Abstract: A dynamic wrist rest for use with a computer keyboard for the prevention of carpel tunnel syndrome is provided. The wrist rest provides for a constant up and down motion of the wrist through an internally mounted pressure sensitive air bladder. The up and down motion can also be provided by a motor and gear driven belt and pulley system that provides a lower speed and high torque which functions to rotate a roller along the interior surface of the support surface of the wrist rest thus creating the up and down motion. The up and down motion can also be provided by a motor driven, internally mounted oblong roller that is mounted for rotation about its axis.
