For many years, opinions on the value of flexion tests in assessing equine lameness have been divided. Now, new research has shown that a system based on a wireless, inertial sensor can be used to measure the horse’s response to a flexion test.
Horses were fitted with sensors on the head, pelvis and right forelimb. The sensors measured vertical pelvic movement asymmetry for both right and left hind limb strides and the average difference in maximum and minimum pelvic height between right and left hind limb strides.
The response to a hind limb flexion test was assessed by an experienced observer and compared with measurements taken with the horse trotting before and after flexion.
John Marshall, lecturer in equine surgery at the University of Glasgow, who led the study, concluded: “A positive response to flexion resulted in significant changes to objective measurements of pelvic symmetry, supporting the use of inertial sensor systems to objectively assess response to flexion tests.
