The DO training focuses on primary care and emphasizes a whole-person approach to medicine. They also receive extra training in the musculoskeletal system and learn how to providetreatment for muscles and joints using techniques such as stretching, gentle pressure and resistance.

PA, or physician assistant, is licensed to practice medicine with physician supervision. They undergo three years of training. PAs will often perform physical exams, diagnose ailments, request and interpret tests, provide advice on preventive health care, assist in surgery andcan write prescriptions.Though supervised by an MD or DO, physician assistants are able to operate with independence when making decisions.

They can act as a primary care provider to diagnose and care for patients, or they can work in a specialty. Nurse practitioners must have a master’s degree in nursing and a certification to practice as a nurse practitioner.
