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 generally occurs over time, rather than being the result of a single event. Micro trauma from repetitive stress to the tissue often combines with a biomechanical deficiency of the foot to produce the condition. In addition, arthritic and metabolic factors may contribute to the development of this injury, (though they are unlikely to affect young athletes). A variety of training errors commonly lead to plantar fasciitis, particularly a rapid increase in either volume or intensity of athletic activity. Volume refers to the distance or time an athlete performs, while intensity refers to the pace of activity and/or the recovery time allowed following performance.
The pain is more intense with your first steps out of bed in the morning or after sitting for a while. The reason for this is that during rest our muscles and ligaments tend to shorten and tighten up. The tightening of the plantar fascia means more traction on the ligament making the tissue even more sensitive. With sudden weight-bearing the tissue is being traumatised, resulting in a stabbing pain. After walking around for a while the ligament warms up, becomes a little bit more flexible and adapts itself, making the pain go way entirely or becoming more of a dull ache. However, after walking a long distance or standing for hours the pain will come back again. To prevent the sudden sharp pain in the morning or after sitting, it is important to give the feet a little warm-up first with some simple exercises. Also, any barefoot walking should be avoided, especially first thing in the morning, as this will damage to the plantar fascia tissue. Aparty from pain in the heel or symptoms may include a mild swelling under the heel. In addition, heel pain is often associated with tightness in the calf muscles. Tight calf muscles are a major contributing factor to Plantar Fasciitis.
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
Rest the foot as much as you can, especially during the beginning of the treatment. Try to avoid unnecessary foot activity like running, or excess standing. Instead, perform exercises that do not put stress on the injured foot, like bicycling or swimming. Apply ice to the painful area a few times a day to reduce inflammation. Try rolling the arch of the foot over a tennis ball or a baseball. A good treatment is rolling the arch of the foot over a frozen soft drink can. This exercise cools and stretches the affected area. You can use over-the-counter pain relievers (ibuprofen, naproxen) to reduce pain and inflammation. Use an over-the-counter arch support or heel support. Avoid walking barefoot, because it may add stress on the plantar fascia. Exercise your feet to make the muscles, ligaments, tendons and other parts stronger. Stronger foot muscles give better support to the plantar fascia preventing it from another injury. Stretching the foot, the plantar fascia and the calf muscles a few times a day is an essential part of treatment and prevention.
Surgery for plantar fasciitis can be very successful in the right patients. While there are potential complications, about 70-80% of patients will find relief after plantar fascia release surgery. This may not be perfect, but if plantar fasciitis has been slowing you down for a year or more, it may well be worth these potential risks of surgery. New surgical techniques allow surgery to release the plantar fascia to be performed through small incisions using a tiny camera to locate and cut the plantar fascia. This procedure is called an endoscopic plantar fascia release. Some surgeons are concerned that the endoscopic plantar fascia release procedure increases the risk of damage to the small nerves of the foot. While there is no definitive answer that this endoscopic plantar fascia release is better or worse than a traditional plantar fascia release, most surgeons still prefer the traditional approach.
