Clinical Trial Summary

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.

Description:

This study is a randomized controlled trial design with intent-to-treat analysis in hospitalized preterm infants between 32 and 36 weeks post-menstrual age. Both the control and intervention groups will receive routine neonatal intensive care unit care (i.e., skin-to-skin care by parent when available and daily sessions of exposure to recorded parent's voice). In addition to routine care, the parent-supported multisensory intervention consists of sessions of standardized, therapist-administered, auditory-tactile stimulation that combines contingent recorded mother's voice delivered using a pacifier-activated system, during holding with supportive tactile containment against the therapist's chest, covered by cloth imprinted with mother's scent. Possible covariates, multi- and uni-sensory processing, will be measured at entry into the study and immediately after the treatment phase. Event-related potential (ERP) testing will be performed prior to the prior to intervention and after intervention is complete, which occurs at 36 weeks postmenstrual age (PMA) on average. ERP testing will take approximately 30 to 40 minutes. All infants will be seen at the neonatal intensive care unit (NICU) Follow-Up Program clinics at 9-12 months PMA (Year 1) and 22-24 months PMA (Year 2), where neurodevelopmental outcomes will be assessed using standardized methods. Parents will also have the opportunity to consent separately to a secondary part to the study in which their infant would participate in one additional ERP testing session in the NICU between 34-36 weeks PMA and one additional visit to the clinical laboratory for ERP testing between 3-4 months PMA. This optional, secondary part of the study is observational only and does not influence randomization for the main trial. For the secondary part of the study, the population will be 40 of the 230 participants. All parents who are approached for the study prospectively and are randomized to control group will be asked if they would like to participate in the secondary part. Enrollment for this secondary part of the study will stop when 40 participants are reached.

Intervention

Behavioral:
• Therapist skin-to-skin Care
Skin-to-skin (STS) holding is part of the multisensory intervention where the therapist will wear a clean 100% cotton T-shirt with a clean hospital gown on top of the shirt and wrap the "kangaroo" positioner securely over the gown. A gauze square scented with parent's skin will be used to provide olfactory stimulation. Therapist STS sessions occur with simultaneous playing of mother's voice contingent on infant pacifier sucking.

Device:
• Contingent parent's voice exposure
The Pacifier Activated Lullaby® (PAL®) device, is a digital music delivery system that integrates a sensor, a pacifier routinely used in the NICU, and a receiver. It delivers a predetermined 10 seconds of recorded parent's voice singing lullabies upon detection of a suck that meets a preset pressure threshold. The original systems were modified for research use by decreasing the lower limit of activation thresholds for delivering the recording. Minimal effort is required to trigger the device. However, the settings ensure that regular attempts are needed to continue to receive continual presentation of the recording of mother's voice by requiring another suck after 10 seconds. The auditory stimulation with PAL will be provided when the infants are still awake (i.e., at the beginning of the session).

Behavioral:
• Parental skin-to-skin care
The standard of care includes parental skin-to-skin care and exposure to parent's voice. During parental skin-to-skin care, infants are placed in a prone position with head positioned over the sternum, allowing transmission of breath and heart sounds to the developing ear. Deeper pressure is applied to offer support and feedback to the child's bottom. Session length is set to a minimum of 45 minutes per unit protocols.

Device:
• Recorded parent's voice
Per standard of care, preterm infants in the NICU currently receive noncontingent recorded parents' voice during two 20 minute sessions per day. Recordings are standardized and are played through a sterilizable device (DINO-egg).

Outcome

Type	Measure	Description	Time frame	Safety issue
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)
