Three University of Iowa engineering students were searching for a bioscience project, and one horsewoman, Mona Metcalf, had a life-impacting problem for them. The Daily Iowan reports on students Paighton Schrupp, Madison Chrisman, Glen Schoenbeck Jr. and Elizabeth Niedert worked with Metcalf to design a specialty attachment for Metcalf’s prosthetic leg so she could start riding her horse, Rebel, again. The team invited Metcalf and her daughter to the final presentation on Friday, and Metcalf will then bring the attachment home for some well-deserved trail time with Rebel.
