In the past decade, controlled trials with rehabilitative interventions such as work hardening and exercise have been reported in the literature. Understanding these studies provides a framework from which rational rehabilitation programs can be structured. The literature supports active exercise programs using exercise-to-quota principles. Passive modalities and home exercise programs are less effective than are active supervised programs. © Williams & Wilkins 1997. All Rights Reserved.
