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.
An ingrown toenail is a nail that has curved downward and grows into the skin. This typically occurs at the nail borders, or the sides of the nail. As a result, pain, redness, swelling, and warmth may occur in the toe. If a break in the skin forms due to the ingrown nail, bacteria may enter and cause an infection in the area; this is typically characterized by a foul odor and drainage.
Ingrown toenails have multiple reasons for developing. In many instances, the condition is a result of genetics and is inherited. The most common cause, however, is improper trimming; cutting the toenails too short forces the skin beside the nail to fold over. An ingrown toenail can also develop due to trauma, such as stubbing the toe, having an object fall on the toe, or participating in activities that involve repeated kicking or running. Wearing shoes that are too tight or too short can also cause ingrown toenails.
Treatment for an ingrown toenail varies between patients and the severity of the condition. Milder cases that don’t involve infection or other medical conditions can benefit from soaking the feet in room-temperature water and gently massaging the side of the nail. In most cases, however, it is best to see your podiatrist for thorough and proper treatment. After examining your toe, your podiatrist may prescribe oral antibiotics to clear the infection if one is present. Surgical removal of either a portion of the nail or the entire nail may also be considered. In some cases, complete removal or destruction of the nail root may be required. Most patients who undergo nail surgery experience minimal pain afterward and can return to normal activity the following day.
Ingrown toenails can be prevented with proper nail trimming and by avoiding improper-fitting shoes. When cutting the toenails, be sure that you are cutting in a straight line and avoid cutting them too short. Shoes should not be too short or tight in the toe box.
Athlete’s foot is a type of fungal infection that affects the skin on the feet. It is caused when the tinea fungus grows on the foot. It is possible to catch the fungus through direct contact with someone who has it or by touching a surface that is contaminated with it. This type of fungus thrives in warm, moist environments such as showers, locker room floors, and swimming pools. Your risk of getting it may also increase by wearing tight-fitting, closed-toe shoes, or by having sweaty feet.
Symptoms of athlete’s foot include itching, stinging or burning sensations between the toes. You may also experience toenails that are discolored, thick, crumbly, or toenails that pull away from the nail bed.
Your podiatrist may diagnose athlete’s foot by detecting these symptoms or by doing a skin test to see if there is a fungal infection present. The most common exam used to detect Athlete’s foot is a skin lesion potassium hydroxide exam. To use this method, your doctor will scrape off a small area of the infected skin and place it into potassium hydroxide. The potassium hydroxide will destroy the normal cells and leave the fungal cells untouched so that they are visible under a microscope.
There are a variety of treatment options for athlete’s foot. Some medications are miconazole (Desenex), terbinafine (Lamisil AT), clotrimazole (Lotrimin AF), butenafine (Lotrimin Ultra), and tolnaftate (Tinactin). While these options may be able to treat your fungus, it is best that you consult with a podiatrist in order to see which treatment option may work best for you.
In some cases, Athlete’s foot may lead to complications. A severe complication would be a secondary bacterial infection which may cause your foot to become swollen, painful, and hot.
There are ways that you can prevent athlete’s foot. Washing your feet with soap and water each day and drying them thoroughly is an effective way to prevent infections. You also shouldn’t share socks, shoes, or towels with other people. It is crucial that you wear shower sandals in public showers, around swimming pools, and in other public places. Additionally, you should make sure you wear shoes that can breathe and change your socks when your feet become sweaty. If you suspect that you have Athlete’s foot, you should seek help from a podiatrist as soon as possible.
Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.
Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound. To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.
To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.
A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.
Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.
A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.
Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.
For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.
There are many reasons why patients experience swelling of the feet. It is rather common and may be a side effect of pregnancy or from sitting and standing for most of the day. Gravity could also play a role in the development of swollen feet. It is known that the weight of blood volume in our bodies is exerted on the veins in the legs and feet. The veins may not work as efficiently during the aging process, and this could make the blood flow backward causing swollen feet. Relief may be found when obese patients lose weight, and it may help to engage in compression therapy by wearing compression socks, stockings, or athletic sleeves. This method can release pressure on the feet and ankles which may help to reduce existing swelling. There are patients who have controlled their swollen feet by implementing healthy lifestyle changes. These can consist of reducing salt intake, incorporating a gentle exercise regime into the daily routine, and drinking plenty of fresh water. Swollen feet may be a temporary condition that affects people who travel via airplane or automobile, so it is beneficial to walk as frequently as possible even though it can be difficult. Swelling of the feet can also be indicative of other health issues so it is important to pay attention to any type of chest pain, mental confusion, dizziness, or fever. If you consistently have swollen feet, it is strongly suggested that you consult with a podiatrist who can help determine the cause and how to effectively treat it.
The Achilles tendon is the strongest tendon in the human body. Its purpose is to connect the lower leg muscles and calf to the heel of the foot. This tendon is responsible for facilitating all types of movement, like walking and running. This tendon provides an enormous amount of mobility for the body. Any injuries inflicted to this tissue should be immediately brought up with a physician to prevent further damage.
