Interventions for chronic low back pain (CLBP) often attempt to modify patients' levels of catastrophizing, their fear-avoidance beliefs, and their appraisals of control. Presumably, these interventions are based on the notion that changes in these cognitive factors are related to changes in measures of adjustment. The aim of the present study was to explore whether changes on these cognitive factors were related to changes in CLBP and disability. ⋯ The study found that changes in the cognitive factors were not significantly associated with changes in pain intensity. In contrast, reductions in fear-avoidance beliefs about work and physical activity, as well as increased perceptions of control over pain were uniquely related to reductions in disability, even after controlling for reductions in pain intensity, age and sex. The final model explained 71% of the variance in reductions in disability.

Published studies of intradiscal thermal annuloplasty (IDTA) have shown at most 50% pain relief as an improved outcome with little focus on functional improvement in the treatment of discogenic pain. Previous studies have used a number of criteria for patient selection including low back pain unresponsive to conservative care, no compressive radiculopathy, positive provocative discography and absence of previous surgery at the same symptomatic level. The purpose of present study is to examine the hypothesis that additional inclusion criteria for patient selection such as disc height, absence of degenerative disc disease (DDD) in untreated discs, absence of herniated nucleus pulposus or lumbar canal stenosis may improve the outcome of treatment. ⋯ We found dramatic improvement of pain scores and ADLs following IDTA when strict patient selection was applied. We believe that IDTA is an effective, minimally invasive treatment for discogenic pain in properly selected patients.

Back pain and disability after lumbar laminectomy: is there a relationship to muscle retraction?
Preliminary studies have suggested that prolonged retraction of the paraspinal muscle during spinal surgery may produce ischemic damage. We report the continuous measurement of intramuscular pressure (IMP) during decompressive lumbar laminectomy and its relationship to subsequent back pain and disability. ⋯ The McCulloch retractor generates a higher IMP than the Norfolk and Norwich retractor. However, postoperative improvement in VAS, ODI, and SF-36 scores in these patients was associated with a shorter duration of muscle retraction and not the degree of IMP or IPP generated. In this respect, periodic relaxation of the paraspinal muscle retractors during surgery to allow muscle perfusion may help to reduce postoperative back pain and disability.

Randomized Controlled Trial Clinical Trial
Acupuncture for low back pain in pregnancy--a prospective, quasi-randomised, controlled study.
This study was undertaken to investigate the effects of acupuncture in low back and pelvic pain during pregnancy under real life conditions, as compared with patients undergoing conventional treatment alone. A total of 61 conventionally treated pregnant women were allocated randomly into two groups to be treated or not by acupuncture. Twenty-seven patients formed the study group and 34 the control group. ⋯ The capacity to perform general activities, to work and to walk was improved significantly more in the study group than in the control group (P < 0.05). The use of paracetamol was lower in the acupuncture group (P < 0.01). These results indicate that acupuncture seems to alleviate low back and pelvic pain during pregnancy, as well as to increase the capacity for some physical activities and to diminish the need for drugs, which is a great advantage during this period.

Comparative StudyA school-based survey of recurrent non-specific low-back pain prevalence and consequences in children.
The aim of this investigation was to provide evidence of the prevalence and consequences of recurrent low-back pain in children from Northwest England. A cross-sectional survey was conducted involving a standardized questionnaire with established reliability and validity. A cross-sectional sample of 500 boys (n = 249) and girls (n = 251) aged between 10 and 16 years participated in the study. ⋯ It was concluded that low-back pain is a common complaint during childhood, although most cases are acute episodes that represent little health consequence. In contrast, some children experience recurrent low-back pain that can lead to disabling consequences. Future research should focus on recurrent low-back pain cases since they often led to disabling consequences.
