Biomechanics in Podiatry
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.
Effective Foot Stretches and Their Benefits

Foot stretches offer a simple yet powerful way to improve flexibility, relieve tension, and prevent injuries. One effective stretch is the toe stretch, where you sit back on your heels, gently pressing your toes into the ground to stretch the top of the foot. Another beneficial stretch is the calf stretch, achieved by placing hands on a wall, stepping one foot back, and pressing the heel into the ground while keeping the back leg straight. Additionally, the plantar fascia stretch targets the sole of the foot, as you sit with one leg crossed over the other, gently pulling your toes back towards the shin. These stretches can alleviate discomfort caused by conditions like plantar fasciitis and Achilles tendonitis, while also enhancing overall foot mobility and function. Incorporating these stretches into your daily routine, especially before and after physical activity. If you are interested in learning more about specific foot stretches and how they can help relieve foot pain, it is suggested that you contact a podiatrist.
Why Stretching Is Important for Your Feet
Stretching the feet is a great way to prevent injuries. If you have any concerns with your feet consult with John McGhan, DPM from Gold Canyon Foot & Ankle. Our doctor will assess your condition and provide you with quality foot and ankle treatment.
Stretching the Feet
Stretching the muscles in the foot is an important part in any physical activity. Feet that are tight can lead to less flexibility and make you more prone to injury. One of the most common forms of foot pain, plantar fasciitis, can be stretched out to help ease the pain. Stretching can not only ease pain from plantar fasciitis but also prevent it as well. However, it is important to see a podiatrist first to determine if stretching is right for you. Podiatrists can also recommend other ways to stretch your feet. Once you know whether stretching is right for you, here are some excellent stretches you can do.
- Using a foam roller or any cylindrical object (a water bottle or soda can will do), roll the object under your foot back and forth. You should also exert pressure on the object. Be sure to do this to both feet for a minute. Do this exercise three times each.
- Similar to the previous exercise, take a ball, such as a tennis ball, and roll it under your foot while seated and exert pressure on it.
- Grab a resistance band or towel and take a seat. If you are using a towel, fold it length wise. Next put either one between the ball of your foot and heel and pull with both hands on each side towards you. Hold this for 15 seconds and then switch feet. Do this three times for each foot.
- Finally hold your big toe while crossing one leg over the other. Pull the toe towards you and hold for 15 seconds. Once again do this three times per foot.
It is best to go easy when first stretching your foot and work your way up. If your foot starts hurting, stop exercising to ice and rest the foot. It is advised that you then see a podiatrist for help.

Stretching Your Feet
Debilitating foot pain is a problem for many people. But just as stretching the torso can help alleviate back pain, stretching the feet can also help mend existing foot problems and prevent future ones.
The feet, as the body’s foundation, carry the body’s entire weight and can get easily strained from overexertion. Persistent sharp pain and cramping in the feet are often common concerns. Foot pain and foot problems can be due to any number of causes, and in many cases pain may be eased without medication or doctor visits. It is always a good idea, however, to first rule out any serious medical issues with a physician.
Stretching can help relax the feet and alleviate pain, but is especially important before heavy aerobic exercise. Stretching before such activities can help you avoid experiencing painful cramps or strained foot muscles. Stretches should be performed slowly and deliberately without forceful pulling. The stretch should be held for several seconds before relaxing.
A great way to stretch out and loosen up the foot muscles while sitting is to cross one leg over the other and pull the toes carefully back without overextending. Start by resting the left ankle on the right knee. With the left hand, gently flex the left foot by pulling back on the toes. Do not pull too hard; just hard enough to feel the stretch in the arch of the foot. Then point the toes of the left foot as far as you can. Rotate the motion of pointing with pulling back on the toes. This should relax and stretch the muscles on the bottom and the top of the foot. Doing this stretch ten to twenty times should bring relief. Repeat the whole process for the other foot by resting the right ankle on the left knee.
A stretch that focuses on the often injured Achilles tendon involves standing and facing a wall with your arms out and hands flat against the wall. Step back with one foot, keeping it flat against the floor. Move the other leg forward and lean toward the wall. You should feel a stretch through the back of your leg and your Achilles tendon, but do not push yourself too much. Stop when you feel a stretching sensation, and hold for 30 seconds. Ten repetitions may be done for each foot.
Stretching the feet is important for athletes or those performing aerobic exercise, but it can also help anyone with foot pain caused by poor footwear, plantar fasciitis, or long hours standing and walking. Individuals who tend to their feet by regularly stretching every day should be able to minimize foot pain and prevent new problems from arising.
Tips for Preventing Running Injuries

