Elderly patients with functionally significant disabilities and handicaps may benefit from a comprehensive rehabilitation program. Patients may be treated while hospitalized or as outpatients. Age itself is not a contraindication to such a program and impaired mentation is not an absolute contraindication. Physiologic changes of aging may adversely affect function, but these effects may be partially reversible (if exacerbated by inactivity)--or may be compensated for by appropriate training. Emphasis is on functionally significant goals that can be achieved within a generally predictable period of time. The achievement of these significant goals would allow the patient to remain in or return to a home setting and avoid institutionalization. Through informed patient assessment and referral, the primary care physician can make optimal use of this resource.
