To evaluate the feasibility of inpatient rehabilitation during hospitalization followed by a home-based exercise program in older persons who are limited in ambulation when admitted to the hospital. Feasibility will be determined by our ability to identify, recruit and enroll subjects, by the ability of subjects to complete two sessions of rehabilitation each day during the inpatient phase, and by subject adherence to the home-based program. Adherence to the home-based program will be assessed through regular visits and review of activity logs. Criteria for feasibility will be successful recruitment of fifty study subjects meeting inclusion and exclusion criteria, participation in at least 80% of scheduled inpatient rehabilitation sessions and in at least 80% of prescribed home exercise sessions.
