Great article about straightness…..
Crookedness has many disadvantages. It leads to an uneven rein contact and uncomfortable gaits. Crooked horses often don’t go on the bit, and they can’t perform certain movements, such as half passes and flying changes, or they can perform them only in one direction. They may also be able to bend only in one direction, but not the other. But the most serious problem is that crookedness can cause lameness in the long run because the horse uses his legs unevenly.
When a horse is crooked, the hind legs don’t follow in the footprints of the front legs, but they are moving slightly off to one side. Some horses get crooked by drifting with their shoulders to one side while the hind legs stay more or less on track. Others seem to keep their hindquarters off to the opposite side while the shoulders stay on the line of travel, similar to the way most dogs run. When you watch them directly from behind, you can see both hind legs and one front leg (looking from the front, you see both front legs and one hind leg).
Either way, the horse will lean onto the front leg that is visible from behind. The extra weight that is placed on that shoulder comes from the diagonal hind leg, which is now “idling” next to the body, instead of participating equally in the work. This also leads to a slight permanent bend in the direction of the idling hind leg, so that the crooked horse is shaped like a banana. The inside of this permanent bend is traditionally referred to as the hollow side. I sometimes call it the concave side. The other side is traditionally referred to as the stiff side. I sometimes call it the convex side.
Consequences
Crookedness creates an uneven weight distribution in the horse’s body: one side of the body has to support a larger percentage of the combined body mass of horse and rider than the other. This has a number of serious consequences:
* The front leg on the stiff/convex side (on the outside of the permanent bend) has to support the largest share of the body mass. This leads to excessive wear and tear. In the short run, it can cause soft tissue damage (especially to the suspensory ligament) when the horse has to perform demanding athletic work. In the long run, it can lead to navicular syndrome or arthritic conditions like ringbone.
* The hind leg on the stiff/convex side tends to take shorter steps because the hind leg on the hollow/concave side doesn’t support the weight long enough for the hind leg on the stiff/convex side to travel far enough forward through the air. It touches down too soon, which cuts the weight bearing/flexing phase of the stride short. This diminishes its range of motion: its upper joints can’t flex enough, because there is not enough time before it has to start extending/pushing again. The rider feels this as stiffness and a sense of hardness under her seat bone on that side.
* The hind legs are the horse’s shock absorption system. When all hind leg joints flex and extend sufficiently, the gait becomes smooth and comfortable to sit, and the horse’s back lifts and transmits the forces of the hind legs from back to front without any blockages. If the upper joints of a hind leg don’t flex enough, on the other hand, the shock of the impact of this leg on the ground is not absorbed properly any more. Then the lower joints suffer because they have to absorb the entire impact of the leg on the ground. Unlike the hip and stifle, the hock and fetlock are not embedded in large, powerful muscles that protect them from damage. That’s why the hock on the stiff/convex side may develop spavin, and the fetlock joint can develop wind puffs.
* If the upper joints of a hind leg don’t flex enough, the horse falls onto the forehand, and the back is not supported. It drops and braces underneath the rider. This can create back problems, such as kissing spines.
* The uneven weight distribution that results from crookedness is a lateral imbalance as well as a longitudinal imbalance. Imbalance always leads to bracing in horses as well as humans, because otherwise the horse (or the rider) would fall down. Chronic crookedness/imbalance leads to chronic bracing.
* Muscles grow or atrophy in accordance with their use. The muscles on the side of the body that has to support a larger share of the body mass will have to work harder than the muscles on the other side. That’s the reason why you can often see larger, bulkier muscles on the shoulder and croup of the stiff/convex side.
* This uneven use of the musculature can lead not only to an uneven development of the left and right side of the body, but it can also cause habitual bracing and muscle blockages, especially in the hips and poll.
* If the back doesn’t lift because it is not supported by both hind legs, it will drop and its muscles will atrophy so that the spine sticks out in more extreme cases. �
Conclusion
�Crookedness leads to an uneven distribution of the weight and an uneven distribution of the work between the left and right side of the horse’s body. Some muscles, joints, and tendons are not participating enough in supporting the weight and moving the body through space, so that other muscles, joints, and tendons have to do more than their fair share of the work. It’s logical that the overused joints, tendons are likely to suffer damage from the excessive wear and tear in the long run. - Of course, there are always horses who stay sound until their 20s, although their riders never did any straightening work with them. Different breeds and different individuals are susceptible to injury to varying degrees. But regardless of breed and individual conformation, the chances of a horse staying sound and being comfortable in his or her work are much greater if we work on diminishing the misalignment of the skeleton and the resulting asymmetrical use of the musculature with gymnastic work as much as possible.
Absolute symmetry is not possible for either the horse or the human, but we can try to diminish the asymmetries in order to avoid excessive wear and tear on the horse’s joints and tendons and to eliminate muscle blockages as much as possible - for the benefit of the horse and the joy of the rider.
