I currently ride a horse who has kissing spine and though his is definitely something that needs attention, it isn't the most severe case. Nothing bothers him except dismounting so I try to pay attention to make sure things don't bother him and have to dismount in a particular way. I also do a lot of work to build his topline and get him to use himself properly which helps. I also try to have a very soft seat. At the end of the day though I think it really depends on the unique case.
I know a tb last summer that got diagnosed with kissing spine and they gave him back injections and had him on a very consistent training program riding him to really strengthen his core and he did great after that :-)
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.

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!
