Eye movement is quite an important component of Posturology. It is the reflection of a neurological reality where it is that both eyes move as one unit to focus on a given target.

In the context of Posturology, we study eye movement and we associate the findings with the position of the head, at rest. When eye movement is weak, head position on the shoulders is often altered.

Since this eye tracking business originates in the brain, it is possible that it could be studied to diagnose cerebral problems.

As far as autism is concerned, Jennifer Wagner, a researcher at the Boston General Hospital, studies eye movement in babies to discern which ones are at risk of developing autism. Preliminary results suggest that, at around 9 months of age, for the child at risk, the baby’s pupil dilates more when looking at emotional faces, suggesting that these babies are more so stimulated by emotional content.

The study of ocular movement could allow us to distinguish between ADHD and fetal alcoholism syndrome, for example. Lauren Itti, of the University of South California, stipulates that children affected by fetal alcoholism syndrome observe the orientation of objects and contours differently.

Itti indicates that ocular movement can also be useful in the diagnostic of schizophrenia. She finds that schizophrenics have a difficult time pursuing an object.

On May 21, 2016, in the journal Biological Psychiatry, researchers have indicated that, via ocular movement tests, we were able to differentiate between schizophrenics and healthy individuals in 98% of the cases.

This all being said, in the context of Posturology, one can wonder how far it goes when we get eyes to coordinate and that we favor better neurological organization!

It would be easy to think that, if we experience pain, it is because a tissue is suffering from a lesion. We can think of an injury, weak or tight muscles.

We now know that it’s not that simple, especially when pain becomes chronic. We speak of chronic pain when it’s been ongoing for more than 3-6 months.

If injuries hurt, it’s because they activate nociceptors. These are the receptors that respond to pain or excessive temperatures.

Recent studies allow us to understand that it’s possible to have pain while there is actually nothing wrong happening with the physical body.

Here are some examples that make you go hmmm:

– Researchers that have analyzed MRI’s of the spinal column of asymptomatic patients found that 80% of them had a disc protrusion or a hernia.
– Researchers have analyzed MRI’s of subjects that were asymptomatic and, in 34% of the cases, they presented with one or more than one tear of the rotator cuff muscles. When a population of individuals 60 years old and more were studied, this number was 60%.
– In the context of subjects presenting with arthrosis of the knee, it was found that 76% of them had lesions at the level of the menisci. They were asymptomatic.

Taking these facts into consideration, how is it that we are told that, to experience pain, something has to be broken?

Professor Lorimer Moseley, teacher of neurosciences and responsible for the department of physiotherapy at the University of South Australia, stipulates that pain is the sum of the environmental context. If it’s true that the pain signal is activated when we get hurt, it’s also true that our environment is a component of our perception of pain.

Professor Dr. Finn Bojen-Moller has even stated that it was fundamental that pain be felt before tissue is actually hurt. He actually sees pain as an alarm signal whose purpose is to maintain a certain level of integrity of the tissues of the organism.

The perspective illustrated is the perspective of practitioners that base their work exclusively on what is seemingly published in the literature. I don’t think that they are wrong. But I am not convinced they are absolutely right either.

What these professionals are saying is that the body can adapt to stress. It would be for that reason that there is no point in trying to reduce stress on the body by aligning it since it has a capacity to buffer it. Only thing is: adaptation does have its limits. Here is a recent study that states that the link between structural damage and pain: https://www.ncbi.nlm.nih.gov/pubmed/26359154.

With this in mind, we dispose of the technology and exercises to align the bony pieces of an individual without them having to think about it 24/7. It can be an interesting option to reduce constraints on joints, decrease muscle stiffness and allow for optimal performance.

 

MRI Findings of Disc Degeneration are More Prevalent in Adults with Low Back Pain than in Asymptomatic Controls: A Systematic Review and Meta-Analy… – PubMed – NCBI

A fascinating study from Yale University could motivate you to read more!

3635 subjects of 50 years or older were studied over a period of 12 years.

We classified these subjects in 3 categories:

• Those that do not read at all
• Those that read 3.5 hours and less per week
• Those who read 3.5 hours and more per week.

The results are mind blowing!

Individuals that read live 2 years more than individuals that do not read.

Individuals that read more than 3.5 hours per week see the likelihood of actually dying reduced by 23% versus the ones that do not read.

The individuals that read up to 3.5 hours per week have 17% less chances of dying as compared to the ones that do not read.

How so, do you ask?

We know that reading increases connectivity between different areas of the brain and we also know that reading increases empathy.

What the study does not stipulate is whether or not the subjects that were studied possessed good eye movement.

It would be interesting to calibrate posture of the individuals studied, which is known to improve eye eye coordination, amongst other factors.

We know that, to coordinate eyes, whether it is for pursuits or saccades (both are needed for reading), optimal connectivity between the brain hemispheres is great.

That is one of the objectives with posturology!

If certain social situations are easily identifiable as good or not, some are less obvious. For example, if a comment is made with cynicism, it can be hard to interpret the nature of the comment. As well, the tone of voice can change the intention of the words that are pronounced.

Recently (2016), researchers found tow areas of the brain responsible for the identification or what’s good and what’s not so good, when the situation is ambiguous.

The inferior parietal lobule (a part of the parietal lobe) has been identified for the identification of negative situations while the superior sulcus of the temporal lobe has been identified for recognition of positive events.

As well, we recognize that these two areas of the brain speak to each other in order to coordinate the final response to an event.

Upon realizing that the parietal lobe is, amongst other things, the area for integration of incoming stimuli (skin, muscles), is it possible that an imbalance in how feet tough the ground, for example, would be associated with a deficit in how this area works as a whole?

And if such was the case, this could mean that our foot stance, our posture, affects our capacity to judge situations in our everyday lives…

We all know it: exercise is good for us… and it’s good for our brain! What recent studies have shown is that specific forms of exercises are better for specific parts of the brain.

Physical health is not only good for the brain; it’s also been proven that it’s good for reducing the effects of such illness as dementia, Parkinson’s and depression.

To be more precise, we have studied high intensity intervals, aerobic activity, muscular conditioning, and yoga as well as sports sequences.
It was 15 years ago that, for the first time, we concluded that exercise affected the brain. Mice, while running, were forming new neurons in the hippocampus, which lead to an improvement in memory.

We then wanted to know if the type of exercise selected for a specific population had different effects. We compared muscular conditioning and fast walking. After 6 months, both groups showed better spatial memory.

More specifically, the group that was involved in muscular conditioning saw its executive functions improve significantly. These subjects had also seen gains in associative memory.

Those involved in fast walking saw results in verbal memory.

Only stretching as an isolated activity showed not improvement in any of the cognitive measures.

Learning sports sequences develops attention gradually over a longer period of time.

What’s also been found is that children that are healthy show both hippocampus and basal ganglia of greater size. When one considers that basal ganglia allow us to turn thoughts into things, it’s a very cool side effect of being fit!

What needs to be added to all of this is that, if in the context of performing these activities, the body is aligned and stable; it is better at both proprioception and exteroception.

Proprioception is being to feel its own body whereas exteroception is being able to feel the environment around us. Posturology improves both simultaneously, which allows for maximal brain stimulation!
