Functional restoration programs for low back pain: a systematic review.

BACKGROUND

In developed countries, chronic low back pain (LBP) is one the most common reasons for disability and work-time loss. Conventional treatments have not slowed the increasing prevalence of chronic LBP. Therefore, in a search for new solutions to the problem, functional restoration programs were developed.

OBJECTIVE

To synthesize the literature on the efficacy of functional restoration programs for LBP.

METHODS

We performed a systematic literature search of the MedLINE database using the keywords LBP, functional restoration, work-hardening program, exercise therapy, rehabilitation, aerobic, and cognitive behavioral therapy.

SYNTHESIS

The term "functional restoration" has been associated with a full-day multidisciplinary program lasting from 3 to 6 weeks. Results of most published controlled studies on the efficacy of functional restoration programs are positive regarding the return-to-work rate. Maintaining job status with the pre-injury employer is often best accomplished by the provision of suitable modified duties. Finally, results of functional restoration programs in terms of return-to-work rate probably depend strongly on the social security system of the country where the program was developed.
