Orthotists and prosthetists, also called O&P professionals, design medical supportive devices and measure and fit patients for them. These devices include artificial limbs (arms, hands, legs, and feet), braces, and other medical or surgical devices.
Orthotists and prosthetists typically do the following:
O&P professionals may work in both orthotics and prosthetics, or they may choose to specialize in one. Orthotists are specifically trained to work with medical supportive devices, such as braces and inserts. Prosthetists are specifically trained to work with prostheses, such as artificial limbs and other body parts.
Some O&P professionals may construct devices for their patients. Others supervise the construction of the orthotic or prosthetic devices by medical appliance technicians. For more information, see the profile on medical appliance technicians.
