The purpose of this study was to investigate the time dependent effects among factors affecting duration of work disability after compensated low-back pain. A postal survey involving 238 compensated workers at 39 companies was performed between January 5, 2004, and March 23, 2004. Cox proportional hazard regression analysis was used to model the effect of demographic, work-related, and injury f...

Short-term (<4 months) treatment with opioids provides modest relief of chronic low back pain, but only minimal improvement in function compared with placebo.

STUDY DESIGN A 3-year prospective cohort study among workers of 34 companies in the Netherlands. OBJECTIVES To investigate the relation between flexion and rotation of the trunk and lifting at work and the occurrence of low back pain. SUMMARY OF BACKGROUND DATA Previous studies on work-related physical risk factors for low back pain either lacked quantification of the physical load or did n...

The most frequently quoted epidemiological studies cite lifetime adult prevalence rates varying from50% to 80%, and point prevalence rates from15% to 30%.Yet even these statisticsmay underestimate the problem.A recent prospective studyof 154 reserve soldierswithno priorhistoryofbackpain found that64%of this lowrisk group developed at least moderate back pain over an 18 month period when queried...

In cases of low back pain, the goal is to detect serious problems and to prevent the pain from becoming chronic by promptly detecting risk factors. The authors lay out a simple, evidence-based approach to low back pain.

CONTEXT Hip function has been proposed to be related to low back pain (LBP) because of the anatomical proximity of the hip and lumbopelvic region. To date, findings have been inconclusive, possibly because the samples studied were heterogeneous. Sub-grouping samples based on characteristics such as activity demand, LBP classification, and sex might clarify research findings. OBJECTIVE To desc...

Trunk extensors and flexors muscles imbalance is strong indication of the etiology of low back pain. The aim of the present study was to verify the effect of Pilates© method upon trunk flexors and extensors isokinetic function. To do so, we selected 20 volunteers (16 women 34.06 ± 7.21 yrs; 4 men 33.5 ± 6.68 yrs) capable to perform the intermediate-advanced level of Pilates© method (25 sessions...
