Back and neck pain, headaches, and shoulder and arm pain are common computer-related injuries. Such muscle and joint problems can be caused or made worse by poor workstation design, bad posture and sitting for extended periods of time.
Although sitting requires less muscular effort, it still causes fatigue and requires parts of the body to be held steady for long periods of time. This reduces circulation to the muscles, bones, tendons and ligaments and can result in stiffness and pain. If a workstation is not set up properly, these steady positions can put even greater stress on muscles and joints.
