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.

Many people suffer from foot problems because their shoes are poorly fitted. When shopping for a new pair of shoes, fashion usually triumphs over comfortability. A pair of well fitted shoes is essential in preventing foot problems and potential injuries.

Poorly fitted shoes can cause foot issues such as plantar fasciitis, bunions, hammertoes, ingrown toenails, and foot pain. Shoes such as high heels and sandals may cause problems for your feet. These shoes put the foot in an unnatural position for long periods and fail to provide good foot support. It is recommended to not wear either one for an extended period.

When you are trying on shoes, make sure they have enough space for your toes to move around. Shoes shouldn’t be cramped but also shouldn’t have too much room that your foot moves around in them. A snug shoe is a good choice. They should also provide good arch support and cushioning. Athletic shoes tend to offer both good support and cushioning. A degree of flexibility is necessary so they aren’t too stiff or too unsupportive.

If you can wear your shoes for a long period of time without experiencing any discomfort, this is a sign that your shoes fit properly. Do not be too dismayed if the shoe isn’t a perfect fit at first; many shoes take a few days to weeks to properly break in. However don’t expect an uncomfortable shoe to become fitted to your foot.

For those with foot conditions such as flat feet or pronation, orthotics may be helpful or even necessary to prevent foot pain. Orthotics are inserts that are placed in the shoe and provide support and cushioning for the foot. While there are many types of orthotics out there, custom-made orthotics may be necessary depending upon your foot and foot conditions.

Feet change in size over time. It is important to check your foot size over time so that you can make sure you have the perfect fit for your feet. A podiatrist can provide more information on proper shoe fitting and foot orthotics.

Foot and ankle injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.

Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.

Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.   

Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.

It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.

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.

Tendons are fibrous tissues that connect muscles with bone. The Achilles tendon is the largest tendon in the body. It connects the calf muscles at the back of the leg with the heel, and facilitates movements such as jumping, running, and walking. 

Because the Achilles tendon is engaged so frequently and bears a great deal of pressure and stress throughout the day, it can become injured. Achilles tendon injuries cause the tissue to become irritated, inflamed, and swollen. Pain can come on gradually or be immediate, and will vary from mild to severe depending upon the injury. Where the pain occurs will vary as well, from just above the heel up through the back of the leg. There may also be stiffness in the tendon.

Achilles tendon injuries can often be caused by repetitive stress. They may also occur while running, playing tennis, gymnastics, football, basketball, dancing, soccer, baseball or other sports that require speeding up, slowing down, or pivoting quickly. Wearing high heels, falling from an elevation, stepping in a hole, having flat feet, bone spurs, tight leg muscles or tendons, wearing improper athletic shoes, exercising on uneven surfaces, or starting a new type of exercise can also cause Achilles tendon injuries.

The two most common Achilles tendon injuries are tendonitis and ruptures. Tendonitis causes painful inflammation and can occur in different parts of the tendon. Non-insertional Achilles tendonitis occurs when the fibers in middle of the tendon begin to break down, thicken, and swell. This condition typically affects younger, more active adults. Insertional Achilles tendonitis occurs where the tendon inserts into the heel bone. It is common for bone spurs to form with this type of injury. This condition can affect people of any age and level of activity.

Achilles tendon ruptures are a tear in the tendon. These breaks may be partial or complete. There may be an audible popping noise at the moment of injury and the pain will be sudden and severe.

An Achilles tendon injury can be diagnosed by your podiatrist after they examine you, check your range of motion, and possibly perform a calf squeeze test or review an X-ray or MRI. Depending on the type and severity of your injury, your podiatrist may treat your condition with rest/ice/compression/elevation (RICE), nonsteroidal anti-inflammatory medications, heel lifts, and stretching and strengthening exercises. If you have torn your Achilles tendon, treatment may include physical therapy, ultrasound, shockwave therapy, or possibly even surgery.
