The purpose of the study to evaluate implementing S-E-T Corporate in a number of Norwegian companies and to compare this intervention to other traditional physiotherapeutic interventions. The study lasted for 12 months and was initiated in March 2003. Participants in the intervention group (80 employees in 6 companies) training S-E-T obtained a significant improvement in functional ability and self reported physical health. In the control group (37 employees in 4 companies) there were no improvements in the functional ability and self reported health. There was no significant decrease in sick leave in either of the two groups but in some companies which had a high sick leave prior to project there were reductions in sick leave after implementing S-E-T. What seemed to be the “common factor” in the companies that did get a reduction in sick leave was encouraged company leadership and encouraged physiotherapist with a good S-E-T knowledge.
