The ArmeoSpring is based on an ergonomic arm exoskeleton with integrated springs. It embraces the whole arm, from shoulder to the hand, and counterbalances an adjustable part of the weight of the patients’ arm, enhancing any residual function and neuromuscular control, and assisting active movement across a large 3D workspace. The pressure sensitive handgrip is not only an input device for exercises, but also a computer interface for the software and computer games, and can be removed for functional training of real life tasks. The Augmented Performance Feedback for ArmeoSpring contains a extensive library of game-like movement exercises supported by a virtual-reality training environment.
