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.

Diabetic Foot Conditions

According to the American Diabetes Association (ADA), diabetes is a condition that affects approximately 23.6 million Americans.  Around 750,000 new cases are diagnosed each year, and the disease’s most common form, Type 2 diabetes, makes up for 90 to 95 percent of these cases.  Type 2 diabetes is especially prevalent among older Americans, those who are obese, and those who lead sedentary lifestyles.

Complications of the disease may lead to several foot and ankle-related conditions.  The loss of nerve sensation, or neuropathy, can cause diabetics to lose feeling at the bottom of the feet and therefore leave them unaware of pain, pressure, and heat.  Decreased circulation is another complication of diabetes that can slow down the healing of wounds and injuries; this can lead to the development of foot ulcers.

To prevent foot ulcers from forming, diabetics should examine their feet every day for small cuts and wear shoes that curtail pressure.  Constant monitoring for the risk factors associated with ulcer formation can allow for early detection and therefore lessen the possibility of ulcers or, even worse, amputation.  The removal of calluses and ingrown toenails should be left to the podiatrist to avoid improper removal and possible infection.

Diabetic patients may also experience foot deformities due to complications in their feet, such as limited joint mobility, muscle atrophy, and decreased fat padding.  These complications can increase pressure in certain areas of the foot, which in turn can cause certain deformities, such as hammertoe, to form.  Another deformity, Charcot foot, develops due to the collapsing of microfractures in the bones of the feet.  The resulting deformity is a foot that is flattened and wider in appearance.

To help minimize pressure and prevent the development of these diabetes-related foot and ankle conditions, your podiatrist may consider using orthotics or special shoes.  Charcot foot may be treated using walkers, custom orthotic insoles, or non-weight-bearing or rigid weight-bearing casts or braces.  In more serious cases, surgery may be considered to treat more developed deformities.  Ulcers can be further cared for with the help of proper diet, medication to control glucose, intensive wound care, and infection treatment.

How Obesity Affects Your Feet

Gaining weight can happen suddenly and at any time. Usually you won’t notice the extra weight until your feet start hurting at the end of the day. This happens as your feet begin adjusting to carrying more weight. Foot swelling and pain are two of the biggest side effects of having gained weight.

Many foot-related problems can occur even after just putting on a few pounds. This includes the body ‘compensating’ by changing the way it moves. You may find yourself putting extra weight on the wrong parts of your feet and even leaning forward a bit. Your feet were designed to carry a healthy, normal body weight. Extra weight places undue stress on them.

Being overweight often causes the development of Type-2 diabetes, causing leg and foot pain. Older people who do not attempt to control their condition can even lose sensation and feeling in their legs and feet. This can lead to the development of small sores that can lead to serious infection.

Extra stress placed on the joints, tendons and muscles in the feet as a result of extra body weight may also cause heel spurs, or plantar fasciitis. Plantar fasciitis is an inflammation of the foot tissue, causing stiffness and pain when walking and climbing stairs. This can usually be relieved by foot stretches and custom made orthotic shoe-inserts.

Problems in the feet triggered by obesity can be treated by paying special attention to footwear. Proper support shoes that allow for good circulation, especially in the arch and ankle, are vital. A podiatrist can help you find what sort of shoe is most suitable for your feet. They can also measure you for special orthotics if necessary.

It could also be high time to start losing weight in order to treat and prevent diabetes as well as other life threatening diseases. Some methods include yoga and water aerobics, which benefit your entire body without placing stress on your feet. Don’t risk losing your feet by losing interest in them. Take care of your feet and your body, as they deserve the very best.

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.

Plantar Fasciitis

Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia is the thick band of tissue that connects the heel bone to the toes. When this band of connective tissue becomes inflamed, plantar fasciitis occurs. Fortunately, this condition is treatable.

There are several factors that may put you at a greater risk for developing plantar fasciitis. One of the biggest factors is age; plantar fasciitis is common in those between the ages of 40 to 60. People who have jobs that require them to be on their feet are also likely to develop plantar fasciitis. This includes factory workers, teachers, and others who spend a large portion of their day walking around on hard surfaces. Another risk factor is obesity because excess weight can result in extra stress being placed on the plantar fascia.

People with plantar fasciitis often experience a stabbing pain in the heel area. This pain is usually at its worst in the morning, but can also be triggered by periods of standing or sitting. Plantar fasciitis may make it hard to run and walk. It may also make the foot feel stiff and sensitive, which consequently makes walking barefoot difficult.

Treatment for plantar fasciitis depends on the severity of the specific case of the condition. Ice massage applications may be used to reduce pain and inflammation. Physical therapy is often used to treat plantar fasciitis, and this may include stretching exercises. Another treatment option is anti-inflammatory medication, such as ibuprofen.

If you suspect that you have plantar fasciitis, meet with your podiatrist immediately. If left untreated, symptoms may lead to tearing and overstretching of the plantar fascia. The solution is early detection and treatment. Be sure to speak with your podiatrist if you are experiencing heel pain.

Blisters

Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.

The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.

The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.

If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.

Foot Orthotics

Orthotics are shoe inserts that are meant to correct an irregular walking gait or provide cushioning to the feet.  Orthotics come in a variety of different models and sizes, including over-the-counter and customizable variants. Customizable orthotics can be shaped and contoured to fit inside a specific shoe and are typically prescribed through a podiatrist who specializes in customized footwear and orthotics design and management.

Orthotics are beneficial because they can help prevent injuries from occurring and provide cushioning to keep pain levels down to a minimum. They also allow for the correct positioning of the feet. Orthotics can act as shock absorbers to help remove pressure from the foot and ankle. Therefore, orthotics can make bodily movements, such as walking and running, become more comfortable as well as help prevent the development of certain foot conditions.

