Defining a systems framework for characterizing physical work demands with wearable sensors.

Area of Science:

• Occupational Health and Safety
• Ergonomics
• Human-Computer Interaction

Background:

• Measuring physical job demands is crucial for understanding worker health and safety.
• Traditional methods may not capture the evolving nature of modern work.
• Wearable motion sensors offer new possibilities for noninvasive, long-term monitoring.

Purpose of the Study:

• To present a framework for measuring physical work demands using advanced sensor technologies.
• To guide the integration of wearable sensors in research and practice for physical demand assessment.
• To adopt a systems-thinking perspective for understanding workplace challenges.

Main Methods:

• Literature review of current physical demand measurement techniques.
• Development of a framework extending the International Classification of Functioning (ICF) for technology application.
• Background on wearable motion sensing technologies (IMUs, heart rate, muscle activity).
• Definition of decision-making categories to guide measurement needs.

Main Results:

• A comprehensive framework for assessing physical work demands is proposed.
• The framework integrates wearable sensor data within a systems-level approach.
• It facilitates asking relevant questions about work demands at different scales.

Conclusions:

• The presented framework enables a systems approach to studying changing work demands.
• It guides the application of wearable motion sensors for assessing physical job demands.
• This approach supports research on the impact of work on worker safety, health, and well-being.
