Plantar fasciitis is the most common cause of heel pain. Pain from plantar fasciitis is often most noticeable during the first few steps after getting out of bed in the morning. The plantar fascia is a thick band of tissue in the sole of the foot. Microtearing at the origin of the plantar fascia on the heel bone (calcaneus) can occur with repetitive loading. This microtearing leads to an inflammatory response (healing response) which produces the pain. Risk factors for plantar fasciitis include excessive standing, increased body weight, increasing age, a change in activity level, and a stiff calf muscle. Plantar fasciitis can be managed non-operatively in the vast majority of patients. The main components of an effective non-operative treatment program are: calf stretching with the knee straight, plantar fascia stretching, activity modification (to avoid precipitating activities), and comfort shoe wear.
The plantar fascia can also become aggravated by repetitive activity. If you increase the number of times the heel hits the ground, that can cause plantar fasciitis, a number of people develop problems when their feet are unaccustomed to hard tile or wood floors. Other risk factors for plantar fasciitis include obesity, an extra high or low foot arch, and activities like running.
The most obvious symptom of plantar fasciitis is a sharp pain on the bottom of the foot, near the heel. Here are some signals that this pain may be plantar fasciitis. The pain is strongest first thing in the morning but gets better after a few minutes of walking around. The pain is worse after standing for a long time or after getting up from sitting. The pain develops gradually and becomes worse over time. The pain is worse after exercise or activity than it is during activity. It hurts when stretching the foot. It hurts when pressing on the sides of the heel or arch of the foot.
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
Stabilize the foot by using uniquely placed wedges, deep heel cups, and “posts” (stabilizers). When the foot is stabilized, it is brought back to a neutral or normal alignment. When the foot is in its normal alignment, pronation and supination are reduced or completely corrected, and the abnormal pull on the Plantar Fascia is alleviated. This will allow the Plantar Fascia to begin to heal. When healing occurs, the pain and inflammation gradually subside. Provide the specific amount of arch support that your foot requires. Our custom-made orthotics support not only the arch as a whole, but each individual bone and joint that forms the arch. Whether your arch is flat or abnormally high, our custom-made orthotics will provide the support that you need. When the arch is properly supported, the Plantar Fascia is protected and healing can begin. Aid in shock absorption. The primary shock absorbers of our feet, and therefore our body, are the Plantar Fascia and the arch. To aid these structures, we construct our custom-made orthotics so that they provide semi-flexible support to the arch by “giving” to absorb the shock of each step, rather than our foot absorbing the shock (our orthotics act in the same way a shock absorber does on an automobile). When your weight is removed from the orthotic, the arch returns to its original height since the material we use has a built-in “memory.” This action will help to keep the Plantar Fascia and arch healthy and pain free. Cushion the heel. Our custom-made orthotics use thin, cushiony, durable, materials to cushion and protect the heel. This helps to alleviate painful heels.
Surgery is rarely needed in the treatment of plantar fasciitis. The vast majority of patients diagnosed with plantar fasciitis will recover given ample time. With some basic treatment steps, well over 90% of patients will achieve full recovery from symptoms of plantar fasciitis within one year of the onset of treatment. Simple treatments include anti-inflammatory medication, shoe inserts, and stretching exercises. In patients where a good effort with these treatments fails to provide adequate relief, some more aggressive treatments may be attempted. These include cortisone injections or extracorporeal shock wave treatments.
The following exercises are commonly prescribed to patients with this condition. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 2 – 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate and advanced exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head until you feel a stretch in the back of your calf, Achilles tendon, plantar fascia or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Resistance Band Calf Strengthening. Begin this exercise with a resistance band around your foot as demonstrated and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 – 20 times provided the exercise is pain free.
