"I just want to get better": experiences of children and youth with juvenile idiopathic arthritis in a home-based exercise intervention.

Major barriers to and facilitators to exercise for children with JIA fell into three categories: personal, social and programmatic factors. These barriers were not unlike those that emerged in previous exercise intervention trials with healthy children and youth. There is a need to develop effective strategies to engage children in physical activity and to overcome barriers that prevent them from doing so. Future initiatives may potentially engage children in developing solutions to enhance their participation in and commitment to physical activity.
