A study will be conducted to assess if adults and older adults with arthritis who ride horses are able to move better, have less pain, enjoy nature more and have a better quality of life then people who go to class to learn about exercise. This is needed because adults with arthritis experience joint pain, stiffness, damage to their cartilage, and decreased range of motion in their hips, knees, shoulders, and back. This study will measure effects on patient's joints, pain, quality of life, muscle and cartilage before and after either arthritis exercise education or horse riding. Horses have unique movements that target joints without weight bearing and possibly show improvements without joint damage.
