FIG. 1.

Reference lines for measurement of lateral and ventral tail deviation. (A) Ventral deviation (angle A) was calculated from a line connecting the greater trochanter of the femur to the tail base. (B) Lateral deviation (angle B) was calculated from the middle of the tail to a line parallel with a line drawn between the cranial border of the iliac crests.
