Actually, I just realized that the link you provided is not the one I was thinking of. This is it:

The TOS study starts at the bottom of p. 20 of the pdf (p. E143 of the publication).

I like this because it discusses the strengths and weaknesses of all the studies covered.

Here is Jan Dommerholt's page, which links to many of his publications (mostly about trigger points), including the one you posted above.

I have more links on the subject that I've found helpful, if you're interested.

I'm thinking about giving trigger point acupuncture a whirl, now that I'm relatively confident about where my major ones are located.
