Randomized Controlled Trial Multicenter Study Clinical Trial
Efficiency and costs of medical exercise therapy, conventional physiotherapy, and self-exercise in patients with chronic low back pain. A pragmatic, randomized, single-blinded, controlled trial with 1-year follow-up.
A multicenter, randomized, single-blinded controlled trial with 1-year follow-up. ⋯ The efficiency of medical exercise therapy and conventional physiotherapy is shown. Leaving patients with chronic low back pain untampered poses a risk of worsening the disability, resulting in longer periods of sick leave.

Comparative Study Clinical Trial Controlled Clinical Trial
Five-year follow-up study of a controlled clinical trial using light mobilization and an informative approach to low back pain.
A controlled clinical trial. ⋯ This study indicates that subchronic low back pain may be managed successfully with an approach that includes clinical examination combined with information for patients about the nature of the problem, provided in a manner designed to reduce fear and give them reason to resume light activity.

Randomized Controlled Trial Clinical Trial
The reduction of chronic nonspecific low back pain through the control of early morning lumbar flexion. A randomized controlled trial.
Eighteen-month, randomized controlled trial with partial crossover. ⋯ Controlling lumbar flexion in the early morning is a form of self-care with potential for reducing pain and costs associated with chronic, nonspecific low back pain.

A study in genetic epidemiology of disc degeneration, based on lifetime exposure data, findings on magnetic resonance imaging, and genotyping of intragenic markers. ⋯ Specific vitamin D receptor alleles were associated with intervertebral disc degeneration as measured by T2-weighted signal intensity, demonstrating for the first time, the existence of genetic susceptibility to this progressive, age-related degenerative process.

Multicenter Study
Lumbar olisthesis and lower back symptoms in elderly white women. The Study of Osteoporotic Fractures.
A Cross-sectional study. ⋯ Anterolisthesis of 3 mm or more in the lower lumbar spine is relatively common among elderly women but is not correlated with back problems. Retrolisthesis at L3-L4 is associated with increased back pain and impaired back function.
