Achieving Dynamic Balance.
This video does show that watching a horse move can be a valuable tool in achieving dynamic balance. The method of trimming used was the HPT Method that I have been teaching for nearly 20 yrs. The HPT Method was published in an American Farriers Journal article in 2002 titled "A Table with all the Trimmings". I believe the article is now published as a supplement hand out by the AFJ and can still be had. Any method that results in dynamic balance and a sound horse is a good method. The key I believe is to teach a method that offers good results, and proves consistent and repeatable.
Below are my comments on bi-lateral wedging, I welcome your comments.
It is my belief that bi-lateral shimming/wedging that involves the
lateral cartilages is an exercise in futility when the goal is to balance the limb and top line of the horse, that is why these particular wedges were used. Any wedging or building up of the hoof wall should be for the purpose of establishing dynamic balance of the hoof capsule to the hoof's internal foot. Maintaining dynamic load to the coronary band is important. Reconstruction of weak structure or missing structure is not wedging.
The lateral cartilages form the caudal foot, and depending upon several factors retain correct conformation for proper foot function, or alter in response to improper stimulus resulting in a loss of proper foot function. Some of these factors include palmar process conformation and length, load, and degree of elastic potential. It is the level of elastic potential that establishes the range of load that the lateral (ungular) cartilage can withstand before conformation change occurs. In some cases the cartilages will simply be displaced proximally, returning to normal conformation when the cause of displacement is removed. In those cases where extracellular matrix degradation occurs (loss of elastic potential and increase in elasticity occurs) cartilage goes through conformational change, with these changes often resulting in hoof deformities. Regardless of the balance method disregard for the conformation of foundations of the equine foot will more often result in hoof deformity.
