A laboratory system for production of flexion rates and forces in the forelimb of the horse

Am J Vet Res. 1978 Mar;39(3):365-9.


The distal portion of the forelimb of the horse is provided with a stay apparatus composed of tendons, ligaments, and fascia. This stay apparatus provides the major resistance to joint flexion during the support phase of the stride. The laboratory test system described was shown to be able to reproduce in vitro limb motions and hoof forces measured with a running horse. These results indicated the stay apparatus operates in a largely passive mode, active muscle contraction apparently serving to provide rigidity only early in the support phase of the stride. The testing system described was designed to take advantage of the passive nature of the stay apparatus in order to study in vitro the forces, accelerations, and deformations encountered by the limb of the galloping horse in vivo.
