How can ergonomics help in upper limb tasks?

• A. Increase task frequency
• B. Use heavier tools
• C. Minimise frequency of tasks to reduce strain
• D. Extend work hours

Answer: (C)

Ergonomics in upper limb work aims to reduce repetitive strain by shaping tasks to fit how the body moves and recovers. When the same muscles, tendons, and nerves are used repeatedly, small stresses accumulate into fatigue and injury over time. By minimizing how often those tasks are performed, you cut the cumulative load on the joints and soft tissues of the arms, shoulders, and neck. This can be achieved through strategies like designed rest breaks, rotating tasks to spread the workload, and redesigning work to require less repetition, plus using tools and setups that promote neutral positions and lighter forces. In short, lowering the frequency of repetitive actions directly reduces the risk of strain and injury, which is why it’s the best approach. Conversely, increasing repetition, using heavier tools, or extending work hours would raise exposure and harm.
