The role of ridden lameness evaluation

The lameness diagnostician relies on the ability to recognise symmetrical (sound) and asymmetrical (lame) gaits. Historically, gait assessment (i.e. the lameness examination) is performed while the horse is walking and trotting with its handler. This method of lameness evaluation dominates the equine veterinary literature and is the basis for nearly all lameness grading systems. It is the best way to assess a ‘head nod’ and/or ‘pelvic hike’ upon which lameness is localised to a limb or limbs. Despite its inherent value, the horse’s gait in-hand may not accurately represent the gait in the ridden horse. This is particularly true in sport horses when specific movements, sport-specific gaits, and/ or changes of pace such as canter-to-trot transitions are not only training but competition elements of the horse’s performance. For these athletes, the role of the ridden lameness evaluation becomes an important diagnostic tool for the lameness detective ...
