WHAT IS PLANTAR FASCIITIS?
The plantar facscia itself is a thick, fibrous band of connective tissue that runs from the heel to the toes along the bottom of the foot. This tissue has the purpose of forming the archest of the foot as well as functioning as a shock-absorber.
Plantar fasciitis is one of the most common causes of heel pain caused by a chronic overload of the plantar fascia. Although the name suggests the condition is due to inflammation of the plantar fascia (‘itis' indicating inflammation), evidence now suggests the underlying process is more common than not degenerative rather than inflammatory. For this reason, you may see it referred to as ‘plantar fasciosis’

WHAT CAUSES PLANTAR FASCIITIS?
Plantar fasciitis typically occurs as a result of the plantar fascia being subjected to repetitive strain from long periods of standing or running, commonly with unsupportive footwear or barefoot. This commonly leads to degeneration and increased thickening of the tissue contributing to heel pain.
Other risk factors include:
HOW TO TREAT PLANTAR FASCIITIS USING PHYSIOTHERAPY
Recent evidence suggests loading the calf and plantar fascia through heel drops can improve pain and activity levels.
Strengthening consists of heel-drops off a step with the toes in extension using a towel. This encourages load through the plantar fascia which may improve the structure of the tissue as well as improve calf strength throughout ankle range.
Placing the affected foot on the edge of a step with a towel underneath the toes to encourage full toe extension. Holding on to a wall or other stable surface is encouraged for balance.
The 3 main movements of the exercise include:
Movement 1: Raising the heel above the level of the step in a slow, controlled movement taking 3 seconds to come all the way up
Hold the raised position at the top for 2 seconds
Slowly drop heel back down below step-level taking another 3 seconds.
Continue this exercise for 12 repetitions ensuring correct form. If 12 repetitions cannot be achieved, the exercise can be modified by using both feet for more support.
This exercise can be progressed by adding weight through a backpack until the maximum amount of weight that can be lifted 12 times correctly.
Weeks 1-2: 3 sets of 12 repetitions every second day for 2 weeks.
Weeks 2-6: 4 sets of 10 repetitions every second day for 4 weeks
Weeks 6+ : 5 sets of 8 repetitions every second day
Evidence suggests manually stretching the plantar fascia can contribute to improved pain and activity levels in the long-term.
Stretching consists of crossing the affected foot on the opposite knee and pulling back on the toes towards the shin. The other hand can be used to massage through any points of increased tension whilst the stretch is applied.
The stretch can be held for 10 seconds for 10 repetitions, 3 times per day.
Another treatment method for plantar fasciitis is ‘low-Dye’ taping. Taping can be particularly effective for short-term management to offload strain on the plantar fascia contributing to decreased pain. This makes taping an option as an adjunct treatment to more long-term management strategies including strengthening and stretching.
