There are many unfounded assumptions about the dangers of exercise in children with epilepsy - assumptions that may be seriously detrimental to children's health, and that we have good reason to challenge. This project explores the innovative idea that enhancing physical activity in children with epilepsy will have a positive effect on medical and psychosocial outcomes. The primary purpose of this study is to examine whether increasing physical activity levels through a six-month walking program, that includes behavioral counselling and self-monitoring of physical activity, as compared to varied un-standardized current practices, positively influences health and quality of life over one year. The secondary purposes are to (i) determine which environmental and personal facilitators and barriers to physical activity are experienced when increasing physical activity levels through a six-month walking program; (ii) determine if physical activity levels established during the six-month program will be sustained over a subsequent six-month period that includes self-monitoring of physical activity only; (iii) identify aspects of health that are amendable to change with enhanced physical activity, and explore the relationships among physical activity and impairments, functioning, psychological well-being and quality of life; and (iv) assess if there is a dose-response relationship between physical activity and a variety of health and social factors and quality of life.
