In the past fifteen years great advances have been made in understanding the pathogenesis and treatment of laminitis. One of these advances is the use of the heartbar shoe. In theory the Chapman heart bar should work well for the treatment of laminitis, however, in practice favorable results depend on the proper application of the shoe along with supportive care of the foot.
