Beginning in weeks 2-5, patients undergo a 30-minute orientation to the exercise sessions that will be tailored to individual needs and abilities. Patients undergo a 30- to 45-minute group physical activity session twice a week, and a supervised individual session following the same format as the group session, once a week for 4 weeks. After completion of the physical activity intervention, patients complete an activities packet and repeat the physical function and quality of life assessments in weeks 5-6 and again upon readmission for consolidation therapy in weeks 9-13 .
