Transversal Rotations in the Equine Vertebral Column.

  by Jean Luc Cornille

(In this study, the terms "Axial" and "Transversal" have the same meaning.) 

Lateral bending of the equine vertebral column is always associated with a movement of transversal rotation. As well, axial rotation is always coupled with lateral bending. "In the cervical and thoracic vertebral column, rotation is always coupled with lateroflexion and vice versa." ( Jean Marie Denoix, Spinal biomechanics and functional anatomy, 1999).

For the same lateral bending, two rotations are possible. One iscorrect, predisposing the horse to efficient use of his physique. The other one is inverted creating stresses and strains on the vertebral structures and consequently protective reflex contraction of the surrounding muscles.

Many riding and training principles, which have been conceived prior this knowledge, are unconsciously creating inverted rotation. These principles are ultimately hampering the horses' potential.

From the history of the scientific research to the practical application into riding and training principles, this abundantly illustrated study shows and explains how proper and inverted rotations look like, feel like, and can be corrected by appropriated riding techniques and gymnastic exercises
