Plantar fasciitis is a painful condition affecting the connective tissue that stretches between the heel and the middle of the foot. It is usually caused by overuse, injury or muscular abnormalities. In extracorporeal shockwave therapy, a machine is used to deliver sound waves to the painful area. It is not known exactly how it works, but it is thought that it might stimulate healing of the fascia.
When the foot moves, the plantar fascia stretches and contracts. Plantar fasciitis is caused by the repetitive overstretching of the plantar fascia. If the tension on the plantar fascia is too great, this overstretching causes small tears in the plantar fascia. This in turn causes the plantar fascia to become inflamed and painful. Factors that contribute to the development of plantar fasciitis include having very high arches or flat feet, gender, while anyone can develop plantar fasciitis, it tends to occur more commonly in women, exercises such as running, walking and dancing, particularly if the calf muscles are tight. Activities or occupations that involve walking or standing for long periods of time, particularly on hard surfaces, wearing high heeled shoes or shoes that do not offer adequate arch support and cushioning, being overweight, additional weight increases the tension on the plantar fascia, poor biomechanics, extra tension is placed on the plantar fascia if weight is not spread evenly when standing, walking or running. Some cases of plantar fasciitis may be linked to underlying diseases that cause arthritis, such as ankylosing spondylitis.
Symptoms of the plantar fasciitis include a gradual onset of pain under the heel which may radiate into the foot. Tenderness is usually felt under and on the inside of the heel which is initially worse first in the morning but eases as the foot warms up only to return later in the day or after exercise. Stretching the plantar fascia may be painful.
The health care provider will perform a physical exam. This may show tenderness on the bottom of your foot, flat feet or high arches, mild foot swelling or redness, stiffness or tightness of the arch in the bottom of your foot. X-rays may be taken to rule out other problems.
Non Surgical Treatment
Stabilize the foot by using uniquely placed wedges, deep heel cups, and “posts” (stabilizers). When the foot is stabilized, it is brought back to a neutral or normal alignment. When the foot is in its normal alignment, pronation and supination are reduced or completely corrected, and the abnormal pull on the Plantar Fascia is alleviated. This will allow the Plantar Fascia to begin to heal. When healing occurs, the pain and inflammation gradually subside. Provide the specific amount of arch support that your foot requires. Our custom-made orthotics support not only the arch as a whole, but each individual bone and joint that forms the arch. Whether your arch is flat or abnormally high, our custom-made orthotics will provide the support that you need. When the arch is properly supported, the Plantar Fascia is protected and healing can begin. Aid in shock absorption. The primary shock absorbers of our feet, and therefore our body, are the Plantar Fascia and the arch. To aid these structures, we construct our custom-made orthotics so that they provide semi-flexible support to the arch by “giving” to absorb the shock of each step, rather than our foot absorbing the shock (our orthotics act in the same way a shock absorber does on an automobile). When your weight is removed from the orthotic, the arch returns to its original height since the material we use has a built-in “memory.” This action will help to keep the Plantar Fascia and arch healthy and pain free. Cushion the heel. Our custom-made orthotics use thin, cushiony, durable, materials to cushion and protect the heel. This helps to alleviate painful heels.
More invasive procedures to treat plantar fasciitis are usually sought only after other treatment has failed to produce favorable results. Corticosteroid injections deliver medicine into the injured fascia to reduce pain. However, this treatment may weaken the plantar fascia and result in further damage. In addition, extracorporeal shock wave therapy (ESWT) is a treatment where sound waves are sent through the damaged tissue in order to stimulate the damaged tissue and encourage healing. This method is relatively new in treating plantar fasciitis and your doctor will be able to tell you if it is the right method for you. Lastly, surgery is the last option for those suffering from chronic or severe plantar fasciitis.
Being overweight can place excess pressure and strain on your feet, particularly on your heels. Losing weight, and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet, can be beneficial for your feet. Wearing appropriate footwear is also important. Ideally, you should wear shoes with a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
