Automated assessment of infant motor development to predict infant age: The determination of objective metrics of spontaneous kicking
Katelyn Fry-Hilderbrand, Yu-Ping Chen, Ayanna Howard
TL;DR
This study uses wearable sensors to track infant kicking patterns and predict age, helping detect motor delays early.
Contribution
A novel method for assessing infant motor development using spontaneous kicking data from a wearable sensing suit.
Findings
Kinematic features like frequency and duration of kicks correlate significantly with infant age.
Preterm infants show different developmental kicking trends compared to term infants.
Normative kicking metrics were established using data from typically developing term infants.
Abstract
Though early intervention can improve outcomes for children with motor disabilities, delays in diagnosis can impact the success of intervention programs. Prior work indicates that spontaneous kicking patterns can be used to model typical infant motor development to assist in the early detection of motor delays. However, abnormalities in spontaneous movements are not well defined or readily observable through traditional functional assessments. In this research, a method is introduced for the early detection of delays through the assessment of spontaneous kicking data gathered using a wearable sensing suit. We present formulations of kinematic features identified in the clinical space, identify which features are significant predictors of infant age, and establish normative values. Finally, we offer an analysis of preterm (PT) infant data compared to normative values derived from term…
