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.
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.
Blisters are a common ailment of people who wear shoes that are either too tight or rub against the feet in an uncomfortable way. Knowing the basics of blisters is important for understanding how they are formed and what treatments should be used for them.
A blister on the foot, or any other part of the body, is a small pocket that is filled with fluid. It usually forms on the upper layer of the skin because these layers are loose enough to allow a blister to form. The most common fluid in a blister is just a clear, watery-like fluid that usually isn’t cause for concern. However, blisters can fill up with blood if they are deep enough and pus if they have become infected with bacteria.
Blisters almost always form on the feet due to shoes rubbing up against the foot, where the friction causes blisters. These can occur after you have walked for a long period of time or when your shoes do not fit you properly. Your feet are also more prone to blisters if they are moist, so keeping them dry and clean is one preventative step you can take.
Preventing infection should be the number one concern when treating blisters, as well as relieving the pain they can cause. Using a bandage to cover up the blister will help it heal and prevent bacteria from entering it. New skin will form under the blister and eventually cause it to pop. You can also take a sterilized pin and try to pop it yourself.
If the blister is filled with pus or blood, seeking treatment from a doctor is ideal. Antibiotics may need to be taken in order to completely eliminate the bacteria inside the blister. See a doctor to have an antibiotic prescribed.
The best way to treat blisters is to prevent them all together. Keeping your feet dry and making sure that your shoes fit properly are just two of the steps you can take to prevent blisters. Shoes that are too tight or shoes that are too loose and allow your feet to slide in them will cause blisters. Applying a bandage to an area where you think a blister is about to form is another way you can prevent them.
Heel spurs are calcium deposits that cause bone protrusions on the heel bone. Heel spurs are usually associated with plantar fasciitis, which occurs when the plantar fasciitis in the foot becomes inflamed. Typically, heel spurs don’t cause any symptoms. However, they can produce chronic or intermittent heel pain. Those who have had the condition often describe the irritation as a stabbing pain.
There are risk factors that may make you more likely to develop heel spurs. People who have abnormal walking gaits, run and jog on hard surfaces, are obese, or wear poorly fitting shoes are more likely to develop heel spurs.
Fortunately, there are precautions you can take to avoid developing heel spurs. One of the best ways to do this is by wearing well-fitting shoes with shock-absorbent soles. Another preventative technique is to choose running shoes if you plan on running, and walking shoes if you plan on walking. Shoes are made for different activities and it is important to research a shoe before you purchase a pair.
The pain associated with heel spurs often decreases the more you walk. However, a recurrence of pain after an extended period of rest or walking is likely to occur with this condition. Those with severe heel spur pain may opt to go the surgical route for treatment. However, more than 90% of those with the condition get better without surgical treatment. If you have a heel spur and want to know if surgery is right for you, you should go to your podiatrist and he or she will be able to conduct a pre-surgical test or exam to determine if you are an optimal candidate for surgery.
Have you ever gotten up from a chair or out of bed in the morning, and upon taking that first step, feel like your heel has stepped on a tack? Many people experience a feeling of sharp pain which radiates into their arch from their heel and which does not allow them to put their heel on the floor. Sometimes they need to sit back down, stand only on their toes and use the wall for balance. If you can take a few steps, it seems to go away and lessen, allowing you to then resume your activity. Later, throughout your day and after a period of rest, it can happen again. If this sounds familiar you may be suffering from your first attack of heel pain.
Heel pain is a debilitating condition that affects day to day activities. Running and walking both causes stress on the heel because the heel is the part of the foot that hits the ground first. This means that the heel is taking on your entire weight. Diagnosis and treatments for heel pain can be easily found through your podiatrist.
Plantar Fasciitis
One of the main causes of heel pain is a condition known as plantar fasciitis. The plantar fascia is a band of tissue that extends along the bottom of the foot, from the toe to the bottom of the heel. A rip or tear in this ligament can cause inflammation of these tissues, resulting in heel pain. People who do not wear proper fitting shoes are often at risk of developing problems such as plantar fasciitis. Unnecessary stress from ill-fitting shoes, weight change, excessive running, and wearing non-supportive shoes on hard surfaces are all causes of plantar fasciitis.
Achilles Tendonitis
Achilles tendonitis is another cause of heel pain. Similar to plantar fasciitis, inflammation of the Achilles tendon will cause heel pain due to stress fractures and muscle tearing. A lack of flexibility of the ankle and heel is an indicator of Achilles tendonitis. If left untreated, this condition can lead to plantar fasciitis and cause even more pain on your heel.
Heel Spur
A third cause of heel pain is a heel spur. A heel spur occurs when the tissues of the plantar fascia undergo a great deal of stress, leading to a separation of the ligament from the heel bone entirely. This results in a pointed fragment of bone on the ball of the foot, known as a heel spur.
Limb salvage is a procedure that involves saving a lower extremity from amputation. In podiatry, limb amputation often occurs as a result of diabetes. The fundamental goal of limb salvage is to restore and maintain stability and movement of the affected lower extremity.
