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
oneâs 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.
It is common to see patients with Plantar Fasciitis who have been wearing shoes that are too soft and flexible. The lack of support can be stressful on the heel for those patients whoâs feet
arenât particularly stable. If these ill fitting shoes are worn for long enough, the stress will lead to Heel Pain as the inflammation of the fascia persists. Footwear assessment and advice will be
essential in order to get on top of the Plantar Fasciitis. It may surprise some people to learn that high heeled shoes are not the cause of Plantar Fasciitis, although they can cause tight calf
muscles. High arches can lead to Plantar Fasciitis. This is due to the lack of contact under the sole of the foot. Even sports shoes which appear to have good arch support inside are often too soft
and not high enough to make contact with the arch of the foot. Hence, the plantar fascia is unsupported. This can lead to Heel pain and Plantar Fasciitis. Flat feet can lead to Plantar Fasciitis.
Flat feet is caused by ligament laxity and leads to foot instability. Other structures such as muscles, tendons and fascia work harder to compensate for this instability. Heel pain or Plantar
Fasciitis arises when the instability is too great for these other structures to cope with. The strain on the fascia is too severe and the inflammation sets in. Over stretching can lead to Plantar
Fasciitis. Certain calf stretches put the foot into a position that creates a pulling sensation through the sole of the foot. This can cause Plantar Fasciitis which can cause pain in the arch of the
foot as well as Heel Pain.
Patients with plantar fasciitis typically experience pain underneath the heel and along the inner sole of the foot. In less severe cases, patients may only experience an ache or stiffness in the
plantar fascia or heel that increases with rest (typically at night or first thing in the morning) following activities which place stress on the plantar fascia. These activities typically include
standing, walking or running excessively (especially up hills, on uneven surfaces or in poor footwear such as thongs), jumping, hopping and general weight bearing activity. The pain associated with
this condition may also warm up with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting
performance. In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Patients with this condition may also experience swelling, tenderness on firmly touching
the plantar fascia (often on a specific spot on the inner aspect of the heel) and sometimes pain on performing a plantar fascia stretch.
X-rays are a commonly used diagnostic imaging technique to rule out the possibility of a bone spur as a cause of your heel pain. A bone spur, if it is present in this location, is probably not the
cause of your pain, but it is evidence that your plantar fascia has been exerting excessive force on your heel bone. X-ray images can also help determine if you have arthritis or whether other, more
rare problems, stress fractures, bone tumors-are contributing to your heel pain.
Non Surgical Treatment
In the early stages of plantar fasciitis resting the foot may ease the pain. Medication to reduce inflammation should help but should only be used short term. Strapping may temporarily reduce the
pain. All of the above therapies are only temporary measures and the pain is likely to reoccur if the cause of the abnormal pressure which has triggered the plantar fasciitis has not been identified.
In order to establish the cause of the plantar fasciitis a biomechanical assessment may be required.
The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full
function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change
the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament.
Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause
Preventing plantar fasciitis is crucial. There are many choices to help prevent the occurrence of this condition, and keep it from returning. One of the most important is maintaining a healthy weight
in order to reduce tension on the plantar fascia. In addition, shoes are very important, and should fit well and provide ample cushioning and support throughout the heel, arch, and ball of the foot
so that weight is distributed evenly throughout the foot. Try to avoid walking barefoot on hard surfaces and replace old shoes before they wear out, especially shoes that you run or exercise in. When
exercising, start off slow and ease into new routines to prevent sudden or excessive stress on tissue. Lastly, keep your calf muscles and the tissue of your feet stretched. Greater flexibility in the
tissue makes them less susceptible to damage.
