Abstract

Pesq. Vet. Bras. 34(12):1265-1270, dezembro 2014 1265 RESUMO.-[Análise cinemática da marcha de cães Golden Retriever saudáveis.] A análise cinemática relaciona--se com o movimento relativo entre corpos rígidos e encontra aplicação na análise da marcha e de outros movimentos do corpo. A interpretação de seus dados, quando há alteração, determina a escolha do tratamento a ser instituído. O objetivo deste estudo foi padronizar a marcha do cão Golden Retriever saudável visando auxiliar no diagnóstico e tratamento de afecções músculo esquelética. Neste estudo utilizou-se um sistema de análise cinemática para analisar a marcha de sete cães da raça Golden Retriever, fêmeas, idade entre 2 e 4 anos, peso variando de 21.5 a 28 kg, clinicamente sadias. Dados morfométricos foram coletados para descrever a população estudada. Variáveis de tempo e distâncias foram mensuradas para descrever a marcha, movimentos de flexão e extensão foram descritos para as articulações do ombro, cubital, cárpica, do quadril, femorotibial e társica. A marcha foi caracterizada lateral e teve hipótese de normalidade aceita para todas as variáveis, exceto para o apoio de quadril e apoio de cúbito, considerando um grau de confiança de 95%, ou seja, nível de significância α = 0.05. As variações foram atribuídas ao deslocamento das tarjas durante o movimento e ao repetido número de avaliações. A análise cinemática provou ser um consistente método de avaliação do movimento durante a marcha canina e os dados obtidos podem ser utilizados no diagnóstico e na comparação em avaliações de marcha para outros estudos e tratamento de cães com afecções musculoesqueléticas. Kinematic analysis relates to the relative movement between rigid bodies and finds application in gait analysis and other body movements, interpretation of their data when there is change, determines the choice of treatment to be instituted. The objective of this study was to standardize the march of Dog Golden Retriever Healthy to assist in the diagnosis and treatment of musculoskeletal disorders. We used a kinematic analysis system to analyse the gait of seven dogs Golden Retriever, female, aged between 2 and 4 years, weighing 21.5 to 28 kg, clinically normal. Flexion and extension were described for shoulder, elbow, carpal, hip, femorotibialis and tarsal joints. The gait was characterized lateral and had accepted hypothesis of normality for all variables, except for the stance of hip and elbow, considering a confidence level of 95%, significance level α = 0.05. Variations have been attributed to displacement of the stripes during movement and the duplicated number of reviews. The kinematic analysis proved to be a consistent method of evaluation of the movement during canine gait and the data can be used in the diagnosis and evaluation of canine gait in comparison to other studies and treatment of dogs with musculoskeletal disorders.

Digital analysis of the dog’s gait as a tool for early diagnosis of locomotor dysfunction – case study

“…Although the way of movement is characteristic for the breed, body type or individual predispositions [DeCamp et al 1993, Allen et al 1994, Clements et al 2005, Kano et al 2016, numerous sources present the assumptions of the general model of musculoskeletal function for a given species and despite significant variability within it, it does not affect however significant deviations from the model of angulation of individual joints during movement [Hottinger et al 1996, Bertram et al 2000, Breur et al 2014. This is indicated by slight differences in the angular ranges obtained in the study and available in specialist literature describing the features of the labrador and rottweiler movement apparatus [Agostinho et al 2011, Silva et al 2014]. The differences between the results obtained from the analysis of dog movement in our research and those described in Labradors and Rottweilers [Agostinho et al 2011, Silva et al 2014] are small, and the overall model of movement in the joints is similar.…”

Schaefer et al [1998] in their research show that each joint has a characteristic flexion and extension pattern and that no variables were detected in the distance between the left and right side, suggesting symmetry of gait.…”

Kinematics of healthy American Pit Bull Terrier dogs

“…A kinematic gait analysis in healthy dogs has been addressed by some authors (Jarvis et al 2013;Silva et al 2014;Kopec et al 2018). However, none of them addressed the gait in healthy American Pit Bull Terriers.…”

Inertial properties of the German Shepherd Dog

“…Many kinematic [ 4 , 12 – 14 ] and kinetic [ 15 – 17 ] studies have described gait characteristics of dogs, with some including inverse dynamics to determine joint force, torques and powers [ 18 – 20 ] however these have not included the contribution of segment inertial properties [ 21 ]. Editorials on canine research state that there is a lack of body segment parameter data [ 22 ] and a “…need to develop a database of accurate limb segment morphometric descriptions for specific (dog) breeds, and accumulate a database of normal, breed-specific joint kinetics….” [ 23 ].…”
