title: [Orthostatic work factor and its place in classification of work hardness].
abstract: The authors suggest percentage of work time in orthostatic posture as a basic indicator of orthostatic work factor. This indicator correlates with prevalence of varicose disease and is recommended for evaluation of work hardiness in units. The diagram presented characterizes a paradigm and serves as a point for quantitative evaluation of work hardiness in orthostatic posture.
