A thorough understanding of the structure and function of the equine vertebral column can provide a clearer understanding of thoracolumbar spinal disorders. Three primary functions of the vertebral column include protection of the spinal cord, support for weight bearing, and flexibility for locomotion. Osseous structures provide structural support and vary(More)

A thorough knowledge of equine spinal anatomy, biomechanics, and potential pathology is required to understand the principles and theories behind chiropractic and to apply its techniques properly. Chiropractic provides additional diagnostic and therapeutic means that may help equine practitioners to identify and treat the primary cause of lameness or poor(More)
OBJECTIVE To evaluate biomechanical gait adaptations in dogs after amputation of a pelvic limb. ANIMALS Client-owned dogs (12 pelvic limb-amputee and 24 quadruped [control] dogs). PROCEDURES Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase. RESULTS Pelvic limb(More)
OBJECTIVE To characterize biomechanical differences in gait between dogs with and without an amputated thoracic limb. ANIMALS Client-owned dogs (16 thoracic-limb amputee and 24 quadruped [control] dogs). PROCEDURES Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance(More)
REASONS FOR PERFORMING STUDY An objective measure of neck, back and croup pain is needed in horses with musculoskeletal injuries, vague upper limb lameness or poor performance. OBJECTIVES To establish mechanical nociceptive thresholds (MNTs) within the axial skeleton and evaluate the effects of subject status and ridden exercise. METHODS Thirty-six(More)
REASON FOR PERFORMING STUDY Common methods used to treat back problems in horses need to be assessed objectively. OBJECTIVES To measure spinal mechanical nociceptive thresholds (MNTs) and evaluate the effects of chiropractic, massage and phenylbutazone, compared with active and inactive control groups. METHODS Baseline MNTs at 7 sites within the(More)
REASONS FOR PERFORMING STUDY Pressure algometry (PA) is a potential modality for objectively measuring mechanical nociceptive thresholds (MNTs) in horses. Its ability to differentiate musculoskeletal pain sites from nonpain sites is unknown and must be assessed prior to its clinical application. OBJECTIVES To assess the ability of PA to detect induced(More)
OBJECTIVES To establish reference mechanical nociceptive threshold (MNT) values of the equine thoracic limb and to assess the use of MNT values to detect pain associated with induced osteoarthritis in the middle carpal joint. ANIMALS 24 adult horses. PROCEDURES MNT values were evoked by a pressure algometer at 17 sites within each thoracic limb during 2(More)
Traditional investigations into the etiopathogenesis of canine cranial cruciate ligament (CCL) disease have focused primarily on the biological and mechanical insults to the CCL as a passive stabilizing structure of the stifle. However, with recent collaboration between veterinarians and physical therapists, an increased focus on the role of muscle activity(More)
OBJECTIVE To describe the incidence and types of gross osseous developmental variations and ages of physeal closure in the caudal portion of the thoracic and lumbosacral spine and the pelvis in a sample of Thoroughbred racehorses. ANIMALS Thoroughbred racehorses (n = 36) that died or were euthanatized at California racetracks between October 1993 and July(More)
