Effect of neonatal therapy on the motor, cognitive, and behavioral development of infants born preterm: a systematic review

摘要

Aim To synthesize the existing literature and determine the efficacy of neonatal therapy, starting in the neonatal intensive care unit (NICU), on the motor, cognitive, and behavioral outcomes of infants born preterm. Method Databases were searched for randomized controlled trials or quasi‐randomized controlled trials of direct therapy early intervention for infants with a gestational age of less than 37 weeks, initiated in the NICU and delivered by a therapist or parent with therapist support. Quality was evaluated using the Cochrane standardized risk of bias assessment tool. Recommendations were made using the Grading of Recommendations, Assessment, Development and Evaluations approach. Results Fifteen studies met the inclusion criteria. Studies were categorized into four intervention categories: (1) parent‐delivered motor intervention (PDMI); (2) therapist‐delivered postural control intervention?(TDPCI); (3) developmental care; and (4) oromotor intervention. Risk of bias varied from low (10 studies) to high (three studies) or was unclear (two studies). Interpretation Preliminary support indicates that daily PDMI improves motor and cognitive outcomes in the short‐term and possibly long‐term. TDPCI is effective in promoting short‐term gains in motor development. Developmental care programs designed by a neonatal therapist appear to be effective in improving short‐term behavior but are inconclusive for motor and cognitive outcomes or long‐term behavioral outcomes. Regarding oromotor interventions, there is insufficient research to be confident in their efficacy on improving developmental outcomes. What this paper adds Parent‐delivered motor interventions (PDMIs) are more effective in improving motor and cognitive outcomes than other interventions. Preliminary support indicates that daily PDMI improves motor and cognitive outcomes in the short‐ and possibly long‐term. Therapist‐delivered postural control interventions are effective in promoting short‐term gains in motor development. Developmental care programs designed by a neonatal therapist are effective in improving the short‐term behavior of infants born preterm. Oral motor interventions were found to have no effect on improving developmental outcomes.
