Welcome to the EPR Drum Blog, a series of short writings about holistic horse health and a non-force approach to working with horses. Equine Positional Release (EPR) is a system of holistic horse health care. EPR utilises holistic health assessment, holistic non-force manual therapy, including the well being of the horse in the process of assessment and treatment. During the health assessment, the EPR practitioner observes the horse's posture, and notices behavioural and facial signs of pain.
