The book 'Back Mechanic' guides individuals through self-assessment by creating a table of pain-inducing and pain-relieving activities, and performing physical tests to identify pain subcategories.

“well short of that I wrote back mechanic now it's not on the internet and the reason is they have to have some background understanding of how their back works and then go through a series of self tests that's what the book does the first thing is it just says draw a table what are activities that cause you pain what are activities that either take your pain away or are neutral write them all out”
