Repeated Strain Injury (RSI)
Repeated Strain Injury (RSI), also known as Work-Related Musculoskeletal Disorders (WRMSDs), is a term used to describe the pain felt in muscles, nerves, and tendons caused by repetitive movement and overuse.
Pronunciation
- /rɪˈpiːtɪd streɪn ˈɪndʒəri/
Etymology
The term "Repeated Strain Injury" was first used in the 1980s to describe an increasing number of disorders associated with the use of computers and keyboards. The term "strain" in this context refers to the physical stress that the body endures when performing a repetitive task.
Definition
RSI is a condition that primarily affects people who are involved in tasks that require repetitive motion, such as typing, clicking a mouse, or performing assembly line work. It is characterized by pain, weakness, and numbness in the muscles and joints that are repeatedly used.
Symptoms
Symptoms of RSI can range from mild to severe and may include:
- Pain or tenderness in the affected muscle or joint
- Stiffness and tightness
- Throbbing or pulsating sensation
- Weakness or loss of strength
- Numbness or tingling
Causes
RSI is caused by repetitive movements or prolonged and awkward positions that can damage tissues in the body. These movements can cause inflammation and swelling of the muscles and tendons, leading to pain and discomfort.
Related Terms
Prevention
Prevention strategies for RSI include taking regular breaks from repetitive tasks, using ergonomic equipment, and performing exercises to strengthen the muscles and improve flexibility.
Treatment
Treatment for RSI may include rest, physical therapy, medication, and in some cases, surgery. It is important to seek medical advice if symptoms persist.
