ANGOLA â Prosthetics can be a blessing for people who are missing a limb, but theyâre also very expensive. That expense can make them impractical for children and adolescents who are constantly growing and changing. However, a senior design group of Trine University engineering majors completed a project this year that provided solutions for two teenage girls born without left hands. With support from the Kosciusko County Community Foundationâs Helping Hands Fund, the team of Marissa Shaver, a biomedical engineering major from Fostoria, Ohio, Ben Avey, a mechanical engineering major from Pendleton, David Cervera, a biomedical engineering major from South Bend and Karina Bruce, a biomedical engineering major from Findlay, Ohio, designed low-cost prosthetics that will allow the girls to perform routine tasks such as curling their hair.
