Hi Physiophil,

I am not McKenzie trained - does an anterior derangement result in posterior aspect pain?

Next question is how does the McKenzie Method explain how the anterior derangement leads to a decreased reflex if the spinal nerves are not compromised?

I would like to learn more about how anterior derangement works - I still think a posterior element problem/pain - more likely than the 3% chance of anterior derangement quoted...

By the way, I could only find the busanich 2006 and clare 2004 references. Could you be more specific with your references please? They seem to be reviews that just say that McKenzie helps compared to other treatments but don't say how...

Also, an extension injury is more likely to injure the posterior elements because extension is limited by the Wikipedia reference-linkfacet joints and lamina. It would have to be severe force to cause an anterior derangement with extension. If there was any degeneration in the disc and subsequent loss of disc height, extension and the resultant torque on the anterior disc would also be even less and so less likely to be the reason for pain...

What do you think?
