Flexion testing in equine pre-purchase examinations raises welfare questions about the appropriate use of a painful diagnostic procedure.
Flexion test welfare illustrates how routine veterinary procedures can impose welfare costs that may not be justified by their diagnostic value. The procedure causes measurable discomfort and positive results can indicate pathology or simply pain sensitivity - creating ambiguity about what the result actually means for the horse's soundness. The welfare-appropriate approach critically evaluates whether the discomfort imposed is justified by diagnostic benefit, and considers whether less invasive alternatives can provide equivalent or superior clinical information. This kind of ongoing welfare evaluation of standard procedures is a mark of progressive veterinary practice.
