Abstract:
Lameness in the horse is a problem that often occurs. Even experienced veterinarians often do not agree in the diagnosis of lameness (STASHAK, 1989). There are standardized methods for the diagnosis of lameness; however, there is still no objective, technical method available for use in daily practice. The causes of lameness can be wide spread. Therefore, the horse as a whole must always be examined. Ten horses from the Clinic for Horses of the Veterinarian Medicine University of Vienna were randomly chosen from the herd. The measurement system was developed by Dr. Peter Schramel. It consists of an acceleration sensor, a data transfer connection and computer software (Lameness Detection Programme (LDS VO.93)). The ten subjects were outfitted with the measurement system and were trotted before two veterinarians who delivered their opinions independently. The measurements of the accelerometer produced good results. A normal distribution was assumed. Using all measured data, 95% were correctly identified as lame or not lame. Likewise with the data from the head. With the data from the saddle it was 90%. The data from the sacrum even delivered 100% accuracy. In the evaluation of the lame cases, the use of all data showed a 90% success rate. The same applies to the data from the saddle and the sacrum. With the data from the head, the rate was only 80%. The accelerometer measurements were compared to the findings of both veterinarians. The veterinarians were also compared to each other. The agreement of the two veterinarians was significant. Veterinarian 1 was generally a little more conservative in his evaluation, and veterinarian 2 generally graded the lameness half a degree higher. This test series showed that with the help of acceleration sensors, not only can it be determined whether lameness exists but it can also be determined which leg is affected. It was shown that the results of the accelerometer correlate with the findings of the veterinarians. The small number of subjects must be viewed critically. Further studies would be desirable in order to confirm these results.
