Summary
# Editorial Summary: Reliability of Equine Visual Lameness Classification Visual gait assessment remains the primary diagnostic tool for identifying lameness in equine practice, yet accumulating evidence suggests this approach has significant limitations, particularly when distinguishing sound horses from mildly lame individuals and when evaluating hindlimb lameness. Keegan's editorial commentary on Starke and Oosterlinck's findings reinforces conclusions from multiple peer-reviewed studies demonstrating that subjective visual evaluation lacks the reliability required as a standard of practice, with experience and self-perceived competence failing to improve diagnostic accuracy. Drawing on over 35 years of clinical experience, Keegan candidly acknowledges that even seasoned practitioners are regularly challenged and sometimes proven incorrect by colleagues, trainees and junior veterinarians—a humbling reality that exposes how easily subjective assessment becomes conflated with genuine expertise. Without objective measurement tools or external scrutiny, clinicians risk developing false confidence in lameness detection, mistaking consistency with accuracy. These findings underscore the professional imperative for equine practitioners across all disciplines to supplement visual observation with objective gait analysis technologies and seek collaborative assessment when lameness is suspected, rather than relying on traditional visual evaluation as a definitive diagnostic standard.

Practical Takeaways
- •Do not rely solely on visual lameness assessment, even if you have years of experience—objective tools (force plates, inertial measurement units, etc.) are necessary for accurate diagnosis
- •Mild lameness and hindlimb lameness are particularly prone to misdiagnosis through visual evaluation alone; these cases warrant instrumental assessment
- •Seek peer review and evidence-based validation of your lameness assessments rather than assuming experience guarantees accuracy
Key Findings
- •Visual gait assessment is unreliable for differentiating sound and mildly lame horses, particularly for hindlimb lameness
- •Clinician experience and confidence in ability to detect lameness does not improve reliability of visual assessment
- •Subjective evaluation for lameness should not be considered a satisfactory standard of practice
