Plantar Fasciitis

The plantar fascia is actually a thick, fibrous band of connective tissue which originates at the heel bone and runs along the bottom of the foot in a fan-like manner, attaching to the base of each of the toes. A rather tough, resilient structure, the plantar fascia takes on a number of critical functions during running and walking. It stabilizes the metatarsal joints (the joints associated with the long bones of the foot) during impact with the ground, acts as a shock absorber for the entire leg, and helps to lift the longi-tudinal arch of the foot to prepare it for the 'take-off' phase of the gait cycle

medial calcaneal tubercle

Although the fascia is invested with countless sturdy 'cables' of connective tissue called collagen fibres, it is certainly not immune to injury. Plantar fasciitis, the most common cause of heel pain, may have several different clinical presentations. Although pain may occur along the entire course of the plantar fascia, it is usually limited to the inferior medial aspect of the calcaneus, at the medial process of the calcaneal tubercle. Often tend to occur near the heel, where stress on the connective tissue fibres is greatest, and where the fascia itself is the thinnest (it tends to broaden out as it reaches toward the toes). This bony prominence serves as the point of origin of the anatomic central band of the plantar fascia and the abductor hallucis, flexor digitorum brevis and abductor digiti minimi muscles.

Plantar fasciitis is often referred to as "heel spur syndrome" in the literature and the medical community, but the label is a misnomer. This vague and nonspecific term incorrectly suggests that osseous "spurs" (inferior calcaneal exostoses) are the cause of pain rather than an incidental radiographic finding. There is no correlation between pain and the presence or absence of exostoses,1 and excision of a spur is not part of the usual surgery for plantar fasciitis.2 Plantar fasciitis occurs in both men and women, but is more common in the latter. Its incidence and severity correlate strongly with obesity.

Palpation of the medial calcaneal tubercle usually elicits pain in patients presenting with plantar fasciitis.

Causes

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
  • Increased raising of arch such as occurs when shoveling or climbing ladders

Most cases of plantar fasciitis are the result of a biomechanical fault that causes abnormal pronation. This pronation significantly increases tension on the plantar fascia.
Other conditions, such as bowed shins, tight calves, and limb length inequality, can cause an abnormal pronatory force on the long limb. Increased pronation with a collapse produces additional stress on the anatomic central band of the plantar fascia and may ultimately lead to plantar fasciitis.

Symptoms
Patients usually describe pain in the heel on taking the first several steps in the morning, with the symptoms lessening as walking continues. They frequently relate that the pain is localized to an area that the examiner identifies as the medial calcaneal tubercle. The pain is usually insidious, with no history of acute trauma. Many patients state that they believe the condition to be the result of a stone bruise or a recent increase in daily activity. It is not unusual for a patient to endure the symptoms and try to relieve them with home remedies for many years before seeking medical treatment.

Diagnosis
Even in this age of modern technology, the diagnosis of plantar fasciitis is based mainly on the medical history and clinical presentation. Direct palpation of the medial calcaneal tubercle often causes severe pain (see Figure above). The pain is generally localized at the origin of the anatomic central band of the plantar fascia, with no significant pain on compression of the calcaneus from a medial to a lateral direction. Standard weight-bearing radiographs may show other osseous abnormalities such as fractures, tumors or rheumatoid arthritis in the calcaneus. However, radiographs usually serve only as an aid to confirm the clinician's diagnosis.

Conservative Treatment
Conservative treatment of plantar fasciitis should address the inflammatory component that causes the discomfort and the biomechanical factors that produce the disorder. Patients should learn about recommended changes in daily activities, such as wearing appropriate shoes with a significant medial arch while walking. Patients whose symptoms are associated with a recent increase in exercise should adopt a less strenuous regimen until the plantar fasciitis resolves. An ankle/foot strengthening and stretching program will help to prevent recurrence if this is the cause.

To serve as a temporary medial arch support to decrease pronation during midstance of the gait cycle the patient can be fitted with a removable pad or a medial arch pad directly against the patient's skin with taping the patient's foot from a plantar medial to a plantar lateral direction that.These temporary devices provide greater biomechanical support than over-the-counter heel cups or heel pads. If a patient has significant plantar fasciitis pain secondary to a limb-length inequality a simple ¼" heel lift in the shoe of the short limb may provide temporary relief. One-sided tight calf might feel better with a bilateral heel lift.

