The placement
and usage of your PC mouse can significantly influence your wrist health and
overall comfort during work or gaming. Prolonged use without proper positioning
can lead to discomfort, repetitive strain injuries (RSIs), and even chronic
conditions like carpal tunnel syndrome. By understanding the science behind
mouse ergonomics and adopting the correct placement strategies, you can protect
your wrists and improve productivity.
The Science
of Wrist Strain and Mouse Usage
Using a mouse repeatedly over long periods exerts pressure on the tendons, ligaments, and the median nerve inside the wrist. These structures pass through the narrow carpal tunnel, and improper mouse placement can compress this area, leading to carpal tunnel syndrome (CTS). A study published in the Journal of Orthopaedic Research confirmed that excessive wrist extension or flexion increases tension in the tendons, causing inflammation and discomfort (source).
