Simply put, over-pronation is an excessive or poorly timed pronation which is part of the regular stride. Pronation is when the foot rolls inwards and the arch compresses as part of your normal walking motion. Pronation is necessary for shock absorption to transmit forces up and down our legs. When someone over-pronates, the foot rolls inwards to a greater degree and the arch flattens: this causes the knee and hip to come out of alignment and reduces the function of all the bones in the feet.
In adults, the most common reason for the onset of Over-Pronation is a condition known as Post Tibial Tendonitis. This condition develops from repetitive stress on the main supporting tendon (Posterior Tibial Tendon) of the foot arch. As the body ages, ligaments and muscles can weaken. When this occurs the job of providing the majority of the support required by the foot arch is placed upon this tendon. Unfortunately, this tendon cannot bear the weight of this burden for too long. Eventually it fatigues under the added strain and in doing so the foot arch becomes progressively lower over a period of time.
People with overpronation may suffer from pain in the knees, hips, and low back. Overpronation itself does not necessarily cause any other symptoms but is a contributing factor of many foot conditions such as Plantar Facsiitis, Heel Spur Syndrome, Posterior Tibialis Tendon Rupture or Tendonitis, Hallux Valgus, Bunion Deformities, Metatarsalgia, Hallux Limitus or Hallux Rigidus, Hammer Toes, and Morton?s Neuroma.
One of the easiest ways to determine if you overpronate is to look at the bottom of your shoes. Overpronation causes disproportionate wear on the inner side of the shoe. Another way to tell if you might overpronate is to have someone look at the back of your legs and feet, while you are standing. The Achilles tendon runs from the calf muscle to the heel bone, and is visible at the back of the ankle. Normally it runs in a straight line down to the heel. An indication of overpronation is if the tendon is angled to the outside of the foot, and the bone on the inner ankle appears to be more prominent than the outer anklebone. There might also be a bulge visible on the inside of the foot when standing normally. A third home diagnostic test is called the ?wet test?. Wet your foot and stand on a surface that will show an imprint, such as construction paper, or a sidewalk. You overpronate if the imprint shows a complete impression of your foot (as opposed to there being a space where your arch did not touch the ground).
Non Surgical Treatment
Side Step with Opposite Reach. This exercise is designed to load the "bungee cord system" of the gluteal muscle and its opposite, latissimus dorsi muscle to keep the foot from overpronating. Because the opposite arm swings across the front leg when walking, this exercise creates tension in the muscles all the way from the front foot, across the back of the hips and back, to the fingers of the opposite hand. Movement Directions. Stand with left foot on top of the dome of the BT. (Note: For added balance, the right foot can tap on the ground, if needed). Reach right leg out to the side of the BT, and tap the ground while squatting down on the left side and reaching right arm across the left knee. Push down with left big toe while squatting. This activates the arch of the left foot and strengthens all the stabilizing muscles on the left side of the lower body. Return to starting position. Perform 8 to 10 repetitions on each leg.
Exercises to strengthen and stretch supporting muscles will help to keep the bones in proper alignment. Duck stance: Stand with your heels together and feet turned out. Tighten the buttock muscles, slightly tilt your pelvis forwards and try to rotate your legs outwards. You should feel your arches rising while you do this exercise. Calf stretch: Stand facing a wall and place hands on it for support. Lean forwards until stretch is felt in the calves. Hold for 30 seconds. Bend at knees and hold for a further 30 seconds. Repeat 5 times. Golf ball: While drawing your toes upwards towards your shins, roll a golf ball under the foot between 30 and 60 seconds. If you find a painful point, keep rolling the ball on that spot for 10 seconds. Big toe push:
Stand with your ankles in a neutral position (without rolling the foot inwards). Push down with your big toe but do not let the ankle roll inwards or the arch collapse. Hold for 5 seconds. Repeat 10 times. Build up to longer times and fewer repetitions. Ankle strengthener: Place a ball between your foot and a wall. Sitting down and keeping your toes pointed upwards, press the outside of the foot against the ball, as though pushing it into the wall. Hold for 5 seconds and repeat 10 times. Arch strengthener: Stand on one foot on the floor. The movements needed to remain balanced will strengthen the arch. When you are able to balance for 30 seconds, start doing this exercise using a wobble board.
