Motor Competence
Table 2 also contains the descriptive statistics of the scores obtained
by both groups in the Mabc-2 battery, and the differences between them.
Statistical correlations were calculated in every group (Table 3) to
determine the association of primary reflexes scores with Total MC and
with the Macb-2
dimensions.
———————————-Table

In group A, negative and statistically significant correlations were
found between the overall score of the Macb-2 battery and the reflexes
ATNR and MR. In addition, significant correlations were obtained between
MR and STNR reflexes and manual dexterity.
In
group B, negative and statistically significant correlations were found
between the overall score of the Macb-2 battery and all the reflexes
assessed. These results seem to indicate inverse association between
variables. Only ATNR reflex showed a positive association with aiming
and catching (r = 0.36), which should not be disregarded.
Crawling Pattern
The Table 4 shows the scores obtained for every reflex measured,
differentiating between those participants who had crawled and those who
had not.
—————————————Table
4————————————
Significant differences were found in all the reflexes, with small
effect sizes between children who had developed the crawling pattern and
those who had not.
Besides, Mann-Whitney U test was conducted to analyze the differences in
the Mabc-2 battery scores between children who had developed the
crawling pattern and those who had not (Table 4). Statistically
significant differences were found, with medium effect sizes, in all
dimensions and in the overall score of the Mabc-2 between children who
had developed the crawling pattern and those who had not.
Finally, in group A, 91.1% of children had not developed the crawling
pattern, while in group B only 37.5% had not crawled. When comparing
between groups, significant differences were obtained in this variable
(U = 334.000, p < .001).
