Physical activity and energy expenditure in clinical settings using multisensor activity monitors

Objective methods need to replace subjective methods for accurate quantification of physical activity. To be used in clinical settings objective methods have to show high reliability, validity and feasibility. The commonly used activity monitors are unable to detect the variety of physical activities. Multisensor activity monitors have larger potential for a more accurate quantification of physical activity. Children who have undergone surgery for congenital heart defects have the possibility to a physical active lifestyle because of the progress in cardiac surgery and cardiology.
