Plantar Fasciitis – How to get rid of it if you don’t want surgery

If you have ever had the misfortune to have plantar fasciitis you will know that it can be a pervasive problem in that it affects every activity that involves standing or walking.  Around 80% of all cases will resolve within one year (even without treatment) but 10% of people will endure the condition for their lifetime (1). Most people have heard of it and many people will have a story about how hard it was to get rid of it, but what exactly happens to the foot when you get plantar fasciitis, and what is the best way to get rid of it?  Surgery can be very effective as a last resort, but what else can you try before you get to that stage?

Plantar fasciitis is defined as being ‘a condition in which there is persistent pain associated with chronic degenerative and reparative processes affecting the origin of the plantar fascia and surrounding peri-fascial surfaces’ (1).  Sufferers tend to complain of pain on the sole of the foot, usually from the heel and then inwards towards the arch of the foot, the pain is commonly worse on standing first thing in the morning, the pain may lessen as more steps are taken but will reoccur as the activity is prolonged, leading to a limited ability to perform activity (2).   You are more likely to get plantar fasciitis if you;

  • Are aged 40-60.
  • Are female, women are slightly more likely to get it than men.
  • Are overweight.
  • If you stand for long periods on hard surfaces.
  • If you are a runner, or play high impact sports on a hard surface such as basketball (3).

The tissue affected is the plantar fascia, this tough piece of connective tissue runs from the heel bone to the base of the toes and provides shock absorption and when loaded provides a stiffening mechanism that supports the arch of the foot. It is incredibly strong and is thought to be weakest where it inserts into the heel (4).   When you walk, at the ‘push off’ phase of the stride the toes have to extend, this generates a pull on the plantar fascia resulting in a bracing of the bones of the foot (see image to the left), resulting in reinforcing the mechanical stability of the foot and possibly resulting conserving energy lost by a recoil effect (5).  

When the plantar fascia is mechanically overloaded ‘microtears’ are caused where it joins the heel, producing pain and changes in the tendon that might result in the problem becoming chronic (6). 

So if you have this pain, how do you get rid of it?  In some cases the cause of the problem will be obvious, usually the sufferer has done more activity than they are used to, either for a longer duration or more frequently, resulting in damage to the plantar fascia.  Resting and reducing the load on the fascia through reducing the intensity, duration and frequency of the activity will often result in a reduction in symptoms.  In the short term applying ice to the area of pain and taking anti-inflammatories will help control the pain while recovering (7).

For those people who find that they do not recover with rest, there are several possible avenues of investigation that may help them find a solution to their pain. 

The first plan of action should be to look at the reasons why the problem occurred in the first place, recent studies have found that sufferers of plantar fasciitis were more likely to have;

  • Reduced mobility in the ankle and big toe (8).
  • Have a higher body mass index (8).
  • Reduced calf strength (8).
  • Less flexible hamstrings (8).
  • Have recently (if they run) changed their training pace or increased their mileage, or have tried to change to a different foot strike pattern (8, 9).
  • Have reduced strength in muscles that flex to toes and turn the ankle out (10).

Careful assessment from an expert and advice on how to correct contributing factors such as these may provide a basis for an effective treatment programme for sufferers of plantar fascia.

Other interventions that have some evidence to suggest they may help include;

  • Plantar fascia specific stretches, usually ankle stretches that also extend the toes (11).
  • Progressive loading of the plantar fascia over a course of 12 weeks, usually a calf raise with the toes extended (12).
  • Recent reviews have shown that shoe inserts (orthotics) that raise the heel up and decrease the tension on the plantar fascia may reduce the pain (13). It is also not important if the inserts are custom made of off the shelf, both are effective (14).

If you don’t call injections surgery then recently there was a study that provided strong evidence that carefully prescribed exercise, combined with a course of corticosteroid injections, and activity management over three months produced excellent short and long term results indicating this may be the most effective non-surgical care option (15).

In our experience as osteopaths to improve the symptoms of plantar fasciitis an accurate assessment is crucial, this should include a thorough exercise history, strength tests and joint assessments to determine why the tissues of the plantar fascia are being placed under excessive strain.
