Abstract
Abstract This invention relates to a keyboard forearm, wrist and hand support device for use in conjunction with the keyboard of a video display terminal work station. The support device of the present invention is adapted to reduce occurrence of repetitive strain injury by reducing stress on the user's shoulders, arms, wrists and hands. The support device comprises a pair of support members which are interfaced to a frame member via a pair of carriage members. The carriage members are adapted to permit the support members to be movable laterally and longitudinally relative the frame so as to provide complete access to the work surface of a keyboard positioned upon the frame. The support device may further include a finger-activated cursor control interfaced directly to the frame or to a keyboard positioned thereon for selectively positioning a cursor upon a display screen comprising a video display terminal workstation.
