An orthotist works with orthotics, prosthetics, and other medical support devices to ensure they fit patients and function properly. Orthotists are often responsible for developing a treatment program for patients, while an actual technician creates the devices. As an orthotist, your duties include making measurements, selecting and adjusting devices, teaching patients how to use the devices, and checking on patient progress. The career requires an intimate knowledge of all orthotics and prosthetics, including artificial limbs, physical braces, and corrective shoes.
