Rehabilitation is a procedure designed to help patients recover from illnesses, injuries, accidents or physical damage. There are different types of rehabilitation for various disorders, including cardiac, stroke, mental health, physical, kidney, tobacco, stress, alcohol, drug, spinal cord, neurological, vocational, and traumatic brain injury rehabilitations. The rehabilitation process typically involves initial hospitalization, medical treatment, surgery if needed, bed rest, referral to a rehabilitation center, inpatient rehabilitation treatment, and completion of rehabilitation either through outpatient or residential services. The overall goal is to help patients experience positive changes in their abilities.