Orthotic devices are the mainstay of ongoing conservative treatment for patients with plantar fasciitis. The biomechanical factors that cause the abnormal pronatory forces stressing the medial band of the plantar fascia must be corrected. Patients with high arched feet may benefit from using a flexible orthotic device with an additional heel cushion. This prescription orthosis can disperse some of the force experienced on heel strike, while maintaining biomechanical support for propulsion.

Stretching the Achilles tendon and hamstrings is beneficial as adjunctive therapy for plantar fasciitis. This can be done in conjunction with arch stretching by pulling back on the toes or rolling a can or ball back and forth under the arch. Most popular time that this is helpful is prior to rising. Seeing a massage therapist good with fascial stretching techniques can also help.

Each night for 10 to 14 days, the patient should apply an ice pack to the plantar aspect of the heel 15 to 20 minutes before going to bed.or massage the plantar fascia with an ice block (made up of water frozen in a paper cup).

It is often advantageous for patients with no contraindication to take a nonsteroidal anti-inflammatory drug (NSAID) for six to eight weeks. We believe that corticosteroid injections should be avoided in the initial treatment of plantar fasciitis; we recommend themonly as supplemental treatment in patients who have resistant chronic plantar fasciitis after achieving adequate biomechanical control. These injections may provide only temporary relief and can cause a loss of the plantar fat pad if used injudiciously.

Night night splintsplints that maintain the foot at an angle of 90 degrees or more to the ankle have recently been used as adjunctive therapy for plantar fasciitis. These orthoses prevent contraction of the plantar fascia while the patient sleeps. One study showed relief of recalcitrant plantar fasciitis pain in 83 percent of patients treated with such splints.

Shock wave or laser therapy can sometimes help to increase blood flow to stimulate the healing process.
Some clinicians advocate the use of a short-leg walking cast for several weeks as a final conservative step in the treatment of plantar fasciitis.

Bunions

bunionsSeveral features combine to create the infamous bunions that are the plague of every woman who loves to wear tight fashion shoes. Like many of our physical features, bunions tend to be inherited, but get worse with time. Severe bunions can be seen even in 12 year olds, but rarely in males. In the diagram above you can see the big toe joint going out of shape with the typical large bump (subluxed joint and thickened bursa), the widened foot and the end of the toe angling inwards.

The shape of the foot however, does not usually have much to do with the pain of a bunion. Bunion pain is most often caused by the wider foot and its prominent bump rubbing against the side of the shoe. The bursa (a small, flat, fluid-filled sac that lies just below the skin on the outside of the bump), becomes inflamed and thickened. Even shoes that you once thought were loose may be tight enough to create a great deal of pain. Wearing wider shoes usually
eliminates the pain, but the bump makes fitting tight shoes very difficult.

Surgery is the only alternative to reduce the size of the bump and the hallux valgus angle. There are several different procedures which have both pros and cons . Most patients will try other methods of managing the condition initially.

Bunion formation is likely accelerated by hyperpronation (excessive lowering of the arches) because of the excessive weight placed on the big toe joint during the pushoff phase of gait, forcing the hallux into further valgus. More friction between the bursa and the shoe occurs with a hyperpronated foot. Once the hallux valgus angle is significant it destabilizes the foot during push-off since the great toe is not available for push off.

What to Do

The pain of hallux rigidus (osteoarthritis of the great toe) or conditions like gout can sometimes mimic the pain of bunions so see your doctor for a proper assessment. Tight, pointed toeboxes force the hallux into greater valgus for hours at a time and should therefore be used in moderation. Shoes should be devoid of seams since stitching does not stretch easily. Pumps should be high in the vamp, covering the bunion completely, rather that the more classic style that cuts across it. Bunions that ache at night can be relieved with ice and a bunion splint that straightens the toe temporarily.

Constant use of a hallux valgus night splint may reduce the ligamentous contractures associated with long term bunions. Gel toe spreaders may also provide relief. Pre-stretch the bunion area at the shoe repair shop rather than make your foot do the work, or purchase a "ball and ring" stretcher made for that purpose. Wear a heel height that is comfortable, and wear supportive walking or running shoes with a roomy toebox whenever possible. Wear orthotics or arch supports as your doctor prescribes them to control hyperpronation.

Achilles TendonitisAchilles Tendonitis

What is it?

