Thoracic Sling (what is it??)
Did you know horses don’t have a structure similar to collarbones? While you might not think that means much, it means everything in a horses biomechanics. Think about where some the most important organs are in the horse, in their front end between the forelegs. Think about how heavy they are. Now when you look at the orientation of the horses body gravity is working against these organs, and the only thing stopping it is a complex of muscles, ligaments, and other soft tissue structures. The diaphragm is not placed in an area to support and no bony structures directly support these organs. Furthermore, these same muscles are what connect the shoulder to the body, suspending it between the neck and the thorax of the body. So the only thing suspending this “sling” (heart, part of the lungs, shoulders) is soft tissue! So imagine that any one part of this complex muscle system is weak. Now we have compensation. And a dropping of these structures. If these muscles are dysfunctional, it can lead to numerous issues. Self Carriage issues, gait issues, inability to lift their shoulders and engage from behind, and even proprioception and balance issues. A lot of times we can see a weak thoracic sling through movement and musculature. Most of these horses will consistently want to go very hollow with their head up, with a tendency to fall in and travel with little impulsion from behind. They may be reactive when asked to come into a frame or stand up in the corners. This isn’t always poor behavior, but sometimes the horse is just trying to provide an answer with what they’re able to work with! These horses need soft tissue support, and a program designed to help their thoracic sling function correctly! I address thoracic sling dysfunction through various soft tissue modalities and provide tailored stretches and mobility exercises to help strengthen and promote the longevity of the musculature. If you’re wondering whether or not your horse may have thoracic sling dysfunction, shoot me a message and I’d love to help!
