- Brief Summary
The investigators are conducting a two-site randomized control trial with the aim of defining the impact of music (M) without or with parent voice (MPV) on very preterm infants' acute and cumulative stress, intranetwork connectivity on term brain MRI, and language and other neurodevelopmental outcomes at two years corrected age. This is based on the hypothesis that infants in MPV arm are expected to experience the greatest benefit compared with infants receiving standard care.
- Detailed Description
Preterm birth remains the leading cause of death for children under five. For survivors, it also accounts for high morbidity and substantial physical, psychosocial, emotional, and financial burden for individuals, families, and communities. The impairments span over multiple domains, with language difficulties affecting about half of surviving children. Evidence indicates that preterm birth has significant impacts on long-term functioning, yet primary prevention of preterm birth is presently not feasible. It is therefore imperative to prioritize early interventions to mitigate these adverse long-term effects on child and family outcomes.
Very preterm (VP) infants, i.e., those born below 32 weeks gestational age (GA) typically spend 2-4 months hospitalized in the Neonatal Intensive Care Unit (NICU) before reaching term-equivalent age (TEA). During this time, the preterm brain nearly quadruples in volume and is highly sensitive to both positive and negative environmental experiences. Yet, during this period, VP infants must also receive life-saving intensive medical care in the sensory-atypical environment of the NICU. From an auditory perspective, this atypical environment comprises loud equipment sounds at volumes far exceeding recommended levels, silence, and a paucity of human interaction. One domain of neurosensory experience is the auditory environment, comprised predominantly of non-meaningful, high-frequency/ high decibel equipment sounds, and silence. The deprivation of VP infants from enriching auditory experiences (parental voice, infant-directed language) combined with the constant influx of high frequency/high decibel sounds (alarms and electronic noise) can induce chronic stress and negatively impact auditory and other areas of cortical development.
For preterm infants who have not yet reached term-equivalent age (TEA), the NICU hospitalization is a critical window for developmental adaptability to experience during a highly sensitive period of brain development. There are two key pathways whereby music and voice therapy in the VP infant are thought to have benefit - stress reduction and auditory enrichment. Recent work indicates that music therapy may reduce the immediate stress experienced by VP infants, with evidence emerging on its impact to improve neurodevelopmental outcomes. Prior studies have been limited due to small size, variability of music exposures, inconsistent study design and outcome measures. Further, most studies explored exposure-outcome associations, without mechanistic investigation. One study showed improved white matter maturation in acoustic radiations, larger amygdala volumes, and enhanced functional connectivity brain magnetic resonance imaging (MRI) after early music exposures. These suggests that early music exposure may enhance auditory cortex development and reduce stress (amygdala) in VP infants.
While small studies inform these hypotheses, a large, randomized trial is necessary to test them more rigorously. Our own center's pilot study demonstrated that a music condition with low, repetitive, and rhythmically consistent entrainment stimulus was associated with improved physiologic state after the exposure. Based on these data, the investigators plan to further develop an individualized intervention encompassing evidence-based musical elements onto which parental voice will be carefully layered. The aim of this proposal is to conduct a randomized trial to determine the effects of a protocolized music-based intervention (MBI) with and without parental voice on stress reduction, early brain structure and function, and neurodevelopmental outcomes.
The investigators propose to address this knowledge gap in a large, two-center randomized controlled trial (RCT), employing a novel MBI tailored based on available preliminary data and inclusive of musical and non-musical elements to facilitate parent engagement, with comprehensive evaluation of relevant clinical, neuroimaging, and neurodevelopmental outcomes of VP infants up to two years of age. The impact of this work will be two-fold: this proposal will 1) generate rigorous evidence to specifically support the integration of music medicine as a therapeutic approach for VP infants in the NICU, and 2) strengthen the evidence base for neurosensory interventions for hospitalized infants, which will shift the framework of care in the NICU by leveraging developmental care interventions to optimize the outcomes of VP infants.

Group Intervention Description Music Music We will create three recordings with increasing complexity for each infant. For each infant developmental stage (32, 34, 36+ weeks PMA), Music Therapists (MTs) in both units will present parents with a curated list of 8-10 musically comparable, familiar lullabies to select from. Songs will be available in different languages reflective of patient diversity, with rhythm, tempo, pitch range/ change, instrumentation, melody, harmony selected drawing on available evidence, including BWH NICU pilot data. Timing: MBI to be administered after regular NICU "care and feeding" times, which are typically considered stressful times for infants. The goal of the intervention will be to provide a calming and relaxing experience to the infant as they "settle" back to sleep after handling times. Music delivery will occur via infant-adapted headphones to facilitate blinding. Music and parent voice Music and parent voice The selected lullabies will be pre-recorded by the MT as described above to include a guitar accompaniment track, and a separate vocal track with the MT singing along, in two separate keys to allow variation for parent voice range and comfort. Parents will be invited to sing along with the recorded track of MT singing, and MT will later remove the MT-voice recording track so only the parent voice will be heard with the guitar in the final recording. Timing: MBI to be administered after regular NICU "care and feeding" times, which are typically considered stressful times for infants. The goal of the intervention will be to provide a calming and relaxing experience to the infant as they "settle" back to sleep after handling times. Music delivery will occur via infant-adapted headphones to facilitate blinding. Reference/ Standard of care Standard Care These are infants recruited in the study who will receive the unit standard of care. They will be listening to the NICU ambient noise via infant-adapted headphones but will not receive any music intervention.
