Overview
Brief Summary
The aim of this study is to analyze the effect of preterm gestational age, birth weight and perinatal risks factors on gross motor development of preterm infants.
We will compare the data of infants evaluated by the Alberta Infant Motor Scale (AIMS) and the Perinatal Risk Inventory (PERI) in an Infant Development and Early Intervention Center (IDEIC).
Detailed Description
An assessment of the infants' gross motor development will be carried out at admission, of IDEIC following the AIMS scale and bearing in mind their corrected age. Importantly, the trimester according to their corrected age was also recorded.
The gestational age of each infant will be recorded and used to group participants according to the following classification: late preterm newborn infant (LPNI; born between 34+1 and 36+6 weeks of gestation); moderate preterm newborn infant (MPNI; born between 32+1 to 34 weeks of gestation); very preterm newborn infant (VPNI; born between 28 to 32 weeks of gestation); and extreme preterm newborn infant (EPNI; born before 28 weeks of gestation).
The birth weight will be recorded and the infants will be grouped according to the following classification: newborns with adequate birth (birth weight of >2500 g), low birth weight (LBW; <2500 g and >1500 g); very low birth weight (VLBW; <2500 g and >1000 g), and extreme low birth weight (ELBW; <1000 g).
The infants will be assessed by the PERI test accounting for their discharge medical records. The infants will be then classified according to the biological risk level, in low, moderate and high risk.
Both the PERI and the AIMS test were assessed by three physiotherapists from the IDEIC with 10 to 20 years of experience.
Afterwards data will be analyzed using the Statistical Package for the Social Sciences Statistics (IBM SPSS) software for Windows version 22.0.
From all data collected as described in the brief summary, descriptive analysis and correlations between variables will be performed.
Samples will be classified using descriptive and frequency analysis. One-factor ANOVA, bivariate correlations will be carried out. Correlations between variables will be evaluated using Pearson's coefficient (bivariate correlation) or Spearman's coefficient (rank correlation). Frequencies analysis, square Chi test and backwards regression analysis will be used when appropriate.
AIMS direct scores will be standardized by converting them into Z scores. AIMS standard mean and deviation by age and gender will be used.

Outcomes
Primary Outcomes
Gestational age
Time Frame: Day 1
Gestational age at birth. This information will be extracted from their discharge medical records
Perinatal Risk Inventory (PERI)
Time Frame: Day 1
The PERI is a test designed to assess neonatal situation, prior to infants' discharge from the hospital at birth that determines the possibility of abnormalities or pathologies in the infant' development at very early stages. Its predictive value is greater when it reaches a score equal or superior to 10. The infants will be assessed by the PERI test accounting using their discharge medical records.
Alberta Infant Motor Scale (AIMS)
Time Frame: Baseline
The Alberta Infant Motor Scale (AIMS) is an observational scale to assess infants' gross motor development from birth to independent walking. The test consists of 58 items based on descriptions of the postural control in supine (9 items), prone (21 items), sitting (12 items) and standing (16 items) position. Each item scores one point, therefore the maximum puntuation possible is 58 points and the minimum 0 points. The greater the puntuation, the better is their motor development. It is conceived for infants from 0 to 18 months old. The test provides information about the infant's motor activities and allows the measurement of motor activity development over time or before and after therapy. The infants' assessment needs to take place in a quiet environment with minimal handling and without stimuli or random help. An assessment of the infants' gross motor development will be carried out at admission, following the AIMS scale and bearing in mind their corrected age.
Birth weight
Time Frame: Day 1
Weight that preterm infant had at birth. This information will be extracted from their discharge medical records
