Epilepsy is common in childhood. Throughout life, including adulthood, children with epilepsy are at increased risk of impaired health, functioning, psychological well-being and quality-of-life. There is evidence that physical activity improves the medical and psychosocial aspects of health in adults with epilepsy- but there are no such studies in children. The investigators predict that we can increase levels of physical activity and influence children's functioning, psychological well-being and quality of life through multiple pathways. The investigators propose to evaluate the relationship between enhanced physical activity and health, and explore facilitators and barriers to physical activity in children with epilepsy.
