Isokinetic measurement of trunk muscle strength in women with chronic low-back pain.
To investigate the relationships among chronic low-back pain and obesity, total spinal range of motion, and trunk muscle strength. The short-term impact of trunk muscle strengthening exercises on this condition was also examined. ⋯ Obesity and decrease in trunk muscle strength are important factors in chronic low-back pain, and a trunk muscle strengthening program will be helpful in reducing the pain.

Neck and low back pain are leading causes of morbidity and health care utilization. However, little is known about the characteristics that differentiate those who seek from those who do not seek health care for their pain. ⋯ Individuals seeking care for neck or back pain have worse health status than those who do not seek care. Patients consulting chiropractors alone report fewer comorbidities and are less limited in their activities than those consulting medical doctors.

Comparative Study
Disc herniation-related back pain impairs feed-forward control of paraspinal muscles.
A comparative study of lumbar paraspinal muscle reflexes during sudden upper limb loading in healthy control subjects and patients with sciatica. ⋯ The results provide evidence for impaired feed-forward control of lumbar muscles in patients with sciatica.

A population-based cross-sectional and 5-year prospective questionnaire study. ⋯ Having a sedentary job might have a protective or neutral effect in relation to low back pain, whereas having a heavy physical job constitutes a significant risk factor. Because of migration between exposure groups (the "healthy-worker" effect), longitudinal studies are necessary for investigating the associations between physical workload and low back pain.

A number of ergonomic, workplace and individual psychosocial factors and health behaviors have been associated with the onset, exacerbation and/or maintenance of low back pain (LBP). The functional impact of these factors may be influenced by how a worker approaches problems in general. The present study was conducted to determine whether problem-solving orientation was associated with physical and mental health outcomes in fully employed workers (soldiers) reporting a history of LBP in the past year. ⋯ Among those with a longer history of low-grade LBP, an avoidant approach to problem-solving was also associated with a steeper gradient of functional loss (three-way interaction; F(1,458)=4.58). These results suggest that the prolonged impact of LBP on daily function may be reduced by assisting affected workers to conceptualize LBP as a problem that can be overcome and using strategies that promote taking an active role in reducing risks for LBP. Secondary prevention efforts may be improved by addressing these factors.
