During biomechanical assessments, the degree of abduction and adduction of feet is often neglected and/or not considered.
This is a fundamental examination because a slight difference in bilance (or walking) angle can underline:

a different charge distribution on the two feet, with possible diversity in the heels asset (a straight and a valgus heel, or one more valgus than the other, etc.);

that the feet, to guarantee a comfortable body balance, positionate in an assymetrical way.

This condition underlines a possible eterometry of the lower limbs. So, it will be useful to consider carefully even just the heel asset difference.

to counterbalance an eterometry, you act on the feet angulation and asset, aiming to their equalization (cause-effect).

the foot asset, thinking of an useful correction, has to be evaluated after the eterometry counterbalance!

How to use:
Ask your patient to simply stand inside the platform, and to place both heels against the “heel-support”– remind the patient to keep looking straight ahead and to assume the most comfortable relax position.

Measurements are taken considering the mid-section line passing through the 2 nd /3 rd metatarsus.
