Clinimetric Review of Motion Sensors in Children and Adolescents

  • Published on November 2006

Background and Objectives To review the clinimetric quality of motion sensors used to assess physical activity in healthy children and adolescents (2-18 years). Methods A systematic literature search was performed in PubMed, Embase, and SpycINFO. The clinimetric quality of two pedometers (Digi-Walker3 Pedoboy), four one-dimensional accelerometers (LSI, Caltrac, Actiwatch, CSA/...


Physical activity in the United States measured by accelerometer

  • Added on June 1, 2008

PURPOSE To describe physical activity levels of children (6-11 yr), adolescents (12-19 yr), and adults (20+ yr), using objective data obtained with accelerometers from a representative sample of the U.S. population. METHODS These results were obtained from the 2003-2004 National Health and Nutritional Examination Survey (NHANES), a cross-sectional study of ...


Calibration of accelerometer output for children

  • Added on November 1, 2005

Understanding the determinants of physical activity behavior in children and youths is essential to the design and implementation of intervention studies to increase physical activity. Objective methods to assess physical activity behavior using various types of motion detectors have been recommended as an alternative to self-report for this population because ...
