Step 1 - What Are You Trying to Measure?

Step 1 - What Are You Trying to Measure?

By Kevin Keegan Kevin G. Keegan, DVM, MS, DACVS | Updated on | Editorial, KG Keegan, Objective vs. Subjective Opinion

Kevin G. Keegan, DVM, MS, Diplomate, American College of Veterinary Surgeons I often get asked by colleagues and fellow equine lameness investigators to compare inertial sensors to other methods of objective lameness measurement. My question in return is, “What are you trying to measure?" In my honest opinion, if you are only interested in measuring lameness in horses, for whatever reason, then the only way to do it practically today is with body-mounted inertial sensors. If you are interested in measuring something else, for example rider position on the horse, limb movement effects with shoeing, or if you are interested...

An Open Letter to Veterinary Colleagues

An Open Letter to Veterinary Colleagues

By Kevin Keegan Kevin G. Keegan, DVM, MS, DACVS | Andy Wolter Andy Wolter, Equinosis CEO | Updated on | A Wolter, KG Keegan

Introduction From Andy Wolter, CEO, Equinosis: Dear reader, Nearly every day there is a reason I am optimistic about the future of science & objectivity in equine veterinary medicine.  But, now and again, I am reminded of how far we still have to go. Reading a 2020 article titled “Is the use of objective gait analysis inevitable?” seems like debating whether the Earth really is flat – if you just keep your feet on ground.  The evidence on objective measurement is in, and it is irrefutable. A lack of education is certainly at play for many detractors of science.  But...

When Subjective Opinion Disagrees with Inertial Sensor Measurements

When Subjective Opinion Disagrees with Inertial Sensor Measurements

By Kevin Keegan Kevin G. Keegan, DVM, MS, DACVS | Updated on | Data Collection, Data Interpretation, Editorial, KG Keegan, Objective vs. Subjective Opinion, OES Members Only

Whenever I use the Equinosis Q, which is on every lameness case, treatment checkup, or pre-purchase, I also always do a subjective lameness evaluation, determining and often times declaring my subjective impression regarding where (i.e. which limb or limbs) I think the lameness is. Sometimes there is disagreement between my subjective opinion and the results of the inertial sensors. What is my take on this? The short and easy answer is, "I was probably wrong". This happens occasionally and it no longer bothers me or my clients, or the students or house officers I am training. I am...

Man with Machine Versus Man Without Machine: Debunking the Myths

Man with Machine Versus Man Without Machine: Debunking the Myths

By Kevin Keegan Kevin G. Keegan, DVM, MS, DACVS | Updated on | KG Keegan, Objective vs. Subjective Opinion

The Debate: A debate continues to fester around the topic of comparing subjective to objective evaluation of lameness.  The problem is, in its current form, the debate is not a genuine examination of the appropriate question – what is the most transparent and, therefore, best information that can be provided to horse owners? Instead the debate has been oddly twisted to pit man VERSUS machine – as if every new machine replaces the man, instead of complimenting his or her abilities, like the microscope, or telescope, or the wheel! Unfortunately, this debate further devolves into mischaracterizations and falsehoods,...
