North Carolina State University is seeking a commercial partner to license a novel customized low-dimensional computational musculoskeletal model for prosthesis control.
There are nearly 20,000 upper limb amputations each year. Less than half of all upper-limb amputees wear a prosthetic arm. Unfortunately, upper-limb prosthetics currently on the market are not widely used by amputees because they are not able to duplicate the elegance of the human hand. One limitation, for example, is limited control over the prosthetic. Because prosthetics are not useful tools, patients do not use them.
Researchers at North Carolina State University have developed a novel customized low-dimensional computational musculoskeletal model for prosthesis control. This model allows a user to control more than one prosthesis joint at a time. This robust control allows the user to approximately match a desired hand position. The resulting movement is more natural and human like. In addition, the controller is more robust overall and is more responsive to muscle signal changes associate with arm movement, fatigue, and socket movement.
- Simultaneous control of multiple joints
- Natural human-like movement
- Reduction of system errors
About the Lead Inventor
Dr. Huang received a BS from Xi’an Jiaotong University in China and MS and PhD degrees from Arizona State University. She was a postdoctoral research associate in the Center for Bionic Medicine at the Rehabilitation Institute of Chicago. Prior to joining the NC State faculty, she was an assistant professor from 2008 to 2012 and an associate professor from 2012 to 2013 at the University of Rhode Island, both in biomedical engineering. She has received the Delsys Prize for Innovation in Electromyography, the Mary E. Switzer Fellowship with the National Institute on Disability and Rehabilitation Research and a National Science Foundation CAREER Award. She is a senior member of IEEE and member of the Society for Neuroscience.
