  1. Agreed. I also think it is worth considering the role of tibialis anterior in the development of forefoot supinatus. As we know, when the STJ axis shifts medially, the lever arms between the STJ axis and the insertions of both the tibialis posterior and the tibialis anterior are reduced. Kevin, theorised in his peer reviewed publications that in some instances the lever arm between the insertion of tibialis anterior may be zero, or could result in the insertion of tibialis anterior lying lateral to the axis- what impact might the relationship between the insertion of the tibialis anterior and the STJ axis have on the apparent forefoot to rearfoot alignment with repetitive contraction of this muscle over time, when: a) it has zero lever arm to the STJ axis; b) it has a pronatory lever arm to the STJ axis?
     
  2. I'd also agree, but there is no getting away from the fact that biomechanics is a branch of physics. Some find this "impenetratable" or even, impenetrable. However, for those that take the time to learn basic mechanics, the rewards can be greatly beneficial to all aspects of their podiatric care, not least in diabetic wound care.

    I didn't read the first page of your link, Dennis; I did take a cursory glance at the second page and noted that in the second line of text it states: "... every Doctor of Podiatric Medicine (DPM) has an Evidenced Based Practice Rooted in Biomechanics that includes orthotics..." Can you tell us why these words are capitalised? Was this reviewed prior to publication? Rhetorical questions; never mind. Personally, I prefer a primary source. But if you really want to go off thread... those questions Blinda asked of you regarding "your paper" on nail pathology still remain unanswered as far as I am aware...
