PLANTAR FASCIITIS

Before we delve into the causes and corrections of Plantar Fasciitis, we first must have a general understanding of where it occurs as it pertains to the anatomy of the foot

There are a total of 26 bones in the foot. The toes contain 14 of these bones with three per toe, except the big toe, which only has two bones. These bones are arranged into three different arches which assist the foot in negotiating alterations in terrain. These arches are labeled as the transverse arch, the medial and lateral longitudinal arches.

The arch that we are concerned with is the medial longitudinal arch which runs along the inside of the foot. Along this arch is a wide, thick ligament which runs from the heel to the balls of the feet before ending at the toes. This is the plantar fascia and when it is subjected to above average amount of strain it begins to over-stretch and tear. Now unfortunately when we rest for long periods of time such as sleeping, our body attempts to heal itself and lays down scar tissue. This doesn't pose much of a problem until rising and we find ourselves in pain as this newly formed scar tissue tears. Hence the notion that with Plantar Fasciitis, the first step is the worst.

Of the two main causes of Plantar Fasciitis, an increase in weight is the most common. This can be caused by any number of factors including pregnancy, inactivity or just plain eating too much. With this increase in weight, more pressure is exerted on the bottom of the foot which in turn stretches the medial longitudinal arch and ultimately the plantar fascia itself.

The second method of increasing plantar fascia tension is due to poor foot biomechanics. The proper gait cycle (walking pattern) has the outside of the heel striking the ground first. This is why it is normal for the outside of the heel to wear down first on footwear. As we move forward, the weight should be distributed mainly along the outside of the foot. This should occur until the opposite leg swings forward, upon which the weight distribution should shift toward the inside of the foot (pronation), followed by pushing off with the middle of the big toe.

The main problem that has been found with foot biomechanics is what is called an overpronation syndrome. Overpronation is when walking, we roll over too much on the inside of the foot. Doing so puts excessive strain on the above mentioned medial longitudinal arch and the tearing of the plantar fascia begins.

Treating Plantar Fasciitis can be accomplished by either losing the extra weight if that is the source or also by rolling a golf ball lightly under the foot which helps strip down the scar tissue. Try not to press down too hard or it is possible to bruise the foot in the process. Another recommended treatment is to have your chiropractic professional adjust your foot to help with the symptoms.

Our heels can move in two directions - diagonally forward and diagonally backward. As we walk the heel moves backwards from the weight-bearing pressure and tension from the Achilles tendon. A visit to your chiropractic professional could result in an adjustment which moves your heel forward to relieve plantar fascia tension and help alleviate your symptoms. If this is not effective, a pair of custom-fit insoles may be required to help straighten your walking gait.
