Resumo
A dorsalgia é uma causa comum de claudicação e redução de desempenho no cavalo atleta. Contudo, é ainda pouco compreendida atualmente, o que torna mais complicado o seu diagnóstico e posterior tratamento precisos, o que propicia recidivas a longo prazo. Atualmente, a análise cinemática se mostra um método objetivo de quantificar e analisar os movimentos dos equinos e consequentemente um método fiável para detetar se o animal tem um padrão biomecânico normal. Dentro das novas propostas terapêuticas, as ondas de choque tem vindo a ser um tratamento bastante utilizado para este tipo de patologia nos últimos anos, apesar das suas propriedades ainda precisarem de mais estudos para compreensão dos mecanismos de ação. Assim, o objetivo de este trabalho é demostrar, mediante a análise da cinemática do equino recolhida na passadeira aquática, os possíveis efeitos analgésicos das ondas de choque no tratamento da dorsalgia. Para tal, foram avaliados três equinos diagnosticados com dorsalgia, na passadeira aquática, em níveis diferentes de água. Existe uma alteração do padrão biomecânico do animal consoante o nível de água, e portanto foram obtidos mais dados sobre as variantes cinemáticas do animal. Foram utilizados pins cutâneos refletores para a recolha destes dados. Os programas Kinovea e MatLab® foram os escolhidos para realizar a análise dos mesmos. Os resultados deste trabalho só foram favoráveis no cavalo B. Contudo podemos concluir que, embora o número de animais utilizados no trabalho não seja o suficiente para realizar uma análise estatística dos dados obtidos, a literatura existente apoia que existe uma forte correlação entre as diferentes variantes cinemáticas e também suporta o forte poder analgésico das ondas de choque em afeções do dorso.
Back pain is a common cause of lameness and reduced performance in the athletic horse. However, it is still little understood today, which makes its accurate diagnosis and subsequent treatment more complicated, which leads to long-term relapses. Currently, kinematic analysis is an objective method to quantify and analyze equine movements and, consequently, a reliable method to detect whether the animal has a normal biomechanical pattern. Within the new therapeutic proposals, shockwaves have become a widely used treatment for this type of pathology in recent years, although its properties still need further studies in order to better understand the mechanisms of action. Thus, the objective of this work is to demonstrate, through the analysis of the kinematics of the horse collected on the aquatic treadmill, the possible analgesic effects of the shockwave in the treatment of back pain. For this purpose, three horses diagnosed with back pain were evaluated on a treadmill at different water levels. There is a change in the animal's biomechanical pattern depending on the water level, and therefore more data on the animal's kinematic variants were obtained. Reflector skin pins were used to collect these data. Kinovea and MatLab® programs were chosen to carry out their analysis. The results of this work were only favorable in horse B. However, we can conclude that, although the number of animals used in the work is not enough to carry out a statistical analysis of the data obtained, the existing literature supports that there is a strong correlation between the different variants kinematics and also supports the strong analgesic power of shock waves in back disorders. Keywords: Back pain; Kinematics; Water treadmill; Shockwave; Analgesia.
