From human body physiology point of view the feet carry out one of the most important functions – pump function. Two types of circulation, blood circulation and lymph circulation, are the base for the following processes: first one – alimentation and nutriment, while second one – secretion of decay and disintegration products. These processes sustain the cellular metabolism and cells energy condition. 96% of all work in blood circulation system and 100% of lymph outflow are produced by body’s skeletal muscles.
One of the most important conditions to sustain effective lymph and blood circulation is proper gait biomechanics, i.e. the nature-established sequence of muscles contractions. The described biomechanics couldn’t be in place if feet arches are deformed or footwear is manufactured with mistakes. Just making footsteps shuffling your legs does not mean the proper gait procedure.
There exist five gait phases: first one is heel bone bearing support, and last – so called “rift-over” and push with toes. These phases define kinematics of skeleton elements movement and kinematics of muscles contraction. Every muscle contraction squeezes the definite vein segment, pushing off the blood portion in the direction of the heart. In case if even one phase of gait’s period is absent for some reason, fluency and integrity of blood stream movement become disrupted. Thus zones of increased pressure emerge, inside which the veins are stretched, strained and protracted.
The largest blood portions are pushed out at the moment of subtalar joint pronation (inner arch descends) and in the phase of intensive toes push. The strongest muscles of human body are involved in theses phases. If a person has flat feet diagnosis, the shock-absorption amortizing function and pump function of the feet are substantially disrupted (notice: the air gap under arch decreases; as for users of rigid orthotics – this gap is nonexistent). The real objective for orthotics must be the following: to help weak muscles to master excessive loading and therefore to enforce and sustain their efficiency.
Consider varicoses veins dilatation – first of all, this means defection in gait’s biomechanics. Veins surgical incision does not improve blood circulation. And in same way, impairment in arterial blood flow (diabetic angiopathy) takes place because of disturbances in venous outflow. Consider our recent case: the male patient (from Berlin) who suffered from diabetic angiopathy. He already had feet cyanosis (blue spots), and he was under preparation to amputation of both feet. We provided him with properly manufactured orthotics bio-podocorrectors, and barely after 20-30 minutes of walking he reported that pain has gone and it is much easier for him to walk. In a week’s time the possibility of amputation was dropped, in 8 months time he was not in “diabetic stock-list” any more, blood’s sugar content came to normal.
Analogical situation is observed with heart diseases, with lower limbs swelling. Therefore, all the efforts over feet correction must be considered as objective of organism blood circulation normalizing.
