Objective To integrate therapeutic listening in early comprehensiveintervention of premature infants and observe its effects on motor function after corrected age of 1 year old.
Methods 186 premature infants who visited high-risk infant outpatient clinic of Nantong Maternal and Child Health Hospital from January to December 2019 were recruited as study subjects. They were randomly divided into two groups by random number table, 93 cases in each group. Both control and intervention group received routine physical examination, early comprehensive intervention and regular follow-up (once a month). The intervention group was additionally treated with therapeutic listening twice a day for 15 minutes each time, and the whole intervention period lasted for 3 months. All premature infants received intervention at the outpatient follow-up after discharge at the time of corrected age of 1 month. Physical development measurements, Test of Infant Motor Performance(TIMP), Gesell Development Scale and Peabody-2 motor Development Scale were performed before intervention and 3 months after intervention. They were assessed by physical development measurements, Gesell Development Scale and Peabody-2 motor Development Scale again 11 months after intervention.
Results There were no significant differences in physical development measurement, TIMP, Gesell development scale and Peabody-2 motor Development Scale between the two groups before intervention(all P > 0.05). The results of TIMP in both groups were improved 3 months after early comprehensive intervention, but intervention group was better than control group (all P < 0.001). The results of One-Way repeated measure analysis of variance showed that the ability zone development quotient of Gesell developmental scale and Peabody-2 motor development scale increased in both groups after early intervention (all P < 0.05). Multivariate analysis of variance showed that the developmental quotient of Gesell's gross motor and fine motor areas, and developmental quotient of all Peabody-2 ability areas in the intervention group were higher than those in the control group 3 and 11 months after intervention (all P < 0.05).
Conclusion Early comprehensive intervention can improve motor function of premature infants. Early intervention integrated with therapy listening is helpful to improve motor function of premature infants.
