SmarToyGym: Smart Detection of Atypical Toy-oriented Actions in At-risk Infants

Recruiting

Phase N/A Results N/A

Trial Description

The study aims to develop a SmarToyGym where sensitized, wireless toys are strategically hung and placed within reach of infants to elicit toy-oriented body and arm/hand movements. Each toy will be equipped with sensors capable of measuring the infant's grasping actions such as squeezing, pinching, tilting, etc.
A low-cost 3D motion capture system will be used to collect video data and the infants' reaching and body kinematics in response to the toys. A pressure mat will be used to measure postural changes to detect weight shifts, rolling, crawling and other movements away from the initial posture. By capitalizing on these wireless and low-cost technologies, it will permit the regular and non-invasive monitoring of infants, which can lead to detailed, non-obtrusive, quantitative evaluation of motor development. In this vein, the investigators also aim to conduct proof-of-concept testing of the SmarToyGym with atypical and typical developing infants. The investigators will include infants' ages 3 to 11 months who are categorized as high-risk or low-risk using the Bayley Infant Neurodevelopmental Screener.

Detailed Description

The proposed research is specifically designed to investigate the ability of a novel tool to identify atypically developing infants from their typically developing peers. Twenty-four infants will be recruited to participate, including 12 who are developing typically and 12 who are identified as at-risk for neuromotor delay. Infants with typical development will be at least 3 months and less than 11 months of age, score in the low-risk category on the Bayley Infant Neurodevelopmental Screener (BINS), score a greater than 85 on all sub-scales of the Bayley Scale of Infant Development (BSID-II), have no history of significant cardiac, orthopedic, or neurological condition, and gestational age at least 37 weeks. Infants at risk for neuromotor delay will be at least 3 months and less than 11 months of age (corrected for preterm birth if applicable), score in the moderate or high risk categories on the BINS, and score an 85 or less on the motor sub-scales of the Bayley Scale of Infant Development (BSID-II). In an effort to decrease variability of the data, infants in each group will be further stratified into an older group (8-10+ months) and a younger group (3-5 months).

Interventions

  • SmarToyGym Device
    Intervention Desc: We aim to develop a SmarToyGym where sensitized, wireless toys are strategically hung and placed within reach of infants to elicit toy-oriented body and arm/hand movements. Each toy will be equipped with sensors capable of measuring the infant's grasping actions such as squeezing, pinching, tilting, etc. A low-cost 3D motion capture system will be used to collect video data and the infants' reaching and body kinematics in response to the toys. A pressure mat will be used to measure postural changes to detect weight shifts, rolling, crawling and other movements away from the initial posture.
    ARM 1: Kind: Experimental
    Label: Infants
    Description: Two populations will be involved in testing in the SmarToyGym: 1. Infants exhibiting typical development between 3 months and 11 months of age 2 . Infants exhibiting atypical development (at-risk for neuromotor delay) between 3 months and 11 months of age.
