Yes, much development work was conducted on a treadmill. It certainly makes collection of stride data very convenient – if one owns a treadmill, but the treadmill creates artificial controlled conditions.
Based on some studies at the University of Missouri, it has been shown that the best way to evaluate lameness in the horse is not on the treadmill, but overground. On the treadmill horses move differently than overground. Forces on the limbs are different. On the treadmill you would expect increased horizontal impact on the limbs and a decreased requirement for hind limb propulsion. The horse simply has to pick up its legs, like running in place, to stay up. These differences make lameness on the treadmill much different than lameness over ground, the natural state of affairs. Lameness Locator was designed to use on horses traveling over
Therefore, if the intent is to assess and treat a clinical patient for lameness, we recommend conducting evaluations over
In summary, the lameness you measure on the treadmill can be much different than the lameness you measure over