The most common injuries that can trouble the Achilles tendon are tendon ruptures and Achilles tendinitis. Achilles tendinitis is the milder of the two injuries. It can be recognized by the following symptoms: inflammation, dull-to-severe pain, increased blood flow to the tendon, thickening of the tendon, and slower movement time. Tendinitis can be treated via several methods and is often diagnosed by an MRI.
An Achilles tendon rupture is trickier to heal, and is by far the most painful injury. It is caused by the tendon ripping or completely snapping. The results are immediate and absolutely devastating, and will render the patient immobile. If a rupture or tear occurs, operative and non-operative methods are available. Once the treatment begins, depending on the severity of the injury, recovery time for these types of issues can take up to a year.
Simple preventative measures can be taken as a means to avoid both injuries. Prior to any movement, taking a few minutes to stretch out the tendon is a great way to stimulate the tissue. Calf raises, squats, leg curls, leg extensions, leg raises, lunges, and leg presses are all suggested ways to help strengthen the lower legs and promote Achilles tendon health.
Many problems arise among athletes and people who overexert themselves while exercising. Problems can also happen among those who do not warm up properly before beginning an activity. Proper, comfortable shoes that fit correctly can also decrease tendon injuries. Some professionals also suggest that when exercising, you should make sure that the floor you are on is cushioned or has a mat. This will relieve pressure on the heels. A healthy diet will also increase tendon health.
It is very important to seek out a podiatrist if you believe you have an injury in the Achilles region. Further damage could result in severe complications that would make being mobile difficult, if not impossible.
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.
Millions of people are affected by diabetes each year. Diabetes damages blood vessels in all parts of the body, especially the feet. The legs and feet may develop slow blood flow, which causes neuropathy, or nerve damage. Once a diabetic patient develops neuropathy, it is important that the feet are well taken care of. Otherwise, the lower limbs may have to be amputated. This only happens in drastic cases, but it shows how seriously diabetic foot care should be taken.
It is very important to always wash and dry the feet thoroughly, especially in between the toes, if you’re a diabetic. Secondly, examining your feet and toes for redness or sores must be done, even if you do not feel pain. You may also want to examine your feet from the bottom. Try to avoid wearing colored socks to prevent infections that may occur from the dye. Well-fitting socks are also highly recommended.
A diabetic’s physician should always monitor their blood levels to test how well blood sugars are being maintained. In addition to giving advice about everyday eating habits and foot care, a physician may prescribe medicine to help with the diabetic patient’s neuropathy. It is also advised to see a podiatrist if experiencing any feet conditions. Toenails may also need to be taken care of by a podiatrist. This prevents patients from cutting too deeply around their cuticles, which can lead to infection.
A person can take care of their feet at home by following the instructions of their physician. Using creams on one’s feet is also an effective way to heal dryness. Proceed with caution when using tools to remove calluses, as severe diabetics may not be able to feel pain on their feet. If any complications arise do not hesitate to contact a podiatrist.
On a daily basis, diabetic feet must be checked. If you are ever concerned about something, contact your health care professional. You never want to wait until a wound becomes too severe to treat. If left untreated, gangrene may develop. Gangrene is a serious infection that can lead to sepsis or amputation. It is also important for diabetics to be on the lookout for ulcers. Ulcers are sores that develop from tissue loss on the skin. They can be quite painful and require intensive treatment. Early treatment and everyday inspection are imperative to staying healthy.
Hammertoes are painful deformities that frequently form on the second, third, or fourth toe. The condition is often caused by an issue in foot mechanics. This can be caused by the person’s specific gait or the manner in which they walk, or by shoes that do not comfortably fit the deformity. Hammertoes can be formed after wearing shoes that are too narrow or short for the foot or have excessively high heels. Shoes that are not properly sized will force the toes into a bent position for long periods of time. This can cause the muscles to shorten and toes to bend into the deformity of a hammertoe.
Hammertoe can also be caused by complications from rheumatoid arthritis, osteoarthritis, trauma to the foot, heredity, or a cerebral vascular accident. Pain and difficult mobility of the toes, deformities, calluses, and corns are all symptoms of a hammertoe.
Someone who suspects they have the symptoms of a hammertoe should consult with a physician—particularly a podiatrist. Podiatrists diagnose and treat complications of the foot and ankle. If the podiatrist discovers that the affected toes are still flexible, treatment for the hammertoe may simply involve exercise, physical therapy, and better-fitting shoes. Treatment for hammertoes typically involves controlling foot mechanics, such as walking, through the use of customized orthotics.
For more serious cases in which the toes have become inflexible and rigid, surgery may be suggested. During the operation, the toe would receive an incision to relieve pressure on the tendons. A re-alignment of the tendons may then be performed by removing small pieces of bone to straighten the toe. In some cases, the insertion of pins is needed to keep the bones in the proper position as the toe heals. The patient is usually allowed to return home on the same day as the surgery.
