Current Primary Outcome Measures ICMJE |
Index of Multisensory Processing (IMP) [ Time Frame: At enrollment up to 36 weeks gestation (prior to intervention), and at intervention completion up to 42 weeks gestation ] 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).

Official Title ICMJE | Randomized Controlled Trial to Improve Multisensory Neural Processing, Language & Motor Outcomes in Preterm Infants | ||||||
Brief 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. | ||||||
Detailed 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. |

Study Design ICMJE | Allocation: Randomized Intervention Model: Parallel Assignment Intervention Model Description: 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 protocols (including 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 10 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. Sensory reactivity will be measured at 1 year and language and motor outcomes will be assessed at 2 years. Masking: Single (Outcomes Assessor)Masking Description: Except for parent reports, all measures will be administered by masked examiners. Primary Purpose: Treatment
