Performance lameness does not always present as a clear head-nod or limp. In many sport horses, discomfort in the neck, back, or pelvis shows up first as subtle performance decline rather than obvious limb lameness.

The multifidus muscle is one of the horse’s most important spinal stabilizers, providing core strength and postural control. When it weakens due to pain or inactivity, the horse loses stability and may develop chronic back pain or conditions like kissing spine. This article explains the multifidus’ role in equine biomechanics and how targeted rehabilitation at Kinetic Equine Medicine in Monroe, Washington restores balance, strength, and performance.
