Crawling and memory?

If it’s true that we can associate crawling with different types of benefits, a 2007 study (https://www.ncbi.nlm.nih.gov/pubmed/17286842) made the association between crawling and better memory!

9-year old children were assessed in the context of this study. Infants observed an experimenter demonstrate a single target action with a novel object. Their ability to reproduce that action was assessed the next day.

Some infants were tested with the demonstration stimulus in the demonstration context and some infants were tested with a different stimulus in a different context.

Half of the infants in each test condition were crawling while the other half was not.

In the context of these activities, it was shown that the kids who crawled had better retention versus the kids that did not crawl.

We can therefore question ourselves on the nature of cognitive and motor accomplishments. Are they linked because, in the process of motor development, there is activation of the prefrontal cortex, which is both responsible for memory and initiation of movement? Can it be the right left exchanges between the hemispheres of the brain that is accountable for an overall stimulation of the brain, leading to optimization of cortical functions?

Can it be that, clinically, when clients involved in Posturology + Functional Neurology, report having better memory, that it could be because we make them crawl?
