A non-controlled, prognostic cohort study was performed with the aim of establishing markers of neurological development and defining a clinical and epidemiological profile of preterm newborns at 3, 6, 9, and 12 months of gestation-corrected age in terms of parachute and lateral propping reactions. Newborns with gestational age of up to 36 weeks and 6 days, weighing 2,000 g or less at birth, were included in the study
At 6 months of age, parachute and lateral propping reactions were present in 8.1{f607f86846ba214ecc118a24d8f221d0f6091e2f284aa65c23a2cf36879dc8e8} of the patients. At 9 months, the parachute reaction was present in 87.5{f607f86846ba214ecc118a24d8f221d0f6091e2f284aa65c23a2cf36879dc8e8}, and the lateral propping reaction was present in 90{f607f86846ba214ecc118a24d8f221d0f6091e2f284aa65c23a2cf36879dc8e8} of the children. It was possible to assess parachute and lateral propping reactions in preterm children in the first year of life. Alterations in trunk-limb coordination may be evidenced in the 1st year of life through postural reactions, which are maintained as prematurity markers until school age.
