Abstract
Una de las principales patologías en caballos atletas son los problemas de claudicaciones, ya sea por problemas en tendones, ligamentos, estructuras articulares etc. Anteriormente las pruebas diagnósticas o de valoración de las claudicaciones en caballos se realizaban de manera subjetiva. Esto puede provocar que no concuerden los criterios entre colegas a la hora de evaluar estas patologías, sobre todo en claudicaciones muy sutiles. En la actualidad ya existen métodos objetivos útiles que permiten estudiar y cuantificar el patrón locomotor y la marcha de los caballos; uno es el análisis cinemático y otro método es el análisis cinético. Cada método posee ventajas y desventajas. En general, el análisis cinemático describe el patrón locomotor del caballo y el análisis cinético explica la causa de este. Estos métodos son muy sensibles a los cambios en el patrón locomotor normal de los caballos, permitiendo cuantificar y observar la actividad locomotora, ya sea en animales con algún problema de claudicación o, inclusive, para la evaluación de patrones de ataxia.Algunos caballos, durante el examen de cojera, tienen comportamientos nerviosos y se excitan al ser transportados a alguna instalación o al realizarles algún test, pudiendo esto enmascarar la cojera, siendo a veces necesaria su tranquilización. Las fenotiazinas son fármacos que provocan sedación, indiferencia al ambiente y reducción de la actividad motora. Muchos de esos efectos son impredecibles entre individuos y pueden provocar efectos adversos como hipotensión. Se ha descrito también el uso de acepromacina en protocolos de sedación como ayuda a la hora de evaluar cojeras, aunque en algunos caballos es necesario un mayor grado de tranquilización...
One of the main pathologies in athletic horses are lameness problems whether due to condition involving tendons, ligaments, joint structures etc. Previously, diagnostic or evaluation tests of lameness in horses were performed subjectively. This may lead to inconsistent criteria among colleagues when evaluating these pathologies especially in very subtle cases. At present there are already useful objective methods allowing to study and quantify the locomotor pattern and the gait of the horses; kinematic and kinetic analysis. Each method has advantages and disadvantages. In general the kinematic analysis describes the locomotor pattern of the horse and the kinetic analysis explains the cause of movement. These methods are very sensitive to changes in the normal locomotor pattern of horses, allowing to quantify and observe the locomotor activity, either in animals with some lameness problem, or even, for the evaluation of ataxic patterns.Some horses behave nervous or exited during lameness exam, or while performing some tests, this being able to mask the lameness being sometimes necessary their tranquilization. Phenothiazines are drugs that cause sedation indifference to the environment and reduced motor activity. Many of these effects are unpredictable among individuals and may cause adverse effects such as hypotension. The use of acepromazine in sedation protocols has also been described as an aid in the evaluation of lameness although in some horses a greater degree of tranquilization is necessary...
