Biomedical engineers play a very important role in medicine. They design technologies that help solve problems with the human body, which can include x-rays, artificial limbs, casts, braces, and even surgical instruments. They work closely with doctors and nurses to improve upon technologies that already help solve problems related to medicine and the human body.
In order to design a knee brace for an injured knee, it is important to know how a healthy knee moves. Using a goniometer, fourth graders are taking measurements of their own knees to see just how they move. Extending their legs in four different directions, the readings on the goniometer will influence their own knee brace designs.
