Many often ask me if I know if a patient will benefit from orthotic therapy – which are shoe inserts designed to help alleviate pain or correct biomechanics that are causing discomfort.

I always stress that orthotics cannot always fix a problem alone and is not a cure but a practitioners tool to use in treatment, but you can achieve great results when you use Dr Abbie Clinics Orthotics as part of your treatment, if required.

During a patient’s initial consultation they will generally outline a point of pain (POP) and will be looking to gain quick, if not immediate relief. As practitioners we should be sensitive to the pain our patients suffer, however in my clinic I initially treat the P.O.P whilst at the same time endeavouring to identify the root cause which has triggered the symptomatic pain (in non trauma cases only).

Let’s look at the case of a Plantar Fasciitis (heel spur syndrome) sufferer.

In this situation excessive Subtalar joint pronation lowers the arch structure causing the foot to elongate and traction forces are placed on the Plantar Fascia. This all results in inflammation of the plantar calcaneal attachments (Warren, 1990; Kibler et al, 1991).

The practitioner must first accurately identify where the pain is felt by the patient – medial heel pain, lateral heel pain or central heel pain. The P.O.P is very important to identify as this will help determine the best form of treatment.

There are three aponeurosis under the foot – medial, centre and lateral attachments to the calcaneus. Thus it is critical to identify the point of pain, as it will greatly assist in the diagnostic process and subsequent treatment.


Medial Heel Pain – is associated with excessive pronation – more than the 4˚ the body allows. This causes the medial plantar fascia to elongate and tear away from the calcaneal attachment causing inflammation and pain.

Central Heel Pain – is associated with high lateral heel strike in gait to mid foot collapse, and pronation at mid stance of gait, together with a forefoot valgus deformity. When the foot lands laterally the ground, reaction forces propel the foot into pronation as it enters mid stance, causing middle or central plantar fascia tearing to occur, by creating a ‘pivot point of tear effect’.

Lateral Heel Pain – is associated with a Pes Cavus foot structure or a high forefoot valgus which causes the lateral plantar fascia to strain from the attachment. A fixed plantar flexed 1st ray can also cause lateral heel pain.

All the above will effect either lateral heel pain, medial heel pain or centre heel pain.


  1. Check if the patient is pronating or supinating. Look at the amount of pronation by correcting the feet to neutral (Neutral Calcaneal Stance Position), then allowing the patient to relax (Resting Calcaneal Stance Position). This will identify the total pronation factor.
  2. Check the patient’s weight, so you will know which Dr Abbie Clinics Orthotic density will be most suitable, i.e. supporting the patients arch without collapsing under their body weight.
  3. Identify if there is a forefoot valgus. If a forefoot deformity exists, attach the appropriate size forefoot addition to the orthotic prior to heat moulding. Then proceed to heat mould the ortho

  4. When fitting orthotics always check if there is a structural leg length difference. If a leg length difference is detected the fitting of orthotics will remedy any long leg compensation. If the patient has a short leg add a heel lift (i.e. 4mm) and build up gradually to the required height.
  5. Check the patient for a tight plantar fascia (See Figure 4 below) as this may cause orthotic compliance problems and irritation in the patients’ arch.


If the patient does exhibit a tight plantar fascia, a plantar fascial groove will need to be made into the arch of the orthotic, after the heat moulding process.

Post-Compliance Issues

If after the wearing-in period the patient complains of pain under the arch caused by the orthotics, check the following:

  1. Is the orthotic sufficiently controlling the pronation?
  2. Is the patient’s Neutral Calcaneal Stance Position greater than the 5˚ built into the orthotics? If this is the case:

a. Check the density guide  and upgrade the patient to a more supportive controlling device, eg. change from an Dr Abbie Clinics Mid density Blue orthotic to a Firm Green orthotic.

b. If the density is correct but the device is not controlling the pronation, increase the inversion angle by adding a Rearfoot Varus Addition to the existing orthotic.

c. If the patient’s NCSP measures higher than the 5˚ rearfoot varus angle built into each Dr Abbie Clinics Orthotic follow step b. and add the required Rearfoot Varus Addition and re-mould the orthotic.

Additional Treatments

  • Low Dye Strapping: to assist or mimic an orthotic
  • R.I.C.E
  • Foot Mobilisation
  • Deep Tissue Msssage – to break down fibrous tissue
  • Differential Diagnosis
  • Entrapement of the medial calcaneal branch of the tibial nerve.
  • Tarsal Tunnel Syndrome
