CASE STUDY: MOTION PROBLEM, CAUSE AND SOLUTION - SUMMER 2012
Problem: Stiff in hind legs. Loss of power at all gaits. Diminished response to leg aids.
Jane was pleased with her new saddle since the old one seemed to have pinched her horse’s back. She knew the old saddle was causing back discomfort because her horse traveled with his head high and a hollow back with an unwillingness to go forward. Now that she had been using the new saddle, her horse was traveling better, but she still felt he was short in the hind end and was not as responsive to her leg aid.
Jane called me three weeks after riding in her new saddle. She originally thought the motion problems she was experiencing were residual problems from her old ill fitting saddle. But three weeks after riding in her new saddle, she thought she had cause for concern.
When I arrived at the barn, Jane asked if I thought the new saddle could be causing the shortened stride and back discomfort. She was very worried because she spent a good amount of money on her new saddle. I reassured her that if the problem was of a muscular nature, we would be able to determine the cause and eliminate the problem by using the Wilson Meagher Method of Sportsmassage.
Assessment: I asked Jane to walk the horse in a straight line away from me and then toward me. I get the best view of muscular function at the walk. The slower the movement, the more muscle is used. The horse seemed short in both hind legs and walked quite stiff from behind. We brought the horse in the stall and I gently palpated his back with the flat of my hand. His lower back was slightly tight. His left and right gluteal muscles, which are called the rump, were quite tight, especially where they meet the back muscle up at the croup (sacrum). The two left and right gluteal muscles I palpated extend the hip and in conjunction with the back muscles are the main source of forward motion and power for cantering, galloping, jumping and collected work. The names of the two muscles are the gluteus medius and gluteal accessorius. If they are tight, I find that they may refer their tightness to the lower back.
Muscles contract and release. They also pull. That is all they do in terms of motion. If a muscle is tight, then it is the release process of the muscle that is effected. If we know that the gluteal muscles in Jane’s horse were tight, and the gluteal muscles extend the hip, then flexion of the hip will be effected because the muscle must release, or let go to do the opposite motion, as in flexing the hip. Flexion of the hip will bring the hind leg forward and underneath the horse’s body. Extension of the hip will bring the leg back and behind the horse’s body. Since the gluteals were tight in Jane’s horse, they were not able to fully let go and release for the horse to flex his hip and step forward and underneath his body. In summary, tightness in the mentioned gluteal muscles effect flexion of the hip and in terms of motion, will effect the hind leg stepping forward and underneath the horses body.
Cause: I assumed since Jane rode with an ill fitting saddle which pinched the horse’s back, the horse could not fully use its hind end because of the discomfort in the back caused by the saddle fit. The gluteal muscles tightened in response to the sore back. With the new saddle, the back tightness resolved itself somewhat, but the secondary gluteal muscle tightness remained.
