Effect of Neonatal Developmental Intervention Program (NDT) on Motor Development and Growth in Premature Infants

ABSTRACT

PURPOSE: The aim of this study was to identify the effects of neonatal developmental intervention program (NDT) in promoting motor development and growth and to determine the usefulness of Hammersmith Neonatal Neurological Examination (HNNE) and Neonatal Behavioral Assessment Scale (NBAS) in premature infants. METHODS: We performed NDT on selected premature infants (PI, n=42) and compared them with the full term control group (FC, n=20). NDT protocol and development assessment (HNNE, NBAS) were manipulated by the physical therapist in the neonatal intensive care unit. The data of this study were collected prospectively. RESULTS: The PI with GA or =34 weeks but less than 37 weeks (LPI) subgroup. The average scores improved significantly in the PI group between the 1st, 2nd, and 3rd assessment by repeated measure (P=0.000). Also, the PI group showed significantly higher total scores and average score at 40 weeks postmenstrual age, P=0.000, respectively than in the FC group. The LPI subgroup showed more weight gain and change in the head circumference between the 1st and 3rd assessment by repeated measure, respectively, P<0.05. The PI group showed no apnea, bradycardia and late sepsis associated with intervention and assessment. CONCLUSION: The NDT might be a safe and useful intervention to promote motor and growth outcomes in premature infants. Also, the HNNE and NBAS might be safe and useful tools for assessing neurodevelopment in premature infants.
