Work hardening and work conditioning interventions: do they affect disability?

Division of Physical Therapy, School of Health Related Professions, University of Alabama at Birmingham 35294-1270.

The purpose of this article is to review the research on the effectiveness of work hardening and work conditioning programs. Twelve studies of work hardening and work conditioning programs in the United States and abroad were reviewed. One study produced convincing evidence in a randomized study that a work conditioning program was useful in producing a higher percentage of return to work and an earlier return to work in a group of patients off work for at least 2 months. Another study demonstrated that a work hardening program increased the rate of return to work by 52% in patients off work for greater than 4 months. Most of the other studies reviewed suggested positive results, but more carefully documented, randomized, and controlled studies are needed to support the efficacy of these programs and to determine the optimum and most cost-effective work hardening and work conditioning interventions.
