Introduction to the Lameness Locator by Equinosis
July 6, 2015
Blair Doon Veterinary Hospital is excited to announce a new service to our equine clients! We are privileged to be one of two facilities in the state of Kansas to own and operate the inertial sensor system, AKA the Lameness Locator.
The Lameness Locator is an equine motion instrument developed for evaluating lameness on a quantitative level. This instrument was designed at the University of Missouri led by Dr. Kevin Keegan, DVM and Dr. Frank Pai, a mechanical and aerospace engineer. The locator aids with subtle lameness and compensatory lameness. The beauty of this tool is its ability to quantify the efficacy of diagnostic nerve blocks. This gives an objective aspect to the standard subjective methods used in lameness evaluations. In addition, this tool can be used to determine if the patient is responding to therapy and treatments.
According to Dr. Keegan, the Lameness Locator can detect motion at a frequency of 200 times per second whereas the human eye can only detect motion at 20 times per second at best. The ability to utilize a tool that can observe motion ten times faster gives an advantage to pinpointing difficult lameness. This can effectively remove bias that is commonly seen with the standard subjective evaluations.
How does it work?
The lameness locator consists of two accelerometers (one placed inside a head bumper and another attached to the dorsal midline of the pelvis) and one gyroscope (placed around the right front pastern). These sensors will then send wireless data to a tablet computer while the horse is jogging. Specific and unique algorithms are used to calculate immediate information to determine the severity and type of lameness.
