Prosthetics

UPMC/Pitt Health Sciences

Prosthetics researchers at the University of Pittsburgh have landed a $5.3 million grant from the National Institutes of Health to develop a lower limb prosthesis that mimics the feeling of a leg or foot.

Current prosthetics lack sensory feedback, so people who have lost a leg often struggle to walk. To recreate the sensations of balance and pressure, researchers are experimenting with an implant that transmits electronic signals to a simulator worn on the belt.

Advances in 3-D printing are making prosthetic limbs more affordable and easier to acquire.

A global community called e-Nabling the Future is making low-cost prosthetic hands across the world. A traditional prosthetic limb can cost a person thousands of dollars, but the hands produced by e-Nabling, are free.

It’s a common plot point in science fiction stories – someone loses an arm and gets a prosthetic limb that can move and feel just like the original. And, that’s exactly what researchers at the University of Pittsburgh are working toward.

Clinicians, engineers and scientists have teamed up to develop prosthetic arms that not only move naturally, but also allow the wearer to experience the sensation of touch.
