A horse leg orthosis employing a restrainer band is designed to prevent metacarpo-phalangeal joint (MCPJ) hyperextension of horse forelimb. Current band design by Manta Design Inc. produces inconsistent tensions and inadequately protects the forelimb. The goal was to improve the restrainer band design using a static analysis at MCPJ. Band length, cross-sectional area and stiffness effects were studied to meet the tension specifications from the static analysis. The improved restrainer band achieves an 8.4% MCPJ moment reduction at maximum extension
