A Randomized Controlled Trial Comparing Equine-Assisted Therapy and Exercise Education for Adults and Older Adults with Arthritis
Abstract
Arthritis creates pain, stiffness, and decreased functionality affecting adults’ and
older adults’ quality of life. Equine-assisted therapy provides unique movements to the
rider’s joints and muscles improving pain, range of motion, and quality of life. No research
has investigated the effects of equine-assisted therapy (EAT) on adults and older adults with
arthritis. The purpose of this pilot study of a convenient sample was to assess the feasibility
and acceptability of conducting a randomized controlled trial comparing an EAT
intervention with an exercise education attention (ExEd) control intervention. A review of
literature, methods, settings, procedures, results, discussion, limitations, and conclusions are
included. This study was registered with clinical trials.gov, approved by the University of
Missouri-Kansas City Institutional Review Board, and followed Consolidated Standards of
Reporting Trials guidelines. Settings included a Professional Association of Therapeutic
Horsemanship International (PATH)-certified riding stables with PATH-certified riding
instructors administering the EAT intervention, and Saint Luke’s College of Health Sciences
for the ExEd attention controlled intervention. Twenty-one consenting participants were
randomized and single-blinded to assignment. Dose consisted of a one hour intervention,
once a week for six weeks. Measurements occurred at baseline, three weeks, and six
weeks. Outcomes included back, knee, hip, and shoulder pain, and range of motion, quality
of life, and enjoyment of nature. Biomarkers measured cartilage and muscle status. Results
supported the feasibility and acceptability of the research design, protocol, and
methods. Findings indicated significant improvements in back, hip, and shoulder pain, and
back and hip range of motion. Quality of life measures had significant improvements over
time for upper limb, lower limb, and affect, but not for symptoms and socialization. No
significant results were obtained in Cartilage Oligomeric Matrix Protein biomarkers, serum
troponin T, and enjoyment of nature. Limitations include small sample size, confounding
variables, and threats to validity. The protocols and methods were feasible and acceptable.
Continuing EAT after the study was not acceptable. Biomarkers may not be sensitive or
specific enough for this research. A tool to assess the barn environment should be
developed. Large multi-center trials will provide important generalizable information in
future EAT researchers.
