title: Practical aspects of identifying and correcting worksite stress in post-infarction patients returning to work.
abstract: The authors propose a dynamic 'man-work system' model, centered around the bodily strain, which is determined jointly by the momentary efficiency of the organism and the sum of stresses acting at a given point of time, i.e. integrated along various durations. With regard to stresses, they call attention to the heuristic significance of a separate subgroup, that of physiological stresses and also to the necessity of the distinction of a physiological subclass in the class of information stresses. The 'man-work system' is completed by positive and negative feedback from the strain and the components of efficiency, thereby providing the basis of successful or unsuccessful adaptation of the organism to the short- and long-term challenges. The authors are of the opinion that the system offers a sounder foundation for rehabilitative as well as preventive cardiology.
