This is a quick little video that might be helpful to those of you that want to see how to angle a RF (rearfoot) post.
Also, there are those of you that want to adjust the angle on a RF post on an existing orthotic while your patient waits.
As you see, the camera man is facing me while looking directly over the machine to get a clear view.
The first thing to notice:
4 seconds in: See how I tilt the orthotic slightly.
A little goes a long way here. It is a very slight tilt that you see. Tilting the distal, medial corner of the orthotic at the 1st met lower, or closer to your body will add a varus angle to the orthotic.
Tilting the opposite way will add a valgus angle. If you hold the distal edge parallel to the wheel, you will grind a flat angle into the heel.
27 seconds in: Notice how the sound changes when I start to contact the plastic….
When you are grinding, it is helpful to listen for the change in sound as the wheel starts to hit the plastic.
This is helpful because you will not have a sense of how much to grind off. When you hear the change in sound, it will help you to know that you are just about there!
