Abstract
Musculoskeletal disorders are still a major problem in daily occupational life. Despite the high incidence rates and important consequences for employees, employers and society, efficient preventive strategies seem to fail in efficiency. The reason may be found in approaching the issue via the classic post-factum analysis. The preventive measures are almost not implemented because of the low predictability to be injured which affects the awareness of the problem and the low identification with the improvement proposals. MSD belong to the cumulative diseases which require and anticipating strategy based on early detection of pre-indicating symptoms.
