If anyone is interested there is a lady who is teaching pain science course with the horse in mind. She is very different from rodeo/barrel horse people, but she has a lot of experience in movement science, pain science, game theory and horse experience. I think what she talks about would benefit barrel horses so much. To me it explains why many barrel horses coming back from injury often don't work at all or not as well even though they have healed physically. 
anyway the site is www.pantherflows.com and there is a fee. If anyone does decide to take the course would you let me know? I am and I would love to have a fellow barrel racer to discuss this with.

oops, I didn't even think about this post being allowed since you could construe it as an advertisement, so if it is I apologize and if it needs to be deleted Please let me know and I will delete it. 

Just in case it is allowed, giving it a bump!

Y'all I just watched the first video on pain and it is MIND BLOWING!!! 
PM me if you want to know what is so cool and FREEing about what I am learning. This seems to be explaining so many of our horses problems - resistance, bracing, stiffness, etc. and the best thing is it is SCIENCE based! I am a 58 year old woman who is just so danged excited to be learning such amazing things! 

She has 3 videos you can watch for free to decide if you want to enroll. They are 20 minutes each. 

I'm going to have to check this out!!!
