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 ankle sprain occurs when one or more ankle ligament gets overly stretched. Ligaments are strong bands of tissue that bind and support the bones and other structures that make up the ankle. In more severe ankle sprains, the ligament(s) tear—either partially or completely—and there may be an audible popping noise at the moment of injury.

Ankle sprains are quite common and can occur when the ankle rolls outwardly (eversion) or inwardly (inversion), causing the ligament(s) to stretch beyond normal limits, or even tear. Falls, twists, or blows to the ankle during sports or other activities can cause this injury, as well as wearing improper footwear, running on uneven surfaces, or having weak ankles.

Depending on the injury’s severity, an ankle sprain will be classified as Grade I, Grade II, or Grade III. Grade I sprains involve ligament(s) being overly stretched but not torn, with symptoms of mild pain, swelling, and ankle instability. There may also be some difficulty bearing weight. A Grade II sprain usually involves a partial tear of the ligament which brings more intensity in these symptoms, along with possible bruising. With a Grade III sprain, the ligament is completely torn, the symptoms are severe, and it may not be possible to put weight on the affected foot at all. 

To diagnose and grade an ankle sprain, a podiatrist will perform a physical examination, checking for tenderness and range of motion in the ankle. For more severe sprains, X-rays or other imaging studies may be necessary. 

It is vitally important to have an ankle sprain treated properly as improper healing often leads to future ankle sprains and possibly even chronic ankle stability. Treatment for an ankle sprain will vary, depending on its severity, and may include the RICE method (Rest/Ice/Compression/Elevation), physical therapy, bracing, medications, and possibly even surgery to repair a torn ligament. Rehabilitation is very important for the sprain to heal properly and to restore functionality.

Many pregnant women complain about foot pain while they are expecting. Foot pain can primarily be caused by weight gain and hormonal changes taking place in the body. By understanding how pregnancy impacts the health of a woman's feet, a pregnant woman can take action to keep her feet as healthy and comfortable as possible.

Because a woman's weight changes during pregnancy, more pressure is brought to bear on both the legs and the feet. This weight shift can cause two major foot problems: over-pronation, also known as flat feet, as well as edema, which is swelling of the feet. Over-pronation occurs when the arch of the foot flattens, causing the foot to roll inwards when the individual is walking, and can aggravate the plantar fascia tissues located along the bottom of the feet. If these tissues become inflamed, a pregnant woman can experience pain in the heel of the foot as well as severe foot pain while walking or standing. Swelling of the feet, or edema, often occurs in the later stages of pregnancy. It is caused by slow circulation and water retention, and may turn the feet a light purple color.

To keep feet in good health and prevent over-pronation, pregnant women should avoid walking barefoot and be sure they are wearing shoes that offer good arch support. A device known as an orthotic can be added to regular footwear in order to provide additional support for the feet during pregnancy. Any expectant mother whose feet hurt should first check to see if the shoes she is wearing are old, worn out and not offering the proper support necessary for distributing the weight of her body during pregnancy.

To treat edema of the feet, a good start is to wear quality footwear which offers support and good circulation. Keep feet elevated whenever possible by using a foot stool while seated. Stay well hydrated by drinking plenty of water to prevent water retention in the feet. Any swelling that occurs in only one foot should be examined as soon as possible by a doctor.

Good foot health during pregnancy can help expectant mothers avoid foot pain that leads to other health problems. Massaging the feet and doing regular gentle exercise like walking aids foot health by contributing to good circulation. Supportive shoes are also a good investment that will support foot health during pregnancy.

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.

Rheumatoid Arthritis is a chronic progressive disease that attacks several joints throughout the body. It is an autoimmune disease in which the body’s immune system mistakenly attacks the joints. As a result, the tissue inside the joints, called synovium, starts to thicken and causes pain around the joints. The synovium is responsible for creating a fluid that lubricates the joints to help them move. Approximately 1.5 million people in the United States have Rheumatoid Arthritis. Women are almost three times as likely to have RA compared to men, and it’s disease usually begins between the ages of 30 and 60. People who have a genetic history of RA are more likely to develop the disease.

Symptoms of RA may include the following sensations in the joints: pain, tenderness, swelling, redness, warmth, stiffness, and loss of range. Swollen joints are a very common symptom for those with the disease. At times, it may be minimal, but it may also be very apparent. Another typical symptom is joint stiffness. Doctors will often use the direction of morning stiffness to measure the severity of a patient’s joint inflammation. Other RA symptoms include limping, anemia, fever, and fatigue.

To diagnose RA, your podiatrist will typically request x-rays to see how much damage there is in the joints. Blood tests may also be performed to show if there are any signs of anemia, or antibodies such as the rheumatoid factor. If you have previously been diagnosed with RA, you should know the disease may spread to your feet and ankles.

There are many non-surgical options that can be used to treat this ailment. Some of these options include physical therapy, foot massages, orthotics, bracing, supportive shoes, and steroid injections. Physical therapy is useful because it will help stretch and strengthen the joints in both the foot and ankle to improve joint function. Massages can help improve blood circulation which will be good for the feet. Choosing proper footwear will allow you to walk with comfortability if you are a sufferer from RA. Lastly, bracing will help stabilize the foot joints, limit deformities and decrease pain.

In severe cases, surgery may be a treatment option that should be considered. For those who cannot walk without experiencing pain and those whose deformities can not be managed with braces, surgery should be considered. Your podiatrist will recommend surgery if he or she believes it will improve your foot biomechanics.
