ASH has a high prevalence rates and considered one of the major modifiable risk factors for
cardiac vascular diseases (CVD) and brain vascular diseases (BVD) and one of the most
important public health problems. Researches estimated 62% of BVD can be attributed to ASH.
In Brazil, prevalence of hypertension ranged from 21.6% in 2006 to 42.4% in 2011. CVD are
responsible for high frequency of hospitalization, and in 2009, 91,970 hospitalizations due
to CVD cost public treasury more than 165 million reais. ASH neurological pathophysiology
studies has shown that excessive activation of sympathetic autonomic nervous system (SANS)
seems to have an important role in genesis and maintenance of ASH, with current studies aimed
to understand this relationship.
Pathways used by SANS for immediate control of BP (wich are reticulate formation, bulb and
cortex) appear to be similar to pathways used for postural control reflex (reticulate
formation, bulb, cortex, among others), which are also used by Postural Reprogramming Insoles
(PRI) for posture adequacy. Due to this similarity in reflex activation areas, it is believed
that PRI may have some effect on BP regulation.
There are many ways to treat postural changes and one of them is posturology, which is based
on therapeutic use of postural reprogramming insoles (PRI). PRI activates tonic-postural
system, rebalancing muscles, joints and bony structures of body segments, and returning
individual to an appropriate posture.
The PRI is composed of a central artifact, situated in reflex zone full of somatosensory
stimuli captors, which generates a frequency of vibration that promotes postural adaptation.
