DSMD (idiopathic hopping) is a commonly missed cause of front-end pain in horses, linked to dysfunction of the scapular and thoracic sling rather than the lower limb. Learn the signs, why it’s often overlooked, and when veterinary evaluation matters.

Spooky or resistant behavior under saddle is often an early sign of pain, not a training problem. Facial expression and performance changes can reveal underlying biomechanical dysfunction long before visible lameness appears.

When pain persists beyond tissue healing, the nervous system itself may be driving discomfort. Central sensitization and neuropathic pain help explain exaggerated reactions, inconsistent movement, and behavior changes in horses.

Some horses continue to show pain, tension, or behavior changes long after an injury has healed. Peripheral sensitization helps explain why normal touch or movement can become painful—and how early intervention can break the cycle.
