Supination Resistance Test

This Supination Resistance Test assists to determine the amount of support required by an orthotic. The measurement is subjective and assigned an arbitrary score – high, moderate or low.

Generally, the higher the force necessary to invert the foot (high Supination Resistance Test), the greater the amount of rearfoot wedging and medial arch height required.

Orthotic Implications

A high supination resistance score indicates the use of a HIGH arch orthotic.
A moderate supination resistance score indicates the use of a MODERATE arch orthotic.
A low supination resistance score indicates the use of a LOW arch orthotic.


This is a subjective test, which requires practice to gain experience for the different levels of force needed to supinate a foot. The patient is asked to stand in their normal angle and base of gait, two fingers are placed under the talonavicular joint and the amount of force that is needed to supinate the foot is estimated.

About Interpod’s Biomechanical Tests

Interpod utilises the most current biomechanical tests to aid with orthotic prescription. The following relevant biomechanical tests will help practitioners maximise patient outcomes.

The purpose of a biomechanical test is to determine if patient symptoms are mechanical in nature or whether they are caused by other factors such as illness. The results of a biomechanical test can be used to highlight the pathomechanics of patient symptoms. In addition, they can be used to determine the most appropriate orthotic and possible orthotic additions if required.
