Riders systematically underestimate lameness in horses they are riding — research is now quantifying this perception gap and developing tools to close it.
The rider perception gap is a structural welfare problem in equestrian sport: horses with objectively confirmed lameness are regularly ridden and competed because riders cannot reliably detect the movement asymmetry. The gap has multiple drivers — habituation to a familiar horse's gait, biomechanical feedback distortion from the saddle, and the psychological tendency to interpret movement changes as training issues rather than pain. Technological solutions now exist: inertial sensor systems that provide real-time symmetry feedback effectively extend rider perception beyond unaided detection limits. Wider adoption of these tools — including their use in warm-up at competitions — would allow earlier detection and treatment of lameness, substantially improving welfare for performance horses.
