Is there a role for exercise in the treatment of patients with low back pain?

A paucity of information exists concerning the exact role of exercise in the management of low back pain. Few controlled clinical studies exist, and the selection of an exercise program is often relegated to traditional or empiric regimens. Aerobic conditioning exercises appear to offer the greatest benefit for all types of patients with back problems, although the value of these exercises is often overstated. Indirect evidence can be found for strengthening exercises that treat physical incapacity. No information is available to substantiate effects on pain relief. Comprehensive electromyographic studies, biomechanical analyses, and controlled clinical studies are needed to validate the role of exercises in the treatment of patients with back pain.
