Subject: what are long tract signs

All web references to "long tract signs" merely use the term, but never 
define it. It is a neurological medical diagnostic sign. I had a benign 
tumor out a year ago, so I am well past the stage where this is a question 
about a diagnosis. Long Tract Signs are one potential indication of 
advanced stage of the tumor I had. I did NOT have long tract signs. I just 
want to know what this term means.
