GradImpact: Improving Mobility for Children with Cerebral Palsy

    As the most common physical disability in childhood, one in 323 babies is diagnosed with Cerebral Palsy (CP) annually in the U.S. and most require medical devices to improve mobility. CP is a life-long disability due to damage of the developing brain, and there is no known cure. Ahad Behboodi, a doctoral candidate in biomechanics and movement science at the University of Delaware, is leading a team of researchers to improve mobility in children with CP.


    Behboodi and his team recently received a QED grant from the University City Science Center in Philadelphia, “to develop a motorized ankle foot device for children with Cerebral Palsy that includes a novel artificial muscle.” The device will help correct and improve ankle motion, potentially leading to better mobility. Comprised of common elastic materials, the artificial muscle device is lightweight and compact and simulates the motion of skeletal muscle.


    “For now, the device can only assist the wearer’s own muscle contractions, but we are able to customize where we put the force to change the movement,” said Behboodi. “In the future, we may add functional electrical stimulation technology, which is a major area of research in Dr. Lee’s lab, to also trigger muscles, when needed. This would improve the timing and power of the muscle’s activation, thereby strengthening the muscle and improving the user’s walking coordination.” To learn more about Ahad’s work, visit the University of Delaware website.

    The CGS GRADIMPACT project draws from member examples to tell the larger story of graduate education. Our goal is to demonstrate the importance of graduate education not only to degree holders, but also to the communities where we live and work. Do you have a great story to share about the impact of master’s or doctoral education? Visit our WEBSITE for more information.


    CGS is the leading source of information, data analysis, and trends in graduate education. Our benchmarking data help member institutions to assess performance in key areas, make informed decisions, and develop plans that are suited to their goals.
    CGS Best Practice initiatives address common challenges in graduate education by supporting institutional innovations and sharing effective practices with the graduate community. Our programs have provided millions of dollars of support for improvement and innovation projects at member institutions.
    As the national voice for graduate education, CGS serves as a resource on issues regarding graduate education, research, and scholarship. CGS collaborates with other national stakeholders to advance the graduate education community in the policy and advocacy arenas.  
    CGS is an authority on global trends in graduate education and a leader in the international graduate community. Our resources and meetings on global issues help members internationalize their campuses, develop sustainable collaborations, and prepare their students for a global future.
