Ewwww! I don’t like that metaphor either. But gore aside, workers often find the “best way” to do a task. And ergonomists are sometimes asked to evaluate alternative methods. How do we do this? We use objective analysis tools to compare methods. Some ergonomists use motion capture tools, which evaluate how much time is spent […]

This week, I wanted to explore the impact of frequency and duration. “How often” and “for how long” an effort occurs have a big effect […]

We can use a force gauge to measure the weights and push/pull forces required on the job. You might also think […]
