Summary
This study introduces the load-strain approach in occupational medicine and ergonomics, differentiating between work "load" and "strain." It provides a framework for assessing working conditions and making practical judgments.
Area of Science:
- Occupational Medicine
- Ergonomics
- Occupational Hygiene
Background:
- The terms "load" and "strain" lack clear distinction in occupational hygiene and WAO terminology.
- Occupational medicine and ergonomics have developed the "load-strain approach" since the 1970s.
Purpose of the Study:
- To outline the historical development and explain the "load-strain approach."
- To demonstrate the approach's significance for planning and executing ergonomic investigations.
- To recommend differentiating between the description, assessment, and judgment of working conditions.
Main Methods:
- Historical review of "load" and "strain" terminology.
- Derivation and presentation of the "load-strain approach" in simple and extended forms.
- Discussion of criteria and models for operationalizing strain and making pragmatic judgments.
Main Results:
- The "load-strain approach" offers a structured method for analyzing work conditions.
- Differentiation between description, assessment, and judgment is crucial for ergonomic investigations.
- Models for operationalizing strain and balancing scientific proof with practical decisions are presented.
Conclusions:
- The "load-strain approach" is significant for ergonomic investigations and assessing working conditions.
- A pragmatic judgment concept is proposed to reconcile scientific rigor with practical applicability.
- Clear differentiation of load and strain enhances occupational health assessments.
