If the wrist must be bent repeatedly during work, what improvement can be made?
Answer and explanation
Correct answer: Change tool or work height to keep the wrist straight
Adjusting the height of the tool or work surface helps keep the wrist in a neutral, straight position. This reduces repeated strain on the wrist muscles and tendons. Keeping the work farther away may require extra reaching, so it is not an appropriate improvement. Exam tip: In ergonomics questions, prefer adjustments that keep the wrist, neck, and back in neutral postures.
