"repetitive strain injury"的定义和意义

What is "repetitive strain injury"?

Repetitive strain injury (RSI) is a condition that happens when doing the same movements over and over leads to pain, discomfort, or limited movement in certain body parts. It often affects the hands, wrists, elbows, shoulders, or neck and can be caused by activities like typing, using a computer mouse, playing musical instruments, or working on an assembly line. Symptoms may include pain, stiffness, weakness, numbness, or tingling sensations. Treatment usually involves rest, changing activities to reduce strain, physical therapy, and sometimes medication or surgery for severe cases. Prevention strategies like taking regular breaks, keeping good posture, and using equipment designed for comfort can lower the risk of getting RSI.
