Strengthening the core muscles, especially the abdominals, is very important so the muscles support the weight of the barrel and rider and prevent the kissing spine getting worse.
Check out the Equiband system
I have a thoroughbred who has kissing spine. I found out about 6 months ago. He is now in consistent work and on a lunge program once a week and we have just started jumping again, even did a course the other which was amazing and so much fun. He is on a supplement for joints and muscles, corrective shoeing and has a shockwave treatment about once a month. Hope this helps! 🐴🎆 happy riding
My trainers horse has kissing spine. She is an OTTB and is still ridden regularly. She gets the chiropractor out once a month and I believe she is on supplements for joints to help make her a little more flexible which may help take away any back pain. I’m not sure if she does anything else though... hope this helps!
