Abstract
Using the laser Doppler method (LDF), the degree of variability of blood microcirculation and microvascular reactivity in the foot was studied in 40 young people with varying degrees of flatfoot. In order to identify the reactivity of microvessels in foot, the microcirculation indicators were recorded at rest (at lying position) and during the postural test (with the leg hanging down). It has been established that in individuals with an average height of the foot arch, the microcirculation intensity and the microvascular reactivity of the foot skin are balanced under load. In the case of a high-arched foot, there is an increase in blood perfusion of tissues and a tendency to an increased activity of microcirculation regulatory mechanisms. With the depletion of the myogenic mechanism of regulation of microcirculation, the activity of the neurogenic mechanism was identified increasing. In the case of low-arched foot and flatfoot, there is a decrease in blood flow in the microvessels of the sole. This may be due to a decrease in intravascular resistance and an increase in the myogenic tone of microvessels. In individuals with flatfoot, the microvascular reactivity in the sole of the foot significantly decreases. The decrease in microvascular reactivity in flatfoot reduces the ability of its adaptation to different functional conditions.
