Ever noticed someone wearing an artificial limb or brace to help them get around more easily? You've probably never stopped to think about where these things come from, but those are things an orthotist or prosthetist handles. O&P professionals, as they're often called, work directly with doctors to fit patients with medical support devices. They perform exams, take measurements and make molds, tell suppliers how items should be made, and fit the finished devices to patients. Because many people who seek out the care of an O&P have lost limbs through tragic circumstances (such as combat or accidents), it's important that you see yourself as a compassionate person if you plan to do this kind of work. What makes this job especially rewarding is giving people the chance to regain abilities they thought were lost—like carrying and lifting things, walking, running, and even dancing.
