Are Root Biomechanics Dying?

Discussion in 'Biomechanics, Sports and Foot orthoses' started by Kevin Kirby, Apr 2, 2009.


  1. Jeff:

    The phrase "holding the foot in STJ neutral position" was only used to describe the effect of Root orthoses in standing. The phrase "functioning around STJ neutral position" was used more to describe the effect of Root orthoses during gait. Sorry, for the misunderstanding.

    However, it was taught to us as podiatry students that we casted the foot for orthoses in the subtalar joint neutral position since this rotational position was the ideal position that we wanted the foot to function in. Are you saying that this is not something that Drs. Root, Weed, Orien and their CCPM biomechanics faculty taught to hundreds, if not thousands of podiatry students and podiatrists over a few decades?

    There have been more studies documenting the effectiveness of lateral wedges. The laws of engineering support the use of a lateral wedge with genu varum and a medial heel wedge with genu valgum. This will decrease bending moment on the knee.

    Just because you are succesful, does not mean that you know why you are successful. For example, "stabilizing the calcaneus" is essentially a meaningless term. How do you measure how well a calcaneus is stabilized.

    I've read a lot of Root, Orien and Weed and "mimicing the action of the cuboid" is a new one for me. Did Root et al actually use this term? How do you mimic the action of the cuboid? How does this stabilize the calcaneus. If a paradigm uses terms like stabilizing the calcaneus, then it should discarded or amended.


    One of the advances of Root Theory is that it introduced and emphasized a terminology that we still use. This terminology helps pratcitioners discuss feet. Obviously, that terminology was not sufficient for you to get what you want from a lab.


    His work has inspired me to go beyond it and to study engineering. I've found it better to use engineering principles applied to anatomical structures rather than use nebulous concepts like stabilize a bone. We can still make a difference after we've moved on from "locked midtarsal joints". Anything that will replace Root theory will have to explain the success of the Root paradigm. I believe the tissue stress aproach can do that.

    Cheers,

  3. Alex, your nonsensical rant above is just that. Control?

    New Fast Automatic Daffodils: "Working For Him":
    "One of the controllers had 50 runners working for him.
    One of the controllers had 50 runners,
    one of the controllers had 50 runners working for him.

    Working for him, working for him.

    One of the runners drank 50 liters a day.
    One of the runners drank 50 liters a day,
    they're working for him.

    They're working for him, working for him.

    They took their test in the control zone,
    accept the best in the control zone,
    behind the rest in the control zone,
    no success in the control zone,
    your warning now, you're on your own,
    your warning now, you're on your own."

    dear robert
    sorry it took me so long to get to this post but be rest assured there is always some one looking around. frankly speaking you deserve an oscar for this ingenious analogue bravo bravo! who are we kidding?:bang:disregarding someone's efforts who is supposedly one of our pioneers is so sad and guess what we use newtonian in the process ha ha ha. all these new models as you said will always reflect on root's theorem,:deadhorse:
