Controlled Clinical Trial
Contribution of nonspinal comorbidity to low back pain outcomes.
To determine the involvement of comorbidity to outcomes in a cohort of acute mechanical low back pain patients. ⋯ Significant ORs were barely greater than 1.00 and were likely the result of the large sample size. The clinical course for comorbid patients, who may seem more complicated at the start of treatment, is just as favorable.

Chronic low back pain (CLBP) is a common and debilitating problem in older adults. Little exists in the literature about primary care physicians' (PCPs') knowledge of and confidence in managing this problem. A self-administered survey was mailed to PCPs in western Pennsylvania to measure knowledge of the evaluation and treatment of common contributors to CLBP in older adults, confidence in diagnosing these contributors through physical examination, and the association between confidence levels and knowledge. ⋯ There was no relationship between knowledge scores and confidence ratings (P > .05 for all comparisons). The results point to a need for more PCP education about CLBP in older adults. It also suggests that accurate needs assessment should not rely on physician confidence ratings alone.

To evaluate reliability, validity and responsiveness of the Fear-Avoidance Beliefs Questionnaire (FABQ) for use in Norwegian patients with low back pain. ⋯ The Norwegian FABQ version had acceptable factor structure, internal consistency, test-retest reliability and construct validity. The responsiveness of the FABQ-Work was low, and for the FABQ-PA moderate, in the acute sample.

This preliminary cross-sectional study was undertaken to determine if there were measurable relationships between posture, back muscle endurance and low back pain (LBP) in industrial workers with a reported history of flexion strain injury and flexion pain provocation. Clinical reports state that subjects with flexion pain disorders of the lumbar spine commonly adopt passive flexed postures such as slump sitting and present with associated dysfunction of the spinal postural stabilising musculature. However, to date there is little empirical evidence to support that patients with back pain, posture their spines differently than pain-free subjects. ⋯ Correlations between increased time spent sitting, physical inactivity and poorer back muscle endurance were also identified. There were no significant differences found between the groups for the standing and lifting posture measures. These preliminary results support that a relationship may exist between flexed spinal postures, reduced back muscle endurance, physical inactivity and LBP in subjects with a history of flexion injury and pain.

Comparative Study
Interrelationships among pain, disability, and psychological factors in young Korean conscripts with lumbar disc herniation.
The aim of this study was to compare the psychological factors between young Korean conscripts with lumbar disc herniation (LDH) and healthy controls and to evaluate the interrelationships among pain, disability, and psychological factors in LDH conscripts. The subjects consisted of 56 young conscripts with LDH and 76 controls. All subjects completed Beck's Depression Inventory and Spielberger's State-Trait Anxiety Inventory. ⋯ Pain intensity and state anxiety significantly contributed to the functional disability in the LDH conscripts. This study suggests that LDH conscripts have some psychological problems, such as depression and anxiety, in comparison to healthy controls. Furthermore, the pain intensity and state anxiety predict the functional disability in LDH conscripts.
