Data Analysis
The data analysis was carried out with IBM-SPSS version 24 statistical
package. Since the variables did not follow a normal distribution,
non-parametric tests were used.
Descriptive statistics and differences between groups in the reflexes
variables were calculated and represented through box plots. The same
was also calculated for MC and the crawling pattern. Secondly, Spearman
correlation coefficients were obtained between every reflex score and
the dimensions and the overall score of the Mabc-2 for both groups.
Finally, Mann-Whitney U test was conducted to determine the differences
between groups regarding reflex inhibition, MC and crawling pattern, as
well as to assess potential gender differences. The effect size was
calculated through r-statistic, using the formula r = Z/√N(N = number of measurements) and it was interpreted according to
the next scale (Coolican, 2009) small (0–0.10), medium (0.10–0.30) or
large (0.30–0.50).
