Overview
Pronation is a normal motion which occurs after heel strike during walking. As the foot moves towards toe off, the foot naturally should move from an outside path towards the midline of the body stopping at neutral in ideal conditions. Overpronation is the foot?s motion past neutral and moving excessively toward the bodies midline. Overpronation can be caused by a number of factors including internal rotation of the femur or thigh bone, internal torsion of the tibia or shin bone, being genu valgum or ?knock kneed?, as well as fixed deformities of the ankle and forefoot. The overpronating foot is often hypermobile meaning it has excessive range of motion in the foot joints.
Causes
You do not have to be a runner or athlete to suffer from overpronation. Flat feet can be inherited, and many people suffer from pain on a day-to-day basis. Flat feet can also be traumatic in nature and result from tendon damage over time. Wearing shoes that do not offer enough arch support can also contribute to overpronation.
Symptoms
It is important to note that pronation is not wrong or bad for you. In fact, our feet need to pronate and supinate to achieve proper gait. Pronation (rolling inwards) absorbs shock and supination (rolling outwards) propels our feet forward. It is our body?s natural shock-absorbing mechanism. The problem is over-pronation i.e. the pronation movement goes too deep and lasts for too long, which hinders the foot from recovering and supinating. With every step, excess pronation impedes your natural walking pattern, causing an imbalance in the body and consequent excessive wear and tear in joints, muscles and ligaments. Some common complaints associated with over-pronation include Heel Pain (Plantar Fasciitis) ,Ball of foot pain, Achilles Tendonitis, Shin splints, Knee Pain, Lower Back Pain.
Diagnosis
Firstly, look at your feet in standing, have you got a clear arch on the inside of the foot? If there is not an arch and the innermost part of the sole touches the floor, then your feet are over-pronated. Secondly, look at your running shoes. If they are worn on the inside of the sole in particular, then pronation may be a problem for you. Thirdly, try the wet foot test. Wet your feet and walk along a section of paving and look at the footprints you leave. A normal foot will leave a print of the heel, connected to the forefoot by a strip approximately half the width of the foot on the outside of the sole. If you?re feet are pronated there may be little distinction between the rear and forefoot, shown opposite. The best way to determine if you over pronate is to visit a podiatrist or similar who can do a full gait analysis on a treadmill or using forceplates measuring exactly the forces and angles of the foot whilst running. It is not only the amount of over pronation which is important but the timing of it during the gait cycle as well that needs to be assessed.
Non Surgical Treatment
The following exercises help retrain the foot and ankle complex to correct overpronation. Step Up and Over. This exercise is designed to integrate skills learned in the Duck Stand, Big Toe Pushdowns and Side Step with Opposite Reach exercises to mimic walking and even running. Using the gluteal muscles and big toe in tandem will prevent overpronation while moving back and forth over the BT in a more effective, balanced motion. Movement Directions. Stand with left foot on top of the BT dome. (Note: For added balance, the right foot can tap on the ground, if needed). Extend right foot backwards to the ground and drop hips into a lunge position. Make sure that the right arm rotates across the left leg (this will activate the gluteal muscles on the left side). Now, step through and over the BT into a front lunge with the right leg forward. While lunging forward, the torso and left arm now rotate over the right leg. Throughout the exercise, push big toe down into the BT. Perform 8 to 10 repetitions on both sides.
Surgical Treatment
Subtalar Arthroereisis. The ankle and hindfoot bones/midfoot bones around the joint are fused, locking the bones in place and preventing all joint motion. This may also be done in combination with fusion at other joints. This is a very aggressive option usually reserved for extreme cases where no joint flexibility is present and/or the patient has severe arthritic changes in the joint.
