Repetitive strain injuries (RSIs) refer to a group of musculoskeletal disorders that develop due to overuse, repetitive movements, or prolonged strain on certain muscles, tendons, nerves, or other soft tissues. Also known as repetitive stress injuries or cumulative trauma disorders, RSIs mainly affect the upper body, particularly the hands, wrists, forearms, elbows, shoulders, neck, and back.
These injuries are typically caused by performing repetitive tasks or engaging in activities that involve forceful exertion, long periods of awkward positioning, or constant vibration. Common examples include typing on a keyboard for extended periods, using a computer mouse, working on an assembly line, playing musical instruments, or engaging in sports that involve repetitive motions.
Symptoms of RSIs usually manifest as pain, stiffness, weakness, or numbness in the affected area. The pain may be dull or sharp and may worsen during or after the activity. Other symptoms may include swelling, tingling, or a sensation of burning in the affected region.
If left untreated, RSIs can impair one's ability to perform daily activities and negatively impact overall quality of life. The most effective course of action for RSIs is often resting the affected area, modifying daily activities to reduce strain, applying ice or heat packs, performing stretches or exercises to strengthen and restore flexibility, and using ergonomic equipment or tools. In severe cases, medical intervention including medication, physical therapy, or even surgery may be necessary. Early intervention, ergonomic adjustments, and preventive measures are essential in managing and minimizing the risk of developing RSIs.
