Most people (approx. 60-70% of the population) suffer from excessive pronation due to flat feet when walking, running and standing. Though the foot may appear normal when sitting down, with a clear arch present under the foot, over-pronation becomes noticeable when we stand or walk as a result of weight bearing. The arches collapse with every step we take, and the ankles roll inwards. This is called overpronation, a biomechanical imbalance that can lead to many painful foot conditions such as heel pain, plantar fasciitis, heel spurs, tendonitis, and can even affect other parts of your body such as the knees and lower back.
Flat feet in adults can appear for a number of reasons. Arches never developed properly. Damage to the tendons that support the arch. Damage or inflammation of the posterior tibial tendon which runs from your lower leg, down and across your ankle, and connects to the middle of the arch. Trauma involving broken bones in the foot. Rheumatoid arthritis. Aging, pregnancy, nerve damage, obesity or even diabetes.
Flat feet can cause a myriad of symptoms, from experiencing pain in the foot, heels, arch, calves, the shin, the knee, the hip and into the lower back due to overworking of the hip flexors or they may find it hard to stand on tip toes.
People who have flat feet without signs or symptoms that bother them do not generally have to see a doctor or podiatrist about them. However, if any of the following occur, you should see your GP or a podiatrist. The fallen arches (flat feet) have developed recently. You experience pain in your feet, ankles or lower limbs. Your unpleasant symptoms do not improve with supportive, well-fitted shoes. Either or both feet are becoming flatter. Your feet feel rigid (stiff). Your feet feel heavy and unwieldy. Most qualified health care professionals can diagnose flat feet just by watching the patient stand, walk and examining his/her feet. A doctor will also look at the patient's medical history. The feet will be observed from the front and back. The patient may be asked to stand on tip-toe while the doctor examines the shape and functioning of each foot. In some cases the physician may order an X-ray, CT (computed tomography) scan, or MRI (magnetic resonance imaging) scan.
Non Surgical Treatment
If you have flat feet and foot pain, especially if one foot is flatter than the other, you should have an evaluation by an orthopedic surgeon . You may have a problem with the posterior tibial tendon , the main tendon that supports the arch. Factors that can contribute to this problem are obesity, diabetes , high blood pressure , certain types of arthritis and athletic overuse. In some cases a shoe insert/orthotic can be used to alleviate the symptoms of flat feet.
Feet that do not respond to the treatments above may need surgery. The surgery will help to create a supportive arch.
