The supination resistance test can be used as a clinical guide to assist the practioner to determine the minimum level of
control (height of orthotic) necessary to sucessfully 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 agressive 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).
- Control tech soft are best for sports, casuals shoes and work boots.
- Control tech flex suits all shoes, excepts women's heels.
- Slim tech suits tighter fitting shoes.
Check the shoes 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.
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. If the patient returns stll 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 can be used.
Soft (Polyurethane)
The soft range is indicated for patients requiring added cushioning or padding.
They are available in two arch heights - moderate and high. Generally, the moderate arch height orthotic is the initial starting
level of support. 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 Sllim tech is indicated.
Full length orthotic sizing:
- The orthotic should be fitted directly into the shoe.
- The orthotic should be tight fitting along the length of the shoe with no curling at the front edge.
- If required, the length of the orthotic can be cut to size.
3/4 length orthotic sizing:
- First fit the orthotic to the patient's foot - the distal edge of the orthotic should finish 5-10 mm behind the bisection of the 1st MPJ.
Within a few days the patient should become accustomed to wearing the orthotic. If any discomfort occurs, have the patient remoce the orthotic
for the remainder of the day, then replace them the following day. This process should continue until the orthotic can be worn comfortable all day.
