I use a bowen technique lady (my YO and as she uses her for her case studies whilst she is qualifying its free) and if need be follow it up with mctimony
I use a Jane, she specialises in Stress Point Therapy and Myofascial release.
I called Jane in because I had some issues with my mare occasionally dipping her back when getting on board.
Jane works using soft tissue manipulation around stress points to help to relieve any tension or pain.
My mare really enjoyed it and it did resolve the issue. I enjoyed it too, Jane is incredibly knowledgeable and I learnt such a lot about my horse from her.
I use Mctimoney and sport massage therapy for my horses as they respond well to treatment and one mare is very picky on who she has near her and she likes only one back person tried another mctimoney person however she took a dislike to her straight away.
A chiropractor, Dibbs loves it. When I first called her out he had quite a bit of tension in his neck, and had a wonky pelvis, so she needed to come out every 3 months. Now it's more because he enjoys it so much, so she comes out every 6 months.
