Biomechanics in Podiatry

 

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.

Heel Pain

Heel pain is a stressful condition that effects day to day activities. Running and walking causes stress on the heel because the heel is the part of the foot that hits the ground first. This means that the heel is taking on your entire weight. Diagnosis and treatments for heel pain can be easily found through your podiatrist.

One of the main causes of heel pain is a condition known as plantar fasciitis. The plantar fascia is a band of tissue that extends along the bottom of the foot, from the toe to the bottom of the heel. A rip or tear in this ligament can cause inflammation of these tissues, resulting in heel pain. People who do not wear proper fitting shoes are often at risk of developing problems such as plantar fasciitis. Unnecessary stress from ill fitting shoes, weight change, excessive running, and wearing non-supportive shoes on hard surfaces are all causes of plantar fasciitis.

Achilles tendonitis is another cause of heel pain. Similar to plantar fasciitis, inflammation of the Achilles tendon will cause heel pain due to stress fractures and muscle tearing. A lack of flexibility of the ankle and heel is an indicator of Achilles tendonitis. If left untreated, this condition can lead to plantar fasciitis and cause even more pain on your heel.

A third cause of heel pain is a heel spur. A heel spur occurs when the tissues of the plantar fascia undergo a great deal of stress, leading to a separation of the ligament from the heel bone entirely. This results in a pointed fragment of bone on the ball of the foot, known as a heel spur.

Treatments for heel pain are easy and effective as long as problems are addressed quickly. The most common solution is simply taking stress off the feet, particularly off of the heel. This will ease the pain and allow the tendons and ligaments to relax. In the case of both plantar fasciitis and Achilles tendonitis, icing will reduce swelling of any part of the foot and anti-inflammatory medication is highly recommended. Properly fitting your shoes and wearing heel pads or comfort insoles will also reduce the risk of developing heel pain. Stretching before and after exercises such as running will help the foot muscles prepare for stress and lower the chances of inflammatory pain. In extreme cases, relieving heel pain might require surgery. Always make sure to discuss these symptoms and treatment options with your podiatrist to keep yourself active and pain free.

Working on Your Feet

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!

Are your shoes the right size? Many people are walking around with ill-fitting shoes. Picking the right shoe size is not rocket science, but there are a few things to remember when selecting your next pair.

Most shoe stores and department stores have rulers for measuring your feet, and these can give you an exact size. Be sure to measure with your shoe on. Measuring your foot will give you a different size than your shoe. If you do measure your foot size, you will need to add 1-2 inches to get the proper sizing.

Wiggle room is the most important factor when selecting shoes. Make sure that your toes are not cramped and that you can wiggle them. A rule of thumb is that there should be one inch between your toes and the tip of your shoe. If your shoes are not properly sized, you can experience foot pain, knee pain, blisters and swelling.

Don’t assume that you will always wear the same size in a shoe. Often manufacturers size shoes differently. The size you wear with one company may not be the same as the size you wear with another. Make sure that the company you buy from has a return policy. No one needs a closet full of shoes which they cannot wear.

It is advisable not to buy your shoes in the morning, but rather late in the day. Your feet actually swell as the day goes on and you need plenty of room to walk comfortably. Buying shoes in the morning that are snug is sure to cause problems once the day is done. Also, make sure that you are buying the right sizes for both feet. It is not uncommon for one foot to be larger than the other, and some people have to buy two separate sizes to accommodate different sized feet.

The biggest concern in buying shoes is comfort. Oftentimes people will buy shoes that are not the most comfortable in the store. People think that the shoes simply need to be “broken in”. If a shoe does not fit in the store, it will not fit at home either. Comfort should be the ultimate goal when purchasing a pair of shoes; your feet will thank you.

Let’s face it; we all walk a lot, some of us more than others. Selecting the best shoes for your particular lifestyle is essential. By properly sizing your shoes and buying the proper comfort level, your feet will be dancing all day long.

Toenail Fungus

Toenail fungus is a frustrating and embarrassing problem for many people. It can be persistent and hard to get rid of. Thankfully, there are a number of options for treatment available.

 

The most effective treatment for toenail fungus is Lamisil. However, any anti-fungal treatment sold to get rid of athlete's foot can also be used. In the ingredients list on products sold to kill fungal growth on the body, look for the ingredient terbinafine. Terbinafine is a chemical product that kills fungal growths. Using a product with terbinafine in it will essentially damage the cell membrane of the fungus organism. However, don't expect immediate results. You will need to apply the medication regularly, and make sure to keep washing the affected area and drying it thoroughly. The fungus needs moisture, air and your skin to live.

 

Taking other precautions can also help with fungus. Use a powder such as talcum powder in the shoes to absorb sweat and moisture. It is also important to wear sandals or loose-fitting, open-toed shoes which will improve air-flow around the feet, keeping the feet dry. These kinds of shoes will also expose your feet to light, which is not favorable to fungus growth. Wearing socks that wick moisture and dry quickly will also help control fungus.

