Role of Neuromobilization in Thoracic Outlet Syndrome

I wanted to know about the evidences based studies and other controlled trials showing the effectiveness of Neuromobilization in the Thoracic Outlet Syndrome. Kindly emphysize and highlight upon that.

I would also be very interested in such a research if it would be valid. I do dought if there is any around which is good. A good entry would be Butler E.A. as a start for a search on the net.
Has anyone a clear idea how to diagnose a TOS? and be a 100% (well a 90 would do) sure it is a TOS.
