Abstract

The equine veterinarian uses diagnostic tools. Test results must be reproducible under different circumstances in order for these diagnostic tools to be deemed useful. The results of the tests performed can be interpreted correctly if the reliability of these tools is known. Existent indices of reliability are the kappa concordance coefficient and the intraclass correlation coefficient. This article illustrated these coefficients in the context of the tests and tools used to assess horse locomotion. The scientific literature suggests that the assessment of mild lame-ness remains insufficiently reliable and is not dependent on the level of expertise of the veterinarian. Various connected tools have been developed to clarify the measurement of locomotion abnormality. Limitations on the use of these «machines» have been reported. It is important to continue to develop these tools but also to clarify their reliability and validity.
