Range of motion and between-measurement variation of spinal kinematics in sound horses at trot on the straight line and on the lunge
Fig 3
Between-measurement variation (offset adjusted data) for ‘Whole Back Flexion-extension’ (calculated as the angle between the two segments ‘withers—T15’ and ‘T15—tuber sacrale’), per measurement, per day and per horse (measurement-mean data).
Black lines indicate 95% prediction intervals.
