Over-pronation, or flat feet, is a common biomechanical problem that occurs in the walking process when a person?s arch collapses upon weight bearing. This motion can cause extreme stress or
inflammation on the plantar fascia, possibly causing severe discomfort and leading to other foot problems.
Over-pronation occurs when the foot collapses too far inward stressing the plantar fascia (the area underneath the arch of the foot.) Normally, one pronates every time he or she walks, but excessive
pronation is called over-pronation. When this occurs it can cause pain in the feet, knees, hips, low back and even the shoulder. Decreasing over-pronation, which is very prominent in runners, will
help add endurance, speed and efficiency to your run and ultimately place less stress on your body.
Due to the laxity of the soft tissue structures of the foot, and the fact that the joints are not held together properly, the bones of the feet shift. When this occurs, the muscles that attach to
these bones must also shift, or twist, in order to attach to these bones. The strongest and most important muscles that attach to our foot bones come from our lower leg. So, as these muscles course
down the leg and across the ankle, they must twist to maintain their proper attachments in the foot. This twisting of these muscles will cause shin splints, Achilles Tendonitis, generalized
tendonitis, fatigue, muscle aches and pains, cramps, ankle sprains, and loss of muscular efficiency (reducing walking and running speed and endurance). The problems we see in the feet, which are due
to over-pronation include bunions, heel spurs, plantar fasciitis, fallen and painful arches, hammertoes, metatarsalgia (ball of foot pain), and calluses.
When sitting, an over-pronating foot appears quite normal, i.e. showing a normal arch with room under the underside of the foot. The moment you get up and put weight on your feet the situation
changes: the arches lower and the ankle slightly turns inwards. When you walk or run more weight is placed on the feet compared to standing and over-pronation will become more evident. When walking
barefoot on tiles or timber floors over-pronation is more visible, compared to walking on carpet or grass.
Non Surgical Treatment
Mild cases of Overpronation may be controlled or corrected with a supportive shoe that offers medial support to the foot along with a strong heel counter to control excessive motion at the heel
starting with heel strike. In mild cases with no abnormal mechanical pressures, an over the counter orthotic with heel cup and longitudinal or medial arch support to keep the foot from progressing
past neutral may help to realign the foot. A Custom foot orthotic with heel cup and longitudinal arch support to help correct position of the foot as it moves through motion. Heel wedges may also
assist in correcting motion.
Pronation forces us to bear most of our weight on the inner border of our feet. Custom-made orthotics gently redistributes the weight so that the entire foot bears its normal share of weight with
each step we take. The foot will not twist out at the ankle, but will strike the ground normally when the orthotics is used. This action of the custom-made orthotics will help to prevent shin
splints, ankle sprains, knee and hip pain, lower back pain, nerve entrapments, tendonitis, muscle aches, bunions, generalized fatigue, hammer toes, and calluses.
