Standardized lameness scoring provides a welfare assessment framework enabling consistent evaluation of pain severity and treatment response in horses with locomotor conditions.
Lameness scoring welfare is fundamental because pain from locomotor conditions is one of the most prevalent welfare problems in horses and lameness assessment determines whether and how it is addressed. The subjectivity of visual lameness assessment creates variability that affects welfare outcomes — subtle lameness may be missed or attributed to training issues rather than pain. Objective inertial sensor systems reduce observer bias and detect asymmetries invisible to the human eye, potentially identifying animals requiring welfare intervention earlier. The welfare obligation to recognize and address lameness applies whether the horse is in competition, training or retirement. Systematic lameness surveillance using validated tools should be standard practice for all horses in regular work.
