Clinical TrialThe effects of a three-week use of lumbosacral orthoses on trunk muscle activity and on the muscular response to trunk perturbations.
The effects of lumbosacral orthoses (LSOs) on neuromuscular control of the trunk are not known. There is a concern that wearing LSOs for a long period may adversely alter muscle control, making individuals more susceptible to injury if they discontinue wearing the LSOs. The purpose of this study was to document neuromuscular changes in healthy subjects during a 3-week period while they regularly wore a LSO. ⋯ The LSO increased trunk stiffness and resulted in a greater number of agonist muscles shutting-off in response to a quick force release. However, these effects did not result in detrimental changes to the neuromuscular function of trunk muscles after 3 weeks of wearing a LSO 3 hours a day by healthy subjects.

The current criterion standard for zygapophyseal (facet) joint pain diagnosis is placebo-controlled triple comparative local anesthetic facet joint or medial branch blocks. Single photon emission computerized tomography (SPECT) scanning is a less invasive modality that has been widely used in patients with spinal pain for the diagnosis of facet joint arthritis. Previous studies have shown that SPECT results correlate well with response to facet joints steroid injections. ⋯ In a hospital-wide population with spinal pain, there is a 42.88% prevalence of increased uptake in the facet joint on SPECT. The incidence increases significantly with advancing age. SPECT can play a role in investigating patients with spinal pain.

Obesity and recovery from low back pain: a prospective study to investigate the effect of body mass index on recovery from low back pain.
We describe a prospective cohort study to investigate any association between recovery from low back pain and body mass index (BMI) in patients with low back pain undergoing physiotherapy. ⋯ This study demonstrates that BMI does not influence the overall recovery from low back pain in patients undergoing physiotherapy treatment.

Case ReportsImportance of fear-avoidance behavior in chronic non-specific low back pain.
International classification of Functioning, Disability and Health has adapted a biopsychosocial model for management of chronic low back pain patient (CLBP). The influence of psychological factors seems to be important in the transition from acute to chronic low back pain (> 3 months). In particular, pain-related fear and pain catastrophizing are believed to be important factors for disability. ⋯ After a few weekly therapeutic sessions of CBT, significant changes were seen in all outcome measures. It has been concluded that probably, by using specific biopsychosocial training, positive results in fear avoidance behavior can be achieved. Hence the psychotherapeutic management approach is considered as a useful economical tool in low back pain.

the role of immune response and proinflammatory cytokines in the pathogenesis of chronic pain has been of growing interest. In order to evaluate whether there is any association between disc herniation and elevated cytokine levels, we measured cytokine levels in patients with chronic low back pain and in healthy subjects. ⋯ The patients with chronic low back pain due to disc herniation presented higher levels of TNF-alpha and IL-6, but not of IL-1 or sTNF-R.
