Over Pronation and Pronation
Pronation is the normal movement of the foot that is necessary in order for the foot to absorb the shock of ground impact and also to adapt to uneven terrain. During the movement described as pronation the foot rolls in slightly towards midline of the body.
Over pronation and excess pronation are terms used to describe the abnormal motion of the foot when it rolls towards the midline of the body too far or at an irregular time during walking. Abnormal pronation is one of the most common mechanical causes of pain in the foot.
When the foot over pronates the foot rolls towards the midline of the body and the arches are placed under increased strain and collapse. During this arch collapse the ligaments, tendons, joints, and muscles of the foot are strained under the excessive load. It is this subtle repetitive stress placed on the joints, tendons and ligaments that over time, small stress compounded by small stress, that causes injuries that are best described as overuse injuries. These make up a large group of modern day foot injuries.
Early signs of over pronation related foot problems are muscle fatigue when walking or standing and tired aching legs. In young children some of the early signs of over pronation are not wanting to walk and always wanting to be picked up and carried.
The appearance of over pronation is a drop in the height of the medial (inside) arch of the foot and a rolling of the foot towards the mid line of the body. In some severe cases there is a complete flattening of the medial (inside) arch of the foot
The symptoms of over pronation may differ depending on the extent of the underlying problem, the age of the person and also the activity level of the individual. Some of the most common foot pains caused by pronation are.
Iliotibial band pain / Lateral (outside) knee pain, Children’s PainOsgoodschlatters Syndrome), Bunions (Hallux Abducs (Severs Disease/ to Valgus), Tired Aching Legs, Flat Feet/Collapsed Arches, Shin Pain, Metatarsalgia / Ball of Foot Pain / Mortons Neuroma, Lower Back Pain, Knee Pain, Heel Pain/Plantar Fasciitis/Heel Spur
Ergonx Orthotic innersoles are used to stop excessive pronation by supporting the foot and preventing arch collapse. Ergonx innersoles are an instant method to reduce over pronation and overuse related foot pain.
