Researchers in the United Kingdom recently conducted a study to determine whether upper airway issues detected during exercise were revealed during resting and dynamic endoscopic examinations.
Scientists at the University of Glasgow's Weipers Centre Equine Hospital fitted yearlings at a racing stable with a special bridle and saddle pad carrying an endoscope, and performed analysis while the horses were resting, longeing at a canter for five minutes, and immediately after exercise.
“We identified a high prevalence of dorsal displacement of the soft palate, as well as a number of other pathologies that were not identified during resting endoscopic examination, such as vocal cord collapse and medial/axial deviation of the aryepiglottic folds (tissue spanning from the arytenoid to the epiglottis that collapses across the opening to the trachea),” Padraig Kelly, MVB, MRCVS told The Horse.
Kelly said further research is needed to clarify the significance of these pathologies, but it would appear that dynamic endoscopy is a better means of identifying problems that crop up during exercise than resting scopes.
