Biomechanics in Podiatry
Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.
Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.
At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.
Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates. They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.
Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.
Morton's Neuroma
A neuroma is a thickening of nerve tissue and can develop throughout the body. In the foot, the most common neuroma is a Morton’s neuroma; this typically forms between the third and fourth toes. The thickening of the nerve is typically caused by compression and irritation of the nerve; this thickening can in turn cause enlargement and, in some cases, nerve damage.
Neuromas can be caused by anything that causes compression or irritation of the nerve. A common cause is wearing shoes with tapered toe boxes or high heels that force the toes into the toe boxes. Physical activities that involve repeated pressure to the foot, such as running or basketball, can also create neuromas. Those with foot deformities, such as bunions, hammertoes, or flatfeet, are more likely to develop the condition.
Symptoms of Morton’s neuroma include tingling, burning, numbness, pain, and the feeling that either something is inside the ball of the foot or that something in one’s shoe or sock is bunched up. Symptoms typically begin gradually and can even go away temporarily by removing one’s shoes or massaging the foot. An increase in the intensity of symptoms correlates with the increasing growth of the neuroma.
Treatment for Morton’s neuroma can vary between patients and the severity of the condition. For mild to moderate cases, padding, icing, orthotics, activity modifications, shoe modifications, medications, and injection therapy may be suggested or prescribed. Patients who have not responded successfully to less invasive treatments may require surgery to properly treat their condition. The severity of your condition will determine the procedure performed and the length of recovery afterwards.
