The plantar fascia is a thick fibrous band that runs the length of the sole of the foot. The plantar fascia helps maintain the complex arch system of the foot and plays a role in one’s balance and the various phases of gait. Injury to this tissue, called plantar fasciitis, is one of the most disabling running injuries and also one of the most difficult to resolve. Plantar fasciitis represents the fourth most common injury to the lower limb and represents 8 -10% of all presenting injuries to sports clinics (Ambrosius 1992, Nike 1989). Rehabilitation can be a long and frustrating process. The use of preventative exercises and early recognition of danger signals are critical in the avoidance of this injury.
Plantar fasciitis symptoms are usually exacerbated via “traction” (or stretching) forces on the plantar fascia. In simple terms, you plantar fascia is repeatedly overstretched. The most common reason for the overstretching are an elongated arch due to either poor foot biomechanics (eg overpronation) or weakness of your foot arch muscles. Compression type plantar fascia injuries have a traumatic history. Landing on a sharp object that bruises your plantar fascia is your most likely truma. The location of plantar fasciitis pain will be further under your arch than under your heel, which is more likely to be a fat pad contusion if a single trauma caused your pain. The compression type plantar fasciitis can confused with a fat pad contusion that is often described as a “stone bruise”.
Plantar fasciitis is the inflammation of the plantar fascia – a band of tough fibrous tissue running along the sole of the foot. It occurs when small tears develop in the plantar fascia, leading to inflammation and heel pain. The plantar fascia tissue branches out from the heel like a fan, connecting the heel bone to the base of the toes. When the foot moves, the plantar fascia stretches and contracts. The plantar fascia helps to maintain the arch of the foot in much the same way that the string of a bow maintains the bow’s arch. The most notable symptom of plantar fasciitis is heel pain. This is typically most severe in the middle of the heel though it may radiate along the sole of the foot. The pain is most often felt when walking first thing in the morning or after a period of rest. As walking continues the pain may decrease; however some degree of pain remains present on movement. The pain may disappear when resting, as the plantar fascia is relaxed. Redness, swelling and warmth over the affected area may also be noticed. The onset of plantar fasciitis is gradual and only mild pain may be experienced initially. However, as the condition progresses the pain experienced tends to become more severe. Chronic plantar fasciitis may cause a person to change their walking or running action, leading to symptoms of discomfort in the knee, hip and back.
Plantar fasciosis is confirmed if firm thumb pressure applied to the calcaneus when the foot is dorsiflexed elicits pain. Fascial pain along the plantar medial border of the fascia may also be present. If findings are equivocal, demonstration of a heel spur on x-ray may support the diagnosis; however, absence does not rule out the diagnosis, and visible spurs are not generally the cause of symptoms. Also, infrequently, calcaneal spurs appear ill defined on x-ray, exhibiting fluffy new bone formation, suggesting spondyloarthropathy (eg, ankylosing spondylitis, reactive arthritis. If an acute fascial tear is suspected, MRI is done.
Non Surgical Treatment
Although there is no single cure, many treatments can be used to ease pain. In order to treat it effectively for the long-term, the cause of the condition must be corrected as well as treating the symptoms. Rest until it is not painful. It can be very difficult to rest the foot as most people will be on their feet during the day for work. A plantar fasciitis taping technique can help support the foot relieving pain and helping it rest. Plantar fasciitis tapingApply ice or cold therapy to help reduce pain and inflammation. Cold therapy can be applied for 10 minutes every hour if the injury is particularly painful for the first 24 to 48 hours. This can be reduced to 3 times a day as symptoms ease. Plantar fasciitis exercises can be done if pain allows, in particular stretching the fascia is an important part of treatment and prevention. Simply reducing pain and inflammation alone is unlikely to result in long term recovery. The fascia tightens up making the origin at the heel more susceptible to stress. Plantar fasciitis night splint. Plantar fasciitis night splint is an excellent product which is worn overnight and gently stretches the calf muscles preventing it from tightening up overnight.
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.
Do your best to maintain healthy weight. Plantar fasciitis is caused by wear and tear on your feet. Being overweight drastically increases the pounding your feet take every day. Even losing a few pounds can help reduce heel pain. Avoid jobs that require walking or standing for long periods of time. Having your body weight on your feet all day puts a lot of pressure on your plantar fascia tissue. Replace your shoes on a regular basis. Buy new shoes when the old ones are worn-out. Make sure your shoes will fit your foot size comfortably at the end of the day. Pay attention to the width as well as the length. Use good supportive shoes that will help you with your original problem like arch support, motion control, stability, cushioning etc. Stretch regularly as part of your daily routine. There are a few special stretching techniques for the prevention. Choose soft surfaces for your exercise routine to walk, jog or run on. Rest and elevate your feet every chance you have. Strengthen your foot muscles as part of your exercise routine. Strong foot muscles provide a good support to the plantar fascia. Change your shoes during the work week. Don’t wear the same pair of shoes every day. Perform Warm up exercises such as a short period of walking, a light jog or other easy movement and then stretch before starting the main exercise. Try to avoid dramatic changes in your exercise routine. Increase your exercise level gradually. Don’t run long distance if you are used to walk. Make the change slowly and gradually. Pay attention to your foot pain, do not ignore it. Visit your doctor if the pain continues. Avoid the activities that cause you pain. Use over-the-counter Orthotics or inserts that your doctor may prescribe. Off-the-shelf or custom-fitted arch supports (orthotics) will help distribute pressure to your feet more evenly. Try to avoid barefoot walking, since it may add stress on the plantar fascia ligament.
