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.

Running may seem like a simple to do. However, running is actually a complex movement that puts stress on the ligaments, bones, and joints of the body.  Selecting the correct running shoe is important for increasing performance and avoiding risk of injury.  Running shoes should be selected based on your foot type.  Considerations such as trail versus road shoes are important. Your foot type dictates the degree of cushioning, stability and motion control you require.  The most accurate way to learn your foot type is to visit a local shop that specializes in running shoes.  Professionals can measure your arch type, stride and gait and help you with your shoe needs.

The design of running shoes is created around the idea of pronation.  Pronation is the natural rolling movement of your ankle from the outside to inside when your foot strikes the ground.  If you run properly you strike the ground on the outside of your heel and roll in the direction of your big toe before pushing off once more.  Pronation is beneficial because it assists the lower half of your body in absorbing shock and storing energy.  Those considered neutral runners pronate correctly and do not need running shoes that help correct their form.  Neutral runners can choose from a wide variety of shoes, including barefoot or minimal types.  However, those who have arch problems or who adopt an incorrect form while running may experience too much or too little pronation. They may require running shoes that offer additional support.

Those who overpronate experience an over-abundance of ankle rolling.  Even while standing, those who severely overpronate display ankles that are angled inward.  It is not uncommon for them to have flat feet or curved legs.  The tendency to overpronate may cause many injuries.  Areas that tend to become injured are the knees, ankles, and Achilles tendon.  If you find that you have a tendency to overpronate, you should look at shoes that provide extra stability and motion-control.  Motion-control shoes are straight and firm. Shoes of this type do not curve at the tip.  The restricted flexibility along the middle of the shoe prohibits the foot from rolling too far inward as your foot strikes the ground.

A less common problem is underpronation.  Underpronation, also called supination, is when the feet are unable to roll inward during landing.  Those who underpronate have feet that lack flexibility and high arches.  This prevents any kind of shock absorption, even though it does place less rotational stress on ankles and knees.  This added force can cause fractures, ligament tears, and muscle strains because the legs are trying to compensate for the impact.  Those who underpronate need shoes with more cushioning and flexibility.  If you have a tendency to underpronate, selecting stability or motion-control shoes may cause you more problems by continuing to prevent pronation.

Gout, typically found in diabetic patients, is an unusually painful form of arthritis caused by elevated levels of uric acid in the bloodstream. The condition typically strikes the big joint on the big toe. It has also been known to strike the knees, elbows, fingers, ankles and wrists—generally anywhere that has a functioning, moving joint.

The high level of uric acid in a person’s bloodstream creates the condition known as hyperuricema—the main cause of gout. Genetic predisposition occurs in nine out of ten sufferers. The children of parents who suffer gout will have a two in ten chance of developing the condition as well. 

This form of arthritis, being particularly painful, is the leftover uric acid crystallizing in the blood stream. The crystallized uric acid then travels to the space between joints where they rub, causing friction when the patient moves. Symptoms include: pain, redness, swelling, and inflammation. Additional side effects may include fatigue and fever, although reports of these effects are very rare. Some patients have reported that pain may intensify when the temperature drops, such as when you sleep.

Most cases of gout are easily diagnosed by a podiatrist’s assessment of the various symptoms. Defined tests can also be performed. A blood test to detect elevated levels of uric acid is often used as well as an x-ray to diagnose visible and chronic gout.

Treatment for gout simply means eliminating symptoms. Non-steroid anti-inflammatory drugs or NSAIDs (Colchicine and other corticosteroid drugs, etc.) will quell the redness, the swelling, and the inflammation. However, managing your diet, lifestyle changes, and using preventative drugs are all helpful toward fully combating the most severe cases.

 Those that lead an inactive lifestyle are at a higher risk for gout. Any amount of exercise decreases the probability of repeat encounters with the condition. Reducing your consumption of red meat, sea food, and fructose-sweetened drinks also reduces the likelihood of chronic gout as well.

Ingesting Vitamin C, coffee, and particular dairy products can help with maintaining a healthy lifestyle. There are new drugs out on the market that inhibit the body’s production of uric acid-producing enzymes. However, reducing or eliminating your overall levels of uric acid is the best remedy to ensuring you lead a gout-free life.

Flatfoot is a condition that occurs when the arches on the foot are flattened, which allows the soles of the feet to touch the floor. Flatfoot is a common condition and it is usually painless.

Throughout childhood, most people begin to develop arches in their feet, however, some do not. Those who do not develop arches are left with flatfoot. The pain associated with flat feet is usually at its worse when engaging in activity. Another symptom that may occur with those who have this condition is swelling along the inside of the ankle.

It is also possible to have flexible flatfoot. Flexible flatfoot occurs when the arch is visible while sitting or standing on the tiptoes, but it disappears when standing. People who have flexible flatfoot are often children and most outgrow it without any problems.

There are some risk factors that may make you more likely to develop flatfoot. Those who have diabetes and rheumatoid arthritis have an increased risk of flatfoot development. Other factors include aging and obesity.

Diagnosis for flat feet is usually done by a series of tests by your podiatrist. Your podiatrist will typically try an x-ray, CT scan, ultrasound, or MRI on the feet. Treatment is usually not necessary for flat foot unless it causes pain. However, therapy is often used for those who experience pain in their flat feet. Some other suggested treatment options are arch supports, stretching exercises, and supportive shoes.
