Hi,
Great history - i wish more posts contained as much as you put in. Thanks!
What does "ppn" mean?
Does flexion ease his pain?
I am thinking it is a flexion control problem at L3/4. The theory goes like this...
He is able to flex pain-free. he lacks the ability to find neutral spine and so goes to the end of range of flexion at L3/4 to locate his joint in space. Therefore the joint gets used to flexion and restricted into extension there. Compensatory muscles in the L/S and T/S ES are overworking trying to hold him together.
You can go treat his discs or whatever you want - it doesn't really matter. The bottom line is that you have to stop the repetitive strain on his L/S - That is why the chiro is not working - because it is not primarily a joint stiffness problem but a motor control problem.
What are his Aggs, Eases and PPIVMs like?
Thanks
