It is estimated that around 80% of the population suffer from excessive pronation. This condition is common in all types of people from children to the elderly and from top athletes to people with a sedentary lifestyle. The feet become misaligned and combined with poor posture roll inwards to gain ground contact, the arches become flattened producing the condition known as excessive pronation. When the feet are excessively pronated a combination of poor posture and diminished shock absorption results in some areas of the feet being subjected to excessive stress and pressure. This can lead to various conditions including knee and back problems, as well as foot problems and deformities.
Over-pronation has different causes. Obesity, pregnancy, age or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Over-pronation is also very common with athletes, especially runners and most of them nowadays use orthotics inside their shoes. Over-pronation affects millions of people and contributes to a range of common complaints including sore, aching feet, ball of foot pain, heel Pain, achilles tendonitis, bunions, shin pain, tired, aching legs, knee pain and lower back pain. The most effective treatment solution for over-pronation is wearing an orthotic shoe insert. Orthotics correct over-pronation, thereby providing natural, lasting pain relief from many common biomechanical complaints.
Overpronation causes alterations in proper muscle recruitment patterns leading to tightness in the outside of the ankle (lateral gastrocnemius, soleus, and peroneals). This tightness can lead to weakness in the opposing muscles such as the medial gastrocnemius, anterior tibialis, and posterior tibialis. If these muscles are weak, they will not be able to keep the knee in proper alignment, causing the valgus position. All this tightness and weakness can cause pain within the ankle, calf, and knee region. And it can send imbalance and pain all the way up to the upper back, if deep core strength is lacking and can't hold the pelvis in neutral.
If you cannot afford to get a proper gait analysis completed, having someone observe you on a treadmill from behind will give you an idea if you are an overpronator. It is possible to tell without observing directly whether you are likely to be an overpronator by looking at your foot arches. Check your foot arch height by standing in water and then on a wet floor or piece of paper which will show your footprint. If your footprints show little to no narrowing in the middle, then you have flat feet or fallen arches. This makes it highly likely that you will overpronate to some degree when running. If you have low or fallen arches, you should get your gait checked to see how much you overpronate, and whether you need to take steps to reduce the level to which you overpronate. Another good test is to have a look at the wear pattern on an old pair of trainers. Overpronators will wear out the outside of the heel and the inside of the toe more quickly than other parts of the shoe. If the wear is quite even, you are likely to have a neutral running gait. Wear primarily down the outside edge means that you are a supinator. When you replace your running shoes you may benefit from shoes for overpronation. Motion control or stability running shoes are usually the best bet to deal with overpronation.
Non Surgical Treatment
Personal orthotics can be prescribed via your healthcare professional. If finances or insurance are issues, similar and often better options can be purchased online for overpronation. The right walking shoes are also essential. Most shoes cater to neutral foot gaits, unless they specifically state otherwise. That won?t help you if your foot rolls inward. In order to correct the issue, you need shoes with stability or motion control abilities, low heels, deep heel cups, and good arch support.
The MBA implant is small titanium device that is inserted surgically into a small opening between the bones in the hind-mid foot: the talus (ankle bone) and the calcaneus (heel bone). The implant was developed to help restore the arch by acting as a mechanical block that prevents the foot from rolling-in (pronation). In the medical literature, the success rate for relief of pain is about 65-70%. Unfortunately, about 40% of people require surgical removal of the implant due to pain.
Sever's disease, is a musculoskeletal condition occurring in adolescence that symptomatically manifests as posterior heel pain during ambulation. Often participation in physical activity is severely limited resulting in frustration for children and parents alike. Conservative treatment options have included rest, abstinence from athletic activity, heel lifts, foot orthotic devices, ice, and calf-stretching exercise. The authors are proposing arch taping as an additional viable treatment option for controlling heel pain during athletic and other weight-bearing activities in patients with Sever's disease.
The pain of Severs usually occurs because of inflammation and micro-trauma to the growth plate of the heel bone. This can be caused by a sudden increase in activity, running on very hard surfaces, a growth spurt, tight muscles or feet that roll in.
Often the condition is self limiting; meaning as the growth plate fuses to the rest of the heel bone, the pain will subside. However in some cases the child will have so much discomfort that they will be unable to walk comfortably if left untreated. Therefore, heel pain in children should always by evaluated by a physician.
Sever's disease is diagnosed based on a doctor?s physical examination of the lower leg, ankle, and foot. If the diagnosis is in question, the doctor may order X-rays or an MRI to determine if there are other injuries that may be causing the heel pain.
Non Surgical Treatment
If your child is diagnosed with Sever's disease, treatment is fairly straightforward. He or she should avoid any activities that cause a flare-up of heel pain. Treat the pain with ice for 20 minutes, three times a day. If the pain is severe, over-the-counter pain relievers such as acetaminophen or ibuprofen can be used for a short period of time. (Don't use aspirin in a child or teen because it can result in a rare but life-threatening condition called Reye's syndrome.) In some instances, a child might have other foot problems, as well, such as high arches, flat feet, or bowed legs. In these instances, your doctor can recommend an orthotic device to help further prevent the pain related to Sever's disease. One other simple tip that can prevent Sever's disease or speed along recovery is for your child to wear supportive shoes and avoid going barefoot as much as possible.
