The Importance of Biomechanics in Podiatry

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.

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.

Neuropathy

Neuropathy is the weakness, numbness, and pain in the hands and feet due to damage to the peripheral nerves. The peripheral nerves are responsible for sending information from the brain and spinal cord to the rest of your body. Causes of Neuropathy include: traumatic injuries, infections, metabolic problems, exposure to toxins, and diabetes.

Diabetes is the most common cause, with more than half of the diabetic population developing some type of neuropathy. There are several types of neuropathy and they vary based on the damage of the nerves. Mononeuropathy is classified as only one nerve being damaged. When multiple nerves are affected, it is referred as polyneuropathy. One of the types of polyneuropathy is distal symmetric polyneuropathy. It is the most common for people with diabetes and starts when the nerves furthest away from the central nervous begin to malfunction. The symptoms begin with pain and numbness in the feet and then they travel up to the legs. A rarer form of polyneuropathy is acute symmetrical peripheral neuropathy, which is a severe type that affects nerves throughout the body and is highly associated with Guillain-Barre syndrome, an autoimmune disorder that attacks the peripheral nervous system and can be fatal. Although there are many types of neuropathy, most of them share the same symptoms such as pain, extreme sensitivity to touch, lack of coordination, muscle weakness, dizziness, and digestive problems. Since neuropathy affects the nerves, those affected should be careful of burns, infection and falling, as depleted sensations disguise such ailments.

The best way to prevent neuropathy is to manage any medical conditions such as diabetes, alcoholism, or rheumatoid arthritis. Creating and managing a healthy lifestyle can also go a long way. Having a healthy diet full of fruits, vegetables, whole grains and lean protein can keep the nerves healthy. These types of food have the nutrients to prevent neuropathy. Regularly exercising can help as well, but it is best to consult with a doctor about the right amount. In addition to diet and exercise, avoiding risk factors will also prevent neuropathy. This includes repetitive motions, cramped positions, exposure to toxic chemicals, smoking and overindulging on alcohol.

Solutions for Cracked Heels

Cracked heels can make life very frustrating and embarrassing when displaying the bare feet. Aside from being unpleasing to the eye, they can also tear stockings and socks and wear out shoes at a faster rate. When severe, cracked heels may cause pain or infection.

Cracked heels are a problem for those who are athletic, those who may walk a lot, and those who have especially dry skin. Those who use medication that dry the skin, those who swim often, wearing certain types of shoes, and those who are diabetic may have trouble with cracked heels. Seniors whose skin produces less oil may also have trouble with cracked feet. There is no one way to develop cracked feet, and there is no cure.

Today, the market consists of numerous products that have a variety of ingredients to promote healing. Some of these are over-the-counter. Others are prescribed by a doctor, especially for those who have chronic dry feet and heels.

Some doctors recommend wearing socks at night for those with rough skin. This helps further healing, and helps creams stay on longer and better absorb into the skin.

One way to alleviate dryness that causes cracked heels is by using moisturizers both day and night. Another way is to make sure the skin is clean and dry at all times. Using a pumice stone to buff away dead skin before putting on moisturizer can also help. Cracked heels will not respond to the cream unless the outer layer of skin is first removed through exfoliation. After exfoliation, lotion or ointment will be absorbed by the skin more easily.

Foods that produce healing and balance can also help the skin from within. Everything that is put into the body can either help it or hurt it. Taking supplements of omega-3 fatty acids and zinc can also be very beneficial.

Nevertheless, not all products are guaranteed to help treat cracked feet. Seeing a professional is best if other treatments options were unsuccessful. A podiatrist should be able to give the best advice to help with this problem.

Flat Feet

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. 

Wound Care

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.

Foot Pain

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.

How to Care for Your Child's Feet

It is never normal for a child to experience pain in his or her feet. Foot pain that lasts more than a few days and limits a child’s ability to walk should be examined by a podiatrist. Many adult foot ailments originate in childhood and may be present at birth. Common foot issues that are experienced by children are pediatric flat foot, Sever’s disease, ingrown toenails, and plantar warts.

A child’s foot grows rapidly during the first year, allowing it to reach almost half of their adult foot size. Consequently, foot specialists consider the first year to be the most crucial point in the foot development process. There are ways you can help ensure that your child’s foot develops properly. One way is to carefully look at your baby’s feet. If you notice any deformities, you should immediately seek professional care. You should also loosely cover your child’s foot, since tight coverings may prevent movement and inhibit normal development. Another tip is to change the baby’s positioning throughout the day. If your baby lies down in one spot for too long, it may put an excess amount of strain on the feet and legs.

It is best that you try not to force a child to start walking. Children will begin to walk when they are both physically and emotionally capable to do so. You should also avoid comparing your child’s walking progress with other children because the age range for independent walking may range. When your child’s feet begin to develop, you may need to change both their shoe and sock size every few months to allow room for their feet to grow.

