Topic:Lameness

Lameness in horses is a condition characterized by an abnormal gait or stance due to pain or mechanical dysfunction affecting the limbs or spine. It is a common issue in equine practice and can result from a variety of causes, including injury, infection, or degenerative diseases. Lameness can affect a horse's performance and quality of life, making accurate diagnosis and management important for equine health. Diagnostic techniques often include physical examination, imaging, and gait analysis. This page aggregates peer-reviewed research studies and scholarly articles that explore the etiology, diagnostic methods, and management strategies for lameness in horses.
