Ergonomics includes all of the following EXCEPT which?

• A. Reducing repetitive movements through technique
• B. Proper workstation setup
• C. Safe lifting techniques
• D. Determining which repetitive movements will be most effective

Answer: (D)

Ergonomics is about designing tasks and workplaces to fit the worker, reducing risk, and improving comfort and efficiency. Teaching proper technique to reduce repetitive movements helps prevent repetitive strain injuries, so it fits. Setting up the workstation correctly keeps the body in a neutral, safe posture, which is another ergonomic goal. Learning safe lifting techniques protects the back and prevents acute injuries, also part of ergonomics. The idea of determining which repetitive movements will be most effective focuses on choosing movements for productivity or performance, not on reducing risk or fitting the job to the person. That makes it outside the typical scope of ergonomics, which is why it’s the exception.
