For Medical Personnel

We are working to identify clinical transition partners to leverage and advance Revolutionizing Prosthetics technologies. The Modular Prosthetic Limb (MPL) can accommodate all amputation levels, from wrist to shoulder disarticulation. It can also be used as an assistive device for spinal cord injury patients.

The Revolutionizing Prosthetics program continues to develop neural decode algorithms that translate electrical signals received from the body into commands for the limb systems or other devices. The MPL control and sensory feedback systems are designed to accommodate interfaces with varying degrees of invasiveness:

Non-invasive devices

Minimally invasive devices

Moderately invasive devices

Highly invasive devices

Non-invasive control of the prototype limbs has been demonstrated repeatedly, and in September 2011, the MPL was controlled by a volunteer with tetraplegia via ECoG—the first-ever accomplishment of prosthetic arm control with this modality by an individual with a disability. This effort, conducted at the University of Pittsburgh Medical Center (UPMC), will be followed by preclinical trials at UPMC and the California Institute of Technology seeking to achieve brain control by using advanced electrode arrays in five volunteers with spinal cord injuries.
