I am currently in my final year of study to become a qualified physio. I need someone to direct me as to which literature is best re-pain gate mechanism (neuro physiology) and how the process works. Is any one aware of any good detailed books/literature? I have managed to check out "Grieve's Modern Manual Therapy: The Vertebral Column" and has a very good chapter dedicated to it. Any other books you have found useful which I may have missed out?
