Objective evaluation versus subjective evaluation of flexion tests in the pelvic limb of horses

Abstract

The agreement between subjective and objective evaluation methods was studied to identify claudication in the pelvic limbs of horses before and after flexion tests were performed. Twenty-nine horses were equipped with a wireless system of inertial sensors and evaluated during seven times while trotting. Videos were recorded to be evaluated by three veterinarians, with different levels of experience, to evaluate the agreement between the two different methods and between the evaluators. The evaluators and the objective evaluation had a low rate of agreement, with the exception of moderate agreement between the objective evaluation and evaluator 1 to identify lameness after the left total flexion and moderate agreement in evaluating the response to the tests, between objective evaluation and evaluator 2, after right distal flexion. This shows that there was a low agreement among the evaluators and between them and the objective evaluation for identifying lameness, measuring the degree of lameness and the response to the flexion tests.