 

Although Lamisil and other medications containing terbinafine have been proven effective, they also cause a number of side effects which may be undesirable. If you decide that this kind of medication is not for you, there are a number of natural remedies to try. Applying alcohol, tea tree oil, hydrogen peroxide, or Vicks VapoRub to the nail regularly may solve the problem.

 

Your podiatrist might also recommend soaking your toenails in a gentle bleach solution. Anecdotal evidence suggests that vinegar and Listerine may also be effective when used as a soaking solution. These are simple treatments, but ones that require patience and consistency. There are also topical products available from your pharmacy which is manufactured especially for toenail fungus.

 

There are more immediate treatments for toenail fungus available using laser surgery. If you are looking for an immediate and quick removal of the toenail fungus, you will need to find a laser surgeon who can cut the growth out of your toenail. Don't try to cut the toenail fungus out using toenail scissors or other kinds of scissors. Once you get rid of your fungus infection, you will need to throw out your old shoes to avoid reinfection.

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 mend existing problems and prevent future ones.

The feet carry the entire weight of the human body all day and can get easily strained from overexertion. Persistent sharp pain and cramping in the feet are common problems. Foot pain and problems can be due to any number of causes, and in many cases pain may be eased without medication or doctor visits; however, it is always a good idea to rule out any serious medical issues first with a physician.

Stretching may help relax the feet and alleviate pain at any time, but it is especially important before    heavy aerobic exercise to avoid painful cramps or straining muscles in the feet. Stretches should be performed slowly and deliberately without forceful pulling. The stretch should be held for several seconds, and then relaxed.

 

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, 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 the 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 regular stretching every day should be able to minimize foot pain and prevent new problems from arising.

Every Day Foot Care

Our feet are of great importance in our everyday lives. The problem is that we tend to neglect them. When this becomes a habit, it can cause significant trouble. Ignoring foot problems can mean pain, limited mobility, and expensive doctor's visits. On the other hand, if the feet are cared for and looked after each day, they will perform without pain or complication.

 

Routine hygiene is the most basic way to care for the feet. Wash and dry them thoroughly everyday. Remember to get between the toes, and keep the toenails trimmed and short. If the feet feel dry or one can see visual signs of dryness or cracking, use a moisturizer designed for the feet.

 

When using moisturizer on the feet, try to avoid applying between the toes. If creams or lotions sit in that area, they can cause development of fungi and bacteria. When moisturizer is used between the toes, it can also cause the skin to macerate.

 

Shoes are also an important aspect of foot care to consider. When one is picking out shoes, make sure that they are the correct size. Shoes need to be snug, but not too tight. On the other hand, if the shoes are too loose they can cause foot problems as well. It is highly recommended that shopping for new shoes be done later in the day. The reason for this is that the feet will have settled and swelled to their full size by then. To keep your feet at their most healthy, avoid wearing high heels or flip flops too often. Instead, choose shoes that are good for your feet, and that pad the soles of your feet and support the arches and ankles.

 

Socks should also be worn daily with closed-toe shoes. They may feel hot during the summer months, but they absorb sweat and moisture and keep it off the feet. Without socks, the build up of sweat in a closed-toe she can cause fungi problems and athlete's foot.

 

The best thing to remember in every day foot care is that shoes do make a difference. If you spend much time on your feet, make sure that your shoes show no signs of wear and offer ample support for the arches and the overall foot. Additionally, try to engage in thorough foot cleaning and maintenance a part of your daily routine. If you keep these things in mind, your feet will stay healthy and safe.

About Plantar Warts

The term plantar means relating to the foot, which is why plantar warts are only found on the feet. Plantar warts are caused by the human papillomavirus (HPV) getting into open wounds on the feet. These warts are recognizable by a hard bump on the foot. They are mostly found heels or on the balls of the feet. Plantar warts are basically harmless, and may be ignored unless they cause pain or embarrassment.

 

If you have a plantar wart you may notice some pain when standing, or just some tenderness on the sole of your foot. You will be able to see a fleshy wart, unless it has grown into the foot behind a callus. Since plantar warts are not cancerous and not dangerous, a podiatrist only needs to be seen if there is excess pain, the warts come back often or persist for some time, or if it affects walking. It is extremely important that people suffering from compromised immune systems or diabetes seek out a physician’s care immediately upon finding a plantar wart on their foot.

 

Doctors can usually easily diagnose plantar warts. The doctor will scrape off a tiny bit of the rough skin to make tiny blood clots visible that make up the inside of these warts. If the doctor is unsure of a diagnosis they may do a biopsy to be certain. Though plantar warts don't often call for treatment, there are many options for combating them if need be. They can be frozen using liquid nitrogen, removed using an electric tool or burned using laser treatment. For a less invasive treatment a topical cream can be used which is available only through a prescription. Over the counter wart medications may help, given enough time and patience.

