Family and general practitioners are often called primary care physicians. They diagnose, treat and help prevent disease and injuries. Family practitioners may refer patients to doctors who are experts in certain diseases, called specialists, when further treatment is needed.

Physical therapists assess patients and create plans to help them improve their movement, relieve pain and increase strength. They evaluate the effects of treatment and adjust to maximize the benefits. Physical therapists also test the patient’s strength, motor skills and functions, sensory perceptions, respiratory or circulatory efficiency and show patients how to perform the prescribed exercises and review progress. Physical therapists help decrease or prevent problems due to disease or injury.

Physician assistants provide health care services under a physician’s supervision. They perform tasks that are usually performed by doctors. They conduct physical exams and provide treatment, and counsel patients. Physician assistants may prescribe medications.