The procedure typically involves removing the diseased tissue and a small portion of the surrounding healthy tissue, as well as the removal of any affected bone if necessary. If bone is removed it is then replaced with prostheses, or synthetic metal rods or plates, or grafts from either the patient’s body or a donor. Limb salvage is typically the preferred choice of procedure over amputation, as the procedure preserves both the patient’s appearance and allows for the greatest possible degree of function in the affected limb.
Upon diagnosis and determining that limb salvage is the appropriate treatment, the podiatrist may enlist the help of a physical and/or occupational therapist to prepare the patient for surgery by introducing various muscle-strengthening, walking, and range of motion exercises. Such exercises may be continued as rehabilitation post-procedure.
Plantar warts are described as small growths that appear on the heels or other areas of the feet that bear a large amount of weight. The pressure in these areas causes plantar warts to hide behind thick layers of skin called calluses. In most cases, plantar warts are not a serious health issue, and they usually go away without treatment. However, it is still important be mindful of them.
Plantar warts are caused by infections with human papillomavirus (HPV) in the outer layer of skin on the soles of the feet. The plantar warts then develop when the virus enters the body through weak spots at the bottom of the feet, such as tiny cuts and breaks. Plantar warts are not guaranteed for all who encounter the virus. Everyone responds differently to the affects of HPV.
Plantar warts are most common in the following groups: children and teenagers, people with weakened immune systems, people with history of plantar warts, and people who walk barefoot. Exposure to HPV is common in environments such as locker rooms or pool areas.
One of early signs to look out for is a callus, since many plantar warts hide behind them. You can also locate these warts by looking for small, fleshy, rough, grainy growths near the base of the toes and the heel. Early signs of plantar warts are shown by black pinpoints, which are small, clotted blood vessels. Lesions that interrupt normal lines and ridges in the skin of your foot may also be a sign of plantar warts. Any feeling of pain while walking or standing can also be a symptom of plantar warts.
Although most cases are not serious, some conditions may require a visit to your podiatrist. If you are uncertain that your lesion is a wart, if you have diabetes, or if you are experiencing bleeding, you may need to see a seek professional treatment. Your doctor may offer treatments such as prescribing stronger peeling medicine or using cryotherapy by applying liquid nitrogen to the wart. More serious cases may require minor surgery or laser treatment.
There are simple solutions available to help prevent plantar warts. One common task is to avoid walking barefoot in swimming pool areas and locker rooms, as this is where HPV is commonly present. Keeping your feet clean and dry, while changing shoes and socks daily can also help prevent future plantar warts. If you know someone who has plantar warts, it is important to avoid direct contact with their warts. You should also refrain from picking or scratching your wart if you happen to develop one.
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.
A congenital foot problem is a problem affecting the feet, toes, and/or ankle that a child is born with. Several issues with a child’s feet can occur congenitally. Such problems include clubfoot, vertical talus, tarsal coalition, polydactyly, macrodactyly, and cleft foot. Some of these problems have a genetic basis, with someone in their family history having a gene causing the condition, and some are simply an anomaly.
The following are specifics about a few of these conditions:
- Clubfoot, also called congenital talipes equinovarus or talipes equinovarus, is When the tendons of the foot shorten, the bones are of an unusual shape, and the Achilles tendon is tight, causing an inward and downward pointing of the foot. The soles of the feet might also face each other. In most cases of clubfoot, both feet are affected. If not treated, the affected child will walk on the sides of their feet or ankles.
- Polydactyly is a condition where the child has more than five fingers or toes on either or both feet. Presentation usually consists of a nubbin or small lump of tissue without a bone, a toe that is partially formed but has no joints, or an extra toe.
- Vertical talus is where the talus bone forms in the wrong position, other bones in the foot do not line up properly, the front of the foot points up, and the bottom of the foot is stiff, has no arch, and usually curves out. This can occur in one or both feet and if left untreated, can lead to serious disability or discomfort as the child grows.
- Tarsal coalition is when there is an abnormal connection of two or more bones in the foot leading to severe, rigid flatfoot. The tarsal bones, located toward the back of the foot and in the heel, are the ones affected. This condition is often present at birth, but signs of the disorder usually come on in early adolescence.
- Cleft foot is a rare condition where the foot has missing toes, a V-shaped cleft, and other anatomical differences. Surgery can often help improve the foot’s function since the heel remains normal and is what is most needed for walking. The main issues with this affliction are whether the affected foot can fit into a shoe and the shape and appearance of the foot.
- Macrodactyly is when the toes are abnormally large due to overgrowth of the underlying bone or soft tissue. Having this condition makes it harder for the child to use the affected foot for certain activities.
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.

Whether your feet are over-worked or under-worked, chances are they could benefit from some special attention. Even those who exercise regularly probably do not spend any time strengthening their feet. This can be just as rewarding as strengthening the rest of the body, since the health of your feet affects the health of the rest of the body as well, especially the ankles, legs, and spine.