 

If you prefer to use home remedies an apple cider vinegar soak is believed to help remove the wart. This treatment takes time. Soak your infected foot in the vinegar for 20 minutes before using a pumice stone to remove any loose skin from the wart. Keep the wart covered for protection in between daily treatments.

 

The best way to avoid contracting plantar warts is to avoid walking barefoot in public areas. This includes wearing shoes in public showers also. It is also important to avoid direct contact with warts, as they can be contagious. This means not touching your own warts, as well as those on others.

How to Prevent Running Injuries

Many common running injuries are caused by overuse and overtraining. Several common injuries can occur due to running. When the back of the kneecap starts wearing away and starts causing pain in the knee, this is commonly referred to as runner’s knee. Runner’s knee can occur because of decreased strength in the quadricep muscles or shoes that do not offer proper support to the inside of the forefoot. Runner’s knee usually is treated with strengthening exercises focusing on the quad muscle and sports orthotic. To prevent runner’s knee, efforts should be focused on hip strengthening. Physical therapy is also beneficial in helping to learn the best exercises to heal runner’s knee. To prevent runner’s knee, strengthen the quad muscles to keep the kneecap aligned.

 

Overtraining is one cause of a common running injury called iliotibial band syndrome, which occurs when the iliotibial band gets irritated, causing pain and discomfort to the outside knee area. Another common running injury is known as plantar fasciitis, which occurs when the bone in the foot becomes inflamed and irritated. This injury primarily causes pain in the foot. Causes can include a high arch, incorrect footwear, tight muscles and flat feet. The best way to avoid plantar fasciitis is stretching and proper footwear.

 

Stress fractures are a common injury for runners. These fractures can occur because of overtraining, lack of calcium or running style. In runners, it is common for stress fractures to occur in several locations including the inner bone of the leg, the thighbone, the bone at the base of the spine and the toe bones in the foot. The best approach to preventing stress fractures are proper footwear maintenance and running on a surface with enough “give” to absorb some of the shock produced during running.

 

Besides overtraining, other causes of these common running injuries are poorly fitting footwear, irregular biomechanics, and lack of flexibility and strength. The best way to avoid running injuries is to prevent them. Fortunately, each of these common running injuries can be prevented. To avoid running injuries it is highly recommended to wear only footwear that fits properly and that suits your needs. Running shoes are the only protective gear that runners have to safeguard them from injury; therefore, choosing the correct footwear for running is important. It is important, too, to think about other aspects of your running routine like training schedules, flexibility and strengthening, and tailor them to your needs in order to minimize the possibility of injury. Regular stretching before and after running should be considered also when trying to avoid running injuries. Stretching keeps muscles limber resulting in greater flexibility.

Nerve Disorders of the Foot and Ankle

Similar to well-known nerve disorders in the hands, such as carpal tunnel syndrome, nerve disorders that affect the foot and ankle occur in patients for reasons ranging from stress to genetics. Nerve disorders of the foot should be addressed right away because they may be immobilizing in serious cases. Two of the most common nerve disorders of the foot and ankle are Interdigital Neuroma and Tarsal Tunnel Syndrome.

 

Interdigital Neuroma is caused by localized inflammation of one of the nerves that controls toe sensitivity in the frontal area of the foot. This inflammation is generally only found in the second or third interspace, and any other symptoms similar to Neuroma on other digits should be checked against other disorders. Symptoms include chronic burning or tingling sensations between the affected toes which can, at times, migrate to the toes themselves. This pain is often increased by walking, running, or by wearing shoes that compress the toes, such as high heels. A doctor should be consulted if this pain is chronic and if the symptoms get worse.

 

Typical examinations to determine the presence of Neuroma include radiographs, MRIs, and even bone scans of the affected area. Bone scans are only required if degeneration of bone is suspected, however. Surgery is often not required to alleviate the symptoms of Neuroma, and in many cases functional orthotics can be used to alleviate the stress of constant weight on the affected toes. Surgery is recommended for those patients that suffer from symptoms for 6 months or more, so reporting symptoms early can increase the rate of non-surgical recovery.

 

Tarsal Tunnel Syndrome, a condition that is less common than Interdigital Neuroma, is similar to Carpal Tunnel Syndrome in that it is caused by a compression of the nerve caused by any number of factors (mostly associated with excess pronation). Typically seen in those that have either flatfeet or valgus heel positions, Tarsal Tunnel Syndrome has patients complaining of moderate to severe ankle pain that starts along the bottom of the foot and often proceeds to the calf. Some more extreme cases occur with partial numbness and even atrophy of the foot and surrounding muscles.

 

If there is a good chance that someone has Tarsal Tunnel Syndrome, an EMG test is often used to diagnose the condition. If the diagnosis is positive, an MRI can be used to identify the compression of the nerve. Treatment with NSAIDS, functional orthotics, and rest off of the feet is often prescribed, but again, long standing symptoms require surgery, as do exacerbated symptoms caused by lesions present between nerves.
