Battle Balls – The Bone Marrow Transplant (BMT) motto “Out of bed everyday!” The more active a BMT patient is during the transplant process typically the shorter their hospital stay. It can be a struggle for a caregiver to get young patients moving while in the hospital. Battle Balls are small inflatable balls that we provide to pediatric bone marrow transplant or BMT departments in the United States. Battle Balls are the perfect tool to motivate young patients to move. They are small enough to play ball in a hospital room and not damage any equipment.
