Where did Root tell us how to arrive at a orthotic prescription?

    All,
    I've got "neutral casting techniques" and "vol.2", but where did Root describe how to arrive at posting angles for foot orthoses based on his biomechanical assessment? Is it in Vol. 1? Philps gives a rationale, did Root? I can't remember?

    How did he say we should decide upon the rearfoot posting angle, and where?

    I don't remember seeing this from Root. At CCPM in the early 80's Biomechanics II, IV, and V was taught by John Weed. In his lecture sylabus he descibed how to "balance" the cast. He took nearly a whole semester to say if the heel can evert to perpendicular balance to perpendicular. There was more than that, but He described, for each foot type it should be balanced and there were few exceptions. I still have my sylablus in the binder that I used as student. An interesting historical reference.

    I have the audio tapes from an early Root seminar .... I sure it was in there; but that is not much use.
     
  4. I don't believe Mert Root ever wrote about this topic in any of his books. As Eric stated, we got most of this information on rearfoot posting application and theory from John Weed when he was teaching us. The "standard" rearfoot post motion of 4 degrees was based on the idea that the calcaneus should evert 4 degrees during contact phase normally. You can quote me on that as being personal communication with John Weed, DPM, from 1980, if you like.:drinks

    I was looking through John Weed's sylabus a few years back and recall seein a note I made in the margin in class. He described pushing upward on the foot to see how easily it supinated. If it was difficult to supinate he added more antipronation features. I had no idea what he meant at the time, but it was obviously a precurser to Kevin's STJ axis palpation.

  6. John Weed is who I got the idea from, but John only pushed up on the heel, not the forefoot. In fact, I still remember the discussion I had with him standing outside the MO lab of CCPM one day during my Biomechanics Fellowship in 1984. At that time, I had no idea as to where his idea would lead me.....
