When standing, does your horse stand square, or do his hind legs appear to be trailing out behind? When trotting or cantering, does your horse feel strung out? The cause could be that the pelvis has rotated. This can happen when a horse jumps a jump that is too big for his fitness level. Also, if the horse lands with his feet out behind and the rider sits down hard at the same time, the pelvis can be shoved into a position that causes pain in the stifle, hocks, croup, lower back, and even the withers. Myofascial release and stress point therapy can reverse this condition. Hand walking down a steep hill will encourage the horse to maintain the position after it is corrected. It may be necessary to include chiropractic treatment if the condition is severe.