  • The achilles tendon (common tendon for gastrocnemius and soleus muscles, which unite distally to form it in conjunction with the plantaris muscle that lies between the gast. and sol.) is the large tendon located in the back of the leg that inserts into the heel. Achilles tendonitis is an inflammation of that tendon.
  • Achillies tendonitis should not be left untreated due to the danger that the tendon can become weak and ruptured.

Signs and Symptoms

  • Pain and swelling over the tendon and inability to perform.
  • Local tenderness on squeezing the tendon.
  • Crepitus may occur
  • Pain with forced passive dorsiflexion, resistance to active plantar flexion, or both.
  • Often complaint is that the first steps out of bed in the morning are extremely painful. Another common complaint is pain after steps are taken after long periods of sitting. This pain often lessens with activity.

What causes it?

Several factors

  • Achilles tendonitis can develop gradually without a history of trauma or can occur from a sudden injury.
  • The most common causes are training too hard/too soon without proper strengthening.
  • Activities that repeatedly stress the tendon, causing inflammation (such as walking, running or jumping). It is a common problem often experienced by athletes, particularly distance runners.
  • Biomechanical abnormality such as over-pronation
  • Associated with a high-arch (pes cavus) foot type
  • Improper shoes
  • Abnormal stiffness of the calf muscle complex.

Treatment

  • A person suffering from Achilles tendonitis should incorporate a thorough stretching program to properly warm-up the calf muscles.
  • They should also decrease the distance and intensity of their walk or run.
  • Apply ice after the activity.
  • It is best to avoid any up hill climbs, which increases the stress on the Achilles tendon.
  • Heel lifts in the shoes, anti-inflammatory medication, and ultrasound.
  • Casting in extreme cases as last resort.

Pedorthic TreatmentDorsiflexion night splint

  • Achilles tendonitis can be a difficult injury to treat due to high levels of activity and reluctance to stop or slow down training.
  • An orthotic device should be used to accommodate any biomechanical abnormality and allow the Achilles tendon to function more normally.
  • A heel lift may be recommended on a temporary basis to elevate the heel and reduce stress on the Achilles tendon. The device should be made with shock absorbing materials.
  • Dorsiflexion night splints.
  • Shoes that do not place unusual pressure on the Achilles tendon or on its insertion site on the heel will help prevent further injury.

Arthritis

What is it?

Arthritis is a disease characterized by the inflammation of the cartilage and lining of the body's joints. Inflammation causes redness, warmth, pain and swelling. Arthritis is often considered a disease of the aging but can occur at any age. The primary targets for arthritis are people over the age of 50. Arthritis is a major cause of foot pain because each foot has 33 joints that can become affected by the disease. Arthritis causes changes in joints and restriction of motion. These changes and restrictions can make walking painful.

Arthritis is a general term for a variety of conditions that cause inflammation and degeneration of the cartilage and lining of the joints of the body. There are many different kinds of arthritis. Some of the most common types are osteoarthritis and rheumatoid arthritis. The term arthritis refers to more than 100 different rheumatic diseases that affect the joints, muscles, and bones, as well as other tissues and structures. Gout accounts for approximately 5 percent of all cases of arthritis.

What causes it?

Osteoarthritis is typically considered to result from normal "wear and tear" or age, but can also result from previous injury with stiffness usually occurring after periods of rest.

Rheumatoid arthritis can occur at any age and there is no known cause for this condition. It can cause severe deformities of the joints, especially in the hands and feet. It can develop at any age and there is no known cause for this condition. Rheumatoid arthritis is the most crippling form of the disease that can affect people of all ages. It can cause severe deformities of the joints with associated fatigue of the entire body. People who suffer from rheumatoid arthritis often develop severe forefoot problems such as bunions, hammer toes, claw toes, and others.

Pedorthic Treatment

Arthritic footwear should accommodate swelling of the foot. Orthotics designed to provide comfort, support and extra cushioning are also recommended. Orthotics made with a material called Plastazote are often recommended because they mold to your feet to provide customized comfort. The proper footwear and orthotics will reduce pressure to provide a comfortable support base.

Gout

Gout is one of the most painful rheumatic diseases. Our blood contains a salt called uric acid. It results from deposits of excess needle-like crystals of uric acid in connective tissue, in the joint space between two bones, or in both. These deposits lead to inflammatory arthritis, which causes swelling, redness, heat, pain, and stiffness in the joints. The big toe joint is commonly the focal point due to the stress and pressure it experiences during walking and other weight bearing activities. This often leads to severe pain in the big toe. Up to 60% of initial attacks occur at the first metatarsophalangeal joint. Gout mostly affects men and is very rare in women until after menopause when it is seen quite often.

The signs and symptoms of gout are almost always acute, occurring suddenly - often at night - and without warning. They include Intense joint pain swelling, and redness usually affecting the large joint of your big toe but can occur in your feet, ankles, knees, hands and wrists. The pain typically lasts five to 10 days and then stops. The discomfort subsides gradually over one to two weeks, leaving the joint apparently normal and pain-free. After the first attack there may be intervals of many months or even years before there are other attacks. Over time these attacks tend to become more frequent and more severe and eventually may involve other and more joints.

There are many causes of hyperuricaemia (high uric acid levels) which include:

  1. Hereditary or "Primary gout" which is a genetic disorder of uric acid metabolism leading to high levels of serum uric acid. The presence of urate crystals in a joint sets off an immune response that causes the body to attack the internal components of the joint, leading to extreme pain and eventually joint destruction.
  2. Secondary gout (10% of cases) from: catabolism (breakdown) secondary to leukemias and certain other cancers or a very reduced caloric intake; or decreased excretion of uric acid due to renal failure. obesity; some of the drugs used to treat high blood pressure can precipitate a gouty attack; high intake of food that contain purines (purines are broken down into uric acid); an excessive intake of alcohol (particularly beer); the use of diuretics: the use of aspirin; and the low intake of water.

The crystals also have a tendency to form on a roughened surface, such as a joint that has suffered from previous trauma, unreduced subluxation, or degeneration.

Gout Treatment

In the acute and chronic stages, ultrasound, heat, gentle chiropractic manipulative therapy and gentle soft-tissue massage are beneficial.

Diabetes

Definition

  • Diabetes is a serious disease that can develop from lack of insulin production in the body or due to the inability of the body's insulin to perform its normal everyday functions. Insulin is a substance produced by the pancreas gland that helps process the food we eat and turn it into energy.
  • According to the Public Health Agency of Canada, approximately 2 million Canadians have diabetes classified into 2 different types: Type 1 and Type 2. 90% have Type 2. Type 1 is usually associated with juvenile diabetes and is often linked to heredity. Type 2, commonly referred to as adult onset diabetes, is characterized by elevated blood sugars, often in people who are overweight (especially if the weight is concentrated around the mid-section) or have not attended to their diet properly.
  • It's the leading cause of death by disease in North America.
  • With proper nutrition and regular physical activity, you can reduce your risk of getting type 2. Healthy eating and regular physical activity also helps those with diabetes to help manage the disease.
  • Many complications can be associated with diabetes. Diabetes disrupts the vascular system, affecting many areas of the body such as the eyes, kidneys, legs, and feet. People with diabetes should pay special attention to their feet.

How does Diabetes contribute to foot problems?

  • Approximately 40% of people with diabetes will develop complications at some point.
  • There are two types of complications: reduced ability to fight infection and damage to the circulatory system, including both small and large blood vessels.
  • 25% of all diabetic hospitalizations are for the foot.
  • Neuropathy in about 25% of people with diabetes.

Poor Circulation

  • Vascular disease causes a narrowing of the arteries that can lead to significantly decreased circulation in the lower part of the legs and the feet.
  • This decreased circulation reduces the body's ability to heal itself and persons affected by diabetes often develop sores or ulcers that can take months or even years to heal. The lnger a sore is present, the more likely it is that infection can enter the body causing more serious problems.
  • Poor circulation can also lead to swelling and dryness of the foot.
  • Signs of stress in the venous circulation include swelling of the feet and ankles, called "edema", or a brown discoloration of the skin around the ankles and the lower calf, called "staining". Problems with arterial circulation are not associated with edema or staining.

