Physical means of healing have been practiced since prehistoric times, but Physiatry did not become recognized as a separate medical specialty until 1947. Most widely known as the field of Physical Medicine and Rehabilitation, the medical specialty of modern-day Physiatry comprises the related disciplines of Physical Medicine, Rehabilitation Medicine and Electromyography.

The term Physiatry derives from the Greek words physikos (physical) and iatreia (art of healing). A Physiatrist is a physician who creatively employs physical agents as well as other medical therapeutics to help in the healing and rehabilitation of a patient. Treatment involves the whole person and addresses the physical, emotional and social needs that must be satisfied to successfully restore the patient's quality of life to its maximum potential.

Rehabilitation involves the restoration of a diseased or disabled person to optimal physical, psychological and social functioning.
