Abstract
Palmar foot pain is an important chronic problem that impairs the abilities of sport horses. Though there are several research on different types of horses, there is a lack of information regarding polo horses, which are known for using in unique sport. Therefore, this research aimed to find the prevalence of palmar foot pain in polo ponies with forelimb lameness in Thailand. The horses included in this study were 30 Argentine polo ponies: 10 geldings and 20 mares, aged from 7 to 20 years old. All were barefoot and had not exercised for at least 2 months. The ponies underwent lameness examination procedures with subjective and objective evaluation, including a trot on a straight line, left and right lunging, a full forelimb flexion test and a toe wedge test. Close inspections of hoof conformation, hoof percussion and hoof testing were done before performing a palmar digital nerve block. The result showed that 25 (83.33%) of 30 polo ponies had forelimb lameness, which can be divided into 56.7% with unilateral forelimb lameness, and 26.7% with bilateral forelimb lameness. There were 17 (56.7%) polo ponies that responded positively to the full flexion test and 25 (83.33%) that responded positively to the hoof tester and percussion at the frog area. However, only 9 ponies (30%) were positive to palmar nerve block. In conclusion, this study reveals a notable incidence of forelimb lameness and palmar foot pain. Understanding palmar foot pain prevalence is vital for further equine health management.
