Hi Chrissy! Thanks so much for your explanations. It is always helpful to talk it through with someone! I’m reviewing the Rancho ROADMAP again, and I have another quick question about part of the long leg algorithm and determining if a DF stop is indicated. I just want to make sure my general understanding of this is on track. It says a DF stop is indicated if PF strength </=4 and/or there is excessive DF/KF or PF/KE. Here is my understanding of why:
-PF weakness: reduced eccentric control of PFors during tibial advancement may cause excessive DF and result in buckling, so a DF stop would block this excessive tibial advancement and prevent buckling.
-Excessive DF: a DF stop would block this excessive tibial advancement and prevent buckling.
-Excessive PF: I would have thought excessive PF would indicate a PF stop, however I’m thinking maybe here excessive PF is a compensation d/t poor stance control (where excessive PF would results in knee hyperextension, as a compensation to prevent buckling). In this line of reasoning, providing the pt with a DF stop would prevent buckling and help them not have to compensate as much.
Just wondering if I’m on the right track with this reasoning, or if I’m missing something!
