Common Symptoms - Part 2
Atrophy behind the shoulder/of the trapezius muscle is extremely common to see at every level of riding and is caused when the saddle is fitting to the wither angle, as well as trees that are too narrow in the width (different than the angle). When a saddle tree is too narrow, it leaves no room for the lateral movement of the spine, as well as the flexion of the muscles during movement. An excess of pressure limits the blood flow and utilization of the muscle, both causing atrophy as well as an altered gait and posture that directly conflicts with the development of a healthy athlete. Abnormal posture is quite insidious in that it has a domino effect on other structures within the body, causing early wear and tear and additional impact and concussion on delicate structures along with compensatory muscling and an overall upside down way of going. A horse who is heavy on the forehand, leaning into the hands, dropped in the ribcage and not able to utilize the thoracic sling is predisposed to problems ranging from the poll to the hind legs if posture is not corrected.
Lack of mobility in the pelvis, pulling themselves along with the brachiocephalic muscle, ewe necked, sharp and angular topline as opposed to soft and round, heavy on the fore, prone to tripping, disunited, the list goes on.
Checking to see if a saddle pinches at the withers is fairly easy and straight forward. First and foremost you want to check the gap between the withers and the pommel, not just the vertical gap but also how much space is on the sides. You'd want to see a bare minimum of a 2 finger gap all the way around the withers (from one side, over the top, to the other). Secondly, the placement of the panels and the angle of the tree, with many panels placed too high namely due to the fact that the gullet points are simply too short in many saddles. Think of the trapezius as a river, and the arms of the gullet plate a bridge that needs to extend beyond the width of the river to not disturb the flow. Short tree points typically end within the trapezius, a muscle we know should not be carrying the weight of the rider, and as such, you see the atrophy as mentioned above. Ideally, the contact of your panel (and the tree points) begins 4" down from the edge of the spine where the D-ring of your saddle is, allowing the trapezius enough room to flex and develop without impingement.
