 4, retrospective study. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    • "Osteoarthritis (OA) can affect any joint in the body, but the medial tibiofemoral compartment is most commonly affected, and it was estimated to impact approximately 21 million Americans [2]. Low back pain (LBP) is another very prevalent problem, affecting over 30 million Americans [3] [4] [5], with the lifetime prevalence estimated at 75–85% [6]. "

    ABSTRACT: The effect of joint pathologies, such as unilateral knee osteoarthritis (UKOA) or low back pain (LBP), on bilateral gait symmetry has gained increased attention during the past decade. This study is the first to compare gait patterns between patients with UKOA and LBP in combination and with UKOA only. Temporal, kinematic, and kinetic variables were measured bilaterally during gait stance phase in 31 subjects with UKOA and LBP (Group I) and 11 subjects with only UKOA (Group II). Group I patients exhibited less hip rotation in the affected limb (A) than in the nonaffected (NA) limb during walking in contrast to Group II patients. Group I patients had minimal bilateral differences in hip abduction and flexion, but Group II patients displayed significantly larger values in the NA limb compared to the A limb for both parameters. Hip flexion patterns were significantly different between Groups I and II. Subjects in both groups adapted gait patterns that minimized vertical ground reaction force, knee flexion motion, and stance time on the UKOA affected limb. The distinct kinematic gait patterns that were revealed in this study may provide clinical value for assessment of patients with UKOA in conjunction with LBP.

    • "Low back pain (LBP) is a very common disorder [1], with approximately 84% of adults experiencing an episode of LBP at some point during their lifetimes [2] and variable recurrence rates (5% to 60%) [3]. LBP, identified as the leading disability contributor [4], may result in a reduced level of physical capacity [5]–[9], negative psychological effects [10]–[17], and reduction in the quality of life; as such, LBP is one of the most common reasons that patients opt to undergo health care [18], [19]. In the United States, back pain-related lost productive work time in workers aged between 40 and 65 years costs employers an estimated $7.40 billion per year [20]; and an estimated $50 billion is spent annually on LBP treatments [21].

    ABSTRACT: Background Trials on sling exercise (SE), commonly performed to manage chronic low back pain (LBP), yield conflicting results. This study aimed to review the effects of SE on chronic LBP. Methods The randomized controlled trials comparing SE with other treatments or no treatment, published up to August 2013, were identified by electronic searches. Primary outcomes were pain, function, and return to work. The weighted mean difference (WMD) and 95% confidence interval (CI) were calculated, using a random-effects model. Results Risk of bias was rated as high in 9 included trials, where some important quality components such as blinding were absent and sample sizes were generally small. We found no clinically relevant differences in pain or function between SE and other forms of exercise, traditional Chinese medical therapy, or in addition to acupuncture. Based on two trials, SE was more effective than thermomagnetic therapy at reducing pain (short-term: WMD –13.90, 95% CI –22.19 to –5.62; long-term: WMD –26.20, 95% CI –31.32 to –21.08) and improving function (short-term: WMD –10.54, 95% CI –14.32 to –6.75; long-term: WMD –25.75, 95% CI –30.79 to –20.71). In one trial we found statistically significant differences between SE and physical agents combined with drug therapy (meloxicam combined with eperisone hydrochloride) but of borderline clinical relevance for pain (short-term: WMD –15.00, 95% CI –19.64 to −10.36) and function (short-term: WMD −10.00; 95% CI −13.70 to −6.30). There was substantial heterogeneity among the two trials comparing SE and thermomagnetic therapy; both these trials and the trial comparing SE with physical agents combined with drug therapy had serious methodological limitations. Interpretation Based on limited evidence from 2 trials, SE was more effective for LBP than thermomagnetic therapy. Clinically relevant differences in effects between SE and other forms of exercise, physical agents combined with drug therapy, traditional Chinese medical therapy, or in addition to acupuncture could not be found. More high-quality randomized trials on the topic are warranted.
