Spatial distribution of normal and shear strain, as well as SED, in the MCIII during a 2 m/s walk, 5 m/s trot, and 8 m/s canter. Despite the large changes in strain magnitude and speed, the patterns of strain components about the cortex remain relatively stable, with only slight shifts in SED evident from walk to trot to canter. Posterior (ventral) surface of the MCIII is toward the bottom; medial aspect is to the left.
