I have a weekend show this weekend, and was considering doing a session of the PEMF therapy for my horse. Has anyone done this? Is it worth the money?

I have mine done at least once a month, usually in conjunction with the chiro. I do try to schedule my PEMF 2 days before the barrel race 

Bump

Does it make them sore at all since the description says it's can be a deep tissue massage?

It hasn't mine. I always have my back done as well & I never feel any soreness after. I generally don't feel much difference with my back until the following day. 

IMO it's a waste of money. I don't believe in it nor does my performance vet. 

I recently had a great experience. I have a horse that had scar tissue on his back that was a few years old. He is also super sensitive and tends to hunker his back when being saddled. He was diagnosed with something called myofascial syndrome, which is similar to fibromyalgia in people. Anyways, I did a session on him and the scar tissue went down. When I went to ride him he never once hunkered his back, or pinned his ears which is something he has ALWAYS done for the past five years.

I personally am a huge fan.
