My answer would be yes, it can alleviate these problems but
a lot depends on the experience and type of training a chiropractor has!
Personally I do not like McTimony trained chiropractors. I think that you might as well spit into a force 9 gale for the good they do.
I have also had more harm than good done by poor chiropractors.
On the other hand, a good chiro is often better than the vet!
Look at the horse as a car in that it has four corners. You can drive a car with the tracking out but the steering and brakes do not work as well and the tyres wear out unevenly.
It is the same with horses and humans, if a part of the body is misaligned then the muscles will either tighten or loosen and this can happen where one side loosens and the other tightens. In turn this causes other reactions further along the body, and the wear and tear is uneven - often causing arthritic changes.
When realigned the wear goes away.
I do not believe in such a thing as a cold backed horse. Yes, a horse will shrink away from the pressure of the saddle but this is not because the back id 'cold' it is from the tension in the muscles going across the horse's back from misalignment in the shoulder and the diagonal hind quarter. Get those squared and the tension immediately disappears. It is very very rare for a horse to actually move a spinal disc, When these are 'out' it is generally caused by a chiropractor.
This is a picture of a horse that is misaligned in his pelvis you can see how uneven he is. He was showing signs of stiffness in his hocks and had had injections. http://i154.photobucket.com/albums/s...ter49/hips.jpg
By reading through Applied Kinnesiology (AK) it was determined that this needed straightening by a high lifting,
Unusually, this horse was wrong in his left shoulder as well as his left hind - 90% it is diagonal. This was also straightened.
Finally, the muscle memory was altered so that they did not pull the misalignment back from where it should be. http://i154.photobucket.com/albums/s...indmuscles.jpg
There are several exercises that you can do to see if the horse is square or not. If anyone wants them PM me and I will send them to you. I have out another horse (chestnut) rather than the bay, having a high lift as it is a better picture
