Power in Interruption
September 28, 2018 by Jec Ballou
In the following photo, Roxy demonstrates what I call the power of interruption. This describes the benefit of momentarily altering the horse’s movement patterns for the sake of improving them. Not unlike their human pals, horses generate movement through patterns held in the neuromuscular system. These patterns serve them well, allowing them to move and perform various tasks with utmost efficiency and limited active brain recruitment to move limbs. While indeed efficient, these patterns are not always optimal. For instance, Roxy has a pattern of trailing her hind legs out behind her when she trots rather than swinging them well forward underneath her body as I would prefer.
My task is to help Roxy create new patterns than the ones she knows as comfy and familiar. I would prefer her to adopt a pattern that involves a body posture that is more beneficial to her long-term wellness, or in other words one that sees her carrying more weight on her hind limbs and easing weight OFF her forelimbs. There are number of ways to go about this task, and one of my favorite ones is to interrupt a horse’s existing gait patterns.
As you can see from this photo, the exercise I’m using in this example is fairly simple. It is just a polygon shape formed with poles on the ground. With the horse on a longe line, the handler can move herself all around the polygon, directing the horse across, through, and over the poles in constantly changing ways. The horse never knows where it will be asked to enter/exit the shape. In this way, it delivers all the benefits of schooling over ground poles but eliminates the repetitive and predictable nature of sequential poles set up in single line.
Exercises like this that encourage the horse to adjust her balance, or change her speed and height of stride, briefly interrupts motor patterns. What immediately follows is a chance to develop new patterns. This might mean more awareness of stride trajectory, more flexion in hind limb joints, more precise foot placement. These kinds of exercises open the door to further improvement. They work because the horse is guided to alter his stride with minimal anxiety or tension, given that he is not receiving a lot of input or cues from a rider. The exercises are offering him the input in a very natural, easy way.
Admittedly, there is plenty of time during a horse’s schooling when we want our work to be predictable for him so he gains confidence and clarity in our expectations. When changing his physical body and gaits, though, it can be helpful to introduce a little well-timed interruption. The key is to use just a little (not so much to frustrate the horse), and that any chosen exercise has relevance to an existing pattern you hope to change. In other words, we’re not seeking to interrupt his patterns just for the sake of adding randomness or variety to his routines. The exercises need to support your specific goal in each session.