Kids are sometimes prone to splinters, cuts, and severe injuries because they tend to walk around barefoot. This also makes them more susceptible to developing plantar warts which is a condition caused by a virus that invades the sole of the foot through breaks in the skin. These ailments can be avoided by making sure your child wears shoes in unsanitary environments. You should also wash any minor cuts or scrapes on your child’s feet. It is a myth that exposure to fresh air will heal injuries; fresh air will only expose your child’s cuts to germs.

As a parent, you should ensure that your child’s feet are developing properly and are being properly maintained. Consequently, it is important that you perform routine inspections on his or her feet to detect any injuries or deformities in their early stages. Early detection and treatment will help to ensure that your child does not develop any serious foot conditions.

Falls Prevention

Elderly Americans are very susceptible to falls as they get older. Everyone experiences decreases in flexibility, balance, strength, and the senses as they age. This correlates to some eye-opening statistics. 1 in 4 Americans aged 65 and older fall each year. An elderly American is being treated for a fall in an emergency room every 11 seconds. In light of these striking statistics, one can see the importance of taking steps to prevent falls.

Finding an exercise program for the elderly is an excellent way to reduce the likelihood of falls. Look for an exercise program that improves strength and balance. Elderly people who live a more sedentary lifestyle, with little physical activity, are at an increased risk of falling. Wearing well-fitted footwear that provides good foot support and cushion will help prevent falls from poorly fitted shoes. Talking to a podiatrist about your susceptibility to falls and about inspecting your prescriptions will help to avoid any medication that could make falls more likely. Due to a decline in the senses among the elderly, having your eyes and hearing checked is recommended.

Around half of all falls occur in the household. Removing tripping hazards in the home and making it more accommodating to older persons can significantly reduce falls. Some notable household changes include increasing lighting around the house, installing grab bars in the shower and bathroom, and making sure the floor is clear of clutter. Other smart options include installing a shower chair, using rubber-bottomed rugs, and placing railings on both sides of stairwells.  

Finally, discuss with a doctor and your family about your fear of falling. This will help to increase awareness among the population on the need for fall prevention. A lack of awareness on the matter, and a downplaying of importance are what increase the risks of falling. Following these tips can help to reduce the risk for yourself and your loved ones.

Sports Related Foot And Ankle Injuries

Foot and ankle injuries are common among people who participate in sports. Several factors contribute to this. They include failing to stretch or warm up properly, not wearing the proper type of shoe and not taping or providing other types of support for the ankle or foot. The most common foot and ankle injuries suffered by people involved in sports are plantar fasciitis, ankle sprains and Achilles tendon damage or ruptures. If not treated properly, they can lead to permanent disability.

Treating these injuries is relatively simple if they are identified and addressed early. Many athletes dismiss the initial aches and pains associated with injury as just soreness or tired muscles. Their first response is usually to try to work through it. This can lead to serious problems. Many minor injuries are made far more serious when athletes continue to put strain and pressure on them. That attitude can change a mild strain into a serious strain and a minor tear into a rupture. Athletes should have unusual aches and pains evaluated by a skilled medical professional.

Plantar fasciitis is a painful injury. It is inflammation of the plantar fascia, the thick band of tissue running from the heel to the base of the toes. If left untreated, it can lead to a degenerative disease called plantar fasciosis. There are several effective treatments for this ailment. Doctors often prescribe rest, massages, stretching, night splints, physical therapy, anti-inflammatory medication, corticosteroids or surgery, usually in that order. The most effective treatment for plantar fasciitis is orthotics, which offers foot support. Surgery is occasionally used as a last resort, but it comes with the risk of nerve damage and infection and often does not stop the pain.

The Achilles tendon is the largest tendon in the body. It connects the calf muscles to the heel bone. Running, jumping and walking all impact this tendon. Two common injuries to the Achilles tendon are tendonitis and a rupture of the tendon. Tendonitis is inflammation in the tendon often caused by an increase in the amount of stress placed on it. Non-surgical treatments include rest, ice or anti-inflammatory medication.  A rupture (tear) of the Achilles tendon can be treated by placing the lower leg in a cast for several weeks or with surgery. Many physicians feel surgery is the better option because it lowers the risk of re-ruptures. Both methods require 4 to 6 months of rehabilitation.

Ankle sprains are the most common sports related foot and ankle injury. A sprain occurs when the ligament holding the ankle bones and joint stretches beyond its normal range. It can be treated non-surgically with a combination of rest, ice wrapped around the joint for 30 minutes immediately after injury, compression by a bandage and elevating the ankle above the heart for 48 hours. This combination is referred to as RICE. Severe ankle sprains in which the ligaments are torn may require reconstructive surgery followed by rehabilitation.

What Are Hammertoes?

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.
