Topic:Clinical Examination
Clinical examination in horses involves a systematic evaluation of the animal to assess its health status and identify any potential medical issues. This process typically includes a thorough physical assessment, which may cover observation of behavior and posture, palpation of body structures, auscultation of heart and lung sounds, and examination of the skin, eyes, and mucous membranes. Additional diagnostic tools such as thermography, endoscopy, or imaging techniques may be utilized to gather more detailed information. Clinical examination serves as a foundational step in veterinary diagnostics, aiding in the detection and management of diseases or injuries in horses. This page compiles peer-reviewed research studies and scholarly articles that explore methodologies, advancements, and findings related to clinical examination practices in equine medicine.