Running injuries can affect runners of all levels, from beginners to seasoned athletes. Achilles pain, characterized by discomfort and swelling at the back of the ankle or heel, is a common ailment resulting from the repetitive strain of running. Heel pain, often associated with plantar fasciitis, can feel like a sharp sensation when pressure is applied to the heel or bottom of the foot. To prevent such running injuries, it's important to take proactive measures. First and foremost, wearing the right shoes is essential, but remember, expensive doesn't always mean better. Additionally, warming up properly before a run with brisk walking or gentle jogging for five to 10 minutes can prepare muscles and reduce the risk of injury. Similarly, cooling down post-run with easy-paced jogging or walking helps muscle recovery. Last, avoid the temptation to increase running intensity or distance too rapidly. Build up your running regimen gradually by increasing distance and duration a week at a time. By utilizing these methods, runners can minimize the likelihood of common running injuries. If foot or ankle pain from running persists or worsens, it is suggested that you seek help from a podiatrist.
Exercising your feet regularly with the proper foot wear is a great way to prevent injuries. If you have any concerns about your feet, contact John McGhan, DPM of Gold Canyon Foot & Ankle. Our doctor will treat your foot and ankle needs.
How to Prevent Running Injuries
Many common running injuries are caused by overuse and overtraining. When the back of the kneecap starts wearing out and starts causing pain in your knee, this is commonly referred to as runner’s knee. Runner’s knee is a decrease in strength in your quadriceps and can occur if you’re not wearing properly fitted or supporting shoes. To prevent runner’s knee, focusing on hip strengthening is a good idea, as well as strengthening your quads to keep the kneecaps aligned.
What Are Some Causes of Running Injuries?
- One cause of a common running injury is called iliotibial band syndrome.
- Plantar fasciitis is also another common injury.
- Stress fractures can occur from overtraining, lack of calcium, or even your running style.
Best Ways to Prevent Running Injuries
- Wear footwear that fits properly and suits your running needs.
- Running shoes are the only protective gear that runners have to safeguard them from injury.
- Make a training schedule. Adding strengthening exercises as well as regular stretching can help keep you strong and limber and can lessen the possibility of injuries.
- Stretching keeps muscles limber; this will help you gain better flexibility.

How to Prevent Running Injuries
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.
Treatment of Gangrene

For individuals with diabetes, the development of gangrene poses serious health risks and requires prompt treatment to prevent further complications. Gangrene results from necrosis, or death of body tissue in the lower legs and feet. Treatment for gangrene in diabetic patients involves a multifaceted approach aimed at halting tissue necrosis, controlling infection, and promoting wound healing. Surgical debridement is essential to remove any dead tissue and prevent further spread. Antibiotic therapy is used for managing bacterial infections associated with gangrene, often administered intravenously for severe cases. Restoring blood flow to the affected area through bypass surgery or angioplasty can help prevent tissue necrosis and reduce the need for amputation. Hyperbaric oxygen therapy delivers high-pressure oxygen to promote healing and control infection. Reconstructive surgery with skin grafts may be necessary to restore tissue integrity in extensively damaged areas. In severe cases, amputation may be required to prevent the spread of gangrene and facilitate prosthetic limb fitting. Throughout this treatment journey, podiatrists play a vital role in wound care, offering specialized expertise in diabetic foot care and wound management. If gangrene is a threat, it is suggested that you schedule an immediate appointment with a podiatrist for wound care and a prognosis.
Wound care is an important part in dealing with diabetes. If you have diabetes and a foot wound or would like more information about wound care for diabetics, consult with John McGhan, DPM from Gold Canyon Foot & Ankle. Our doctor will assess your condition and provide you with quality foot and ankle treatment.
What Is Wound Care?
Wound care is the practice of taking proper care of a wound. This can range from the smallest to the largest of wounds. While everyone can benefit from proper wound care, it is much more important for diabetics. Diabetics often suffer from poor blood circulation which causes wounds to heal much slower than they would in a non-diabetic.
What Is the Importance of Wound Care?
While it may not seem apparent with small ulcers on the foot, for diabetics, any size ulcer can become infected. Diabetics often also suffer from neuropathy, or nerve loss. This means they might not even feel when they have an ulcer on their foot. If the wound becomes severely infected, amputation may be necessary. Therefore, it is of the upmost importance to properly care for any and all foot wounds.
How to Care for Wounds
The best way to care for foot wounds is to prevent them. For diabetics, this means daily inspections of the feet for any signs of abnormalities or ulcers. It is also recommended to see a podiatrist several times a year for a foot inspection. If you do have an ulcer, run the wound under water to clear dirt from the wound; then apply antibiotic ointment to the wound and cover with a bandage. Bandages should be changed daily and keeping pressure off the wound is smart. It is advised to see a podiatrist, who can keep an eye on it.

