ABSTRACT
One of the major requirements in preventing work related musculoskeletal injuries is to know precisely what strenuous exertion requirements are contained in a job. This requires improved job analysis tools which can accurately predict potentially harmful stresses to the musculoskeletal system. But to simply depict the level of stress at a joint, or in a muscle or tendon is not enough to motivate job changes. The stress levels must be evaluated, i.e. compared to a population's performance capacity or injury risk.
