Mouse Arm – Causes, Symptoms and Ergonomic Solutions
Mouse elbow, or lateral epicondylitis, is a painful condition that affects the tendon attachment on the outside of the elbow. The problems usually occur after prolonged work at a computer with a mouse, where the hand and wrist are stressed on one side. Mouse elbow and tennis elbow are the same injury, but with different triggers – mouse elbow is particularly common in office environments.
What is mouse arm?
Mouse elbow is an inflammation of the tendon attachment on the outside of the elbow, where the extensor muscles of the forearm attach. The pain often radiates from the elbow into the forearm and worsens with strain. Although the problem is located in the elbow, repetitive movements of the hand and wrist are the most common cause.
Common causes & risk factors
Mouse arm almost always occurs due to one-sided movements in connection with computer work. Prolonged work with a bent wrist over the computer mouse, combined with small repeated movements, leads to overload. A poorly adapted work environment with the wrong height of the desk or chair increases the risk even more. People between the ages of 30 and 50, and especially those who use the computer mouse for many hours daily, are particularly at risk.
Symptoms
- Dull or sharp pain on the outside of the elbow
- Tenderness when pressed over the inflamed tendon attachment
- Some stiffness in the elbow joint
- Perceived weakness in the hand and wrist
- Pain that worsens when working with a computer mouse
When should you seek medical attention?
If the pain does not improve after self-care with ergonomic adjustments and relieving protection measures within a few weeks, you should contact a healthcare provider or physiotherapist for further investigation.
Recommended protection & support
Relief is a central part of rehabilitation. A mouse arm brace, placed just below the elbow, reduces the strain on the tendon attachment and relieves pain. Wrist supports can also help relieve the pressure on the forearm and reduce the risk of incorrect strain when working on a computer. Ergonomic aids, such as a vertical mouse or adjustable workstation, are often an important part of treatment. Stretching and exercises for the forearm can further enhance the healing process.
