Best Ergonomic Computer Mouse for Lateral Epicondylitis (Tennis Elbow)
By Stephen Bowden, Chartered Ergonomist
When it comes to choosing an ergonomic mouse, the options can be overwhelming. If you’re seeking the best ergonomic mouse to help manage lateral epicondylitis—commonly known as Tennis Elbow—this post offers essential background on the condition and practical tips to reduce discomfort.
Understanding Lateral Epicondylitis
Lateral epicondylitis is a condition characterized by pain on the outer side of the elbow. Despite its nickname, “Tennis Elbow,” the condition most often affects non-tennis players. In fact, although computer mouse use may aggravate the symptoms, scientific evidence linking it directly to lateral epicondylitis is limited.[]
Who Is Affected?
- Dominant Arm Involvement: The condition typically affects the dominant arm.
- Middle-Aged and Female Patients: It appears more commonly in middle-aged individuals and women, though it can affect anyone.
- Bilateral Occurrence: In some cases, both arms may be involved simultaneously.
Common Triggers
Lateral epicondylitis is usually provoked by repeated and forceful wrist extension or twisting of the forearm. Activities outside of work—such as sports, hobbies, or even everyday actions like holding a cup—can contribute to the development or exacerbation of the condition. Although direct trauma (such as a blow to the elbow) is rare, it remains a possible cause.
Recognizing the Symptoms
The onset of lateral epicondylitis is often gradual, starting with a mild, intermittent ache around the outer elbow or forearm. As the condition progresses, you may experience:
- Localized Pain: Initially focused at the outside of the elbow, but it may extend down the forearm to the back of the hand and into the middle and ring fingers.
- Increased Pain with Movement: Actions such as gripping, shaking hands, or even holding a cup can become particularly painful.
- Sleep Disturbances: In severe cases, the pain can interrupt sleep.
- Distinguishing from Neck Issues: Although nerve irritation in the neck can produce similar symptoms, it is typically accompanied by pins and needles, numbness, or muscle weakness.
Ergonomic Strategies to Manage Discomfort
For those who use a computer regularly, several simple adjustments can help reduce aggravating factors associated with keyboard and mouse use:
1. Optimize Keyboard Setup
Avoid using keyboard supports that tilt the keyboard. When the keyboard is angled, you may need to extend your wrist to type, which can worsen lateral epicondylitis. Keeping your keyboard flat—such as with the new Kinesis Ergonomic Keyboard—helps maintain a more neutral wrist position.
2. Choose the Right Mouse
A vertical mouse allows your hand to assume a more natural, near-vertical “position of function/rest” rather than a flat, pronated posture. This neutral position minimizes wrist extension and forearm twisting—both known aggregators of Tennis Elbow. However, be cautious: some vertical mouse designs mistakenly claim that the “hand shake” grip is neutral, when true neutrality is achieved only when the hand is held lightly at the fingertips with a slight gap between the mouse and the palm. The DXT Ergonomic Mouse (Watch video below) exemplifies this ideal by allowing effortless switching between the right and left hand, distributing repetitive strain more evenly.
3. Incorporate Targeted Exercises
Simple exercises can help relieve tension and build strength in the affected muscles. Regular stretching and strengthening routines—many of which are detailed on the CSP website—can be a valuable addition to your RSI management strategy.

By integrating these ergonomic strategies into your daily routine—optimizing keyboard setup, selecting the right mouse, and exercising regularly—you can help manage or even prevent the discomfort associated with lateral epicondylitis. Choose wisely and be proactive to ensure your digital workspace supports your health.
