Physical medicine and rehabilitation professionals help injured or ill individuals regain lost body functions. Rehabilitation is a crucial part of medicine, because it helps individuals to re-learn body functions, and can help with bowel and bladder problems, problems thinking or reasoning, chewing and swallowing, movement, and speech and language.
Those who are fully trained in physical medicine and rehabilitation have to undergo a residency training program that prepares them to diagnose, treat, prevent, and rehabilitate injuries. The program also teaches students how to conduct physical examinations, create rehabilitation strategies, and assess progress.
Students interested in this field of study must have graduated from medical school, preferably in allopathic or osteopathic medicine. Often, the courses that they'll take to prepare for the residency training are medical ethics, pharmacology, biochemistry, and anatomy.
