First PEROSH report:

The first report focuses on how to appropriately assess occupational sedentary behavior. As despite a growing amount of literature on sedentary behavior and the advances in wearable technology that allows assessment of sedentary behavior, there are no current standard procedures and recommendations available for assessing sedentary behavior using technical measurements.

Therefore this PEROSH report aims to provide recommendations for how to measure and interpret the output, to appropriately assess occupational sedentary behavior using current technical measurement systems. It supplies a framework of important criteria for the use of potential future equipment to assess occupational sedentary behavior.

The report mainly highlights both minimal systems to be used in the field by practitioners and scientists on large populations, and detailed measurement systems to precisely assess important details about occupational sedentary behavior. Basic systems that can approximate occupational sedentary behavior with some important considerations in mind are also covered.

Second PEROSH report:
The second report focuses on; how to measure and what to consider in the assessment of work with elevated arms. This is an often mentioned risk factor for developing musculoskeletal disorders of the neck and upper limbs, but it has often been described and assessed with ambiguous or unprecise definitions which complicate comparing different studies.

Technical measurements that allow assessment of work with elevated arms are getting more and more important. The relevance of technical measurements will depend on the goal of examination, including the study-population, choosing the correct method to estimate the exposure in the study-population and measuring relevant parameters for analysis with regards to the outcome examined.

Therefore this PEROSH report aims to provide recommendations for measuring and interpreting work with elevated arms using various measurement techniques and strategies.


During the PREMUS 2016 conference in Toronto, the PEROSH group members were responsible for hosting a symposium with the title: “Technical field measurements of sedentary work and occupational physical
demands: A PEROSH-initiative”. The symposium was divided into two parts, with 6 presentations as follows:

Validation and Calibration of Questionnaire-based Sitting Time: An Accelerometer-based Study among Blue Collar Workers by Holtermann, Andreas

Classification of wearables for occupational physical activity measurements by Weber, Britta

Practical objective measurements for sedentary time and body postures – utilizing Excel and iOS by Forsman, Mikael

How to objectively measure lifting burden in the field on many participants? Results and experience from use of pressure-measurement insoles in a field study by Koch, Markus

Development of a CTS-risk assessment method for manual working processes based on technical measurements by Hoehne-Hueckstaedt, Ulrike

Influence of task proportion errors on the effectiveness of task-based job exposure modeling by Mathiassen, Svend Erik

Developed by one of the PEROSH group members, ErgoArmMeter is a professional inclinometer Application for iOS devices. It measures and records arm elevation during work. This is a great example of how technical measurements are getting more readily accessible and feasible for common practitioners and scientists in the field using the inertial sensors of common smartphones.

Safe Work Australia’s report on sedentary behavior at work:

We would also like to direct attention to the very recent report from Safe Work Australia authored by Professor Leon Straker, Doctor Pieter Coenen, Professor David Dunstan, Doctor Nicholas Gilson and Doctor Genevieve Healy.

The report is primarily focused on the Australian workforce, but is also a comprehensive look into the current knowledge on occupational sedentary behavior internationally. This report complements the work being done by this PEROSH group and is a recommended read for anyone interested in sedentary behavior.
