The American College of Sports and Medicine (1) estimates that the average adult takes between 5,000 and 10,000 steps per day. The brunt of this activity is borne by the bones, muscles and ligaments of the foot. Healthy feet have strong, wonderfully flexible ligaments which are designed to support standing, walking and running. Plantar Fasciitis (pronounced “plantar fash-ee-eye-tis”) is defined as inflammation of, or damage to, one of the most important ligaments in the foot – the plantar fascia. The plantar fascia ligament is located along the sole of your foot. It is made up of fibrous tissue that stretches outward from the heel bone, like a strong piece of elastic, and then branches out across the arch and through the ball area of the foot toward the toes.
Plantar fasciitis most commonly occurs due to repetitive or prolonged activities placing strain on the plantar fascia. It is often seen in runners, or dancers and gymnasts who perform regular activities involving end of range foot and ankle movements. It may also occur in patients who walk excessively, especially up hills or on uneven surfaces. Older patients who spend a lot of time on their feet may also develop the condition. Plantar fasciitis frequently occurs in association with calf muscle tightness, inappropriate footwear, or biomechanical abnormalities, such as excessive pronation (flat feet) or supination (high arches). Occasionally the condition may occur suddenly due to a high force going through the plantar fascia beyond what it can withstand. This may be due to activities such as a sudden acceleration or a forceful jump.
A sharp pain in the center of your heel will most likely be one of the biggest symptoms of plantar fasciitis. A classic sign of plantar fasciitis is when the pain is worst during the first steps you take in the morning.
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
If you walk or run a lot, cut back a little. You probably won’t need to stop walking or running altogether. If you have either flatfeet or a high arch, ask your doctor about using inserts for your shoes called orthotics. Orthotics are arch supports. You will need to be fitted for them. If you are overweight, losing weight can help lessen your heel pain. If your job involves standing on a hard floor or standing in one spot for long periods, place some type of padding on the floor where you stand.
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.
Factors that help prevent plantar fasciitis and reduce the risk of recurrence include. Exercises to strengthen the muscles of the lower leg and ankle. Warming up before commencing physical activity. Maintaining a healthy body weight. Avoiding high heeled footwear. Using orthotic devices such as arch supports and heel raises in footwear, particularly for people with very high arches or flat feet. Daily stretches of plantar fascia and Achilles tendon.
