Overview
The plantar fascia is a ligament that connects the heel to the toes on the bottom of the foot. It lies just below the skin layers as it passes over the arch of the foot. A common ailment called plantar fasciitis is the result of this ligament becomes inflamed. This can Foot anatomyhappen from injury, physical stress, or sometimes for no obvious reason. The most common point for this inflammation is where this ligament joints the heel bone. Typical symptoms are the pain on the bottom of the foot near the heel usually most intense in the mornings when arising or after a long period with little movement. The pain typically diminishes with movement. Many suffering from plantar fasciitis have heel spurs. Even though they are in the same area they are unrelated and the heel spurs do not cause the plantar fasciitis. Most times heel spurs will not cause pain and in many go undetected unless they have an x-ray for some other reason.
Causes
You are more likely to develop plantar fasciitis if you are Active, sports that place excessive stress on the heel bone and attached tissue, especially if you have tight calf muscles or a stiff ankle from a previous ankle sprain, which limits ankle movement eg. Running, ballet dancing and aerobics. Overweight. Carrying around extra weight increases the strain and stress on your plantar fascia. Pregnant. The weight gain and swelling associated with pregnancy can cause ligaments to become more relaxed, which can lead to mechanical problems and inflammation. On your feet. Having a job that requires a lot of walking or standing on hard surfaces ie factory workers, teachers and waitresses. Flat Feet or High Foot Arches. Changes in the arch of your foot changes the shock absorption ability and can stretch and strain the plantar fascia, which then has to absorb the additional force. Middle-Aged or Older. With ageing the arch of your foot may begin to sag - putting extra stress on the plantar fascia. Wearing shoes with poor support. Weak Foot Arch Muscles. Muscle fatigue allows your plantar fascia to overstress and cause injury. Arthritis. Some types of arthritis can cause inflammation in the tendons in the bottom of your foot, which may lead to plantar fasciitis. Diabetes. Although doctors don't know why, plantar fasciitis occurs more often in people with diabetes.
Symptoms
Plantar fasciitis is characterized by the following signs and symptoms. Acute plantar fasciitis, pain is usually worse in the morning but may improve when activity continues; if the plantar fasciitis is severe, activity will exacerbate the pain, pain will worsen during the day and may radiate to calf or forefoot, pain may be described anywhere from "minor pulling" sensation, to "burning", or to "knife-like", the plantar fascia may be taut or thickened, passive stretching of the plantar fascia or the patient standing on their toes may exacerbate symptoms, acute tenderness deep in the heel-pad along the insertion of the plantar aponeurosis at the medial calcaneal tuberosity and along the length of the plantar fascia, may have localized swelling. Chronic plantar fasciitis, plantar fasciitis is classified as "chronic" if it has not resolved after six months, pain occurs more distally along the aponeurosis and spreads into the Achilles tendon.
Diagnosis
Most cases of plantar fasciitis are diagnosed by a health care provider who listens carefully to your description of symptoms. During an examination of your feet, your health care provider will have to press on the bottom of your feet, the area most likely to be painful in plantar fasciitis. Because the pain of plantar fasciitis has unique characteristics, pain upon rising, improvement after walking for several minutes, pain produced by pressure applied in a specific location on your foot but not with pressure in other areas, your health care provider will probably feel comfortable making the diagnosis based on your symptoms and a physical examination. Your health care provider may suggest that you have an X-ray of your foot to verify that there is no stress fracture causing your pain.
Non Surgical Treatment
First check your shoes for too much midfoot flexibility and check your training for changes. A detailed evaluation of changes in your training is necessary. You should start with what is called "relative rest" which means a decrease in workout intensity, duration of session and decrease in the number of sessions per week. The most important part of self treatment for this condition is being sure that your shoes offer sufficient stability and are optimal in controlling the forces that contribute to plantar fasciitis and heel spurs. Check your running shoes to make sure that they are not excessively worn. They should bend only at the ball of the foot, where your toes attach to the foot. This is vital! Avoid any shoe that bends in the center of the arch or behind the ball of the foot. It offers insufficient support and will stress your plantar fascia. The human foot was not designed to bend here and neither should a shoe be designed to do this. You should also be doing gentle calf stretching exercises. This will reduce stress on the plantar fascia in two ways. The first manner in which a relaxation of the tension in the calf muscles can help heel pain is that it will reduce the direct pull backwards on the heel bone (calcaneus). The second reason is a little bit more complicated, but essentially it is that a tight achilles tendon and calf muscles causes the rearfoot to move in a manner that causes over pronation as your leg and body move forward over your foot. So go ahead and gently stretch the calf muscle by doing the runner's wall leaning stretch. To strengthen the muscles in your arch toe curls or "doming" can be done. Toe curls may be done by placing a towel on a kitchen floor and then curling your toes to pull the towel towards you. This exercise may also be done without the towel against the resistance of the floor.
Surgical Treatment
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
Stretching Exercises
The following exercises are commonly prescribed to patients with this condition. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 2 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate and advanced exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head until you feel a stretch in the back of your calf, Achilles tendon, plantar fascia or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Resistance Band Calf Strengthening. Begin this exercise with a resistance band around your foot as demonstrated and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free.
