Pronation, also known as eversion is the term used to refer to the manner of movement of the foot when you are walking or running. Pronation, in itself, isn’t entirely a negative word. Naturally, you can walk, run or stand because of even distribution of your weight around your foot. This is also an aspect of pronation. There are three different types of pronation; we shall discuss each of them below so that you can identify each of them.
Types of Pronation
Normal Pronation: This is what we experience naturally when we are walking or running. This type of movement uses more of the toe area to push off and ensure even distribution of the weight among all the toes. But more of the task is done by the big and second toe, while others provide balance. The Posterior Tibialis muscle majorly regulates pronation. When we are walking or running the muscle lengthens instead of contract.
Overpronation: People who overpronate experience downward and inward rolling of their ankle each time they take a step. This rolling action continues when usually the toe should have started pushing off. It is observed that the big and second toe is doing all of the pushing off, and the weight isn’t evenly distributed. This means there won’t be stability; hence, the foot will twist at every step.
The majority of people that experiences overpronation have flat feet, low or too flexible arches. Overpronation can cause strain on the big toe, second toe, and even the posterior tibialis. It can also cause knee problems and shin split.
It is important to note that overpronation is the normal gait movement of some persons, for some other persons, it is caused by poor posture, overuse, or weakness. Try and wear shoes that will help you to control the movement of your foot.
Underpronation: This is also known as supination. The opposite of what happens in overpronation occurs in supination. In supination, the foot doesn’t roll inward correctly during movement. Instead of the weight of the body to be distributed to the big toe, you would observe that the load is being transferred to the outside foot and the smaller toe. The outside foot and the shorter toe can’t bear the shock. Majority of people that experiences supination are persons that have high, inflexible arches that don’t flatten appropriately during movement.
People who are affected by underpronation should always wear neutral shoes.
Improper pronation can cause further problems with your foot and ankle. If you are having problems possibly caused by the way you walk the doctors at Foot and Ankle Center of Northern Colorado can help.
