Musculoskeletal Strain Assessment Study

Working conditions can often lead to the physical strain of employees resulting in the manifestation of musculoskeletal diseases. The aim of the Musceloskeletal Strain Assessment Study is to investigate the activities that possibly contribute to the musculoskeletal strain of the employees by identifying specific burden parameters and propose appropriate measures to reduce this strain as the case may be. 


As implementation methods, the following are used: 

  • subjective reports: use of questionnaires and interviews of employees 
  • observation methods: systematic monitoring of working conditions by an observer and completion of individual data in a special form 
  • direct measurements: use of sensors and instruments such as dynamometers, electronic goniometers, accelerometers, electromyographs and other detection devices that are connected directly to the worker’s body and take measurements during his work 


The study is based on 6 phases: 

  1. Defining a sample and collecting required data Analysis of tasks into activities
  2. Completion of respective forms – Observation / Interviews 
  3. Quantitative calculations for stress estimation 
  4. Proposal of targeted measures – interventions 
  5. Implementation of Interventions & Review
