Distribution of the main ergonomic factors and ergonomic scores in the factory

Ergonomic factors
Types of work situations (number of workers)High repetitiveness N (%)Force >1 kg N (%)Elbow above mid torso N (%)Forearm twisting N (%)Wrist flexion >45° N (%)Wrist extension >45° N (%)Wrist deviation N (%)Rapid triggering motions N (%)Mechanical stress ≥1 N (%)Bilateral ergonomic score ≥8 N (%)
Total number of work situations examined = 238.
