Plantar fasciitis, the heel pain caused by irritation of the connective tissue on the bottom of the foot, can be lingering and intractable. A recent study of novice runners found that those who developed plantar fasciitis generally required at least five months to recover, and some remained sidelined for a year or more. Until recently, first-line treatments involved stretching and anti-inflammatory painkillers such as ibuprofen or cortisone. But many scientists now believe that anti-inflammatories are unwarranted, because the condition involves little inflammation. Stretching is still commonly recommended.
Plantar fasciitis is usually not the result of a single event but more commonly the result of a history of repetitive micro trauma combined with a biomechanical deficiency of the foot. Arthritic changes and metabolic factors may also playa part in this injury but are unlikely in a young athletic population. The final cause of plantar fasciitis is “training errors.” In all likelihood the injury is the result of a combination of biomechanical deficiencies and training errors. Training errors are responsible for up to 60% of all athletic injuries (Ambrosius 1992). The most frequent training error seen with plantar fasciitis is a rapid increase in volume (miles or time run) or intensity (pace and/or decreased recovery). Training on improper surfaces, a highly crowned road, excessive track work in spiked shoes, plyometrics on hard runways or steep hill running, can compromise the plantar fascia past elastic limits. A final training error seen in athletics is with a rapid return to some preconceived fitness level. Remembering what one did “last season” while forgetting the necessity of preparatory work is part of the recipe for injury. Metabolic and arthritic changes are a less likely cause of plantar fasciitis among athletes. Bilateral foot pain may indicate a metabolic or systemic problem. The definitive diagnosis in this case is done by a professional with blood tests and possibly x-rays.
Plantar fasciosis is characterized by pain at the bottom of the heel with weight bearing, particularly when first arising in the morning; pain usually abates within 5 to 10 min, only to return later in the day. It is often worse when pushing off of the heel (the propulsive phase of gait) and after periods of rest. Acute, severe heel pain, especially with mild local puffiness, may indicate an acute fascial tear. Some patients describe burning or sticking pain along the plantar medial border of the foot when walking.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.
Non Surgical Treatment
The key for the proper treatment of plantar fasciitis is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation and allow the condition to heal. If you have usually high arches, which can also lead to plantar fasciitis, cushion the heel, absorb shock and wear proper footwear that will accommodate and comfort the foot. Other common treatments include stretching exercises, plantar fasciitis night splints, wearing shoes that have a cushioned heel to absorb shock, and elevating the heel with the use of a heel cradle or heel cup. Heel cradles and heel cups provide extra comfort, cushion the heel, and reduce the amount of shock and shear forces placed during everyday activities.
The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament. Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause nerve damage.
Maintain a healthy weight. This minimizes the stress on your plantar fascia. Choose supportive shoes. Avoid high heels. Buy shoes with a low to moderate heel, good arch support and shock absorbency. Don’t go barefoot, especially on hard surfaces. Don’t wear worn-out athletic shoes. Replace your old athletic shoes before they stop supporting and cushioning your feet. If you’re a runner, buy new shoes after about 500 miles of use. Change your sport. Try a low-impact sport, such as swimming or bicycling, instead of walking or jogging. Apply ice. Hold a cloth-covered ice pack over the area of pain for 15 to 20 minutes three or four times a day or after activity. Or try ice massage. Freeze a water-filled paper cup and roll it over the site of discomfort for about five to seven minutes. Regular ice massage can help reduce pain and inflammation. Stretch your arches. Simple home exercises can stretch your plantar fascia, Achilles tendon and calf muscles.
