"Pre-Rehabilitation"

This article about Alex Rodriguez's missing the first half of the 2013 Baseball season due to injury includes the term "pre-rehabilitation", which has got to be just about the most retarded 'word' ever.

I tried to figure out via google if that monstrosity is a real word, and the main thing I found out is that Clemson University offers a degree in "Prerehabilitation Sciences".

I know, I know: I am a grammar Nazi. Guilty as charged.