Neuropathy

  • The loss of ability to feel pain, heat and cold. Persons affected by diabetes who have neuropathy can have sores that they are not even aware of due to the insensitivity.
  • A person who has neuropathy has a 60% risk for getting a foot ulcer within the next three years.
  • There are 4 basic ways that ulcers get started if you have neuropathy in your feet. 1) Infection, 2) Big pressure, short time, 3) Little pressure, long time, 4) Medium pressure, again and again.
    1. Infection is caused from bacteria getting into your skin and releasing toxins (harmful chemicals) that eat away at your skin. Red areas, swelling, or warm spots ignored can eventually lead to an ulcer.
    1. Ulcers can get started with a distinct injury like stepping on a nail that breaks the skin. This shows a good case for wearing shoes.
    2. Blanching is when you press on your skin turning it white since you're squeezing out the blood. If you keep this up for several hours, the skin at that point may die because of the lack of nutrition. Examples of this would be wearing to tight of shoes or bedsores.
    3. The most popular cause of ulcers is moderate pressure that is repeated. Particular areas that bear extra weight over 1000's of steps each day will build corns, blisters, and calluses and eventually the skin breaks down in that one area.
  • Even if you don't have neuropathy, you may develop a foot ulcer. You may have hardening of the arteries in your legs and feet. If so, the circulation in your feet is poor. You may develop ischemic ulcers, which are caused by a lack of blood-flow, which are often quite painful. Though, you could have a painless ischemic ulcer if you have neuropathy as well as arteriosclerosis.
  • If these injuries are left untreated, complications could arise leading to ulceration and possibly even amputation. In one study it was shown that 86% of amputations were attributed to initial minor trauma causing tissue injury. 36% of these were caused by repetitive shoe-related pressure.
  • It has been shown that high blood sugars increase the amount and severity of neuropathy of patients with Type 1 diabetes.
  • Neuropathy can also cause deformities such as Bunions, Hammer Toes, and Charcot Feet.

Charcot Foot

  • Charcot Foot is a common complication of diabetic neuropathy that leads to a massively deformed foot that requires special care to prevent ulceration over unusual pressure points.
  • It's been estimated that 2% of people with diabetes develop Charcot's joint.
  • The muscles lose their ability to support the foot correctly. As a result of this, minor trauma (eg sprains; stress fractures) to the foot go undetected and do not get treated. This leads to a slackness of the ligaments (laxity), joints being dislocated, bone and cartilage being damaged and deformity to the foot.
  • The first sign is a warm, red, swollen foot without pain or very little. A x-ray may show broken or eroded bones, or joints that are separated. Later, "rocker-bottom foot" develops: The bones and joints collapse and the arch of you foot disappears. Over time, the broken and degenerated bones fuse together and the foot tries to heal itself. By this time, the inflammation has generally calmed down.
  • In most cases only one foot is affected, but both feet can be affected over time.
  • If treated early a 'total contact cast' worn for 3 - 4 months will prevent you from injuring your foot further. If you develop the rocker-bottom foot, your mid-sole will be bearing most of your weight.

What can you do to protect you feet on a daily basis?

  • Diabetes is the leading cause (accounting for 50%) of all non-accident-related amputations. Research has demonstrated that over 80% of foot ulcers and amputations are preventable by educating people about proper foot care and footwear.
  • Wear shoes and socks (allowing the foot to breathe) at all times, even indoors, to prevent injury.
  • Wear shoes that fit well (roomy but not sloppy).
  • Always check the insides of your shoes for foreign debris before putting them on.
  • Make sure that the lining is smooth and there are no foreign objects in the shoe, such as pebbles.
  • Protect your feet from hot and cold temperatures.
  • Put your feet up when you are sitting. Wiggle your toes for 5 minutes, 2 or 3 times a day. Move your ankles up and down and in and out to improve blood flow in your feet and legs.
  • DO NOT cross your legs for long periods of time.
  • DO NOT wear tight socks, elastic, or rubber bands, or garters around your legs.
  • Keep your skin soft and smooth and trim toenails straight across.
  • Bathe (don't soak) your feet daily in luke-warm water using a mild soap and dry well.
  • Make daily foot checks a routine.
  • Have a professional take care of your nails and skin if you cannot see well.
  • Be sure to call your doctor immediately if a cut, sore, blister or bruise on your foot does not heal after one day.

How can a pedorthist help to treat it?

  • Orthoses and footwear play an important role in foot care for persons affected by diabetes to help prevent serious injury and help an injury to heal.

