Plantar Fasciitis is the Latin term for "inflammation of the plantar fascia". The plantar fascia is a thick, fibrous ligament that runs under the foot from the heel bone to the toes. It forms the arch of the foot and functions as our natural shock-absorbing mechanism. Unlike muscle tissue, the plantar fascia is not very elastic and therefore is very limited in its capacity to stretch or elongate. Herein lies the problem, when too much traction is placed on the plantar fascia (for various reasons) micro-tearing will occur, resulting in irritation, inflammation and pain. Plantar Fasciitis usually causes pain under the heel. However some people may experience pain under the arch of the foot. Both heel pain and arch discomfort are related to Plantar Fasciitis, with heel pain being far more common than arch pain.
Plantar Fasciitis often leads to heel pain, heel spurs, and/or arch pain. The excessive stretching of the plantar fascia that leads to the inflammation and discomfort can be caused by the following: Over-pronation (flat feet) which results in the arch collapsing upon weight bearing A foot with an unusually high arch A sudden increase in physical activity Excessive weight on the foot, usually attributed to obesity or pregnancy Improperly fitting footwear Over-pronation (flat feet) is the leading cause of plantar fasciitis. Over-pronation occurs in the walking process, when a person's arch collapses upon weight bearing, causing the plantar fascia to be stretched away from the heel bone. With Plantar Fasciitis, the bottom of your foot usually hurts near the inside of the foot where the heel and arch meet. The pain is often acute either first thing in the morning or after a long rest, because while resting the plantar fascia contracts back to its original shape. As the day progresses and the plantar fascia continues to be stretched, the pain often subsides.
Plantar fasciitis is usually found in one foot. While bilateral plantar fasciitis is not unheard of, this condition is more the result of a systemic arthritic condition that is extremely rare in an athletic population. There is a greater incidence of plantar fasciitis in males than females (Ambrosius 1992). While no direct cause could be found it could be argued that males are generally heavier which, when combined with the greater speeds, increased ground contact forces, and less flexibility, may explain the greater injury predisposition. The most notable characteristic of plantar fasciitis is pain upon rising, particularly the first step out of bed. This morning pain can be located with pinpoint accuracy at the bony landmark on the anterior medial tubercle of the calcaneus. The pain may be severe enough to prevent the athlete from walking barefooted in a normal heel-toe gait. Other less common presentations include referred pain to the subtalar joint, the forefoot, the arch of the foot or the achilles tendon (Brantingham 1992). After several minutes of walking the pain usually subsides only to re turn with the vigorous activity of the day's training session. The problem should be obvious to the coach as the athlete will exhibit altered gait and/ or an abnormal stride pattern, and may complain of foot pain during running/jumping activities. Consistent with plantar fascia problems the athlete will have a shortened gastroc complex. This can be evidenced by poor dorsiflexion (lifting the forefoot off the ground) or inability to perform the "flying frog" position. In the flying frog the athlete goes into a full squat position and maintains balance and full ground contact with the sole of the foot. Elevation of the heel signifies a tight gastroc complex. This test can be done with the training shoes on.
Plantar fasciitis is one of many conditions causing "heel pain". Some other possible causes include nerve compression either in the foot or in the back, stress fracture of the calcaneus, and loss of the fatty tissue pad under the heel. Plantar fasciitis can be distinguished from these and other conditions based on a history and examination done by a physician. It should be noted that heel spurs are often inappropriately thought to be the sole cause of heel pain. In fact, heel spurs are common and are nothing more than the bone's response to traction or pulling-type forces from the plantar fascia and other muscles in the foot where they attach to the heel bone. They are commonly present in patients without pain, and frequently absent from those who have pain. It is the rare patient who has a truly enlarged and problematic spur requiring surgery.
Non Surgical Treatment
About 80% of plantar fasciitis cases resolve spontaneously by 12 months; 5% of patients end up undergoing surgery for plantar fascia release because all conservative measures have failed. For athletes in particular, the slow resolution of plantar fasciitis can be a highly frustrating problem. These individuals should be cautioned not to expect overnight resolution, especially if they have more chronic pain or if they continue their activities. . Generally, the pain resolves with conservative treatment. Although no mortality is associated with this condition, significant morbidity may occur. Patients may experience progressive plantar pain, leading to limping (antalgic gait) and restriction of activities such as walking and running. In addition, changes in weight-bearing patterns resulting from the foot pain may lead to associated secondary injury to the hip and knee joints.
Surgery is rarely needed in the treatment of plantar fasciitis. The vast majority of patients diagnosed with plantar fasciitis will recover given ample time. With some basic treatment steps, well over 90% of patients will achieve full recovery from symptoms of plantar fasciitis within one year of the onset of treatment. Simple treatments include anti-inflammatory medication, shoe inserts, and stretching exercises. In patients where a good effort with these treatments fails to provide adequate relief, some more aggressive treatments may be attempted. These include cortisone injections or extracorporeal shock wave treatments.
While it's typical to experience pain in just one foot, massage and stretch both feet. Do it first thing in the morning, and three times during the day. Achilles Tendon Stretch. Stand with your affected foot behind your healthy one. Point the toes of the back foot toward the heel of the front foot, and lean into a wall. Bend the front knee and keep the back knee straight, heel firmly planted on the floor. Hold for a count of 10. Plantar Fascia Stretch. Sit down, and place the affected foot across your knee. Using the hand on your affected side, pull your toes back toward your shin until you feel a stretch in your arch. Run your thumb along your foot--you should feel tension. Hold for a count of 10.
