The Foot Orthosis Project Presented by: Juliet DeMeo and Cristiana Stan

Introduction The Foot Orthosis was an intricate yet enjoyable experience for us future engineers. Our dilemma was a patient with Cerebral Palsy is unable to walk in a normal upright position, they have stiff muscles in one of their legs, creating the problem of them walking on the ball of their foot. In result, the patient's foot is getting damaged. The Foot Orthosis must keep that from happening, allowing the patient to dorsiflex (the upward pointing of the foot) and not plantarflex (downward movement of the foot). It also must allow it to stay in a normal position.

The Beginning of Our Process We had to create the solution with this limited amount of supplies: Bubble Wrap -18 inches Wood - Up to 6 pieces. Each piece was 8”x3/4 ”x1/8” thick Cotton line- 2’ Velcro - 1’ 3 pieces of Felt 3 pieces of card stock 2 paper fasteners 2’ of wire 4 rubber bands 2’ of duct tape Our first step was to assign jobs to each person in each group, we all ended up building together, but we had other specific jobs for each person. The jobs were The presenter (Angeleena Prince), The tester (Cristiana Stan), The product manager (Tess Korten), and the recorder (Juliet DeMeo). Next step was to sketch up ideas for the Foot Orthosis. In the end we combined a few aspects of each sketch into our final idea.

Building Time! After we got the a “a-okay” from Mr.Ponterio, we began to build. The orthosis had to fit the tester, so we built around her foot and lower leg. Our idea was to use bubble wrap for the main building material. Using almost all the materials, we created a solution. Even if it didn’t work, it taught us how to think through a problem and find a solution.
