Equine Distress Index ®
The Equine Distress Index
® (EDI ® ) is a 10- point proprietary scale that makes understanding your horse’s
wellbeing easy. The lower your horse’s EDI ® score, the happier and healthier they are.
To determine your horse’s EDI ® score, sensors in your device acquire biometric and behavior data while
processors analyze this data in real-time to compute an EDI ® score (1 to 10) . Your horse’s EDI ® score is a
measure of deviation from their unique and normal baseline parameters that are determined during an initial
Learning Period of approximately 80 hours (refer to
Learning Period ).
Fuzzy Inference Parameters
Your horse’s EDI ® score is an
objective measure of their relative
distress and general wellbeing and
derived using a fuzzy inference
system with multiple weighted
parameters, including biometric
data, behavioral inputs, pre-
condition factors, and more.
•
Biometric data (HR, respiration)
• Behavioral inputs (activity level)
• Pre-conditions or risk factors
(medical history, routines, diet)
Learning Period
To establish baseline parameters for your horse’s personal distress algorithm and model,
an initial Learning Period of approximately 80 hours is required. Progress and %
completion of the Learning Period is found within the Summary section on the App. As
y
our horse continues to wear their device, the more precise your horse’s personalized
algorithm and model will become.
Learning Period should be conducted while your horse is healthy and in their
normal/natural environment. For example, if you would like to be alerted to possible
signs of distress in your horse while they are unsupervised overnight in their stall, then
have them wear their device overnight in their stall. If you are more concerned about
their health and wellbeing during the day while turned out in a pasture or paddock, then
have them wear their device while turned out during the day.
NOTE : Smart alerts and EDI ® scores are only available after an initial “Learning Period” (refer to Smart Alerts ).
