 +Comfort Guidelines - Important Ergonomic Information
Whether you spend five minutes or five hours using your keyboard, mouse or trackball, these
suggestions can help you stay comfortable and productive. Some research suggests that
long periods of repetitive motion,
using an improperly set up work space,
incorrect body position, and
poor work habits
may be associated with physical discomfort and injury to nerves, tendons, and muscles. If you
feel pain, numbness, tingling, weakness, swelling, burning, cramping, or stiffness in your hands,
wrists, arms, shoulder, neck, or back, see a qualified health professional.
Follow the guidelines in the guidelines PDF file below to maximize your comfort and lessen the
chance of injury.
