Let’s talk about the Sacrum.
Being able to work with a very wide variety of horses this season, especially racehorses, it is really interesting to see how the sacrum affects the longevity of the whole horse, and how it affects performance.
Often when working on horses, most of my clients have heard me say that the sacrum isn’t moving properly. Let’s go over the importance of the proper movement of the sacrum.
Let’s start with the anatomy. The sacrum is a large triangular bone made up of the the five sacral vertebrae, which are fused together. This spinal segment plays a huge role in the locomotion of the ENTIRE horse, propelling motion to the front end. The sacrum is not only anatomically important in the role of locomotion, but it also houses the sacral nerves which provide parasympathetic autonomic innervation to the reproductive organs, as well as innervates the muscles of the hind end (such as glutes, femoral biceps, semi-tend, semi-memb, adductors of the hind end, just to name a few of the big ones).
Improper motion of the sacrum can affect the hind end not just in physical restriction, but in proper neural function as well.
Now let’s take a second to think about just HOW important the sacrum is. Every time your horse wants to even think about carrying their hind end properly, pushing off the hind end over a jump, or starting out of a gate, they cannot do so effectively without the proper motion of the sacrum.
Food for thought for racehorses & any horses expected to maintain speed over distances (endurance, eventing, barrel racing); how is a horse expected to be able to effectively maintain speed and stride without proper movement of their sacrum? Short answer: if the sacrum isn’t moving properly, they will not be able to.
However, the sacrum is not the only structure in the hind end. Improper movement of the pelvis, lumbar vertebrae, coxxes, Tuber coxae (hip), stifle, hock, fetlock, and even how the foot is balanced, can affect the motion of the sacrum. Not to the mention that compensation for the front end, proper organ function, saddle fit, and many other factors will play into the motion of the sacrum. Something as simple as getting your horse’s teeth done or at least checked, every year, can ensure proper motion of the TMJ, which will also affect the sacrum.
Taking all of this into consideration, it is important to look at the overall health of your horse, especially at a performance level. Every single aspect factors into the performance of your horse, as well as the movement of the sacrum, down to the one extra scoop of the latest supplement you add into your horses feed.