For those who might not have any idea on how a foot-specific exercise might be conducted, there are several workouts that are fairly easy to perform in the comfort of ones’ home. One of the easiest is the toe rise, also known as the tip-toe. This exercise involves standing on the tip-toes for a count of 15 then resting the feet on the ground. This process should be repeated a minimum of three times a day in order to strengthen the feet.
Toe pick-ups strengthen the feet by working them in a very different way. In this exercise, small items are picked up using the toes in order to strengthen the muscles on the upper part of the feet. Once again three sets should be performed, with the item in question being held for 15 seconds then dropped. Items that may be picked up using the feet include marbles and even stationery, which works wonders for the toes and the surrounding muscles.
Yet another simple workout is the ankle pump. This can be done either upwards or downwards, but for the workout to be most effective both can be incorporated into the routine. As the term suggests, this involves lifting the foot off the floor and flexing the toes either towards the shin or towards the ground. This movement puts the feet and ankles through a large range of motion which works the muscles.
Last but not least, feet should be stretched so that the muscles can relax and recuperate. This can be done by placing both feet off of the floor and bracing oneself against the wall at a 45 degree angle. This ensures that the feet and ankles are adequately stretched once the workout is complete.
In short, giving the feet a good workout every now and then is important in order to avoid problems such as plantar fasciitis. It’s also important to warm-up or cool-down after running or vigorous walking. Foot exercises may be followed by a good foot massage. This encourages circulation in the feet as well as muscle relaxation.
Toenail fungus is a frustrating problem that affects many people. It can be persistent and hard to get rid of. As many different types of fungi are present throughout the environment, it is very easy to contract toenail fungus.
The feet are especially susceptible to toenail fungus because shoes and socks create the ideal dark and moist environment that fungal infections thrive in. While fungal infections of the nail plate are quite common, if left untreated they can spread beyond the toenail and into the skin and other parts of the body.
Signs of toenail fungus include a thickened nail that has become yellow or brown in color, a foul smell, and debris beneath the nail. The toe may become painful due to the pressure of a thicker nail or the buildup of debris.
Treatment for toenail fungus is most effective during the early stages of an infection. If there is an accumulation of debris beneath the nail plate, an ingrown nail or a more serious infection can occur. While each treatment varies between patients, your podiatrist may prescribe you oral medications, topical liquids and creams, or laser therapy. To determine the best treatment process for you, be sure to visit your podiatrist at the first signs of toenail fungus.
Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.
The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.
The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.
If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.
Overtraining and overusing the feet are the main causes of common running injuries. A number of these common injuries are caused by overrunning. Runner’s knee is a condition that is characterized by the back of the kneecap beginning to wear away and cause pain in the knee. This frequently occurs due to either a decrease in strength in the quadriceps muscles or ill-fitting shoes that are lacking in proper support for the inside of the forefoot. Strengthening exercises focusing on the quad muscle and sports orthotics are the usual treatments for those suffering from runner’s knee. Prevention of the condition lies in a focus on hip strengthening and quad-strengthening to keep the kneecap aligned. To help learn the best exercise to heal runner’s knee, one can also undergo physical therapy.
One common injury, called iliotibial band syndrome, is often caused by overtraining. This condition occurs when the iliotibial band gets irritated, creating pain and discomfort in the outside knee area. Plantar fasciitis, another common running injury, also occurs as a result of inflammation and irritation. Plantar fasciitis is an inflammation and irritation of the bone in the foot. A large amount of pain is often experienced due to plantar fasciitis. The condition can be caused by a high arch, improper footwear, tight muscles, or flat feet. It can best be avoided by stretching and wearing appropriate footwear that supports the foot.
Another common injury for runners is stress fractures. These injuries occur due to running style, overtraining, or a lack of calcium. Stress fractures most often occur in several locations in runners, including the inner bone of the leg, the thighbone, the bone at the base of the spine and the bones of the toes. Stress fractures are best prevented by wearing proper footwear and by running on flat and hard surfaces; this will absorb some of the shock created during running.
Aside from overtraining, other causes of common running injuries include ill-fitting footwear, a lack of flexibility and strength, and irregular biomechanics. The best way to avoid running injuries is to prevent them from even occurring. Both iliotibial band syndrome and stress fractures are preventable. The first step that should be taken to prevent running injuries is to only wear footwear that fits properly and that is appropriate for whatever activity you are doing. Running shoes are the only protective gear available to runners that can safeguard them from sustaining injuries. Choosing the right pair of shoes is therefore extremely important. While running shoes are an important factor, it is also important to consider other facets of your running routine such as training schedules, flexibility, and strengthening. These elements should be considered and altered according to your running needs to best maximize your run and minimize the possibility of injury. Careful stretching before and after a run should also be considered to help prevent running injuries. Stretching muscles enables greater flexibility and a lesser chance of sustaining injury.
