Abstract

The present research project has the main objective the evaluation of the qualitative characteristics (B mode and elastogram findings) and quantitative (quantification of pixels and shear velocity) of the pectineus muscle of healthy dogs and those with hip dysplasia. Will be use 46 dogs, considering 15 healthy animals and 31 with hip dysplasia. For selection of experimental sampling, dogs of different races, weighing between 25 and 50 kg, ages between 2 and 6 years old, male or female will be included. Radiographs will be performed on dogs of both groups to examine the hip joints. B mode ultrasonography and ARFI elastography of the pectineus muscle will be performed bilaterally in both groups of healthy dogs and with signs of osteoarthrosis or hip laxity. Statistical analysis will be performed with software R. Initially, the normality of residues (Shapiro test) and homoscedasticity of variances (Barlett test) will be tested. The quantitative variables will be compared between healthy and diseased animals by analysis of variance (ANOVA) in a randomized block model, whereas the qualitative variables will be compared by the Friedman test. Ultrasound and clinical parameters will be correlated by Pearson or Spearman correlation tests. Statistical significance for all tests will be set at 5% (p <0.05). (AU)
