What an interesting question! Congrats on your fine MEDLINE skills.
You're doing everything right. (Explode, Focus, Limit, etc. etc.)

Just for fun, I went to PSYCINFO with your topic, and played around
with something like this:

((magnetic adj field$1) or magnetism or subj electrical stimulation)
and (treatment$ or therap$ or outcome$ or pain or headache$) and not
subj ELECTROCONVULSIVE SHOCK THERAPY

... and I got thousands of article, so I'd have to figure out more
"limiting" things to do with that, but it was fun...
