Computer Mouse Hand Ache


Why has using the computer mouse become a problem?
Using a mouse as the only input device (as with a computer game) is not hazardous as long as the computer workstation is set up properly and frequent breaks are observed. However, because most people using a mouse in a workplace setting must use the computer keyboard at the same time, using a mouse regularly works the same small muscles over and over again, and can lead to discomfort, pain, and even Workplace Musculoskeletal Disorders (WMSDs).

What makes using a computer mouse hazardous?
There are two reasons why using a mouse regularly can be hazardous.

First, using a mouse requires a person to make small, exact movements with their hand, fingers, and thumb.

By positioning, traveling, scrolling, and clicking the mouse again and again, the same small muscles can become tired and overworked. This can cause:
  1. Pain (ache, soreness) on the top of the hand
  2. Pain (ache, soreness) around the wrist
  3. Pain (ache, soreness) along the forearm and elbow
  4. Formulation of painful nodules, and in the later stages, ganglion cysts, around the joints and along the tendons
  5. Numbness and tingling in the thumb and index finger that may develop into Carpal Tunnel Syndrome (CTS)



What can be done to reduce the risk of injury from using a computer mouse?
Designing a computer workstation which lets a person use a keyboard and a mouse at the same time can be very difficult.

The complete elimination of aches, pains, and WMSD may not be possible, but choosing the right mouse, positioning it properly, and being aware of how you are holding your body and using your muscles can all help.
