New generation dynamic arm support: lab trials for use

The use of a new generation dynamic arm support prototype is documented under lab trials in pre-clinical technology transfer phase. Control on objects and joysticks by arms is often preferred rather than special interfaces. Mobile arm supports provide UE stability. Mounted on wheelchairs, adjustments are challenges. Mounted on tables they help for feeding, writing, computer access and grooming but setup by attendant is required. Mechanical force is usually provided against gravity to the forearm. Orthotics systems can fit all arm segments and provide support to shoulder and elbow joints dynamically and separately. Thoraco-brachial orthosis usually involve anchoring on trunk braces. Similarly, integration into the seating solution can be done. Techniques inspired by works on UE exoskeletons and orthotics were applied and the arm considered as a “multibody system” with joints mechanics and motions. New ways for low-cost, and optimal designs for 3D print production have been developed.
