Repetitive Strain Injury
Repetitive Strain Injury (pronounced: rih-PET-ih-tiv STRAYN IN-juh-ree), often abbreviated as RSI, is a general term used to describe the pain felt in muscles, nerves, and tendons caused by repetitive movement and overuse. The condition mostly affects parts of the upper body, such as the forearms and elbows, wrists and hands, and neck and shoulders.
Etymology
The term "Repetitive Strain Injury" was first used in the 1980s to describe an increasing number of disorders associated with the advent of the computer age. The term "strain" in this context refers to the overuse or misuse of a muscle, resulting in injury.
Symptoms
Symptoms of RSI can range from mild to severe and may persist even after the repetitive action has stopped. They include:
- Pain or tenderness in the affected muscle or joint
- Stiffness in the affected area
- Tingling or numbness, especially in the hands or fingers
- Weakness in the hands or forearms. It may be difficult to perform even simple tasks.
- Throbbing or pulsating sensation in the affected area
Causes
RSI is caused by repetitive movements or prolonged awkward positions. The following factors may increase the risk of developing RSI:
- Computer use, especially if the workstation is not set up correctly
- Certain sports, such as tennis or golf
- Playing musical instruments
- Using vibrating equipment
- Heavy lifting or carrying
Prevention and Treatment
Prevention and treatment of RSI often involve ergonomic improvements to a person's workstation, changes in work habits, and physical therapy. Medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), may also be used to relieve pain and reduce inflammation.
