Review Meta AnalysisOsteopathic manipulative treatment for low back pain: a systematic review and meta-analysis of randomized controlled trials.
Osteopathic manipulative treatment (OMT) is a distinctive modality commonly used by osteopathic physicians to complement their conventional treatment of musculoskeletal disorders. Previous reviews and meta-analyses of spinal manipulation for low back pain have not specifically addressed OMT and generally have focused on spinal manipulation as an alternative to conventional treatment. The purpose of this study was to assess the efficacy of OMT as a complementary treatment for low back pain. ⋯ OMT significantly reduces low back pain. The level of pain reduction is greater than expected from placebo effects alone and persists for at least three months. Additional research is warranted to elucidate mechanistically how OMT exerts its effects, to determine if OMT benefits are long lasting, and to assess the cost-effectiveness of OMT as a complementary treatment for low back pain.

Comparative Study
Discographic, MRI and psychosocial determinants of low back pain disability and remission: a prospective study in subjects with benign persistent back pain.
A range of morphologic and psychosocial variables has been suggested as risk factors for serious low back pain (LBP) illness. Although the relative contributions of structural and psychosocial variables are intensely debated, the validity of differing hypotheses has proven difficult to test because the incidence of serious disabling LBP illness is low in healthy subjects. These factors dictate the requirement for large sample sizes, extensive structural imaging and extended longitudinal study. Previous studies included either small cohorts with intensive imaging testing or large population studies that do not establish a detailed morphologic baseline. ⋯ The development of serious LBP disability in a cohort of subjects with both structural and psychosocial risk factors was strongly predicted by baseline psychosocial variables. Structural variables on both MRI and discography testing at baseline had only weak association with back pain episodes and no association with disability or future medical care.

The way people with chronic low back pain think about pain can affect the way they move. This case report concerns a patient with chronic disabling low back pain who underwent functional magnetic resonance imaging scans during performance of a voluntary trunk muscle task under three conditions: directly after training in the task and, after one week of practice, before and after a 2.5 hour pain physiology education session. ⋯ The results suggest that pain physiology education markedly altered brain activity during performance of the task. The data offer a possible mechanism for difficulty in acquisition of trunk muscle training in people with pain and suggest that the change in activity associated with education may reflect reduced threat value of the task.

Comparative Study
The differential role of pain, work characteristics and pain-related fear in explaining back pain and sick leave in occupational settings.
This cross-sectional questionnaire study investigated the role of pain (pain severity, radiating pain), work characteristics (physical workload, job stressors, job satisfaction), negative affect and pain-related fear in accounting for low back pain (LBP) and sick leave (SL) in 1294 employees from 10 companies in Belgium and the Netherlands. An increased risk for short-term LBP (1-30 days during the last year) was observed for workers reporting high physical workload (OR=2.39), high task exertion (OR=1.63) and high negative affect (OR=1.03). For prolonged LBP (>30 days during the last year) severe pain (OR=13.03), radiating pain (OR=2.37) and fear of work-related activities (OR=3.17) were significant risk factors. ⋯ A lack of co-worker support reduced the risk of long-term SL (OR=0.27). These results suggest that physical load factors are relatively more important in the process leading to short-term LBP and short-term SL, whereas job stressors, severe pain, radiation, and pain-related fear are more important in determining the further course and maintenance of the inability to work. The potential implications of these findings for primary and secondary prevention, and occupational rehabilitation are discussed.

Randomized Controlled Trial Clinical Trial
Fear of movement/(re)injury in chronic low back pain: education or exposure in vivo as mediator to fear reduction?
Clinical research of graded exposure in vivo with behavioral experiments in patients with chronic low back pain who reported fear of movement/(re)injury shows abrupt changes in self-reported pain-related fears and cognitions. The abrupt changes are more characteristics of insight learning rather than the usual gradual progression of trial and error learning. The educational session at the start of the exposure might have contributed to this insight. ⋯ Performance of relevant daily activities, however, were not affected by the educational session and improved significantly only in the exposure in vivo condition. All improvements remained at half-year follow-up only in patients receiving the exposure in vivo. These patients also reported a significant decrease in pain intensity at follow-up.
