Model of horse's back movement

Abstract
Riding horses are subject to a considerable load on the back, which leads to an increasing incidence of back disorders. Even with the use of diagnostic measures, such as radiology, scintigraphy, sonography, and blood analysis, in many cases the precise diagnosis of back pain remains challenging and pathogenesis cannot be established. Additionally, the differentiation between primary back pain, and secondary back pain, originating in a painful limb, is difficult. Biomechanical models of the human back have already led to the developement of new therapeutic strategies.
Our aim is to establish a biomechanical model of the equine back and neck, based on kinematic and electromyographic data of 15 horses without back pain. Additionally the influence of the rider will be assessed with a saddle pad measuring pressure distribution. The model will allow the simulation of normal back movements and restrictions thereof.
Primarily the equine back and neck will be modelled as a simple elastic beam with temporary and localized changes of rigidity. The model is then tested comparing it to the back movements of horses, and optimized if necessary.
The resulting model should allow isolation of single influencing factors on the back motion of the horses, and it will be applied both for clinical routine and for teaching.
