Is your horses face symmetric ?
There can be many reasons why your horse has asymmetry in their cranium. Your horse may have suffered a fall or pulled back when tied up. Which then has misaligned the cranium bones. Or the nuchal ligament is pulling unevenly on the nuchal crest so the occipital bone has become twisted. This will then have an affect on the other cranium bones.
Having asymmetry in the face can cause restrictions and strain patterns thought out the whole body, which could cause behavioural problems as we well as issues when ridden.
When treating your horse I will begin by checking your horses face to see if there are any asymmetries present. This will then give me an idea where there could be other restrictions in your horses body. This lovely mare has regular CST treatments, the asymmetries are starting to correct themselves and her movement has improved greatly
