Designing Knee Braces

Apply the engineering design process to the fields of biology or medicine to solve healthcare problems, and you’re thinking like a biomedical engineer. The storybook Erik’s Unexpected Twist provides a framework for biomedical engineering in this unit with the exciting story of a rescue mission where engineering saves the day for a boy with an injured knee. Students explore the variations in human feet and use the information to make recommendations about sneaker design. They also measure the range of motion in knees as they investigate how a knee joint works. After evaluating the properties of different building materials, they design a knee brace that will restore the range of motion to a model of an injured knee.
