Drs Karen Wild and Claus have developed a way to measure the relaxation affects of manual treatments on horses. Listen to their innovated approach to measuring relaxation and how it was develop and what their future plans are for further developments. Dr. Claus is an MD, PhD and on the faculty at Northwester Medical College and Dr. Wild is an equine massage therapist in Sweden. We believe their innovations will be an important tool for future assessments in autonomic nervous system measurements.
