A randomized prospective study of vocational outcome in rehabilitation of patients with non-specific musculoskeletal pain: a multidisciplinary approach to patients identified after 90 days of sick-leave.

This study was designed to evaluate the effectiveness of a multidisciplinary rehabilitation programme offered to a general population with 90 days of sick-leave due to non-specific musculoskeletal pain. The results concerning return to work and re-sick-listing during a follow-up period of five years were evaluated for Swedes and immigrants separately. Compared to a control group, the rehabilitation offer resulted in improved work stability after work return among the Swedes. The immigrants, as a group, did not benefit from the programme compared to the controls in primary care.
