Every year, almost all of ½ million infants born prematurely in the US and 15 million worldwide suffer from abnormal brain maturation resulting from interactions between immaturity and atypical sensory experiences after birth. This study uses rigorous scientific methods to measure the effects and determine the mechanisms of action of a parent-supported multisensory neurorehabilitative intervention for preterm infants, adaptable to a wide variety of neonatal environments, even when parents cannot be at their child's bedside. The intervention aims to improve brain multisensory processing, reactions to sensory stimulation in the home and long term language and motor development.

Primary | Index of Multisensory Processing (IMP) | Cortical processing is measured as the percentage of time spent in Event Related Potential (ERP) response patterns that have been previously characterized as typical in healthy infants born at full term. ERP is assessed through high-density functional electroencephalogram (EEG) in the NICU. The Index of Multisensory Processing (IMP) is calculated as the percentage of time that the topographical pattern of the participant's ERP to multisensory stimuli is most like template map of a full term infant. The IMP is expressed as a percentage from 100% (samples show nearly-typical activation all of the time) to 0% (samples show nearly-typical activation none of the time). | At enrollment up to 36 weeks gestation (prior to intervention), and at intervention completion up to 42 weeks gestation | |
Secondary | Infant/Toddler Sensory Profile (ITSP) Score | The Infant/Toddler Sensory Profile (ITSP), for ages 7 to 36 months, is a 48-item questionnaire, completed by caregivers, and is used to measure sensory reactivity and adaptation to the environment. The ITSP assesses five sensory processing sections (Auditory, Visual, Tactile, Vestibular, and Oral Sensory Processing) and a General measure. Responses are given on a 5-point scale where 1 = almost always and 5 = almost never. For children 7 to 36 months there are four quadrant scores and one combined quadrant score available. For children 12 months corrected age, the four quadrant score ranges are as follows:
Low Registration: 11-55 (typical performance is 46-54) Sensation Seeking: 14-70 (typical performance is 19-35) Sensory Sensitivity: 11-55 (typical performance is 41-52) Sensation Avoiding: 12-60 (typical performance is 45-56) Low Threshold (combined quadrant score): 23-115 (typical performance is 87-107) |
at 12 months corrected age | |
Secondary | Change in Bayley Scales of Infant and Toddler Development - 3rd Edition (Bayley III) Score | The Bayley-III is a standardized comprehensive assessment tool for assessing child development in children one month to 42 months old. The highest possible scaled score on each subtest is 19, and the lowest possible score is 1. Scores from 8 to 12 are considered average. Composite scores for motor and language domains are derived from sums of the subtest scaled scores. Composite scores range from 40-160. | 12 and 24 months corrected age | |
Secondary | Change in Preschool Language Scales - 5th Edition (PLS-5) Score | The PLS-5 is a language assessment tool administered by a trained professional in which children point or verbally respond to pictures or objects. It assesses both receptive (auditory comprehension) and expressive language skills in young children, and a total language score is also calculated. Total scores for Auditory Comprehension, Expressive Communication, and Total Language are standardized with a mean of 100 and a standard deviation of 15. Scores below 100 indicate below average performance while scores above 100 indicate better than average performance. | 2 Years (22-26 months corrected age) |
