Plantar fasciitis is a common and often persistent kind of repetitive strain injury afflicting runners, walkers and hikers, and nearly anyone who stands for a living – cashiers, for instance. It causes mainly foot arch pain and/or heel pain. Morning foot pain is a signature symptom. Plantar fasciitis is not the same thing as heel spurs and flat feet, but they are related and often confused. Most people recover from plantar fasciitis with a little rest, arch support (regular shoe inserts or just comfy shoes), and stretching, but not everyone. Severe cases can stop you in your tracks, undermine your fitness and general health, and drag on for years. This tutorial is mostly for you: the patient with nasty chronic plantar fasciitis that just won’t go away.
Plantar Fasciitis is simply caused by overstretching of the plantar fascia ligament under the foot. So why is the ligament being overstretched? There are different factors, over-use, too much sports, running, walking or standing for long periods (e.g. because of your job) weight gain, our feet are designed to carry a ‘normal’ weight. Any excess weight places great pressure on the bones, nerves, muscles and ligaments in the feet, which sooner or later will have consequences. Even pregnancy (in the last 10 weeks) can cause foot problems! age, as we get older ligaments become tighter & shorter and msucles become weaker; the ideal circumstances for foot problems, unsupportive footwear, ‘floppy’ shoes with no support as well as thongs affect our walking pattern, walking barefoot, especially on hard surfaces like concrete or tiles, low arch and flat feet or over-pronation. An important contributing factor to Plantar Fasciitis is ‘excess pronation’ (or over-pronation). This is a condition whereby the feet roll over, the arches collapse and the foot elongates. This unnatural elongation puts excess strain on the ligaments, muscles and nerves in the foot. When the foot is not properly aligned, the bones unlock and cause the foot to roll inward. With every step taken your foot pronates and elongates, stretching the plantar fascia and causing inflammation and pain at the attachment of the plantar fascia into the heel bone. Re-alignment of the foot should therefore an important part of the treament regime.
The classic sign of plantar fasciitis is that the worst pain occurs with the first few steps in the morning, but not every patient will have this symptom. Patients often notice pain at the beginning of activity that lessens or resolves as they warm up. The pain may also occur with prolonged standing and is sometimes accompanied by stiffness. In more severe cases, the pain will also worsen toward the end of the day.
A physical exam performed in the office along with the diagnostic studies as an x-ray. An MRI may also be required to rule out a stress fracture, or a tear of the plantar fascia. These are conditions that do not normally respond to common plantar fasciitis treatment.
Non Surgical Treatment
Plantar fasciitis is usually controlled with conservative treatment. Following control of the pain and inflammation an orthotic (a custom made shoe insert) will be used to stabilize your foot and prevent a recurrence. Over 98% of the time heel spurs and plantar fasciitis can be controlled by this treatment and surgery can be avoided. The orthotic prevents excess pronation and prevents lengthening of the plantar fascia and continued tearing of the fascia. Usually a slight heel lift and a firm shank in the shoe will also help to reduce the severity of this problem. The office visit will be used for careful examination and review to distinguish plantar fasciitis and plantar heel pain syndrome from other problems, many of which are outlined below. It is important to distinguish between a stress reaction of the calcaneus and plantar fasciitis. A feature of many calcaneal stress fractures is pain on lateral and medial compression of the calcaneus.
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.
You may begin exercising the muscles of your foot right away by gently stretching them as follows. Prone hip extension, Lie on your stomach with your legs straight out behind you. Tighten up your buttocks muscles and lift one leg off the floor about 8 inches. Keep your knee straight. Hold for 5 seconds. Then lower your leg and relax. Do 3 sets of 10. Towel stretch, Sit on a hard surface with one leg stretched out in front of you. Loop a towel around your toes and the ball of your foot and pull the towel toward your body keeping your knee straight. Hold this position for 15 to 30 seconds then relax. Repeat 3 times. When the towel stretch becomes too easy, you may begin doing the standing calf stretch. Standing calf stretch, Facing a wall, put your hands against the wall at about eye level. Keep one leg back with the heel on the floor, and the other leg forward. Turn your back foot slightly inward (as if you were pigeon-toed) as you slowly lean into the wall until you feel a stretch in the back of your calf. Hold for 15 to 30 seconds. Repeat 3 times. Do this exercise several times each day. Sitting plantar fascia stretch, Sit in a chair and cross one foot over your other knee. Grab the base of your toes and pull them back toward your leg until you feel a comfortable stretch. Hold 15 seconds and repeat 3 times. When you can stand comfortably on your injured foot, you can begin standing to stretch the bottom of your foot using the plantar fascia stretch. Achilles stretch, Stand with the ball of one foot on a stair. Reach for the bottom step with your heel until you feel a stretch in the arch of your foot. Hold this position for 15 to 30 seconds and then relax. Repeat 3 times. After you have stretched the bottom muscles of your foot, you can begin strengthening the top muscles of your foot. Frozen can roll, Roll your bare injured foot back and forth from your heel to your mid-arch over a frozen juice can. Repeat for 3 to 5 minutes. This exercise is particularly helpful if done first thing in the morning. Towel pickup, With your heel on the ground, pick up a towel with your toes. Release. Repeat 10 to 20 times. When this gets easy, add more resistance by placing a book or small weight on the towel. Balance and reach exercises, Stand upright next to a chair. This will provide you with balance if needed. Stand on the foot farthest from the chair. Try to raise the arch of your foot while keeping your toes on the floor. Keep your foot in this position and reach forward in front of you with your hand farthest away from the chair, allowing your knee to bend. Repeat this 10 times while maintaining the arch height. This exercise can be made more difficult by reaching farther in front of you. Do 2 sets. Stand in the same position as above. While maintaining your arch height, reach the hand farthest away from the chair across your body toward the chair. The farther you reach, the more challenging the exercise. Do 2 sets of 10. Heel raise, Balance yourself while standing behind a chair or counter. Using the chair to help you, raise your body up onto your toes and hold for 5 seconds. Then slowly lower yourself down without holding onto the chair. Hold onto the chair or counter if you need to. When this exercise becomes less painful, try lowering on one leg only. Repeat 10 times. Do 3 sets of 10. Side-lying leg lift, Lying on your side, tighten the front thigh muscles on your top leg and lift that leg 8 to 10 inches away from the other leg. Keep the leg straight. Do 3 sets of 10.
