I’m not sure why someone sharing their personal experiences and offering observations needs to be responded to with nastiness? Just take it or leave it.
I do agree that many people, whether they’re vets, trainers, average horse owners, etc. can’t always see the different forms of lameness or subtle signs of changes or discomfort in a horses body. Some vets will even admit that is not their strong suit. As for trainers, well, anyone can call themselves a trainer, so that’s a toss up. An experienced, educated, and dedicated professional should have good eyes and a feeling for things, but at the end of the day, they’re still human.
Do I believe that all KS horses are uncomfortable and/or symptomatic? No.
It’s not outlandish to say that there are some common themes with many KS horses though. You can pick up subtle signs in their movement that shows a compensation or adjustment in their way of going. As with many “conditions” keeping them properly fit and paying attention to their body is usually the most beneficial option. This includes fitness from their back and from the ground (posture work, in-hand work, stretches & flexes).
I had a symptomatic KS horse, and his x-rays weren’t as severe as others I’ve seen, but that’s the thing, treat/work with the individual horse. I don’t think that all horses are like him. Some are, some aren’t.
