Figure 1

Evolution of the different gait variables with age . Each GRMD dog is represented using its own symbol (see table 1). The healthy population is represented by a grey zone, covering the mean (grey line) ± 1 SD (black lines). A: evolution of the motor score in GRMD dogs; B: evolution of the speed normalized by the height at withers (HW); C: evolution of the stride length normalized by the height at withers (HW); D: evolution of the stride frequency; E: evolution of the total power; F: evolution of the force; G: evolution of the medio-lateral part of the power; H: evolution of the regularity.
