Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

Please see our full Terms of Service and Privacy Policy for more information.

Thanks for being a part of the COTH forums!

    +1 to that. I own and wear an Exo vest even though I only do Training level. They're not for everyone, as the sizing is pretty rigid, and heavier than most vests. (Although a P2 + regular vest is within a pound or two of the weight of an Exo.)

    Rotational falls can happen at any level, any height. I just had a near-rotational fall when my horse chested a 2' high log. Unfortunately I was NOT wearing my Exo (it was a last-minute school), but fortunately his feet missed my torso by inches.

        If the Exo vest has a metal frame, couldn't it be crushed into you? Genuine question...I'm not familiar with their technology, but that was my first thought.

          No. Contrary to popular thought and the mis-information that other riders and folks in power spread, magnesium does not act like steel.

          The atomic arrangement of magnesium alloys prevent ductile failure and so it will flex but spring back. If it is flexed to the point of breaking, is shatters. It is a prefect cage alloy (e.g. long used in auto frames etc.).

The impact energy MUST go somewhere, and without rigid fixation of the vest to the rider's hip AND shoulders, the energy will travel axially down the spine.
            So, Reed and wildlifer: I have read several web pages about spinal axial load and burst fractures, but I'm still not entirely sure I understand how this works. Can you explain in fairly simple terms or with pictures?

            From the description, it sounds like she and the horse basically went \ into the ground, yes? and then they went skidding like this __ ? I can kind of follow how that would cause the burst fracture, but I'd love to hear the mechanical breakdown from the experts.

Or is it some combination of the two?

              I ask out of personal curiosity- I just spent the weekend with a bunch of combat medics and military doctors/surgeons all with multiple deployments, and it was interesting to hear about what they saw injury-wise and treatment protocol 5-10 years ago vs. now in military field medicine.

              The injury cause rates are the same as WWII, Viet Nam, but the types of injuries are changing. I can not comment on if there is a 1-to-1 relationship as I don't think the database exists. The one I have seen is the Joint Theater Trauma database. One thing is noted, that the better protection also is the result of better, higher energy methods of taking the body apart.

              In the spine world there is an INCREASE of lumbar and thoracic injuries, mostly due to translocation (being thrown through the air) of a soldier in an explosive event (The Spine Journal - Wartime spine injuries: understanding IEDs).

              There is evidence, but not conclusive, that rigid body armor, while preventing the penetrating wound, causes the body to be rigid in flight, meaning the impact forces, when the person hits the wall, ground, inside of the tank, get transmitted directly into the spine. Ala, a rigid posture as the result of airvest inflation or a very rigid foam standard vest.

                Ditto.

                I have an Exo, and ride in it, and love it.

                    Makes sense. Thanks for the further explanation.

                      True, but I was under the impression that it was no longer on the market. If I am wrong, yay!

                      Reveille, I am NOT a spinal reconstruction expert like Reed, I just have a good working knowledge of physiology, biology, and physics; but basically, if you land, say, on your head at an angle \, then your spine will bend S and some force will be dissipated in different directions by this bending. You might bend in a not so nice way and get fractures, but they would be different kinds of fractures (say pieces of vertebrae breaking off or your neck breaking, which a vest can't stop anyway, or joints torn). Or you might be able to roll and release the energy that way if you are more coordinated than someone like me.

                      If you take away the ability for the spine to bend by holding it rigid, all the force is taken as a direct hit, basically smashing the ends together, like if you took a slinky and smooshed it shut. The energy/force from the impact then has nowhere to go but must get out somehow because it can't just shoot out your @$$ like a lightning bolt (unfortunately, wouldn't that be handy?), so you see vertebrae "burst" from the force of being compressed against each other.

                      If my description is inaccurate, I am sure King Reed shall fix it!

                            They are no longer being manufactured. You can still buy them though; mostly in the UK, but you can google the size chart and then try googling your size. I did this a while ago and found many for sale. Unfortunately, my body shape didn't really work with their v1.0 standard sizes.

                              The general feeling I get is that a lot of people feel as though they've avoided soreness, bruising, and getting banged around by wearing one during a fall. The jury is very much OUT on whether they offer meaningful protection vs. the types of injuries that actually scare me and a lot of other people. I can live with some bruises and bumps and even a broken bone or two. I do not delude myself that this type of equipment is going to protect me from a truly devastating injury, and until that question is answered along with the "bugs" that need working out I don't feel compelled to wear one.
