Hyperpronation (Lowering of Arches) of the Foot
Hyperpronation is very widespread and can be found in millions of Russians. In order to understand the condition better we will review the 3 most widespread types of feet.
70% of the population have arch lowering. Only 20% of the population have healthy feet. And only 10% have obvious foot deformities, i.e. either they have obvious flat-footedness or on the contrary – very high arches (hollow feet).
1) Flat-footedness (Pes Planus)- 5% of the population
Flat-footedness indicates foot splaying and the sole surface fully adjoins the surface under the load. Genuine flat-footedness is really rare. In fact less than 5% of the population don’t have a foot arch. It is quite normal for preschool-age children: as they grow up, their foot arches start forming.
2) Hollow feet (PES Cavus) - 5% of the population
It is an inborn pathology and quite a rare one. It can be found in 5% of the Russian population. As opposed to flat-footedness, the arch is very high even under the body weight. Due to this condition ligaments and muscles get very rigid which hampers the natural cushioning of the foot, pronation and supination.
3) Lowering of the longitudinal arch - 70% of the population
Most of us have lowering of the foot. It seems quite normal with obvious (but low) arch especially while sitting.
When we are standing, the position changes under the body weight, the arch height lowers, the foot is splayed, while the leg rotates inwards. This position is called hyperpronation or arch lowering.
It is not on the whole a pathology but we need supination and pronation as these actions are constituent parts of our gait. The interior arch performs the cushioning function and supination (exterior arch) helps provide propulsion.
Возникает в следствие длительной, ”глубокой” пронации, которая не даёт стопе шанс “восстановиться” и супинировать.
It forms due to long-term deep pronation which doesn’t let the foot restore and supinate.Thus all of this hampers our natural gait and as a result the imbalance causes modifications in the proximal joints.
Your shoes get worn on the outside?
Many people notice that their footwear gets worn on the outside edge. And they think this is because of low supination i.e. they think their feet careen outwards and not inwards. However in the majority of cases this is not so. The majority of people first of all load the exterior part of the foot and then roll their feet inwards. That’s why don’t get confused by uneven wear of your shoes…
If you have regular flat-footedness or hollowe feet, in both cases irregular gait can cause a number of various complaints. By aging non-physiological position of the foot can lead to pain in the heel and knee.
The condition can be a consequence of the following factors: obesity, pregnancy, age or repetitive collisions with a rigid surface which can weaken the arches and cause hyperpronation. Hyperpronation is often found in sportsmen especially in runners. Nowadays most of them use individual insoles and orthopedic footwear.
