WHY ARE DRAW REINS A BAD IDEA?
I could write a very long, technical explanation, but it’s really quite simple. Draw reins place the horse’s mouth at the fulcrum of a lever, one end of which is fixed (the girth), the other end is totally reliant on the feel, or lack of, in the rider’s hands. It is very, VERY easy to over-shorten them.
• They shorten and compress the neck
• They force the horse to close the angle in his gullet, crushing the larynx, parotid and restricting the hyoid apparatus. This also creates hyperflexion in the upper neck, damaging joints and ligaments.
• Compression at the base of the neck will cause most horse to drop through their chest and withers to try to fit the vertebrae into the smaller area they have been given. Rather than a regular, smooth curve at the base of the neck, you then have an ’S’ bend. This drives more weight through the horse’s front legs, making them ‘on the forehand’. Ironic, given that one of the supposed benefits of draw reins is to create lightness in the forehand (actually, they just encourage the horse to sit behind the contact).
• Dropping through the base of the neck will create hollowness under the saddle.
• With all that compression going on in front, any energy created by the hind limbs simply cannot be transmitted forward. There will be a ‘log jam’ somewhere in the middle, probably right under the rider.
• Often, because of this, horses will simply trail their hind limbs.
• A study by Bystrom, et al showed that head and neck angles were significantly decreased, and limb kinematics were affected by the use of draw reins. Roepstorff, et al, found that the use of draw reins influenced ground reaction forces at trot.
We are all familiar with the concept that the horse’s hind end is his ‘engine’. Pulling the front end in and forcing an outline effectively stalls that engine, and creates a chain of damaging load patterns, which will ultimately lead to injury.
Some would argue that only skilled riders should use draw reins. I would argue that really skilled riders have no use for them. If the horse is putting his head up, strong or leaning (already on the forehand, fyi), it is the rider’s responsibility to work out why. This could be due to discomfort, lack of training, or a combination of the two. The horse needs to be shown how to better carry himself through improved hindlimb engagement and posture, which will, in turn, lighten the forehand and allow a soft, lengthened neck to a light, elastic contact.
There are no short cuts to helping the horse find balance under the rider.
The picture illustrates how the horse will sit behind the contact, is compressed through the gullet and over flexed in the upper neck. You can clearly see that the horse’s face is behind the vertical and there is tension in the neck muscles. There is not even any contact on either sets of reins – it is common for horses to do this to avoid uncomfortable mouth pressure, and too often gets confused for being ‘light in the contact’.
You might think it would be a physiotherapist's dream, fixing problems caused by improper use of gadgets - but I'd much rather identify why the horse is having difficulty balancing himself, correct any musculoskeletal imbalances, and help the rider help the horse in a sustainable way.
