What Does Over-Pronation MeanOverview
Overpronation still continues to be misused and misunderstood. For example, there was a study that got a lot of recent mileage in the mainstream media and the blogosphere that claimed to show that foot pronation was not associated with injury risk. It was intriguing following comments on the study in mainstream media and in social media, especially the parroting of the press release without any critical appraisal. The study actually eliminated the ?overpronators? that were probably at high risk from the study then found that ?overpronation? was not a risk factor. What is more intriguing was that there was another study from around the same time that found the exact opposite. Clearly, the data on ?overpronation? and risk for injury in runners is mixed, so we need to rely on the more formal systematic reviews and meta-analyses of all the data. The most recent one of those concluded that ?overpronation? is just a small risk factor for running injury risk, but it is still statistically significant.
Although there are many factors that can contribute to the development of these conditions, improper biomechanics of the body plays a large and detrimental role in the process. Of the many biomechanical elements involved, foot and ankle function perhaps contribute the most to these aches and pains.
Not all foot injuries affecting runners are necessarily down to a particular running gait; it is rarely that simple to diagnose how a foot problem developed . Simply being an overpronator does not mean that a foot injury has been caused by the running gait and it could be due to a number of factors. However mild to severe overpronators tend to be at a higher risk of developing musculoskeletal problems due to the increased stresses and strains which are placed on the body when the foot does not move in an optimum manner. The following injuries are frequently due to overpronation of the feet. Tarsal tunnel syndrome. Shin splints. Anterior compartment syndrome. Plantar fasciitis. Achilles tendonitis. Bunions. Sesamoiditis. Stress fractures. Back and hip pain. Ankle pain.
When you overpronate your foot rolls inwards causing the lower leg to rotate inwards too. It's thought that this increases stress on the soft tissues of the lower leg causing pain and inflammation, or more commonly known as shin splints.
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.
Firstly, a thorough and correct warm up will help to prepare the muscles and tendons for any activity or sport. Without a proper warm up the muscles and tendons around your feet, ankles and lower legs will be tight and stiff. There will be limited blood flow to the lower legs, which will result in a lack of oxygen and nutrients for those muscles. Click here for a detailed explanation of how, why and when to perform your warm up. Secondly, flexible muscles are extremely important in the prevention of most ankle and lower leg injuries. When muscles and tendons are flexible and supple, they are able to move and perform without being over stretched. If however, your muscles and tendons are tight and stiff, it is quite easy for those muscles and tendons to be pushed beyond their natural range of motion. To keep your muscles and tendons flexible and supple, it is important to undertake a structured stretching routine.
