Interpod prescription guidelines

Step 01. determine level of support

The supination resistance test can be used as a clinical guide to assist the practitioner to determine the minimum level of control (height of orthotic) necessary to successfully relieve a patient’s symptoms.

With the patient weight bearing, using two fingers under the talonavicular joint, pulling upward- attempt to supinate or invert the foot. Generally a foot that is easy to supinate (score 1-2) requires a less aggressive orthotic ( low arch height). Patients which are more difficult to supinate (scores 2-4) require a moderate amount of support while those that are very difficult to supinate require more aggressive orthotic treatment (high arch).

Interpod range of orthoses are unique in that they are available in three arch heights (levels of support) and two different material types (soft and flex).

Step 02. consider shoe type

Flex	Soft	Slimtech

*Check the shoe into which you are fitting the orthotic. Badly worn shoes must be replaced. Thick linings inside the shoe may need to be removed to allow for space.

Step 03. orthotic type - flex or soft?

3a. Flex (Polypropolene)

Flex orthoses are very durable. They are available in three arch heights - low, moderate and high. Generally, the moderate arch height orthotic is the initial starting level of support for the flex. If the patient returns still symptomatic and without any undue foot or arch discomfort then the High Arch orthotic would be indicated. For patients with a low supination resistance score, or tight footwear, then the low arch orthotic is indicated.

3b. Soft (Polyurethane)

The soft range is indicated for patients requiring added cushioning or padding. The full length soft is available in three arch heights - low, moderate and high. Generally, the low arch height orthotic is the initial starting level of support for the full length soft. If the patient returns still symptomatic and without any undue discomfort then the high arch orthotic would be indicated.

For women’s dress shoes or tight fitting shoes the slim tech is indicated.

Step 04. fitting to the patient

Full length orthotic sizing:

the orthotic should be fitted directly into the shoe
if required, the length of the orthotic can be cut to size.

3/4 length orthotic sizing:

first fit the orthotic to the patients foot- the distal edge of the orthotic should finish 5-10 mm behind the bisection of the 1st MPJ.

Step 05. patient advice

Within a few days the patient should become accustomed to wearing the new orthotic. If any discomfort occurs, have the patient remove the orthotic for the remainder of the day, then replace them the following day. This process should continue until the orthotic can be worn comfortably all day.
