Lameness Locator Moves Equine Veterinary Technology a Step Ahead

While not without its detractors, some vets believe this system helps make subjectivity less of a factor in lameness exams

Dr. Kacey Tweeten-King of Brock Veterinary Clinic in Lamesa, Texas, readies the Lameness Locator for an evaluation of a perfect candidate for the machine. The mare’s lameness was mild, and results showed problems in two limbs.

Over the years, and with the help of co-inventors P. Frank Pai and Yoshiharu Yonezawa, the Lameness Locator was born. The first unit was sold late in 2009, and the steadily rising number of machines in use today is over 50, 12 of which are in vet schools.
