Input: After screening 1808 abstracts, and the references of 65 reviews, we found only seven relevant studies (1050 patients) that met our inclusion criteria. None of these were considered, methodologically, a high quality randomized controlled trial. Four of the included RCTs on fibromyalgia were graded low quality and suggest no quantifiable benefits. The three included RCTs on widespread musculoskeletal pain showed that based on limited evidence, overall, no evidence of efficacy was observed. However, behavioral treatment and stress management appear to be important components. Education combined with physical training showed some positive effects in long term follow up. We conclude that there appears to be little scientific evidence for the effectiveness of multidisciplinary rehabilitation for these musculoskeletal disorders. However, multidisciplinary rehabilitation is a commonly used intervention for chronic musculoskeletal disorders, which cause much personal suffering and substantial economic loss to the society. There is a need for high quality trials in this field.
Output:

The main purpose of this systematic review was to determine the effectiveness of multidisciplinary rehabilitation for fibromyalgia and wide spread musculoskeletal pain among working age adults. Patients included in the controlled trials in this review ranged in age from 18-65 years. Seven studies, with 1050 patients were included. The effectiveness of multidisciplinary rehabilitation was graded limited, showing no quantifiable benefit for both fibromyalgia and widespread musculoskeletal pain.
