Do you think it helped? - Yes
Did you use vet or other provider’s laser? - Massage therapist & barn mate
If you bought/borrowed one, brand name? - You can rent a unit from respondsystems.com
An old barn mate bought a unit because her horse had some major issues. Several of us had her work on our horses and they were quite vocal about where they wanted to be treated. My horse’s massage therapist, who is used by a few BNT and is now able to work at FEI events, uses it on the muscles that are extremely tight to help the horse feel better quicker.
If I had the money, I would walking around with a laser unit & PEMF unit. But, one can only dream.
