Pelvic Instability in Horses
In canter your horses hind outside leg, at one phase of the gait, is the only leg in contact with the ground. It takes the horses full weight in that moment.
- The horse in the photo is an example of how the hind outside leg is taking the entire weight of the horse and rider at one phase of the canter.
Any pain, imbalance or instability will show up when your horse is on the opposite rein to the hind leg with the issue i.e a problem in the right hind will show up in canter on the left rein.
A horse who is sore or unstable in the hind end may have trouble with maintaining an even rhythmic canter, disunite, struggle to perform collected movements, rush or stop at jumps especially as the height increases, frequently break/trot in canter work, prefer to work on the forehand, drop/trip/glitch/catch or catch in the hind end.
Usually, if the horse struggles with canter on the left rein (because of a right hind issue) it will struggle on the right rein in trot, when the sore/unstable leg is on the inside. (The same pattern happens in reverse).
This instability and imbalance can be caused by many different issues
- SIJ dysfunction
- Pelvic stabiliser tears/strains
- Pelvic stabiliser muscle atrophy
- Improper training and strengthening programme
- Unfit, overweight or underweight horses
- Compensatory patterns coming from issues/pain in other regions of the body
- Rider imbalances
- Old scar tissue or gelding scar pain
- Incorrect saddle fit
- Incorrect or poorly managed hoofcare
🔸 How to we prevent pelvic instability?
It’s important to incorporate pelvic stabiliser strengthening exercises into your riding regardless of what discipline you ride. Lateral movements and trotting poles are the best for this, as well as collected work, lots of transitions and hill work.
When doing this sort of conditioning with your horse you need to be mindful that, because these muscles are weak and underconditioned, it will take time to build and re-strengthen them. These exercises should be incorporated into your training scheduled and should be added in slowly. Horses will feel muscle soreness the same way that we do when they start using muscle groups that they haven’t used in a while.
💢Your horse will not be able to perform these exercises correctly if they have restrictions and soreness in their bodies - it’s best to have them treated by a qualified professional first and then continue with a strengthening and conditioning programme.
If you are a jumper, you must not ignore your flat work! A horse with a strong and stable pelvis will jump in a much more balanced and controlled fashion due to the power they are able to generate from their hind end.
If your horses hooves are not trimmed/shod correctly - long toes, low heels or unbalanced levels etc - your horse will be unable to work in a way that is biomechanically correct and will not be able to strengthen the correct muscles for normal patterns of movement and stability. Just like with who you choose to treat your horses bodies, you should be carefully choosing qualified professionals for your horses hoofcare.