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.
Athlete’s Foot Types and Risk Factors

Athlete's foot, medically termed tinea pedis, is a fungal infection that appears in various forms, each with distinct characteristics and associated risks. Among these, interdigital infection stands out as the most prevalent, affecting the skin between the toes and causing redness, scaling, and persistent itching. Moccasin infection is found on the sole of the foot, often masquerading as eczema due to its dry, cracked appearance. Vesicular infection results in blisters filled with pus that can rupture into open sores, heightening the risk of secondary bacterial infections. Meanwhile, ulcerative infection presents the most discomfort, with painful, oozing sores between the toes, significantly increasing susceptibility to further complications. These variations stem from exposure to dermatophytes, which are fungi thriving in warm, moist environments. Athlete’s foot infections commonly spread in communal spaces such as locker rooms, swimming pools, and shared footwear. Risk factors for contracting athlete's foot include compromised immune function, genetic predisposition, and prolonged periods of wearing tight, non-breathable shoes. If you have a problematic case of athlete’s foot, it is suggested that you schedule an appointment with a podiatrist for advanced treatment options.
Athlete’s Foot
Athlete’s foot is often an uncomfortable condition to experience. Thankfully, podiatrists specialize in treating athlete’s foot and offer the best treatment options. If you have any questions about athlete’s foot, consult with John McGhan, DPM from Gold Canyon Foot & Ankle. Our doctor will assess your condition and provide you with quality treatment.
What Is Athlete’s Foot?
Tinea pedis, more commonly known as athlete’s foot, is a non-serious and common fungal infection of the foot. Athlete’s foot is contagious and can be contracted by touching someone who has it or infected surfaces. The most common places contaminated by it are public showers, locker rooms, and swimming pools. Once contracted, it grows on feet that are left inside moist, dark, and warm shoes and socks.
Prevention
The most effective ways to prevent athlete’s foot include:
- Thoroughly washing and drying feet
- Avoid going barefoot in locker rooms and public showers
- Using shower shoes in public showers
- Wearing socks that allow the feet to breathe
- Changing socks and shoes frequently if you sweat a lot
Symptoms
Athlete’s foot initially occurs as a rash between the toes. However, if left undiagnosed, it can spread to the sides and bottom of the feet, toenails, and if touched by hand, the hands themselves. Symptoms include:
- Redness
- Burning
- Itching
- Scaly and peeling skin
Diagnosis and Treatment
Diagnosis is quick and easy. Skin samples will be taken and either viewed under a microscope or sent to a lab for testing. Sometimes, a podiatrist can diagnose it based on simply looking at it. Once confirmed, treatment options include oral and topical antifungal medications.

Athlete's Foot
Athlete’s foot is an extremely contagious infection caused by a fungus that results in itching, burning, dry, and flaking feet. The fungus that causes athlete’s foot is known as tinea pedis and thrives in moist, dark areas such as shower floors, gyms, socks and shoes, commons areas, public changing areas, bathrooms, dormitory style houses, locker rooms, and public swimming pools. Athlete’s foot is difficult to treat as well because of the highly contagious and recurrent nature of the fungus.
Tinea is the same fungus that causes ringworm, and is spread by direct contact with an infected body part, contaminated clothing, or by touching other objects and body parts that have been exposed to the fungus. Because the feet are an ideal place for tinea to grow and spread, this is the most commonly affected area. It is, however, known to grow in other places. The term athlete’s foot describes tinea that grows strictly on the feet.
The most commonly infected body parts are the hands, groin, and scalp, as well as the feet. Around 70% of the population suffer from tinea infections at some point in their lives, however not all of these cases are athlete’s foot. Just like any other ailment, some people are more likely to get it than others, such as people with a history of tinea infections or other skin infections, both recurring and non-recurring ones. The extent to which a person experiences regrowth and recurrent tinea infections varies from person to person.
Sometimes people will not even know that they are infected with tinea or that they have athlete’s foot because of a lack of symptoms. However, most experience mild to moderate flaking, itching, redness, and burning. However, some of the more severe symptoms include cracking and bleeding skin, intense itching and burning, pain while walking or standing, and even blistering.
Because of the recurring nature of the tinea fungus and the athlete’s foot it causes, the best way to treat this condition is with prevention. You can take some preventative measures such as wearing flip flops or sandals in locker rooms and public showers to reduce contact with the floor. It also helps to keep clean, dry feet while allowing them to breathe. Using powders to keep your feet dry is a good idea, as well as keeping your feet exposed to light and cool air, to prevent the growth of tinea. If you do happen to get athlete’s foot, opt for using topical medicated creams, ointments or sprays. These treatments help eliminate and prevent it from coming back.
