Pressure walkway measurement analysis in sheep


The baropodometry consists of the analysis of forces and weights related with each part of the foot. These data may be measurement during the locomotion or static body position. Since the few studies using the method in sheep and due to their importance as an experimental model for studying orthopaedic conditions, the aim of this study is to establish normal reference values in Brazilian sheep with different age groups to establish a database. Twenty-one clinically healthy Santa Ines sheep will be used. The animals will be divided into three groups according to age: Group I - 6-months-old, Group II - from one to two-years-old, Group III - from four to five-years-old. Each group will have four males and three females. A Tekscan pressure sensing walkway will be used. During each trial, the sheep will be conducted to walk in a straight line by a guide on the left side of the handler. The data from the first 5 valid trials will be taken for each sheep and will be analyzed using designated software (I-Scan version 5.231; Tekscan). Vertical force, vertical impulse, contact time, and velocity will be studied in both forelimbs and hind limbs. To compare between limbs in the same group or between groups the data will be submitted to Analysis of Variance (ANOVA) followed by the Tukey test. Differences will be considered statistically significant for p<0.05. All data will be analyzed using the GraphPad InStat software package (version 3.02). (AU)
