Abstract: Background: Approximately 500,000 persons in the United States suffer a stroke each year; the majority of these individuals are 6S years of age or older. The neurological impairment occurring as the result of stroke can lead to both acute and chronic disability. Further medical complication and disability are often the result of immobility-related Uloess that occurs whne the patient is still in the hospital. Methods: A MEDLINE search for articles published from 1980 to 1990 was made using the key words immobilization and stroke rehabilitation. The bibliographies of these articles, key rehabilitation and geriatric textbooks, the bibliographies of these textbooks, and the authors' personal files were also sources of information. Results tmtl Conclusions: Immobility-related medical complication and disability can be substantially reduced by identifying risk factors and applying preventive measures. As long-term providers of medical care, family physicians are in a position to devise a preventive care pJan for immobility-related disability and to appreciate the beneficial effects of such a plan on patient outcome. 0 Am Board Fam Pract 1992; 5:389-97.)
