Return or no return--psychosocial factors related to sick leave in persons with musculoskeletal disorders: a prospective cohort study.

Purpose: The aim of this study was to compare psychosocial factors between healthy persons and sick-listed persons with musculoskeletal disorders (MSD); both groups with MSD 10 years ago.
Methods: This cohort study was prospective and 385 persons participated in a rehabilitation program 10 years ago, and 354 persons took part in the follow-up. Of these, 243 persons completed a questionnaire. Two groups were included in the study: a healthy group (not sick-listed) (n = 112) and a sick-listed group (n = 74). Psychosocial factors related to sick leave were compared between the groups.
Results: In the 10-year follow-up, the healthy group showed a significantly higher quality of life, more control over the working situation, better sense of coherence and unexpectedly more life events. There was no significant difference in social integration and emotional support between the groups.
Conclusions: Using the knowledge about the characteristics of the healthy group, adequate rehabilitation for every sick-listed person with a musculoskeletal disorder can be given and therefore facilitate the returning to work process. A multidimensional approach taking into account a person's physical condition and workplace related problems, as well as psychosocial factors, is of great importance for the person and for society.
