What does RSI mean and what causes it?

RSI stands for Repetitive Strain Injury, a condition resulting from repetitive movements or overuse of muscles, tendons, and nerves, often affecting areas like the wrists, hands, and arms. It commonly arises from activities such as typing, using a mouse, or performing repetitive manual tasks. Factors contributing to RSI include poor ergonomics, inadequate breaks, and improper technique. Symptoms may include pain, stiffness, and reduced mobility in the affected areas.
