Physical Activity to Modify Sequelae and Quality of Life in Childhood Acute Lymphoblastic Leukemia

An advanced practice nurse (APN) will meet twice weekly with the patient and family for the first 4 weeks of the intervention to initiate the motivation-based dialogue and therapeutic interaction; this will be followed by once weekly visits during weeks 5-8 of the intervention; and monthly visits during weeks 9-through end of therapy. The physical therapist (PT) will meet at least once weekly with the patient and family during weeks 1-4 to initiate the prescriptive tailored exercise program; subsequent visits to reinforce and modify the program will occur at least once every other week during weeks 5-8, and at least once monthly during weeks 9-135 of the intervention. The PT will visit at least once weekly during weeks 1-4, at least once every other week during weeks 5-8, and at least once monthly during weeks 9-135. During weeks 9-135 of the intervention, the APN will call between the monthly in person-visits, if needed to those randomized to the MAP group to assure fidelity to the intervention and to provide booster support to the intervention where needed.
