Use of a Wearable Accelerometer to Detect Pediatric Motor Activity Deficits: Upper Limb Activity of Typically Developing Children

Developmental delays in children are common but can be difficult to detect by parents and pediatricians. Researchers looked at the ability of a wearable accelerometer to distinguish children with from those without upper extremity motor deficits suggestive of developmental delay. This video animates histograms that represent the activity distribution of unilateral movements of each upper limb for each visit in a typically developing reference child cohort, presented from youngest to oldest.
