A Study to Evaluate Web-Based Physical Activity Intervention in Children and Adolescents with Newly Diagnosed Acute Lymphoblastic Leukemia in First Remission


About this study

The primary purpose of this study is to compare the effects of a rewards-and web-based physical activity intervention that includes structured social interaction between participants to the same web-based physical activity intervention that does not include structured social interaction on fitness among children and adolescents following treatment for cancer.
