Risks of Using Trackball Mice

Trackball mice, distinct from traditional mice, utilize a stationary ball to navigate the cursor. While they offer some ergonomic advantages, improper usage can also lead to specific health-related concerns. Understanding these risks is crucial for ensuring comfort and preventing potential long-term damage.

1. Repetitive Strain Injuries (RSIs)

Overuse or improper positioning of the hand while using a trackball mouse can lead to repetitive motions, straining the muscles and tendons. Common RSIs linked to this include:

  • Carpal Tunnel Syndrome: Resulting from pressure on the median nerve, causing numbness and tingling in the hand.
  • Thumb Tendinitis: Inflammation or irritation of the thumb tendons due to over-reliance on the thumb to operate the trackball.

2. Postural Issues

If the trackball mouse isn't positioned properly, users might unconsciously lean, reach, or twist their wrists to operate it. This misalignment can lead to:

  • Neck and shoulder discomfort
  • Upper and lower back issues
  • Wrist pain due to twisting or hyperextension

3. Increased Muscle Fatigue

Since a trackball mouse remains stationary, users might exert more force than necessary, leading to rapid muscle fatigue. Over time, this can cause muscle strains, particularly if one doesn't take regular breaks.

4. Decreased Efficiency and Productivity

Improper ergonomics can also hamper work performance. Discomfort can lead to frequent breaks, reduced concentration, and a decrease in overall productivity.


While trackball mice can be a suitable ergonomic choice for many, it's vital to use them correctly to prevent potential health issues. Regular breaks, proper positioning, and being mindful of the force exerted can make a world of difference. For those who spend a significant amount of time on computers, it's worth considering tools like BLiiNK.
