Abstract / Zusammenfassung

The ability to recognize movement pattern of lame horses accurately, requires practice and experience from equine clinicians. Hindlimb lameness evaluation is known to be more difficult than the forelimb counterpart. Even among experienced veterinarians agreement in hind limb lameness evaluation was only reported to be in acceptable range. This leads to the potential inaccuracy of subjective assessment of diagnostic analgesia. Moreover, veterinarians as subjective individuals are prone to bias. Therefore, numeral objective lameness measuring methods have been developed in the past decades in order to aid veterinarians. The objective system used in this study is a body-mounted inertial sensor system (BMISS) which has been proved to have adequate accuracy and sufficient repeatability. In the first study, the agreement among veterinarians (interobserver agreement) and the agreement between veterinarians and the BMISS have been investigated. The results emphasised that hindlimb lameness examination is challenging even for experienced equine veterinarians. The BMISS showed to have high agreement with clinicians in clinical live situation when evaluating hindlimb lameness, and with a group of highly experienced veterinarians when assessing the changes after diagnostic analgesia. These results should encourage the use of the BMISS as an aid in lameness examination. The second study has taken the benefits of the BMISS as a bias-free objective method to evaluate improvement of lameness after the analgesia of the deep branch of lateral plantar nerve (DBPLN) and the analgesia of the tarsometatarsal joint (TMT) in horses with suspected pain in the lower hock area. In 63% of the horses with suspected lower hock pain an improvement of lameness was observed after the analgesia of the DBLPN, but not after the analgesia of the TMT. Based on this result, the analgesia of the DBLPN did desensitise a different source of pain than the TMT analgesia. However, in the other 37% of the horses lameness improved after both analgesia. Therefore, it was not possible to differentiate source of lameness in this second group of horses. There are several possible explanations for the different pattern of lameness improvement in the 2 groups such as diffusion of anesthetic agent, inadvertent placement of the needle or concurrent pathologies. Nevertheless, since sonography and radiography were only the imaging modalities used in this study, it is still an open question what the exact cause of lameness was. In order to gain more understanding about the pathologies and improvement of lameness after these analgesia, similar studies using more advanced imaging modalities such as MRI or scintigraphy should be performed.
