health area of equine-assisted therapy became subject to a major rift when a second group, the Equine Growth and Learning Association (EAGALA) formed in 1999, splitting from EFMHA (now PATH) over differences of opinion about safety protocols. Since that time, additional differences have arisen between the two groups over safety orientation, the therapeutic models used, training programs for practitioners, and the role of riding. EAGALA itself had a further split between its founders in 2006 due to legal issues, with yet another new organization formed. As a result, although PATH and EAGALA remain the two main certification organizations in the United States, there has been a significant amount of misunderstanding amongst practitioners, client, and within the scientific literature. To resolve these differences, an independent organization, the Certification Board for Equine Interaction Professionals (CBEIP) formed, beginning in 2007, to promote professional credibility in the field. However, the world of equine-assisted psychotherapy remains disorganized and has not standardized its requirements for education or credentialing. History Horses have been utilized as a therapeutic aid since the ancient Greeks used them for those people who had incurable illnesses. Its earliest recorded mention is in the writings of Hippocrates who discussed the therapeutic value of riding. The claimed benefits of therapeutic riding have been dated back to 17th century literature where it is documented that it was prescribed for gout, neurological disorder and low morale. In 1946 Equine Therapy was introduced in Scandinavia after an outbreak of poliomyelitis. Hippotherapy, as currently practiced was developed in the 1960s, when it began to be used in Germany, Austria, and Switzerland as an adjunct to traditional physical therapy. The treatment was conducted by a physiotherapist, a specially trained horse, and a horse handler. The physiotherapist gave directives to the horse handler as to the gait, tempo, cadence, and direction for the horse to perform. The movement of the horse was carefully modulated to influence neuromuscular changes in the patient. The first standardized hippotherapy curriculum would be formulated in the late 1980s by a group of Canadian and American therapists who travelled to Germany to learn about hippotherapy and would bring the new discipline back to North America upon their return. The discipline was formalized in the United States in 1992 with the formation of the American Hippotherapy Association (AHA). Since its inception, the AHA has established official standards of practice and formalized therapist educational curriculum processes for occupational,