Orthotics alleviate pain and make the foot more comfortable by slightly altering the angle at which the foot strikes the ground surface, therefore controlling the movement of the foot and ankle. Orthotics come in different variants and can be made of various materials. To determine what type of orthotic is most suited to your feet and your needs, it is best to consult your podiatrist. He or she will be able to recommend a type of orthotic that can help improve your foot function or prescribe a custom orthotic to best fit your feet.  

What is Morton's Neuroma?

Morton’s neuroma, (also referred to as Morton’s metatarsalgia, Morton’s neuralgia, plantar neuroma or intermetatarsal neuroma) is a condition that is caused when the tissue around one of the nerves between your toes begins to thicken. This thickening can result in pain in the ball of the foot. Fortunately, the condition itself is not cancerous.

Morton’s neuroma affects women more often than men with a ratio of 4:1. It tends to target women between the age of 50 and 60, but it can occur in people of all ages. There are some risk factors that may put you at a slightly higher risk of developing the condition. People who often wear narrow or high-heeled shoes are often found to be linked to Morton’s neuroma. Additionally, activities such as running or jogging can put an enormous amount of pressure on the ligament and cause the nerve to thicken.

There usually aren’t any outward symptoms of this condition. A person who has Morton’s neuroma may feel as if they are standing on a pebble in their shoe. They may also feel a tingling or numbness in the toes as well as a burning pain in the ball of their foot that may radiate to their toes.

In order to properly diagnose you, the doctor will press on your foot to feel for a mass or tender spot. He may also do a series of tests such as x-rays, an ultrasound, or an MRI. X-rays are usually done to rule out any other causes for your foot pain such as a stress fracture. Ultrasounds are used to reveal soft tissue abnormalities that may exist, such as neuromas. Your podiatrist may want to use an MRI in order to visualize your soft tissues.

There are three main options for treatment of Morton’s neuroma: Injections, decompression surgery, and removal of the nerve. Injections of steroids into the painful area have been proven to help those with Morton’s neuroma. Decompression surgery has been shown to relieve pressure on the affected nerve by cutting nearby structures such as the ligaments in the foot. Another treatment option would be to surgically remove the growth to provide pain relief.

If you suspect that you have Morton’s neuroma you should make an appointment with your podiatrist right away. You shouldn’t ignore any foot pain that lasts longer than a few days, especially if the pain does not improve.

How to Care for Your Arthritic Foot

Arthritis is an inflammation of the joints and it can occur at any joint in the body, especially in the foot. It generally effects those who are older, however, it can occur at any age. Although there are many different forms of arthritis, there are three main types that occur in the foot. The three types are osteoarthritis, rheumatoid arthritis, and gout.

The primary cause of osteoarthritis is aging. As you age, cartilage degenerates around the joints which causes friction and pain. Obesity can cause osteoarthritis through mechanical stress. Injuries that damage joints can increase the probability as well. Finally, a family history of osteoarthritis can also increase chances of having it.

Rheumatoid arthritis occurs when the immune system attacks the joint linings and weakens them over a long time. While there is no known cause of rheumatoid arthritis, obesity and smoking can increase your chances of getting it. Women are also more likely to get it than men.

Gout is a form of arthritis that occurs when there is too much uric acid in your blood and painful crystals form in your joints. Men are more likely to have gout than women. People who are obese or drink alcohol often are also more likely to develop gout. Furthermore, having diabetes, heart disease, high blood pressure, high cholesterol, gastric bypass surgery or a family history of gout may increase your likelihood of developing the condition.

Symptoms of arthritis include pain, stiffness, swelling in the joints. These symptoms can make it harder and more painful to walk. Physical activity can increase pain and discomfort. Furthermore, joint pain can worsen throughout the day for osteoarthritis. Gout attacks generally last several days with the first few being the worst.

Diagnosis of gout includes either a joint fluid test or a blood test. X-ray imaging can detect osteoarthritis but not gout. On the other hand, there is no blood test for osteoarthritis. Rheumatoid arthritis is difficult to diagnosis. Doctors utilize family and personal medical history, a physical examination, and antibody blood tests to determine if you have rheumatoid arthritis.

Treatment varies for the different kinds of arthritis. Anti-inflammatory medication or steroids can help reduce pain from inflammation of the joints. Changing shoe types can help with some symptoms. Wider shoes can help with discomfort from gout and osteoarthritis. High heels should be avoided. Shoes with proper arch support and that take pressure off the ball of the foot can help with rheumatoid arthritis. Drinking lots of water can also help rid uric acid from the blood. Losing weight, improving your diet, and limiting alcohol and smoking can also help prevent or lessen the symptoms of arthritis.

If you are having trouble walking or pain in your feet, see a podiatrist to check if you have arthritis.

Toenail Fungus

Toenail fungus is a frustrating problem that affects many people. It can be persistent and hard to get rid of. As many different types of fungi are present throughout the environment, it is very easy to contract toenail fungus.  

The feet are especially susceptible to toenail fungus because shoes and socks create the ideal dark and moist environment that fungal infections thrive in. While fungal infections of the nail plate are quite common, if left untreated they can spread beyond the toenail and into the skin and other parts of the body.

Signs of toenail fungus include a thickened nail that has become yellow or brown in color, a foul smell, and debris beneath the nail. The toe may become painful due to the pressure of a thicker nail or the buildup of debris.

Treatment for toenail fungus is most effective during the early stages of an infection. If there is an accumulation of debris beneath the nail plate, an ingrown nail or a more serious infection can occur. While each treatment varies between patients, your podiatrist may prescribe you oral medications, topical liquids and creams, or laser therapy. To determine the best treatment process for you, be sure to visit your podiatrist at the first signs of toenail fungus.
