Some conditions involve several body systems and can lead to significant disability. These conditions—such as stroke, spinal cord injury, and major cardiopulmonary (heart and lung) problems—are usually addressed by a team of health professionals through programs such as cardiac rehab and stroke rehab. The team can include doctors; nurses; physical, occupational, and speech therapists; psychologists; and social workers, among others.

Physical therapists are a critical part of this team. They address the issues of range of motion, strength, endurance, mobility (walking, going up and down stairs, getting in and out of a bed or chair), and safety. The physical therapist may also get you the equipment you need, such as a walker or wheelchair, and make sure you can use the equipment appropriately.