Materials used for orthotics:

  • Depends on the history of complications such as ulceration and the presence or absence of sensation on the foot:
  • No history of complication and has normal sensation should have an orthotic that will accommodate any abnormal mechanics to alleviate abnormal pressures on the foot.
  • With an ulcer and no sensation requires an orthotic that will redistribute pressure away from the ulcer site and allow it to heal. Plastazote is the most common material designed to accommodate pressure "hot spots" by conforming to heat and pressure to protect the insensitive foot.

Footwear should have the following features:

  • Footwear should have toe box that is shaped like the foot and is deep enough to protect the toes from excessive pressure;
  • Removable insoles are preferred for versatility in fitting, as they can be removed to insert an orthotic if necessary, or modified themselves to relieve pressure;
  • Rocker soles on the shoes help to reduce pressure in the ball of the foot, an area that is susceptible to pressure sores/ulcers;
  • Firm Heel Counters are recommended for support and stability.

Metatarsalgia

MetatarsalgiaFoot pain in the "ball of your foot," that area between your arch and the toes, is generally called metatarsalgia (met'-a-tar-sal'-gee-a). It's a non-specific diagnosis of pain in and about the Metatarsal (MT) head or MTP (Metatarsal/Phalangeal) joint and adjacent soft tissue structures.

Types:

Morton's foot (long 2nd metatarsal), Freiberg's Disease (usually 2nd metatarsal head osteochondritis in young women), Metatarsal stress fractures (hair-line cracks that arise in bone as the result of repeated low-level forces), sesamoiditis (gradual onset of and increasing pain at the plantar aspect of the medial plantar border of the 1st MPJt (metatarsal phalangeal joint) with swelling and decreased ROM (range of motion), Morton's neuromas (usually in heavier women, where the lateral and medial plantar nerves get compressed in the 3rd interdigital space), ganglionic cysts (weak wall of a synovial tendon sheath or jt. capsule), joint capsulitis (frequently secondary to OA (osteoarthritis) and RA(rheumatoid arthritis) or ongoing low-grade Jt. trauma), synovitis (common in RA), flexor tenosynovitis, rheumatoid bursae and nodules (those with RA tend to be very large over the bunion and plantar aspect of MPJts., and fibrinoid nodules over bony prominences), bursitis (shearing of bursa may cause it to become fibrous, distended, inflamed, infected or even calcified), transient ischaemia (nerve and artery serving the affected nerve are compressed during gait by the distal distension of the intermetatarsal bursa), gouty tophus (1st MPJt. Uric acid crystal-idposition), myalgia, neoplastic disease (rare tumours) , plantar plate rupture (from hyperextension @ 1st- turf toe) (tough, rectangular, fibrocartilaginous structure that overlies the plantar aspects of the MPJts), and focal hyperkeratosis (deep seated corns)

Posterior Tibialis Tendonitis

Posterior tibialis tendonitis is an inflammation of the tendon that runs along the inside of the ankle and attaches to the middle of the foot along the inside edge.

The posterior tibial tendon helps hold your arch up and provides support as you step off on your toes when walking. If this tendon becomes inflamed, over-stretched or torn, you may experience pain on the inner ankle and gradually lose the inner arch on the bottom of your foot, leading to flatfoot.

Inflammation may be caused by biomechanical factors such as abnormal pronation that repetitively stretches this muscle and tendon. It can also result from being overweight, or from previous trauma, inflammatory diseases such as rheumatoid arthritis, Reiter's syndrome or psoriatic arthritis. Excessive repetitive force such as running on a banked track or road can also cause the inflammation.

SHIN SPLINTS

Medial Tibial Stress Syndrome includes tendonitis and periosteal irritation involving the posterior tibial muscle and tendon, the flexor muscles and tendons, and other soft tissues attached to the posteromedial border of the tibia. If left untreated this has an increased risk of turning into a stress reaction and stress fracture.

Shin splints can be caused when the anterior leg muscles are stressed by running, especially on hard surfaces or extensively on the toes, or by sports that involve jumping. Wearing athletic shoes that are worn out or don't have enough shock absorption can also cause this condition.

It is important not to try to train through the pain of shin splints. Runners should decrease mileage for about a week and avoid hills or hard surfaces. If a muscle imbalance, poor running form or flat feet are causing the problem, a long-term solution might involve a stretching and strengthening program and orthotics that support the foot and correct over-pronation. In more severe cases, ice massage, electrostimuli, heat treatments and ultra-sound might be used.
