Systematic lameness investigation using nerve blocks, imaging, and clinical assessment enables accurate diagnosis and targeted treatment — protecting horses from unnecessary procedures and unaddressed pain.
Lameness investigation serves a direct welfare function: identifying the source of pain allows targeted treatment rather than symptomatic management that may mask without resolving the underlying condition. The diagnostic nerve block process — progressively desensitizing regions to identify where anesthesia abolishes lameness — is temporarily uncomfortable but welfare-positive overall by directing treatment accurately. Without systematic investigation, horses may receive treatments for the wrong condition, continue performing through unaddressed pain, or be labeled difficult when pain is the behavioral driver. Objective lameness assessment using sensor systems and force plates removes the subjective bias of clinical observation and enables detection of subtle bilateral lameness that symmetrical clinical presentation masks. The welfare case for thorough lameness investigation is compelling: accurate diagnosis enables appropriate treatment, and treatment enables pain-free movement.
