RSI (Repetitive Strain Injury) is a collective term for overuse injuries in the neck, shoulders, arms, and hands, often resulting from prolonged, repetitive computer work in static postures. The condition can include tennis elbow, muscle pain, tenosynovitis, or nerve entrapment.
What is RSI?
RSI is not a single injury but a collective term for load-related complaints in the neck, shoulder, arm, wrist, or hand, often resulting from static and repetitive computer work. It often manifests as aching or stiffness in the neck, shoulder, arm, wrist, or hand. RSI can encompass several diagnoses, including tennis elbow.
Common Causes & Risk Factors
RSI almost always arises due to repetitive movements, often in static work postures related to computer work. Prolonged work with a bent wrist over the computer mouse, combined with small repeated movements, leads to overload. A poorly adjusted work environment with incorrect desk or chair height further increases the risk, as does psychological stress. People who use the computer mouse for many hours daily, are particularly exposed.
Symptoms
- Pain and perceived weakness in the affected area, worsening with computer work
- Tenderness on pressure over the overloaded area
- Stiffness in the neck, shoulder, elbow, or wrist
- For chronic conditions, also pain at rest
When should you seek medical attention?
If the pain does not improve within a few weeks after self-care with ergonomic adjustments and supportive aids, you should contact a healthcare provider or physiotherapist for further investigation.
Recommended Supports & Braces
For RSI, an important measure is to try to switch to a more ergonomic working posture. Moving the elbows closer to the body can reduce the strain on the shoulders. Micro-breaks during work and varying work postures can also reduce discomfort. Ergonomic aids, such as a vertical mouse or an adjustable workstation, are often an important part of the treatment. A wrist support can help relieve the forearm. Stretching and targeted rehabilitation training can further improve the healing process.
