Neural control technologies show promise in joint NCSU-UNC prosthetics project


This image shows the study participant performing a squatting activity with different prosthetic devices. When the participant used his daily prosthesis (left picture) he had a limited range of motion and had to bend his back significantly to lift objects off the ground. When using a neural controlled prosthetic ankle (right picture) he was able to voluntarily control his prosthesis ankle joint force and angle and keep a healthy posture while lifting weight from the ground.

RALEIGH – A recent case study from North Carolina State University and the University of North Carolina at Chapel Hill demonstrates that, with training, neural control of a powered prosthetic ankle can restore a wide range of abilities, including standing on very challenging surfaces and squatting. The researchers are currently working with a larger group of study participants to see how broadly applicable the findings may be. ....

Study Shows Powered Prosthetic Ankles Can Restore a Wide Range of Functions for Amputees
A recent case study from North Carolina State University and the University of North Carolina at Chapel Hill demonstrates that, with training, neural control of a powered prosthetic ankle can restore a wide range of abilities, including standing on very challenging surfaces and squatting. The researchers are currently working with a larger group of study participants to see how broadly applicable the findings may be.
“This case study shows that it is possible to use these neural control technologies, in which devices respond to electrical signals from a patient’s muscles, to help patients using robotic prosthetic ankles move more naturally and intuitively,” says Helen Huang, corresponding author of the study. Huang is the Jackson Family Distinguished Professor in the Joint Department of Biomedical Engineering at NC State and UNC. ....

Textile Sensor Patch Could Detect Pressure Points for Amputees


 
In IEEE Sensors Journal, researchers from North Carolina State University reported on the lightweight, soft textile-based sensor prototype patch. The device incorporates a lattice of conductive yarns and is connected to a tiny computer. They tested the system on a prosthetic limb and in walking experiments with two human volunteers, finding the system could reliably track pressure changes in real time. For further information see the IDTechEx report on Wearable Sensors 2021-2031.
 
What people commonly use to measure pressure within prosthetics are rigid sensors, said the study s first author Jordan Tabor, a graduate student in the NC State College of Textiles. ....
