I can thoroughly recall reading through a very informative and rather lengthy thread (which as best I can remember was was posted maybe around Christmas 2012)? Someone posed the question as to what the specific goal of, I believe, using overreach boots is--For example, which structures are meant to be protected/what sort of strike injury and where is the boot capable of preventing?
That thread also got into many other issues as I recall, such as:
1) which the best sort of boot and other protective leg devices to be worn by the horse, and 2) which boot/wrap offers the most protection to the horse, and 3) from what sort of injuries...
Again, the different boot types discussed in the thread included overreach boots, polo wraps, and the wrap-around sort-maybe called "Equinoclast" or something similar?...Generally speaking, folks seemed interested in which type of device best mimics the kind of supportive devices worn by human atheletes meaning to best support previously strained/weakened knee/ankle/elbow areas, which are worth buying/using, and which are "crap", and not worth the cloth they're made out of?
Perhaps the thread was called something like "What exactly is the purpose of overreach boots?", and from that answer, the thread took off in many interesting and informative directions. I did look for that specific thread for a bit before adding another similar one with this, but was unable to find it. I'd certainly be happy to have a mod who knows where it is and what I'm referring to, link this thread up with it, if it was recent enough! However, what I am putting up may be asking an overall different question/serve a somewhatdifferent purpose when we get to the You Tube video...
As I stated at the start of the post, I am putting up a link to a You Tube video I happened across, which displays what I can only assume is an experiment of sorts, wherein a horse's leg (only the leg--with all underlying structures--tendons, bones, etc...visible, so if you are at all squeamish/uncomfortable with such things, PLEASE DO NOT WATCH THIS!!) is in some sort of a contraption devised to mimic the same sort of pressure it would be under while the horse is trotting, and then galloping, and the subsequent possible injuries which can befall the horse if the leg is NOT protected and it is "clipped" by a back leg (they use a scalpel to mimic this in the video, but I know hooves at high speed are extremely sharp, so I think this could be an acurate representation, though am not certain).
The video depicts three "people" (no description is available as to their credentials, or even their names.) There is no description of whether this "experiment" was a part of a veterinary/other school project, a racetrack expose of some sort--I kind of get the feeling that is the gist, but again it is not stated whatsoever. Perhaps this is just a group of twenty-somethings with an extra cadaver-horse-leg lying around doing macabre displays with it ...I CERTAINLY HOPE it is NOT the latter of the choices...
The video seems to have an overall legit purpose, and the two men at least of the three total people, seem fairly knowledgable about some of the more basic anatomical structures and what not, but I feel strongtly that the experiment would have been MUCH more informative if they had A) provided their credentials, B)given a brief write-up as to whom they were affiliated with and the hypothesis they were trying to prove or disprove with this experiment.
They vaguely mention such, of course, and do go through the stages of showing that clearly the tendons, ligaments, and bony structures are under great pressure and are specifically and miraculously designed for the purposes which a horse uses effeciently, but it just would have been nice to see the purpose of what they were doing and possibly a link to a published article.
I do remember that overall, the information which was most prevalent in the thread about this subject referred to prior, was provided mainly by one poster in particular; I cannot recall whom, thus, I do apologize. This member had a significant amount of data theorizing that almost no boot could be protective enough to truly prevent injury and not cause significant secondary problems due to a multitude of factors.
I am well aware that many of you here on HF are quite well educated regarding such issues, thus, I believe at least you may get something out of this video, and perhaps be able to come back with some opinions regarding the "experiement", and whether you feel it was in any manner well-done, or totally worthless. I'm very interested to hear your opinions. Thanks for reading through this extremely lengthy intro!
