Podiatric biomechanics is a particular sector of specialty podiatry with licensed practitioners who are trained to diagnose and treat conditions affecting the foot, ankle and lower leg. Biomechanics deals with the forces that act against the body causing an interference with the biological structure and focuses on the movement of the ankle, the foot and the forces that interact with them.

At some time in our lives we will all experience foot problems, regardless of our lifestyle or age, and we all take our mobility for granted until we are in pain. Twists or turns can cause problems and apply stress to the feet, and that pain will spread from the foot structure to the surrounding tissues. The pain will concentrate in the foot and ankle, but may eventually spread up into the knees, hips and back.

The history of biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded. Afterwards, during the first century AD, corns on feet were recorded as specifically growing on feet and toes. In 1974 biomechanics gained a higher profile from the studies of Merton Root, who claimed that by changing or controlling the forces between the ankle and the foot, corrections of conditions could be implemented to gain strength and coordination to the area. His basic principles of thermoplastic foot orthotics are still in use throughout the industry today.

Modern technology improvements are based on past theories and therapeutic processes providing a better understanding of podiatry concepts for biomechanics. Computers provide accurate determinations about the forces, movements and patterns of the foot and lower legs with the most important information captured. Today’s knowledge of detailed measurement of external and internal forces in the foot is critical to the individual’s treatment. Like most health industries, precise determinations assist the practitioner in diagnosing and prescribing the best treatment for health improving results.

Advances in materials and more awareness of biomechanics have developed enhanced corrective methods, offering further options for foot-related injuries. Shoe orthotics options have expanded to treat walking inability, helping to realign the posture deviations caused by hip or back health occurrences. Attention to posture and foot mechanics uses individual insoles to position the foot, aligning the ankle and leg. The corrected positioning comforts the pressure and helps to ease the pain. Understanding foot biomechanics can help improve and eliminate pain, stopping further stress to the foot. However, these results can only happen if one seeks a podiatrist who specializes in biomechanics.

For hundreds of years, women have been wearing various kinds of high-heels for mostly aesthetic reasons. Women who wear high-heels appear to be taller and to have longer and thinner legs, and the wearer’s gait and posture changes. Though high-heels have had an association with femininity and have kept them popular over the years, there are definite health problems caused by wearing them too frequently.

The motion of the ankle joints is limited when heels are worn. The ankle joint is very important to the body when it comes to walking. Because of their location, these joints have a great deal of weight put on them. Thus, it is very important to keep them as healthy as possible. The Achilles tendon is the main tendon in the ankle. Wearing high-heels too often, studies have shown, can cause the calf muscle and Achilles tendon to shorten and stiffen, which can cause problems when shoes without heels are worn.

By putting a great deal of pressure on the ball of the foot, by forcing the toes into a small toe box, high-heels can cause or may worsen many foot problems, such as corns, hammertoe, bunions, Morton’s neuroma and plantar fasciitis.

Not only does wearing very high-heels regularly have negative effects on the feet, the rest of the body can suffer as well. The knees, one of the most important joints in the entire body, can be affected by wearing high-heels.  High-heels causes the knees to stay bent all the time. Also, it can cause them to bend slightly inward as well. Doctors believe that women can suffer from osteoarthritis later in life because of constantly walking like this. By limiting the natural motion of the foot during walking, high-heels also cause an increased in stress on the knees.

Similarly, the back may also be affected by high-heels because it causes the back to go out of alignment. If high-heels are worn constantly, the spine’s ability to absorb shock can cause continued back pain. They can compress the vertebrae of the lower back, and can overuse the back muscles.

However, this is not to say that high-heels can never be worn. If worn occasionally, they will not cause serious problems. They should not be worn every day in order to avoid the long-term physical health problems of the feet, knees, ankles, and back like mentioned above.

Orthotics is a medical field concerned with the design, manufacture and use of aids used to support weak limbs or direct the proper function of limbs, in this case the foot and ankle. Ankle-foot orthotics, or AFOs, are braces worn at the ankle that encompass some or all of the foot. Diseases that affect the musculature or weaken the affected area require AFOs to strengthen the muscles or train in the proper direction. Tight muscles that need to be lengthened and loosened also benefit from AFOs.

When we think of diseases that affect the musculature we think of the big boys: muscular dystrophy, cerebral palsy, polio and multiple sclerosis. We rarely think that arthritis and stroke can affect the musculature or that there are some who "toe in". But whatever trauma affects that musculature, there is a way to correct it. The orthosis helps to control range of motion, provide support by stabilizing walk, correct deformities and manage pain load. A podiatrist would be consulted for those who "toe in", for instance, or an arthritis sufferer whose ankles suffer through walking on the job or perhaps a victim of stroke whose musculature is wasting away and requires strength.

Before the advent of modern orthotic devices, it wasn’t uncommon to see polio victims wearing metal braces from mid thigh to the bottom of the foot, or children who "toed in" wearing metal braces around their ankle and foot. However, both designs and materials have improved dramatically, allowing for new levels of comfort, functionality, and appearance. Many orthotics are now made from plastics in the shape of an L and designed to fit inside a corrective shoe. These can be rigid, buckling at the calf and extending the length of the foot to support the ankle. This same design except with a hinged ankle provides support while walking by normalizing the gait. In the past boots lined with leather and fiberboard provided the rigidity needed for correction and support. Now corrective shoes are available with built up soles to correct the gait or manage pain by sharing it with another area when the foot spreads during walking.

