The plantar fascia is made up of 3 distinct parts: the medial, central, and lateral bands. The central plantar fascia is the thickest and strongest section, and this segment is also the most likely
to be involved with plantar fasciitis. In normal circumstances, the plantar fascia acts like a windlass mechanism to provide tension and support through the arch. It functions as a tension bridge in
the foot, providing both static support and dynamic shock absorption.
The most frequent cause is an abnormal motion of the foot called excessive pronation. Normally, while walking or during long distance running, your foot will strike the ground on the heel, then roll
forward toward your toes and inward to the arch. Your arch should only dip slightly during this motion. If it lowers too much, you have what is known as excessive pronation. For more details on
pronation, please see the section on biomechanics and gait. Clinically not only those with low arches, but those with high arches can sometimes have plantar fasciitis. The mechanical structure of
your feet and the manner in which the different segments of your feet are linked together and joined with your legs has a major impact on their function and on the development of mechanically caused
problems. Merely having "flat feet" won't take the spring out of your step, but having badly functioning feet with poor bone alignment will adversely affect the muscles, ligaments, and tendons and
can create a variety of aches and pains. Excess pronation can cause the arch of your foot to stretch excessively with each step. It can also cause too much motion in segments of the foot that should
be stable as you are walking or running. This "hypermobility" may cause other bones to shift and cause other mechanically induced problems.
Most people with plantar fasciitis have pain when they take their first steps after they get out of bed or sit for a long time. You may have less stiffness and pain after you take a few steps. But
your foot may hurt more as the day goes on. It may hurt the most when you climb stairs or after you stand for a long time. If you have foot pain at night, you may have a different problem, such as
arthritis , or a nerve problem such as tarsal tunnel syndrome.
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
If you protect your injured plantar fascia appropriately the injured tissues will heal. Inflammed structures will settle when protected from additional damage, which can help you avoid long-standing
degenerative changes. Plantar fasciitis may take from several weeks (through to many months) to heal while we await Mother Nature to form and mature the new scar tissue, which takes at least six
weeks. During this time period you should be aiming to optimally remould your scar tissue to prevent a poorly formed scar that may become lumpy or potentially re-tear in the future. It is important
to lengthen and orientate your healing scar tissue via massage, gentle stretches, and light active exercises. In most cases, your physiotherapist will identify stiff joints within your foot and ankle
complex that they will need to loosen to help you avoid plantar fascia overstress.A sign that you may have a stiff ankle joint can be a limited range of ankle bend during a squat manoeuvre. Your
physiotherapist will guide you.
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.
Warm up properly. This means not only stretching prior to a given athletic event, but a gradual rather than sudden increase in volume and intensity over the course of the training season. A frequent
cause of plantar fasciitis is a sudden increase of activity without suitable preparation. Avoid activities that cause pain. Running on steep terrain, excessively hard or soft ground, etc can cause
unnatural biomechanical strain to the foot, resulting in pain. This is generally a sign of stress leading to injury and should be curtailed or discontinued. Shoes, arch support. Athletic demands
placed on the feet, particularly during running events, are extreme. Injury results when supportive structures in the foot have been taxed beyond their recovery capacity. Full support of the feet in
well-fitting footwear reduces the likelihood of injury. Rest and rehabilitation. Probably the most important curative therapy for cases of plantar fasciitis is thorough rest. The injured athlete must
be prepared to wait out the necessary healing phase, avoiding temptation to return prematurely to athletic activity. Strengthening exercises. Below are two simple strength exercises to help condition
the muscles, tendons and joints around the foot and ankle. Plantar Rolling, Place a small tin can or tennis ball under the arch of the affected foot. Slowly move the foot back and forth allowing the
tin can or tennis ball to roll around under the arch. This activity will help to stretch, strengthen and massage the affected area. Toe Walking, Stand upright in bare feet and rise up onto the toes
and front of the foot. Balance in this position and walk forward in slow, small steps. Maintain an upright, balanced posture, staying as high as possible with each step. Complete three sets of the
exercise, with a short break in between sets, for a total of 20 meters.
