Evaluation of Stress Response of Horses in Equine Assisted Therapy Programs 2004



H. M. Suthers McCabe & L. Albano



This exploratory study was designed to measure stress in therapy horses. Plasma cortisol was used as physiological marker of stress. Each horse was videotaped during the therapy session and tapes were reviewedfor conflict indicators. Blood was drawn
from a total of28 horses of approximately J5 different breeds, with 5 horses participating on two separate days for a total of 33 samples. Blood was drawn prior to a therapy session and again immediately after the session was completed. As a group, cortisol levels decreased by a mean of 24.07 nmol/L with a standard error of 5.993 and p=0.0003. The results indicate that 82% of these therapy horses are not experiencing significant physiological stress.
