Jenn Cao, a graduate student in the College of Engineering, has created a prototype of a type of brace to help people with arthritic knees walk easier.
A version of the device, called an exoskeleton, is used in the military and is extremely expensive.
Cao has created a new prototype in a UNT lab that could help increase the knee's range of motion. It could also help with knee weakness, pain, and knees that have trouble bending.
The prototype is part of her thesis.