If surgery is performed to repair a hammertoe, following the postoperative directions of your doctor is essential. Directions may include several stretches, picking up marbles with your toes, or attempting to crumple a towel placed flat against your feet. Wear shoes that have low heels and a wide amount of toe space to maintain comfort. Closed-toe shoes and high heels should be avoided. Shoes with laces allow the wearer to adjust how fitted he or she may want the shoes to be and also allow for greater comfort. To provide adequate space for your toes, select shoes that have a minimum of one-half inch of space between the tip of your longest toe and the inside of the shoe. This will also relieve pressure on your toes and prevent future hammertoes from forming.
Other preventative measures that can be taken include going shopping for new shoes in the middle of the day. Your feet are its smallest in the morning and swell as the day progresses. Trying on and purchasing new shoes midday will give you the most reliable size. Be sure to check that the shoes you purchase are both the same size. If possible, ask the store to stretch out the shoes at its painful points to allow for optimum comfort.
Athlete’s foot is an extremely contagious infection caused by a fungus that results in itching, burning, dry, and flaking feet. The fungus that causes athlete’s foot is known as tinea pedis and thrives in moist, dark areas such as shower floors, gyms, socks and shoes, commons areas, public changing areas, bathrooms, dormitory style houses, locker rooms, and public swimming pools. Athlete’s foot is difficult to treat as well because of the highly contagious and recurrent nature of the fungus.
Tinea is the same fungus that causes ringworm, and is spread by direct contact with an infected body part, contaminated clothing, or by touching other objects and body parts that have been exposed to the fungus. Because the feet are an ideal place for tinea to grow and spread, this is the most commonly affected area. It is, however, known to grow in other places. The term athlete’s foot describes tinea that grows strictly on the feet.
The most commonly infected body parts are the hands, groin, and scalp, as well as the feet. Around 70% of the population suffer from tinea infections at some point in their lives, however not all of these cases are athlete’s foot. Just like any other ailment, some people are more likely to get it than others, such as people with a history of tinea infections or other skin infections, both recurring and non-recurring ones. The extent to which a person experiences regrowth and recurrent tinea infections varies from person to person.
Sometimes people will not even know that they are infected with tinea or that they have athlete’s foot because of a lack of symptoms. However, most experience mild to moderate flaking, itching, redness, and burning. However, some of the more severe symptoms include cracking and bleeding skin, intense itching and burning, pain while walking or standing, and even blistering.
Because of the recurring nature of the tinea fungus and the athlete’s foot it causes, the best way to treat this condition is with prevention. You can take some preventative measures such as wearing flip flops or sandals in locker rooms and public showers to reduce contact with the floor. It also helps to keep clean, dry feet while allowing them to breathe. Using powders to keep your feet dry is a good idea, as well as keeping your feet exposed to light and cool air, to prevent the growth of tinea. If you do happen to get athlete’s foot, opt for using topical medicated creams, ointments or sprays. These treatments help eliminate and prevent it from coming back.
Our feet are arguably the most important parts of our bodies because they are responsible for getting us from place to place. However, we often don’t think about our feet until they begin to hurt. If you have pain in your feet, you need to first determine where on the foot you are experiencing it to get to the root of the problem. The most common areas to feel pain on the foot are the heel and the ankle.
Heel pain is most commonly attributed to a condition called plantar fasciitis. Plantar fasciitis occurs when the plantar fascia, which is the band of tough tissue connecting the heel bone to the toes becomes inflamed. Plantar fasciitis pain is usually worse in the morning, and it tends to go away throughout the day. If you have plantar fasciitis, you should rest your foot and do heel and foot muscles stretches. Wearing shoes with proper arch support and a cushioned sole has also been proven to be beneficial.
Some common symptoms of foot pain are redness, swelling, and stiffness. Foot pain can be dull or sharp depending on its underlying cause. Toe pain can also occur, and it is usually caused by gout, bunions, hammertoes, ingrown toenails, sprains, fractures, and corns.
If you have severe pain in your feet, you should immediately seek assistance from your podiatrist for treatment. Depending on the cause of your pain, your podiatrist may give you a variety of treatment options.
Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.
Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.
Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.
To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.
Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.
Pain experienced in the ankle can be caused by a multitude of conditions. While the most common cause is an ankle sprain, other possible problems can include arthritis, gout, ankle instability, an ankle fracture, nerve compression, or tendinitis. In more serious cases, ankle pain can be a sign of improper alignment of the foot or an infection.
Ankle pain can often be accompanied by symptoms such as redness, swelling, stiffness, and warmth in the affected area. Pain can be described differently depending on the condition: short, stabbing pain and a dull ache are some examples. If such symptoms are persistent and do not improve after time, be sure to schedule an appointment with your local podiatrist.
Depending on the condition causing your ankle pain, different treatments may be prescribed by your podiatrist. For ankle sprains, the first step in treatment involves rest, ice, elevation, and compression. Be sure to avoid placing pressure on the ankle, use an ice pack several times a day, and use a compression bandage and elevation to reduce swelling. Other, more serious conditions may require the assistance of certain drugs and medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, or even cortisone injections.
Depending on the severity of your ankle pain and the condition behind it, recovery from ankle pain may take some time.
Consult with your foot and ankle doctor to best determine the cause of your ankle pain and the appropriate treatment.
