Affecting about 20-30% of the population, flat feet is a condition in which the foot’s arch either drops or never develops. Flat feet is relatively common in babies and small children as a result of the arch not developing. Adults can develop flat feet as a result of injury or pregnancy due to increased elasticity. However, in adults flat feet is usually a permanent condition.
Flat feet can make walking difficult since it places undue stress on the ankles. This stress throws off the general alignment of the legs since flat feet cause the ankles to move inward, causing discomfort. Flat feet can also affect the knees since arthritis is a common condition in that area. Fortunately, in many cases flat feet do not directly cause any pain.
When it comes to runners, there are specific shoes that can help realign the ankles and provide more support while lessening the amount of pronation involved. Running often causes weight shifting very quickly, so it’s important to be informed whether or not you are affected by flat feet. Knowledge about flat feet is crucial, especially when it comes to preventing injuries.
To be able to diagnose flat feet, a test commonly used is known as the wet footprint test. In the wet footprint test, the individual places a flat foot on a surface to generate a footprint. If there is no indication of an arch or any indentations, that person could have flat feet. In any case, if there is a possibility of having flat feet, a podiatrist should be consulted.
Once flat foot has been diagnosed, it can be treated by wearing insoles. There are two types of flat feet. The first type is rigid, where the feet appear to have no arch even if the affected person is not standing. The other condition, known as flexible flat feet, occurs when the arch seems to ‘go away’ when someone is standing but appears while sitting. In the case of flexible flat feet, unless pain is caused by the condition, there is no need for treatment. However, in the case of rigid flat feet or pain involved in flexible flat feet, orthotic insoles and exercises are prescribed to help the arches develop.
Choosing the Right Running Shoe for Your Foot Type
Running may seem like a simple thing to do, but in reality it is a complex movement that puts stress on the ligaments, bones, and joints of the body. Because of this, selecting the correct running shoe is important for increasing performance and avoiding risk of injury. Running shoes should be selected based on your foot type. Considerations such as trail versus road shoes are important, but your foot type dictates the degree of cushioning, stability and motion control you require. The most accurate way to learn your foot type is to visit a local shop that specializes in running shoes. Professionals there can measure your arch type, stride and gait and let you know your shoe needs for future reference.
The design of running shoes is created around the idea of pronation. Pronation is the rolling of your ankle from outside to inside when your foot strikes the ground, which is natural. If you run properly you strike the ground on the outside of your heel and roll in the direction of your big toe before pushing off once more. Pronation is beneficial because it assists the lower half of your body in absorbing shock and storing energy. Those considered neutral runners pronate correctly and do not need running shoes that help correct their form. Neutral runners can choose from a wide variety of shoes, including barefoot or minimal types. However, those who have arch problems or who adopt an incorrect form while running may experience too much or too little pronation and require running shoes that offer additional support.
Those who overpronate experience an over-abundance of ankle rolling. Even while standing, those who severely overpronate display ankles that are angled inward. It is not uncommon for them to have flat feet or bowed legs as well. The tendency to overpronate may cause many injuries. Areas that tend to become injured are the knees, ankles, and Achilles tendon. If you find that you have a tendency to overpronate, you should look at shoes that provide extra stability and motion-control. Motion-control shoes are straight and firm; shoes of this type do not curve at the tip. The restricted flexibility along the middle of the shoe prohibits the foot from rolling too far inward as your foot strikes.
A less common problem is underpronation. Underpronation, also called supination, is when the feet are unable to roll inward during landing. Those who underpronate have feet that lack flexibility and high arches. This prevents any kind of shock absorption, even though it does place less rotational stress on ankles and knees. This added force can cause fractures, ligament tears, and muscle strains because the legs are trying to compensate for the impact. Those who underpronate need shoes with more cushioning and flexibility. If you have a tendency to underpronate, selecting stability or motion-control shoes may cause you more problems by continuing to prevent pronation.
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.
Biomechanics in Podiatry
Biomechanics and its related study deal with forces that act against the body and effect things like our movement. In podiatry, biomechanics are studied to determine the movement of the ankle, toes, and the foot itself, 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 and limit the mobility everyone takes for granted. Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area, all effecting 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 claimed that changing or controlling the forces between the ankle and the foot, 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 thermoplastic 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 not only take readings, but 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 is 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, so speaking with your podiatrist if you have any of these problems is highly recommended.
