Flat feet can be diagnosed by visual examination of the feet, especially when the child is standing. A child's pediatrician can diagnose flat feet during a visit. X-rays may be taken of the foot to rule out bone changes. It can also be diagnosed by an orthopedic surgeon, although a visit to an orthopedic surgeon is only necessary if surgical repair is being considered, or if pain is a serious issue. How are flat feet treated? Jan 24, 2011 By Jill Leviticus Photo Caption Teenagers who have flat feet may experience pain or cramping. Photo Credit Jupiterimages/Comstock/Getty Images The prolonged and hectic use of the knees without intervals can cause the damage to the cartilage. Take note that any physical activity such as training or work out that is done without pausing can wear out the cushioning effect of the cartilage and therefore cause the pain in the kneecap. Strong muscles play a vital role in the elimination of runner's knee. Your knee joints and muscles must be able to cope up with the stress that is heaped onto the knees. A bigger pelvis can also lead to more loose ligaments and weaker muscles. The same holds true for the overweight people. Right Weight ~ The running shoes for men need not be lightweight as such, however, it is strongly suggested that you don't go for heavy running shoes for flat feet. Many brands have heavy weighted shoes. Avoid these shoes as they may put undue pressure on the leg, in general. So Sweat! ~ Men tend to sweat more at the feet, especially, if they are runners. So, the running shoes for flat feet need to have breathing space for men. This is required to avoid sweating as far as possible and avoid skin problems that it might cause. Stiff sole- the sole of the shoe needs to be stiff to resist foot collapse. Many shoes are highly flexible, and this does not help stabilize a flat foot When examining a shoe for purchase, try to bend the sole of the shoe. If it bends towards the middle of the shoe, then the shoe is too flexible. If the sole bends near the toes or the ball of the foot , then the shoe will be more supportive. Also, try to twist the shoe. Grab the front and back of the shoe and try to twist and wring it like a drying towel. Therapy for flat foot is necessary when a person has flattened arches and does not use adequate arch support in their footwear. Adequate support can be accomplished by using orthotic insoles. For treating flat foot, the feet should be evaluated by a medical doctor promptly if sharp pain in the arches or pain in the heels are occurring. Once that has been finished, ultrasound therapy has proven to be effective in treating the pain related to this condition. Given that the situation with flat foot is an overly stretched arch that is flattened, the therapeutic treatment can involve massage, which can help ease the pain.
