As often discussed in my research reviews, pain in lower back remains an enigma in modern day health care. It is a common, disabling, and costly condition that we know relatively little about in terms or pathoanatomical causes and effective treatments.This study was reported in the print and television media, so I felt it important to review here. As always, if you have any questions about this or any of my other reviews, please feel free to contact me.The goal of this large meta-analysis was to evaluate the effectiveness of exercise therapy in the treatment of low back pain in adults. Exercise therapy was intentionally defined in this study as a heterogeneous group of interventions from general physical fitness interventions to various types of stretching and aerobic exercise protocols. 61 published reports of completed, randomized controlled trials comparing an exercise intervention to placebo, no treatment or other conservative treatments were included in the analysis. Patients suffering acute ( 12 weeks) low back pain were included in the studies (most of the studies involved chronic patients).The trials evaluated provided the following insights: there is clear evidence that exercise therapy is at least as effective as other conservative therapies for chronic low back pain, despite conflicting evidence that it is any better
for acute pain in lower back, exercise are not more effective than other conservative therapies (note that exercise therapy is not the same as advice to stay active, which is currently a recommended, evidence-based intervention for low back pain)
there is some evidence to support a graded-activity exercise program for sub acute low back pain in occupational settings
