Plantar fasciitis often occurs in middle-age. It also occurs in people who spend long hours standing on their feet at work, like athletes or soldiers. It can happen in one foot or both feet. It is common in sports like long distance running, dancing etc. Athletes who overpronate (rolling in or flattening feet) are especially at risk as the biomechanics of their feet place more stress to the band. Plantar fasciitis can take a long time to heal. Six months is the average time reported in medical research. There are some who will get cured after a few weeks and for others it will take more than a year. It can also become a chronic condition in which case some sort of treatment will always be needed to prevent the pain from coming back. As sooner as the condition is treated chances are it will not get chronic or in other words if you treat plantar fasciitis sooner you will get cured faster.
Inappropriate footwear is the No. 1 cause of plantar fasciosis. Footwear that possesses toe spring and a tapered toe box holds your big toe in an adducted and extended position. In this position, your abductor hallucis muscle-the muscle responsible for moving your big toe away from your foot’s midline-pulls on a foot structure called the flexor retinaculum and may restrict blood flow through your posterior tibial artery, the vessel that carries blood to the bottom of your foot. Tissues in the sole of your feet begin to degenerate as blood supply to this area is decreased. Other recognized causes of or contributors to this health problem include the following, calf muscle shortening, plantar fascia contracture, Obesity, rheumatoid arthritis, reactive arthritis, Psoriatic arthritis, Corticosteroid injections.
The major complaint of those with plantar fasciitis is pain and stiffness in the bottom of the heel. This develops gradually over time. It usually affects just one foot, but can affect both feet. Some people describe the pain as dull, while others experience a sharp pain, and some feel a burning or ache on the bottom of the foot extending outward from the heel. The pain is usually worse in the morning when you take your first steps out of bed, or if you’ve been sitting or lying down for a while. Climbing stairs can be very difficult due to the heel stiffness. After prolonged activity, the pain can flare-up due to increased inflammation. Pain is not usually felt during the activity, but rather just after stopping.
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
A number of conservative measures can help take stress off the plantar fascia and encourage healing, including Icing, Taping the arch and bottom of the foot, Stretching, especially the calf, Avoiding walking with bare feet, especially on hard surfaces, Wearing orthotics or arch supports, Taking over-the-counter anti-inflammatories. If these methods fail, we generally try one of two things, A cortisone injection can help reduce swelling. Often a single injection will do the trick, but occasionally a second injection may be needed. Alternatively, we can try extracorporeal pulse activation therapy, or EPAT. This method uses sound waves to penetrate to the plantar fascia and stimulate the body’s healing response. We typically do one treatment a week for three weeks, with complete healing taking between nine to 12 weeks.
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
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.
