The purpose of the study was to examine the accuracy of pedometer steps and activity time (Walk4Life, WL) for youth with developmental disabilities. Eighteen youth (11 girls, 7 boys) 4-14 years completed six 80-meter self-paced walking trials while wearing a pedometer at five waist locations (front right, front left, back right, back left, middle back). Trials were video taped to determine actual steps and activity time. Time exhibited a smaller percent error in comparison to steps across locations. Apart from the front left, location had minimal influence on accuracy. The WL demonstrates acceptable accuracy for steps and activity time.
