A new study by Dr David Marlin has explored the shape of horses’ backs using cutting-edge 3D light scanning, revealing important differences between endurance and dressage horses and how these compare with commercial saddle designs.
The research, published with open access here, compared the thoracolumbar (back) profiles of 23 Arabian endurance horses and 21 advanced-level dressage horses. Using 3D scanning technology, Dr Marlin was able to capture accurate, non-contact measurements of the back at multiple points, offering greater detail than traditional flexicurve templating methods.
The study found that endurance horses had significantly narrower back profiles at the front of the saddle area compared to dressage horses, while differences at the rear of the back were less marked. These findings were then compared with saddle gullet bar angles, showing overlap with the range of widths offered by leading saddle manufacturers.
Dr Marlin explained that 3D scanning could offer a fast, accurate, and horse-friendly alternative for saddle fitters, saddle makers, and even owners. “The next step is to develop an app that would allow monthly scans to be sent to saddle fitters to monitor changes over time,” he said.
The research highlights the potential for modern technology to transform saddle fitting practices, improve welfare, and ensure a closer match between horse conformation and saddle design.
