Biomechanics and its related study deal with the forces that act against the body and affect things like our movement. In podiatry, biomechanics are studied to determine the movement of the ankle, toes, and the foot, as well as the forces that impact them. Podiatrists who train in this specialty are able to effectively diagnose and treat conditions that affect people’s everyday movement.

Regardless of your lifestyle, age, or any other factors, many people experience foot problems throughout their lives. Twists and turns, improper balance, and added weight are just a few of the things that can add stress to the feet. These issues can also limit our bodies’ mobility that we often take for granted. Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area. This affects the way you move around on a daily basis.

The history of studying biomechanics dates back to ancient Egypt at around 3000 B.C., where evidence of professional foot care has been recorded. Throughout the centuries, advances in technology, science, and an understanding of the human body led to more accurate diagnosis of conditions such as corns for example. In 1974, biomechanics garnered a large audience when Merton Root founded Root Lab to make custom orthotics. He proposed that corrections of certain conditions could be implemented to gain strength and coordination in the area. Due to his research, we still use his basic principle of foot orthotics to this day.

As technology has improved, so have the therapeutic processes that allow us to correct deficiencies in our natural biomechanics. Computers can now provide accurate readings of the forces, movements, and patterns of the foot and lower leg. Critical treatment options can be provided to patients now who suffer from problems that cause their biomechanics to not function naturally. The best results are now possible thanks to 3D modeling and computing technologies that can take readings and also map out what treatment will do to the affected areas.

These advanced corrective methods were able to come to light thanks to an increase in both the technologies surrounding biomechanics and also the knowledge of how they work naturally. For example, shoe orthotics are able to treat walking inabilities by realigning the posture deviations in patients caused by hip or back problems. Understanding foot biomechanics can help improve movement and eliminate pain, stopping further stress to the foot. Speak with your podiatrist if you have any of these problems.

Tendons are fibrous tissues that connect muscles with bone. The Achilles tendon is the largest tendon in the body. It connects the calf muscles at the back of the leg with the heel, and facilitates movements such as jumping, running, and walking. 

Because the Achilles tendon is engaged so frequently and bears a great deal of pressure and stress throughout the day, it can become injured. Achilles tendon injuries cause the tissue to become irritated, inflamed, and swollen. Pain can come on gradually or be immediate, and will vary from mild to severe depending upon the injury. Where the pain occurs will vary as well, from just above the heel up through the back of the leg. There may also be stiffness in the tendon.

Achilles tendon injuries can often be caused by repetitive stress. They may also occur while running, playing tennis, gymnastics, football, basketball, dancing, soccer, baseball or other sports that require speeding up, slowing down, or pivoting quickly. Wearing high heels, falling from an elevation, stepping in a hole, having flat feet, bone spurs, tight leg muscles or tendons, wearing improper athletic shoes, exercising on uneven surfaces, or starting a new type of exercise can also cause Achilles tendon injuries.

The two most common Achilles tendon injuries are tendonitis and ruptures. Tendonitis causes painful inflammation and can occur in different parts of the tendon. Non-insertional Achilles tendonitis occurs when the fibers in middle of the tendon begin to break down, thicken, and swell. This condition typically affects younger, more active adults. Insertional Achilles tendonitis occurs where the tendon inserts into the heel bone. It is common for bone spurs to form with this type of injury. This condition can affect people of any age and level of activity.

Achilles tendon ruptures are a tear in the tendon. These breaks may be partial or complete. There may be an audible popping noise at the moment of injury and the pain will be sudden and severe.

An Achilles tendon injury can be diagnosed by your podiatrist after they examine you, check your range of motion, and possibly perform a calf squeeze test or review an X-ray or MRI. Depending on the type and severity of your injury, your podiatrist may treat your condition with rest/ice/compression/elevation (RICE), nonsteroidal anti-inflammatory medications, heel lifts, and stretching and strengthening exercises. If you have torn your Achilles tendon, treatment may include physical therapy, ultrasound, shockwave therapy, or possibly even surgery.

Ankle foot orthotics are shoe inserts that offer support to control the placement and movement of the ankle, correct deformities, and compensate for weakness. These inserts are used to stabilize the foot and ankle and provide toe clearance during the swing phase of gate.

Athletes often suffer foot problems because their feet are not being supported within the shoe. Ankle and foot orthotics are custom made inserts that alleviate stress on the foot. However custom orthotics should be prescribed by a podiatrist who specializes in customized footwear and orthotics design. These inserts are used by athletes for different reasons. Runners use orthotics to absorb shock at heel contact and to set up the forefoot for push-off. Basketball players wear them to control their forefeet while jumping and running.

