Plantar fasciitis is a poorly understood condition. There is little consensus among medical professionals about what causes the problem, and no treatments have been reliably proven to treat it. A number of theories exists for why plantar fasciitis develops, but the ineffectiveness of conventional treatments suggests something is missing. The plantar fascia is a band of connective tissue that runs along the underside of the foot from the heel to the toes. The fascia helps maintain the integrity of the arch, provides shock absorption, and plays an important role in the normal mechanical function of the foot.
Plantar fasciitis tends to strike those who overtrain, neglect to stretch their calf muscles, or overdo hill work and speedwork. Plantar fasciitis can also be caused by biomechanical flaws, including flat, high-arched feet and a tight Achilles tendon; excessive pronation; sudden increases in training mileage; beginning speedwork; wearing worn running shoes; running on hard surfaces, like asphalt or concrete; or wearing high heels all day before switching into flat running shoes.
Pain tends to start gradually, often just in the heel, but it can sometimes be felt along the whole of the plantar fascia. The symptoms are initially worse in the morning and mostly after, rather than during, activity. As the condition becomes worse, the symptoms become more persistent.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
To alleviate the stress and pain on the fascia, the person can take shorter steps and avoid walking barefoot. Activities that involve foot impact, such as jogging, should be avoided. The most effective treatments include the use of in-shoe heel and arch cushioning with calf-stretching exercises and night splints that stretch the calf and plantar fascia while the patient sleeps. Prefabricated or custom-made foot orthotics may also alleviate fascial tension and symptoms. Other treatments may include activity modifications, NSAIDs, weight loss in obese patients, cold and ice massage therapy, and occasional corticosteroid injections. However, because corticosteroid injections can predispose to plantar fasciosis, many clinicians limit these injections. For recalcitrant cases, physical therapy, oral corticosteroids, and cast immobilization should be used before surgical intervention is considered. A newer form of treatment for recalcitrant types of plantar fasciosis is extracorporeal pulse activation therapy (EPAT), in which low-frequency pulse waves are delivered locally using a handheld applicator. The pulsed pressure wave is a safe, noninvasive technique that stimulates metabolism and enhances blood circulation, which helps regenerate damaged tissue and accelerate healing. EPAT is being used at major medical centers.
Surgery is rarely used in the treatment of plantar fasciitis. However it may be recommended when conservative treatment has been tried for several months but does not bring adequate relief of symptoms. Surgery usually involves the partial release of the plantar fascia from the heel bone. In approximately 75% of cases symptoms are fully resolved within six months. In a small percentage of cases, symptoms may take up to 12 months to fully resolve.
Exercises designed to stretch both your calf muscles and your plantar fascia (the band of tissue that runs under the sole of your foot) should help relieve pain and improve flexibility in the affected foot. A number of stretching exercises are described below. It’s usually recommended that you do the exercises on both legs, even if only one of your heels is affected by pain. This will improve your balance and stability, and help relieve heel pain. Towel stretches. Keep a long towel beside your bed. Before you get out of bed in the morning, loop the towel around your foot and use it to pull your toes towards your body, while keeping your knee straight. Repeat three times on each foot. Wall stretches. Place both hands on a wall at shoulder height, with one of your feet in front of the other. The front foot should be about 30cm (12 inches) away from the wall. With your front knee bent and your back leg straight, lean towards the wall until you feel a tightening in the calf muscles of your back leg. Then relax. Repeat this exercise 10 times before switching legs and repeating the cycle. You should practise wall stretches twice a day. Stair stretches. Stand on a step of your stairs facing upstairs, using your banister for support. Your feet should be slightly apart, with your heels hanging off the back of the step. Lower your heels until you feel a tightening in your calves. Hold this position for about 40 seconds, before raising your heels back to the starting position. Repeat this procedure six times, at least twice a day. Chair stretches. Sit on a chair, with your knees bent at right angles. Turn your feet sideways so your heels are touching and your toes are pointing in opposite directions. Lift the toes of the affected foot upwards, while keeping the heel firmly on the floor. You should feel your calf muscles and Achilles tendon (the band of tissue that connects your heel bone to your calf muscle) tighten. Hold this position for several seconds and then relax. Repeat this procedure 10 times, five to six times a day. Dynamic stretches. While seated, roll the arch of your foot (the curved bottom part of the foot between your toes and heel) over a round object, such as a rolling pin, tennis ball or drinks can. Some people find that using a chilled can from their fridge has the added benefit of helping to relieve pain. Move your foot and ankle in all directions over the object for several minutes. Repeat the exercise twice a day.
