Wireless Non-Invasive Advanced Control of Microprocessor Prostheses and Orthoses

There are several current and imminent orthotic and prosthetic (O&P) fitting scenarios that would greatly benefit from the ability to wirelessly collect and transmit physiological information from the user. Both upper- and lower- limb O&P fittings that: 1) use osseointegration, 2) have cable management issues, and 3) could benefit from physiological information from locations proximal to the prosthetic socket/orthosis, would all be strong candidates to utilize wireless physiological sensors. Therefore, Liberating Technologies Inc. (LTI), along with its partners at Worcester Polytechnic Institute, aim to create the Asterisk system: a wireless toolkit to allow the interface of current and future physiological sensors with orthotic and prosthetic systems. In Phase 2 we will implement technical advancements to our Phase 1 design, develop a mobile application to allow for system configuration, perform laboratory and take-home testing with human subjects to verify the system's ability to improve functional performance and identify areas for future improvement.
