This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.The purpose of this project is to: define the range of normal activity levels in children stratified by age from 2 to 16 years using the StepWatchTM Monitor, Activity Scale for Kids; and to perform a pilot study of activity and function in two populations of disabled children.The study of typically developing children/youth (TDY) will expand upon an earlier pilot project of normal children and will evaluate the weekly activity of normal boys and girls divided by age into two-year increments. Our goal is to define the normal distribution of children's activity for comparison to future studies of disabled populations and interventions designed to decrease disability as measured by changes in functional activity.
We aim to study 30 boys and 30 girls across seven age brackets for a total of 420 typically developing children. We also aim to do a pilot study in order to evaluate two populations of children with known disability for activity as compared to the normal data set to be collected above. The intent is to look at functional activity in a population of children who have amylopsin and a group of children who have undergone limb salvage surgery for treatment of extremity sarcomas. Both populations are perceived to have daily function significantly below that of age-matched peers. We wish to evaluate 30 children in each population using the StepWatchTM and the self-reported activity, health status and quality of life.
