Thanks Chrissy, I like the explanation of loss of eccentric control of the knee in midstance causing the hyperextension. Makes sense!
As this may be the last chance for correspondence Chrissy, I do want to thank you again for a wonderful experience in getting ready for the NCS. I would have no where felt prepared for it, if not for the detailed and well organized, amazing course you put together!! Regardless of the outcome, I do feel ready to take on and function much more confidently as a Neurologic PT.
