Orthotics is a medical field concerned with the design, manufacture and use of aids used to support weak limbs or direct the proper function of limbs, in this case the foot and ankle. Ankle-foot orthotics, or AFOs, are braces worn at the ankle that encompass some or all of the foot. Diseases that affect the musculature or weaken the affected area require AFOs to strengthen the muscles or train in the proper direction. Tight muscles that need to be lengthened and loosened also benefit from AFOs.

When we think of diseases that affect the musculature we think of the big boys: muscular dystrophy, cerebral palsy, polio and multiple sclerosis. We rarely think that arthritis and stroke can affect the musculature or that there are some who "toe in". But whatever trauma affects that musculature, there is a way to correct it. The orthosis helps to control range of motion, provide support by stabilizing walk, correct deformities and manage pain load. A podiatrist would be consulted for those who "toe in", for instance, or an arthritis sufferer whose ankles suffer through walking on the job or perhaps a victim of stroke whose musculature is wasting away and requires strength.

Before the advent of modern orthotic devices, it wasn’t uncommon to see polio victims wearing metal braces from mid thigh to the bottom of the foot, or children who "toed in" wearing metal braces around their ankle and foot. However, both designs and materials have improved dramatically, allowing for new levels of comfort, functionality, and appearance. Many orthotics are now made from plastics in the shape of an L and designed to fit inside a corrective shoe. These can be rigid, buckling at the calf and extending the length of the foot to support the ankle. This same design except with a hinged ankle provides support while walking by normalizing the gait. In the past boots lined with leather and fiberboard provided the rigidity needed for correction and support. Now corrective shoes are available with built up soles to correct the gait or manage pain by sharing it with another area when the foot spreads during walking.

The podiatrist would prescribe this orthosis in the rigid L shape because the foot moves on a hinge. If the hinge isn't functioning as intended due to an injury or malformation, the muscles tighten up, thus making it difficult to flex the foot. When we walk, the foot flexes and muscles stretch. This brace or AFO would support the ankle and musculature during flexion of the foot, in much the same way a knee brace works. Corrective shoes are for people whose feet hit the ground backward, causing tight muscles and arch problems. Wedges and rocker bars on the heels correct the step to heel first and rock onto the ball of the foot, resulting in relaxed musculature and strengthened ankles.

Appearance also counts when we consider a particular support device, especially if the item is intended for regular, daily wear. The L shaped orthotic is contoured to the calf and flesh-colored, fitting into a sneaker or dress shoe. As present, corrective shoes are more attractive than past models, enabling patients wear such devices with greater comfort and confidence.

 

Women have been wearing various kinds of high-heels for hundreds of years, mostly for aesthetic reasons. Shoes with heels make their wearer appear to be taller and to have longer and thinner legs, and change the wearer’s gait and posture. High-heels’ association with femininity have kept them popular over the years, but there are definite health problems caused by wearing high-heels too frequently.

High heels also limit the motion of the ankle joints as well when they are worn. The ankle is a very important joint in the body when it comes to walking. These joints have a great deal of weight put on them because of their location. This is why it is so important to keep them as healthy as possible. The main tendon in the ankle is the Achilles tendon. Studies have shown that wearing high heels often causes the calf muscle and Achilles tendon to shorten, and stiffens the Achilles tendon as well, which can cause problems when shoes without heels are worn.

By forcing the toes into a small toe box, and putting a great deal of pressure on the ball of the foot, high-heels can cause or worsen many foot problems, such as corns, hammertoe, bunions, Morton’s neuroma and plantar fasciitis. 

Wearing high-heels regularly, especially very high ones, can have long term negative effects on many other parts of the body, as well as the feet. One of the most important joints in the entire body, the knees, can be affected by wearing high heels. Wearing high heels causes the knees to stay bent at all times. It also causes them to bend slightly inward as well. Many doctors believe that constantly walking like this is the reason that women are so much more likely to suffer from osteoarthritis later in life. High-heels also cause increased stress on the knees by limiting the natural motion of the foot during walking.

The back may also be negatively affected by high heels because this shoe style causes the back to go out of alignment. This affects the spine’s ability to absorb shock, and can cause continued pain in the back if high heels are worn constantly. High-heels also compress the vertebrae of the lower back, and can cause overuse of the muscles in the lower back.

This is not to say that high heels should never be worn. They will not cause serious problems if they are worn only occasionally. However, they should not be worn every day in order to avoid long term physical health problems to the feet, knees, ankles and back.
