"I disagree, u can diagnose where a prolapse disc is but i'd rather use the term protrusion as prolapse discs would most likely be sequestered anyway."
hello,
i am not getting what you are intending to say.prolapse can be subclinical.i not the least agree with you comment that disc might be sequestrated mostly.by doing prone knee bend you are checking for femoral nerve involvement.it doesnot help you to localise where the prolapse is,even in case of stenosis,mechanical sensitivity also neurodynamic test will be positive.
