Cardiovascular risk factors and low-back pain in a long-term follow-up of industrial employees.
Atherosclerosis of the lumbar vessels has been suggested as a mechanism leading to low-back pain (LBP). We studied whether seven cardiovascular disease (CVD) risk factors predict LBP. ⋯ The study adds to the evidence supporting the atherosclerosis-LBP hypothesis particularly for men.

ReviewTrunk-strengthening exercises for chronic low back pain: a systematic review.
The objective of this systematic review was to determine the effect of lumbar spine-strengthening exercises on outcomes for people with chronic low back pain. ⋯ Trunk strengthening appears effective compared with no exercise. Increasing exercise intensity and adding motivation increase treatment effects. Trunk strengthening, compared with aerobics or McKenzie exercises, showed no clear benefit of strengthening. It is unclear whether observed benefits are due to tissue loading or movement repetition.

The purposes of this study were to investigate the association among measures of fear-avoidance beliefs, pain intensity, and lumbar flexion and to determine if changes in these measures were predictive of treatment outcome following physical therapy for acute low back pain. It was hypothesized that items of the Fear-Avoidance Beliefs Questionnaire would be correlated with concurrent measures of pain intensity and lumbar flexion. In addition, it was hypothesized that changes in fear-avoidance beliefs would be predictive of changes in self-report of pain intensity and disability. ⋯ These results suggest that fear-avoidance beliefs have a similar association with pain intensity, physical impairment, and disability for patients with acute and chronic low back pain. This study provides preliminary support for the use of the Fear-Avoidance Beliefs Questionnaire as an outcome measure for patients with acute low back pain.

The relative responsiveness of 3 different types of clinical outcome measures on chiropractic patients with low back pain.
The purpose of this study is to compare the responsiveness/sensitivity of 3 fundamentally different types of outcome measures in low back pain. ⋯ More research is needed in this area, and caution must be taken in choosing outcome measures for randomized clinical trials on low back pain.

Comparative Study
Effects of pelvic skeletal asymmetry on trunk movement: three-dimensional analysis in healthy individuals versus patients with mechanical low back pain.
Comparative analysis and correlational research design were used to investigate the association between anthropometry and biomechanical performance among asymptomatic subjects and patients with low back pain (LBP). ⋯ This study demonstrates objective differences in patterns of lumbar movement between asymptomatic subjects and patients with LBP. The study also demonstrates that subtle anatomic abnormality in the pelvis is associated with altered mechanics in the lumbar spine. We suggest that asymmetry of lumbar movement may be a better indicator of functional deficit than the absolute range of movement in LBP.
