🔬 For everyone who asked to see the research in more detail, the full pre-publication paper is now available to read on Animalweb.❗
The preliminary study by Dr David Marlin, Russell MacKechnie-Guire, Graham Cross and Rachel Murray investigated the complex forces acting through the curb rein, cheekpiece and curb chain when a horse was ridden in a double bridle. 🐴
The full paper includes:
📊 Detailed tension measurements
📡 The sensor and data-collection setup
🖼️ Illustrations of how forces act through the bridle
⚙️ Estimates of the forces transmitted inside the horse’s mouth
🔎 A full discussion of the findings and limitations