The two main types of orthotics are over-the-counter orthotics and custom-made orthotics. To be eligible for custom orthotics, an examination of the foot and ankle will need to be completed. Afterward, both the foot and ankle will need to be casted and fitted for the proper orthotic. When the fitting process is complete, adjustments can be made to make sure everything fits perfectly.

Over the counter orthotics tend to be more popular than custom fit ones. Athletes who have less severe aches and pains in the foot, ankle or lower back area can use the over-the-counter version of orthotics. Unfortunately, over-the-counter orthotics tend to not work in treating severe injuries or ailments. Whenever you suspect you may need an ankle foot orthotic, you should consult with your podiatrist to determine which type of orthotic is right for you.

Sesamoiditis is a condition that affects the joint that is just behind the big toe in the area known as the ball of the foot. It is most common in younger people and people who have just begun an exercise program. Since the sesamoid bones are like a pulley controlling the big toe, they can rub against each other and cause a gradual onset of pain. Pain may also be caused by the inflammation of tendons surrounding the bones. If ignored, sesamoiditis can lead to other, more serious problems such as severe irritation and fractures of the bones.

The cause of sesamoiditis is sudden increase in activity. The ball of your foot acts as a springboard to help you lift off when you are jogging or running. Sudden increase in the use of these bones or the tendon that controls them can cause irritation. The tendon then begins to develop inflammation and the joint begins to swell. People with smaller, bonier feet or those with a high arch are typically more susceptible to this condition.

Sesamoiditis is fairly simple to diagnose since the symptoms have a gradual onset rather than a sudden impact. The symptoms begin with slight irritation around the joint shortly after the increase in activity. The discomfort eventually turns to pain with light swelling and possibly redness. Although redness or bruising are rare, this may be a symptom. After each session of exercising, the aggravated joint becomes more irritated and increases into a very intense throbbing.

Treatment for sesamoiditis can vary depending on the severity of the situation. However, treatment is almost always approached in a noninvasive way. For a case that is just beginning the doctor may recommend a very strict rest period that will limit the activity allowed on the joint. If you must be active, a recommendation for as modified shoe or insole, along with bandaging and immobilizing the big toe will be made to ensure that pressure is not placed on the joint. For severe cases, it is typically recommended that the joint and the big toe be completely immobilized to allow adequate time to heal. Ice and an over the counter anti-inflammatory may can help with the pain and discomfort while you are at rest.

When you return to your regular exercise activities, it is recommended that you use an insole that will allow even distribution of impact to your entire foot, rather than just the balls of your foot. This will prevent further aggravation of the injury.

Extracorporeal Shockwave Therapy (ESWT) is an alternative treatment method that is used for bone and soft tissue disorders in the foot and ankle. EWST is a noninvasive option for pain relief and it was originally created to help dissolve kidney stones. This therapy works by focusing impulses to target the area in pain. This method has been proven to show a reduction in the amount of nerve fibers that transmit painful impulses, which leads to a reduction in pain. Shockwave therapy can also expedite the tissue which would, in turn, increase the amount of new blood vessels that are formed.

Conditions that can be treated with shockwave therapy include Achilles pain and heel pain. People with plantar fasciitis may opt for this therapy and the results are usually great after 18 months. Additionally, this method can also be used to treat fractures that have failed to heal correctly. Anesthesia is not required to perform this treatment. It usually is not painful, but it can be uncomfortable.

The duration of treatment sessions usually lasts 5-15 minutes each. This procedure is safe since there is no risk of infection from wound complications, if you are looking to try shockwave therapy to heal plantar fasciitis, it may take 3-4 sessions to start working. After treatment, patients typically notice a dull pain in the area which was treated. However, this pain rarely lasts more than 24 hours.

Nevertheless, there are pros and cons that come along with Shockwave Therapy. The most obvious pro is that this treatment is noninvasive, meaning surgery will not be required. Another upside is that there have been very little complications that have been found with this procedure. On the other hand, those who opt for surgery are at risk for continued pain, wound problems, and infections. The biggest con for ESWT is that it is very expensive; it typically costs around $1,000 before insurance. Another con is that the effectiveness of the treatment is questionable. Usually, if this treatment is helpful, the difference is small.

If you are curious about Shockwave Therapy, you should talk to your podiatrist to see if this treatment method is right for you. At times, patients will find that there are other treatment options that are more efficient for their individual cases.
