Acute Inpatient Rehabilitation provides intensive, specialized rehab services for patients who have experienced a loss of function from an injury or illness. A proper rehabilitation program can reverse many disabling conditions or can help patients cope with deficits that cannot be reversed by medical care. Rehabilitation addresses the patient's physical, psychological, and environmental needs and is achieved by restoring the patient's physical functions and/or modifying the patient's physical and social environment. The main types of rehabilitation are physical, occupational, and speech therapy. Each rehabilitation program is tailored to the individual patient's needs and can include one or more types of therapy. The patient's physician coordinates the efforts of the rehabilitation team, which can include physical, occupational, speech, or other therapists; nurses; physiatrists (physical medicine and rehabilitation physicians); psychologists; and prosthetists (a therapist who makes artificial limbs or prostheses). Family members are often actively involved in the patient's rehabilitation program.
