Fig. 2 While standing on a stool, the operator has the horse's head elevated by a handler using a twitch handle as an aid in extension. Moving the horse's head up and down quickly in this manner often produces a spontaneous movement of the left arytenoid cartilage.

Fig. 3 The handler places a finger at the commissure of the horse's lips and pulls back quickly and firmly to stimulate movement of the reinnervated arytenoid cartilage, which is visible via endoscopy. The reflex works on either side of the mouth. Veterinary Clinics: Equine Practice 2003 19, 189-208DOI: (10.1016/S0749-0739(02)00073-1)
