Infants born very preterm (?28 weeks of gestation) are at high risk of having developmental disabilities including cerebral palsy, coordination impairments, attention deficit and learning disabilities. Impairment including reduced postural control, movement variability, visual motor skills, and motor learning are common during the first months of life and are associated with later developmental disabilities. However, infant born very preterm rarely receive evidence based therapeutic intervention in the first months of life when basic science and animal intervention studies suggest the greatest efficacy. Barriers to enrollment in services delay the onset of services and delivery models rarely support targeted preventative intervention or enhanced parent engagement during in the transition from the neonatal intensive care unit (NICU) to home. Targeted intervention supporting postural control and motor learning in the NICU have resulted in short term motor gains. Interventions that enhance parent's ability to read their infant's cues and provide engagement opportunities improve maternal mental health and infant social and cognitive outcomes in the short-term. The purpose of this randomized clinical trial is to evaluate the efficacy of an intervention that combines evidence based motor intervention and parent engagement to enhance the parent's ability to provide daily motor and cognitive opportunities resulting in improved motor and cognitive outcomes. Supporting Play Exploration and Development Intervention (SPEEDI) uses guided participation to empower parents in reading infant's behavioral cues, identifying ideal times for interaction, and enriching the environment and learning opportunities. Parents participate in 5 session in 3 weeks while learning principles of engagement, readiness for interaction, and to provide early motor and cognitive learning opportunities. Parents provide 20 minutes of motor and cognitive play based enrichment daily for 12 weeks with bi-weekly physical therapist support. The parent is empowered to determine the infant's current abilities and advance the activities to the ?Just Right Challenge? throughout the 12 weeks, likely continuing after the intervention. The efficacy of SPEEDI will be assessed in 3 aims: To compare the efficacy of SPEEDI 1) to usual care 2) during delivery at 2 time point; the transition from the NICU to home (around the infant's due date) and beginning at 3-4 months of adjusted age (after the infants due date) 3) for infant who are later diagnosed with Cerebral Palsy and those not Diagnosed with Cerebral Palsy. Ninety infants will be randomly assigned to a Usual Care group, SPEEDI_Early, or SPEEDI_Late group. Group differences will be assessed in developmental outcomes on the motor and cognitive scales of the Bayley Scales for Infant and Toddler Development, Early Problem Solving Indicator, and Gross Motor Function Measure at the end of each intervention period, 12 and 24 months of age. In addition, we will explore a possible mechanism of action, parent's engagement, and the impact of this intervention on the need for later rehabilitation services.
Infants born very preterm (before 29 weeks of gestation) are at high risk of having developmental disabilities including cerebral palsy, coordination impairments, attention deficit and learning disabilities. However, infant born very preterm rarely receives evidence based therapeutic intervention in the first months of life when basic science and animal intervention studies suggest the greatest efficacy. This study will help physicians, policy makers, and parent determine if intervention provided during the transition from the neonatal intensive care unit to home, or the first months at home enhances developmental outcomes and reduces the need for later rehabilitation services.
