Case Reports
Physical therapist management of a patient with acute low back pain and elevated fear-avoidance beliefs.
Elevated fear-avoidance beliefs are believed to be a precursor of chronic disability, yet effective intervention options have not been described in the literature. The purpose of this case report is to describe physical therapist management of a patient with acute low back pain and elevated fear-avoidance beliefs. ⋯ Disability and fear-avoidance beliefs improved following a fear-avoidance-based physical therapy intervention. Research is warranted to investigate the effectiveness of this approach.

Treatment of herniated lumbar disc by intradiscal and intraforaminal oxygen-ozone (O2-O3) injection.
We report our experience between May 1996 and May 2003 with 2200 patients affected by low back pain or sciatica due to herniated disk treated by intradiscal and intraforaminal oxygen-ozone injection. The patients received medical and physical therapy before treatment for at least 2 months; the patients with conus-cauda syndrome and hyperalgesic sciatica were excluded. We never performed discography before the treatment that was performed under CT guidance or fluoroscopy. CT provided monitoring of gas distribution in the disk and epidural space. ⋯ No side effects were recorded at short and long-term follow-up. Clinical results were evaluated with the modified McNab method showing an 80% success rate and 20% failure rate in 1750 patients followed up to 6 months while the success rate dropped down at 75% and failure increased at 25% in 1400 followed up to 18 months. CT showed reduction in the size of the herniated disk in only 63% of the followed patients (420 patients). The failure has been mostly related to: calcified herniated disk; spinal canal stenosis; recurrent herniated disk with epidural fibrosis; small descending herniated disk at the level of the lateral recess.

Effects of low back pain on the relationship between the movements of the lumbar spine and hip.
Previous research had examined the effects of back pain on spinal movements, but information concerning movement coordination between the lumbar spine and hips was limited. The purpose of this study was to examine the effects of back pain and limitation in straight leg raise on the relationship between the movements of the lumbar spine and hip. An electromagnetic tracking system was employed to measure the movements of these joints in asymptomatic subjects (n = 20), and back pain subjects with (n = 24) and without (n = 17) limitation in straight leg raise. ⋯ Cross-correlation analysis showed that there were changes in the strength of correlation and the time lag between lumbar spine and hip motions in normal and back pain subjects. In addition, back pain and limitation in straight leg raise were found to cause significant increases in the time required to complete the trunk movements. It was concluded that clinical assessment and treatment planning should take into account of the effects of back pain on the relationship between spine and hip movements.

Randomized Controlled Trial Clinical Trial
Catastrophizing and internal pain control as mediators of outcome in the multidisciplinary treatment of chronic low back pain.
The aim of the present study was to examine (a) whether a cognitive-behavioral treatment (differentially) affects pain coping and cognition; and (b) whether changes in pain coping and cognition during treatment mediate treatment outcome. Participants in this randomized clinical trial were 148 patients with chronic low back pain attending a multidisciplinary treatment program consisting of operant-behavioral treatment plus cognitive coping skills training (N = 59) or group discussion (N = 58) or allocated to a waiting list control condition (N = 31). ⋯ Changes in catastrophizing and to a lesser degree in internal pain control mediated the reduction in level of depression and pain behavior following treatment. The use of behavioral and cognitive interventions aimed at decreasing catastrophizing thoughts about the consequences of pain and promoting internal expectations of pain control possibly constitute an important avenue of change irrespective of the type of treatment.

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.
