背痛
Back pain in a horse may be caused for a variety of reasons. Saddle fit, poor riding technique, lack of conditioning, overwork, accidents, or lameness can all contribute to back pain. A saddle that is not fitted properly on the horse may lead to immediate, acute pain, or chronic, long-term damage. A saddle of ill fit will repeatedly bruise, pinch, or rub the underlying soft tissue or spinal processes. A horse that is not athletically fit may also experience back pain. Abrupt changes in work, footing, or terrain can make even a fit horse suffer soreness. Accidents, missteps, or awkward jumps all lend themselves to strain. Compensating for any type of limb, joint, or hoof injury can make a horse put extra stress on its back, which can lead to back problems in addition to lameness if not treated promptly. A rider with a poor seat can put abnormal pressure directly on a horse's back, or may indirectly cause back pain in other ways: An ill-fitting bit and bridle or bad hands, resulting in mouth pain, can cause secondary back pain as the horse lifts its neck and stresses its back to avoid the pressure to the mouth.
