The purpose of the proposed research is to assess the feasibility, acceptability and effects of equine-assisted therapy on adults and older adults with arthritis. Equine-assisted therapy (EAT) is defined as any intervention using the unique qualities of horses to improve social, gross motor, and self-help skills.(Ratliffe & Sanekane, 2009) Although equine therapy has been used as a medical intervention since the second century (Ratliffe & Sanekane, 2009), no research has been conducted using equine-assisted therapy to improve arthritis.
