Reasons to perform study. To assess lameness in animals, semi-objective scales are used. Video is sometimes used to enable blinding of the clinician. In addition, the assessment of pain is particularly difficult in animals since they cannot report their feelings. The interpretation of the reactions of the animals can be different between observers. A method to quantify pain is the measure of mechanical nociceptive thresholds (MNT), a method called algometry. Since synovitis is often linked to swelling of periarticular tissues and to synovial fluid effusion, palpation of the joint is also a useful test. The objectives of the current study were to assess in sheep whether (1) video assessment of lameness is in agreement with real observation; (2) algometry of the knee is correlated with lameness evaluation; (3) algometry is correlated with identification of swelling by palpation. Material and methods. The population of sheep enrolled in a controlled trial at the Ovine Research Center of UNamur was used for the current study. Results. There was a moderate inter-rater agreement (value of kappa was 0,41) between the experimenter who evaluated the ewes on site and the one who watched the videos. No significant correlation was identified between lameness scores and algometry. A negative correlation (algometry reactive threshold is lower when palpation score is higher) was identified between palpation scores and MNT (P<0.05). Discussion. Video assessment can be used in research to assess lameness. The experience of the observer must be taken into account. Algometry is not entirely valid since an adaptation or learning process seems to develop in sheep. [less ▲]Detailed reference viewed: 16 (2 ULg)

BACKGROUND: Various treatments of osteoarthritis (OA) have been described, including use of nutraceuticals. OBJECTIVES: To review systematically the literature about the effects of nutraceuticals on clinical signs of pain or abnormal locomotion in horses, dogs, and cats, and to discuss methodological aspects of trials and systematic reviews. METHODS: A systematic search of controlled trials evaluating the impact of nutraceuticals on OA in horses, dogs, and cats was performed, using Medline, CAB Abstracts, and Google Scholar. Scientific evidence was evaluated by means of criteria proposed by the Food and Drug Administration (FDA), and a scoring system adapted from both the CONsolidated Standards of Reporting Trials (CONSORT) statement and recommendations for assessing trials by the Center of Evidence Based Medicine of Oxford. RESULTS: Twenty-two papers were selected and reviewed, with 5 studies performed in horses, 16 in dogs, and 1 in cats. The strength of evidence was low for all nutraceuticals except for omega-3 fatty acid in dogs. There were limited numbers of rigorous randomized controlled trials and of participants in clinical trials. CONCLUSIONS AND CLINICAL IMPORTANCE: The evidence of efficacy of nutraceuticals is poor, with the exception of diets supplemented with omega-3 fatty acids in dogs. Greater access to systematic reviews must be part of the objectives of the veterinary science in the future. Their reporting would be improved by internationally agreed-upon criteria for standards and guidelines. [less ▲]Detailed reference viewed: 41 (2 ULg)
