Apparatus and method for reducing repetitive or maintained stress injuries

摘要

An arm rest assembly is usable with a mouse pad or keyboard and provides vertical support for a user's arm to avoid fatigue and injury. The assembly has at least one forearm cradle and a thin profile which allows a mouse or digitizer pad to be placed on an assembly platen or to insert the assembly under a keyboard and support both forearms of the using while striking the keys of the keyboard with both hands. The assembly further includes a detachable slide which is pivotable and, at the same time, allows linear movement of the arm toward and away from the assembly. An interchangeable cradle for the user's forearm has springs to counteract the arm weight and to make the cradle stable in the horizontal position while permitting some tilting.
