Here’s why a horse not being strong enough through their core is not the whole picture… 💭
When we discuss a positive posture, it’s not all about core engagement. A series of musculoskeletal factors need to work synergistically to create this uplifting suppleness for positive posture.
⭐️ LUMBAR BACK MUSCLES ⭐️
If these muscles have tension, you can often find the pelvic angle will tilt forwards. If you tilt your pelvis forwards, you will feel the contraction of your lumbar area and a kind of disinggaement of the flexibility/ability to flex the lumbar spine.
Spinal flexion is what occurs when the core engages; as the core lifts, the spinal column is in a state of supported flexion. If you round your back, and engage your core, you will feel your back lift. This is a super mobile position, and if you try and bend left and right you’ll find this easier than if you tilt your pelvis forwards.
So, pelvic position is a super important precursor to core engagement.
⭐️ INTERCOSTAL MUSCLE HYPERTONICITY ⭐️
The intercostal muscles are a part of the core muscle network that can be palpated in between the ribs. When this rib network becomes sore, the ability to have softness through the ribcage for the engagement of core muscles on curves and through transitions can be challenging. This can often occur as a secondary effect to dysfunctional pelvic position through compensation mechanisms.
⭐️ CRANIAL DISPLACEMENT OF THE SCAPULA ⭐️
This is an interesting one I have seen in horses with forelimb pathologies, likely as at least a partial result of the overloading of the forehand. But fairly often, in the more acute cases, I will see this in horses with ill-fitting saddles. The increased tone of the cervical trapezius muscles draw the scapula forwards out of the way of the saddle, and is often accompanied by atrophy to the thoracic trapezius. This can happen on a very subtle scale. I find this is quite a good example of how core engagement would not solve this horses way of going until the original pathology was identified.
I hope this will provide a little insight into why having a horse strong through their core muscles is not always the only factor as to why posture is compromised.
