actually, you wrote in your first post "M.R.I which was taken 8 months back shows L5-s1,L3-L4 posterion disc prolapse with pressure on thecal sac"........
but i read through some of your other post in the ortho forum... and i'm still confused...
you're using the term "neurologic claudication" to mean a limping due to neurologic complications, right? i see that extension would be bad for a stenosis patient, but i thought we were dealing with a patient with posterior disc prolapse... you should do extension exercises for posterior disc protrusion, correct? but not if there's stensosis involved.........
hmmm.... maybe this is why i'm a stroke junky and not an ortho kid...
