Foot pain affects nearly all people at one time or another. It can also lead to other musculoskeletal problems such as ankle, knee and back pain (Hill et al., 2008). This pain negatively affects one’s quality of life and ability to enjoy workouts and/or maintain a regular program of exercise. One of the most common sources of foot pain is plantar fasciitis, a condition where the connective tissue on the underside of the foot becomes irritated and painful as a result of an injury, overuse or misuse. The plantar fascia is a system of connective tissue that runs from your heel to just behind your toes. During weightbearing activities, such as walking or running, your body weight is transferred onto your foot from your heel to your toes (which results in your toes moving away from your heel). This spreading out of the foot places tension on the plantar fascia because it connects those two parts. If the tension on this structure is too great or is not dispersed evenly, the plantar fascia can develop microtears and become irritated and painful, resulting in a condition called plantar fasciitis.
When some people stand/walk/run/jump their own anatomy in their ankle joint is not ‘sturdy’ enough to cope with the needed stabilisation of their ankle joint when they are weight bearing. So, their ankle rotates to find a point of stability. By the shin twisting in and the ankle rotating downwards to the inside (along with your body weight, the power of some muscles, and of course, gravity) a huge amount of stress is applied to the plantar fascia until it is stressed beyond it’s normal limits and it starts to ‘tighten up’. It is this tightening up of the plantar fascia under this stress that causes the damage that in turn leads to pain…eventually.
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.
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
Treatment for plantar fasciitis includes medication, physical therapy, shock wave therapy, or surgery. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen are used to treat the inflammation and pain of plantar fasciitis, but they won’t cure the condition. Corticosteroids can also be used to ease pain and reduce inflammation. Corticosteroids are applied either as a topical solution in conjunction with a non-painful electric current or through injections to the affected area.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
