An equine-assisted therapy intervention to improve pain, range of motion, and quality of life in adults and older adults with arthritis: A randomized controlled trial.

Research Aim: To compare equine-assisted therapy to exercise education on pain, range of motion, and quality of life in adults and older adults with arthritis.

Background: Quality of life for adults and older adults is negatively impacted by arthritis pain, stiffness, and decreased function. Equine-assisted therapy provides unique movements to the rider's joints and muscles improving pain, range of motion, and quality of life and has improved outcomes in balance, gait, strength, functional mobility, and spasticity for older adults, stroke, spinal cord injury, and multiple sclerosis patients. No research has investigated the effects on adults and older adults with arthritis.

Methods: Twenty adults and older adults with arthritis recruited from rheumatology clinics participated in a randomized controlled trial for six weeks. Participants and research assistants were blinded to assignment. Standardized valid and reliable instruments were used to measure pain, range of motion, and quality of life targeting back, knees, shoulders, and hips.

Results: Mean age was 63.85 (SD 6.885, 53-75) years. Pain significantly improved in shoulders (p = 0.007), hips (p = 0.027), and back (p = 0.006), not knees (p = 0.061). Range of motion improved for back (p = 0.02), hips (p = 0.04), shoulders (p = 0.005) and not knees. Quality of life improved for upper limb (p = 0.002), lower limb (p = 0.021), and affect (p = 0.030), not social interaction and symptoms.

Conclusion: This randomized controlled trial provides evidence that equine-assisted therapy decreases pain, and improves range of motion, and quality of life for adults and older adults with arthritis. Further fully powered research with cost/benefit outcomes would be beneficial.