The podiatrist would prescribe this orthosis in the rigid L shape because the foot moves on a hinge. If the hinge isn't functioning as intended due to an injury or malformation, the muscles tighten up, thus making it difficult to flex the foot. When we walk, the foot flexes and muscles stretch. This brace or AFO would support the ankle and musculature during flexion of the foot, in much the same way a knee brace works. Corrective shoes are for people whose feet hit the ground backward, causing tight muscles and arch problems. Wedges and rocker bars on the heels correct the step to heel first and rock onto the ball of the foot, resulting in relaxed musculature and strengthened ankles.

Appearance also counts when we consider a particular support device, especially if the item is intended for regular, daily wear. The L shaped orthotic is contoured to the calf and flesh-colored, fitting into a sneaker or dress shoe. As present, corrective shoes are more attractive than past models, enabling patients wear such devices with greater comfort and confidence.

Sever's disease, also known as calcaneal apophysitis, is a medical condition that causes heel pain in one or both feet of children during the period when their feet are growing. Sever's disease occurs most commonly in boys and girls between the ages of 8 and 14 years of age.

Sever's disease occurs when the part of the child's heel known as the growth plate, or the calcaneal epiphysis, an area attached to the Achilles tendon, suffers an injury or when the muscles and tendons of the growing foot do not keep pace with bone growth. The result is constant pain experienced at the back of the heel and the inability to put any weight on the heel, forcing the child to bear weight on their toes while walking. A toe gait develops in which the child must change the way they walk to avoid placing weight on the painful heel, a position that can lead to other developmental problems.

The most common symptom of Sever's disease is acute pain felt in the heel when a child engages in physical activity such as walking, jumping or running. Children who are very active athletes are among the group most susceptible to experiencing Sever's disease because of the extreme stress and tension they place on their growing feet. Improper pronation, the rolling movement of the foot during walking or running, and obesity are all additional conditions linked to causing Sever's disease.

The first step in treating Sever's disease is to rest the foot and leg and avoid sports activity which only worsens the problem. Over the counter pain medications targeted at relieving inflammation can be helpful for reducing the amount of heel pain. Combined with rest and pain medication, a child with Sever's disease should wear shoes that properly support the heel and the arch of the foot. Consider purchasing orthotic shoe inserts which can help support the heel and foot while it is healing. Most patients with Sever's disease symptoms report an eventual elimination of heel pain after wearing orthotic insoles that support the affected heel.

Sever's disease may affect just one heel of either foot as well as the heels of both feet. It is important to have a child experiencing heel pain get an examination by a foot doctor who can apply the squeeze test, which compresses both sides of the heel in order to determine if there is intense pain. Discourage any child diagnosed with Sever's disease from going barefoot as this can intensify the problem. Apply ice packs to the affected painful heel two or three times a day for pain relief.

Exercises that help to stretch the calf muscles and hamstrings are effective at treating Sever's disease. An exercise known as foot curling, in which the foot is pointed away from the body, then curled toward the body in order to help stretch the muscles, has also proven to be very effective at treating Sever's disease. The curling exercise should be done in sets of 10 or 20 repetitions, and repeated several times throughout the day.

Treatment methods should usually continue for at least 2 weeks and as long as 2 months before the heel pain goes completely away and the child can resume normal physical and athletic activities again. A child can continue doing daily stretching exercises for the legs and feet to prevent the heel pain of Sever's disease from returning.

Overworking your feet can put stress on your entire body, so taking care of your feet is an absolute priority for overall good health. Standing all day can cause a myriad of different conditions such as bunions, callouses, and plantar warts. These conditions are all very painful but can be avoided with proper foot care, which includes both proper posture and good shoe choices to contribute to the overall health of your feet.

A good place to start is choosing a show that has a negative heel which places the heel slightly lower than the ball of the foot, as shoes designed this way are best for your foot health. Having a job that keeps you on your feet all day makes it an especially a good idea to spend the extra money on a good pair of shoes. And most definitely purchase your shoes from a reputable manufacturer who puts foot health at the forefront of their goals. Having a job that keeps you on your feet all day makes it an especially a good idea to spend the extra money on a good pair of shoes.

The feet were not designed to be enclosed for hours on end. In fact, incorporating some "barefoot" time into your daily routine is not a bad idea to improve overall foot health. There are some other simple things that you can do to help alleviate pain and pressure on the feet from standing all day.

One of the first things you can do is perform some simple foot exercises and some common yoga moves to improve the function of your feet. Foot work outs that aid in your movement will stimulate blood flow and muscles of your feet. Yoga exercises that stretch your feet out flat on the floor can be very beneficial for you if you work on your feet all day. It can also help stretch and relax the calf muscles and Achilles tendon, both of which can become problem areas if not taken care of. You can perform these exercises every day during your daily routine, at the office, at the gym, or even before you go to bed simply stretching your feet out can do wonders for your foot health.

Foot pain that occurs every day because you work for long hours on your feet may lead you to think that this pain is inevitable. However, it does not have to be. Foot stretches and proper footwear work well in alleviating foot pain and preventing further foot problems.

With a little effort and some education, you can keep your feet healthy and feeling good. If your feet hurt, your whole body will eventually feel the effects over time. Start taking care of your feet today!
