Low back pain (LBP) is currently the most prevalent and costly musculoskeletal problem in modern societies. Screening instruments for the identification of prognostic factors in LBP may help to identify patients with an unfavourable outcome. In this systematic review screening instruments published between 1970 and 2007 were identified by a literature search. ⋯ The strongest predictors for "work status" were psychosocial and occupational structures, whereas for "functional limitation" and "pain" psychological structures were dominating. Psychological and occupational factors show a high reliability for the prognosis of patients with LBP. Screening instruments for the identification of prognostic factors in patients with LBP should include these factors as a minimum core set.

Opioid therapy for nonspecific low back pain and the outcome of chronic work loss.
Outcomes of opioid therapy for noncancer pain remain to be more fully explored. Loss of work is among these outcomes. Especially when work loss becomes "chronic" (persists >or=90 days), it has profound psycho-social repercussions that compound suffering of those already in pain. ⋯ Our analysis was not designed to ascertain antecedent causes, or why chronic work loss occurred in the first place. Rather, we focused on an ensuing consequence of opioid therapy, i.e., the outcome of chronic work loss, which occurred far removed in time (>or=90 days) after the worker's recorded date of back injury. The strong associations observed suggest that for most workers opioid therapy did not arrest the cycle of work loss and pain.

The history of the use of electrical stimulation for pain is a cavalcade of research and innovation of many great scholars, scientists, and physicians over centuries that continues up to the present day. The legacy of this philosophy, research, and innovation is the field of neuromodulation for pain control. Today, patients with chronic pain from damage to the nervous system and chronic pain of the extremities, the axial low back, and neck, the face, and the viscera, all derive benefit from these early pioneers that have led to the expanding field of neuromodulation ... "on the shoulders of giants." We present here a history of the understandings of pain from the ancients to the present, which has led to our understandings of the use of electricity to cure disease and release patients from their suffering, generating the new, exciting, and expanding field of neuromodulation.

Randomized Controlled TrialPreventing progression to chronicity in first onset, subacute low back pain: an exploratory study.
To evaluate the effects of a behavioral medicine intervention, relative to an attention control, in preventing chronic pain and disability in patients with first-onset, subacute low back pain (LBP) with limitations in work-role function. ⋯ Early intervention using a behavioral medicine rehabilitation approach may enhance recovery and reduce chronic pain and disability in patients with first-onset, subacute LBP. Effects are stronger for participants attending all 4 sessions and the follow-up assessment.

Prolonged standing has been associated with the onset of low back pain symptoms in working populations. So far, it is unknown how individuals with chronic low back pain (CLBP) behave during prolonged unconstrained standing (PS). The aim of the present study was to analyze the control of posture by subjects with CLBP during PS in comparison to matched healthy adults. ⋯ The present study provides additional evidence that individuals with CLBP might have altered sensory-motor function. Their inability to generate responses similar to those of healthy subjects during prolonged standing may contribute to CLBP persistence or an increase risk of recurrent back pain episodes. Moreover, quantification of postural changes during prolonged standing could be useful to identify CLBP subjects prone to postural control deficits.
