Overview
Overpronation and underpronation describe general foot movements. These terms do not necessarily describe a medical problem with a foot. For example, you can overpronate and not have any problems or symptoms at all. It is important to have your foot structure and symptoms adequately assessed by your prescribing physician and a qualified practitioner such as a Canadian Certified Pedorthist. Once the underlying conditions and mechanical faults are assessed, an appropriate treatment plan including possible orthotic and footwear recommendations can be made.
Causes
There are many biomechanical issues that can contribute to excessive pronation, including weak foot intrinsic muscles, limited ankle dorsiflexion mobility and calf flexibility, weak ankle invertor muscles (e.g. posterior tibialis), weak forefoot evertor muscles (peroneus longus), poor hip strength and control, Anterior pelvic tilting, heel InversionIn a person who overpronates, the heel bone goes into an everted position meaning that it turns out away from the midline of the body. The opposite motion of eversion is inversion. Inversion is a motion that needs to be controlled to prevent the foot from excessively pronating.
Symptoms
If you overpronate, your symptoms may include discomfort in the arch and sole of foot, your foot may appear to turn outward at the ankle, your shoes wear down faster on the medial (inner) side of your shoes. Pain in ankle, shins, knees, or hips, especially when walking or running are classic symptoms of overpronation. Overpronation can lead to additional problems with your feet, ankles, and knees. Runners in particular find that overpronation can lead to shin splints, tarsal tunnel syndrome, plantar fasciitis, compartment syndrome, achilles tendonitis, bunions or hallux valgus, patello-femoral pain syndrome, heel spurs, metatarsalgia.
Diagnosis
If you cannot afford to get a proper gait analysis completed, having someone observe you on a treadmill from behind will give you an idea if you are an overpronator. It is possible to tell without observing directly whether you are likely to be an overpronator by looking at your foot arches. Check your foot arch height by standing in water and then on a wet floor or piece of paper which will show your footprint. If your footprints show little to no narrowing in the middle, then you have flat feet or fallen arches. This makes it highly likely that you will overpronate to some degree when running. If you have low or fallen arches, you should get your gait checked to see how much you overpronate, and whether you need to take steps to reduce the level to which you overpronate. Another good test is to have a look at the wear pattern on an old pair of trainers. Overpronators will wear out the outside of the heel and the inside of the toe more quickly than other parts of the shoe. If the wear is quite even, you are likely to have a neutral running gait. Wear primarily down the outside edge means that you are a supinator. When you replace your running shoes you may benefit from shoes for overpronation. Motion control or stability running shoes are usually the best bet to deal with overpronation.
Non Surgical Treatment
The following exercises help retrain the foot and ankle complex to correct overpronation. Exercises may be performed while wearing shoes, or for an even greater challenge, in bare feet. Duck Stand. This exercise is designed to prepare for the more dynamic BT exercises ahead by waking up the gluteal muscles and teaching clients how the gluteal muscles control the degree of foot pronation. For example, when the glutes contract concentrically, they rotate the leg outward. As the leg rotates outward, the arch of the foot raises (i.e., supinates). Stand beside the BT with both heels together and feet turned outward. (Note: As you progress, perform this exercise while standing on the BT.) Try to rotate legs outward by tightening buttock muscles while tilting pelvis under. As legs rotate outward, arches of the feet raise up out of pronation. Hold position for 30 seconds. Big Toe Pushdowns. This exercise is designed to strengthen the muscle of the big toe that holds up the arch of the foot (i.e., flexor hallucis longus muscle). This stops the foot from overpronating. Stand on top of the BT dome with feet facing forward. Use gluteal muscles to raise the arches of the feet (see previous exercise - "Duck Stand"). Keep arches raised while pushing down big toe into the BT. While pushing down, tension build in the arch on the underside of their foot should be felt. Hold position for 15 seconds.
Prevention
Massage and stretch the calves to increase dorsiflexion at the foot/ankle. Dorsiflexion is the bending at the ankle. By improving the dorsiflexion, one will have more flexibility at the ankle, which will allow the foot to over-pronate less. Massage the IT Band with a foam roller or tennis ball to quiet down the tightness throughout this part of the leg. The IT Band attaches from the glute maximus and runs down the side of the leg into the knee area. When the IT Band is tight it will accelerate the force of the leg moving inward, which will cause the foot to move inward as well. It is often that tightness through the IT Band that promotes over-pronation. 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.
