Tissue stress theory: Just a variation on root theory?
from Podiatry Today
The following is a rebuttal to your cover feature, "Has Tissue Stress Theory Supplanted Root Theory?," by Kevin Kirby, DPM, in the April 2015 issue. The Root paradigm has existed for over 35 years and has brought order to the field of lower extremity biomechanics. Dr. Kirby's methods will not build a better functional orthotic device but just another fancy arch support. Dr. Kirby has the tail wagging the dog. His theories are subservient to the Root paradigm. In other words, they are built on the bones (pun intended) of Root theory. Soft tissues are not the usual cause of foot deformity but the result of being traumatized by forces greater than soft tissue can or was intended to resist.
