IRVINE, Calif., Nov. 7, 2012 /PRNewswire/ -- Freedom Innovations, LLC, a leading developer of high technology prosthetic medical devices, announced today that research participant Zac Vawter utilized the world's first neurally controlled, powered prosthetic limb to climb 103 floors (2,109 steps) of Chicago's Willis Tower at the SkyRise Chicago fundraiser. In this most grueling test of the technology to date, Vawter demonstrated that this advanced research is quickly on its way to becoming available to lower-limb amputees worldwide.
Originally developed at Vanderbilt University, the Powered Knee & Ankle System's neural controls are the result of research from the Rehabilitation Institute of Chicago (RIC). Prosthetic developer Freedom Innovations is on track to commercialize the first phase of the technology, the Powered Knee & Ankle System in early 2015. Further development of the neural-controlled system is underway, as it represents the next step required to fully restore lower-limb amputees' complete biological function.
The computerized prosthetic limb Vawter used in the climb incorporates two significant advancements in prosthetic technology. First, as the only system to feature fully-powered knee and ankle prosthetic joints, the prosthetic limb is no longer passive. Motors in the system replace muscle function lost from an amputation. This facilitates power-driven ambulation that also allows an amputee to actively climb stairs and slopes. Second, Vawter benefited from neural control of this powered system where his thoughts helped to direct the software and action of the prosthetic limb via targeted muscle reinnervation (TMR).
TMR is a surgical procedure pioneered at RIC. Brain signals from nerves severed during amputation are rerouted to intact mu
