Three parameters of social function-socialization in the home, socialization outside to the home, and hobbies and interests--were analyzed to determine social reintegration of long-term survivors of documented completed stroke, who had already achieved satisfactory levels of physical function as measured by the Kenny self-care evaluation. A significant proportion of survivors manifested social disability, despite complete physical restoration. Much of this disability cannot be accounted for by age, physical impairment or specific neurologic deficits. The distribution of functional disabilities documented suggests that psychosocial factors, as well as organic deficits, are major determinants.
