30. Comparative analysis of reflexes tested in babies immediately after birth

Abstract

Purpose: To examine whether there is a significant difference in the degree of presence between Moro reflex and asymmetric tonic neck reflex in the newborns. Methods: Testing of Moro reflex (MOR) and asymmetric tonic neck reflex (ATNR) was conducted on the third day upon birth in N =100 healthy full-term newborns from regular pregnancies. Each test consisted of three attempts, and it was noted if the reflex is present, incomplete or absent. Testing of MOR and ATNR was carried out by trained medical staff, whereas the examiner performed instructing, observation and data recording. The obtained data were recorded by means of a digital camera, then scored and statistically and descriptively processed. Results: MOR was fully expressed in 52% of examined sample, and in 48% it was incompletely performed. Absence of this reflex was not established in any of the newborn. At the same time, maximal presence of ATNR was noted in 35% of babies, incomplete ATNR was determined in 64%, while the absence of this reflex was registered in 1% of babies. Comparative analysis of average presence of ATRV regarding MOR, confirmed statistically significant greater presence of MOR ( p Conclusion: MOR is significantly more present reflex in newborns compared to ATNR.
