Now that we have looked at the extent of the problem let’s consider the causes.

Mouse use is a risk factor for neck and wrist discomfort.

Activities that involve force, repetitive movements and awkward postures particularly when the joint is near the end of its range of movement can cause damage to muscles and joints. A lack of rest breaks prevents recovery and adds to the problem. Other causes include lifting and handling, direct pressure on body tissues, vibration and cold work environments.

Research has shown that poorly set up workstations and the static activity of working on computers is linked to more musculoskeletal discomfort. Poor posture, incorrectly set up workstations and bad work habits contribute to RSI. Mouse use, particularly the arm posture involved, is a risk factor for musculoskeletal symptoms including neck and wrist discomfort.
