Study summary

The Sickle Cell Children's Exercise Study (SuCCESs) will explore the feasibility and effects of a moderate intensity strengthening, balance, speed, and agility intervention program in children with sickle cell disease.

Read the detailed description

Participants will perform the baseline assessment and after six weeks of performing the SuCCESs program the participants will perform a post-intervention assessment. Participants will be asked to attend a total of six physical therapy in-person sessions (1x/week) at the University of Maryland Department of Physical Therapy and Rehabilitation Science and to perform 12 home program sessions.
