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)
Few quantitative data exist to describe the activity of the distal muscles of the equine forelimb during locomotion, and there is an incomplete understanding of the functional roles of the majority of the forelimb muscles. Based on morphology alone it would appear that the larger proximal muscles perform the majority of work in the forelimb, whereas the(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)
Understanding the pathophysiology of equine back problems, for clinical evaluation, treatment or injury prevention, requires understanding of the normal 3-dimensional motion characteristics of the vertebral column. Recent studies have investigated regional vertebral kinematics; however, there are no reported measures of direct in vivo segmental vertebral(More)
