Great read on compensation 👏🏻👏🏻👏🏻
“Ohhh this horse just has a little arthritis in his left hock, it doesn’t seem to bother him too much.”
Horses are prey animals and therefore great compensators; they will create alternative locomotive patterns to continue movement.
So, say this little bit of osteoarthritis causes a reduced range of motion of the tarsal joint. In an attempt to maintain stride length and hide this dysfunction to potential predators (because you never know when a lion could be waiting around the corner... or a flapping plastic bag!) the tarsal (hock) joint is rotated medially (inwards) during the swing phase of the stride. This results in asymmetrical & medial weight bearing through the digit (hoof). This places additional stress through medial hamstring muscles, resulting in muscle tension and trigger points. And this is all something that is potentially going on in the affected hindlimb.
A hip hike/drop can occur at corresponding phases of the stride, placing the sacroiliac joint under stress, resulting in paraspinal and asymmetrical gluteal tone/pain.
Decreased impulsion from the left hindlimb leads to increased weight bearing through the right forelimb diagonal. This can create tension and hypertrophy to the right pectoral muscles and related fascial planes.
The spiral of compensation could continue on further, affecting cervical muscles that become hypertonic as a result of weight shifting, digit shape and size, TMJ pain, head tiling, hyoid dysfunction, asymmetric tail holding...
Check ligaments may strain on the overloaded limb, saddles may slip, mouths may open, head shaking may happen. And that doesn’t mean we have to put on a flash noseband, non-slip saddle pads and wear spurs to get more impulsion from the left hind that is through and through p a t h o l o g i c a l.
Often it can be the case where I see a horse that is a chronic stage of compensation and it can be difficult to find the true cause especially when the horse may appear just overall “stiff”.
I liken the rehabilitation of chronic cases to peeling the layers off an onion; one layer at a time and piece by piece to unravel and rewind the compensation spiral. 🐴
If this sparks a thought in anyone’s mind that actually, their horse may be suffering with this kind of pain presentation — follow your gut, trust that you know what is best for your horse and have your vet, physio, farrier, nutritionist, saddler, trainer all work with you and your horse to improve their comfort 🥰
