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.

Saddle fit isn’t just about comfort—it directly affects biomechanics, spinal motion, and long-term soundness. Research shows rider weight, balance, and saddle design all influence pressure, posture, and performance.