Stretching exercises can help. It is important that your child performs exercises to stretch the hamstring and calf muscles, and the tendons on the back of the leg. The child should do these stretches 2 or 3 times a day. Each stretch should be held for about 20 seconds. Both legs should be stretched, even if the pain is only in 1 heel. Your child also needs to do exercises to strengthen the muscles on the front of the shin. To do this, your child should sit on the floor, keeping his or her hurt leg straight. One end of a bungee cord or piece of rubber tubing is hooked around a table leg. The other end is hitched around the child's toes. The child then scoots back just far enough to stretch the cord. Next, the child slowly bends the foot toward his or her body. When the child cannot bend the foot any closer, he or she slowly points the foot in the opposite direction (toward the table). This exercise (15 repetitions of "foot curling") should be done about 3 times. The child should do this exercise routine a few times daily.
Overview Adult acquired flatfoot is one of the most common problems affecting the foot and ankle. Treatment ranges from nonsurgical methods, such as orthotics and braces to surgery. Your doctor will create a treatment plan for you based on what is causing your AAFD. Causes Women are affected by Adult Acquired Flatfoot four times more frequently than men. Adult Flatfoot generally occurs in middle to older age people. Most people who acquire the condition already have flat feet. One arch begins to flatten more, then pain and swelling develop on the inside of the ankle. This condition generally affects only one foot. It is unclear why women are affected more often than men. But factors that may increase your risk of Adult Flatfoot include diabetes, hypertension, and obesity. Symptoms PTTD begins with a gradual stretching and loss of strength of the posterior tibial tendon which is the most important tendon supporting the arch of the human foot. Left untreated, this tendon will continue to lengthen and eventually rupture, leading to a progressive visible collapse of the arch of the foot. In the early stages, patients with PTTD will notice a pain and swelling along the inner ankle and arch. Many times, they are diagnosed with ?tendonitis? of the inner ankle. If the foot and ankle are not properly supported during this early phase, the posterior tibial tendon can rupture and devastating consequences will occur to the foot and ankle structure. The progressive adult acquired flatfoot deformity will cause the heel to roll inward in a ?valgus? or pronated direction while the forefoot will rotate outward causing a ?duckfooted? walking pattern. Eventually, significant arthritis can occur in the joints of the foot, the ankle and even the knee. Early diagnosis and treatment is critical so if you have noticed that one, or both, of your feet has become flatter in recent times come in and have it checked out. Diagnosis First, both feet should be examined with the patient standing and the entire lower extremity visible. The foot should be inspected from above as well as from behind the patient, as valgus angulation of the hindfoot is best appreciated when the foot is viewed from behind. Johnson described the so-called more-toes sign: with more advanced deformity and abduction of the forefoot, more of the lateral toes become visible when the foot is viewed from behind. The single-limb heel-rise test is an excellent determinant of the function of the posterior tibial tendon. The patient is asked to attempt to rise onto the ball of one foot while the other foot is suspended off the floor. Under normal circumstances, the posterior tibial muscle, which inverts and stabilizes the hindfoot, is activated as the patient begins to rise onto the forefoot. The gastrocnemius-soleus muscle group then elevates the calcaneus, and the heel-rise is accomplished. With dysfunction of the posterior tibial tendon, however, inversion of the heel is weak, and either the heel remains in valgus or the patient is unable to rise onto the forefoot. If the patient can do a single-limb heel-rise, the limb may be stressed further by asking the patient to perform this maneuver repetitively. Non surgical Treatment Because of the progressive nature of PTTD, early treatment is advised. If treated early enough, your symptoms may resolve without the need for surgery and progression of your condition can be arrested. In contrast, untreated PTTD could leave you with an extremely flat foot, painful arthritis in the foot and ankle, and increasing limitations on walking, running, or other activities. In many cases of PTTD, treatment can begin with non-surgical approaches that may include orthotic devices or bracing. To give your arch the support it needs, your foot and ankle surgeon may provide you with an ankle brace or a custom orthotic device that fits into the shoe. Immobilization. Sometimes a short-leg cast or boot is worn to immobilize the foot and allow the tendon to heal, or you may need to completely avoid all weight-bearing for a while. Physical therapy. Ultrasound therapy and exercises may help rehabilitate the tendon and muscle following immobilization. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Shoe modifications. Your foot and ankle surgeon may advise changes to make with your shoes and may provide special inserts designed to improve arch support. Surgical Treatment Many operations are available for the treatment of dysfunction of the posterior tibial tendon after a thorough program of non-operative treatment has failed. The type of operation that is selected is determined by the age, weight, and level of activity of the patient as well as the extent of the deformity. The clinical stages outlined previously are a useful guide to operative care (Table I). In general, the clinician should perform the least invasive procedure that will decrease pain and improve function. One should consider the effects of each procedure, particularly those of arthrodesis, on the function of the rest of the foot and ankle.
