New research aims to build lower limb prostheses with human-like reflexes

from O&P News

Researchers at Carnegie Mellon University are developing a lower limb prosthesis based on features of the human reflex, which they hope can increase users' balance and improve current prostheses. "Powered prostheses can help compensate for missing leg muscles, but if amputees are afraid of falling down, they will not use them," Hartmut Geyer, Ph.D., assistant professor of robotics at the university, said in a press release. "Today's prosthe[ses] try to mimic natural leg motion, yet they cannot respond like a healthy human leg would to trips, stumbles and pushes. Our work is motivated by the idea that if we understand how humans control their limbs, we can use those principles to control robotic limbs." more
