FAQ: Can the Q be used on a gaited horse?

By Kevin Keegan Kevin G. Keegan, DVM, MS, DACVS | Updated on | Data Collection, Data Interpretation, FAQ, Gaited Horses, KG Keegan

In general, the ambling (single foot, or 4-beat) gaits decrease the vertical movement of the horse's trunk, making it easier to “sit”. Consequently, to maintain some vertical momentum, the horse’s vertical head movement becomes exaggerated.  Because of the way The Q (Lameness Locator®) displays results relative to “expected” vertical movement, this may cause underestimated forelimb lameness, overestimated hind limb lameness, and increased variability.  Also, for the ipsilateral gaits, the evaluator must flip the hind limb results (i.e. reported RH lameness is really LH lameness), because the inference of footfall from the right forelimb gyroscope is off by ½ of a stride cycle, (i.e. the left hind foot is on the ground when it is assumed that the right hind limb foot is on the ground).     For The...

If you ever have trouble connecting to your sensors or experience sensor lag (sensors plotting asynchronously across the screen) as horse gets farther away, the following is a quick check list to run through for possible reasons.  For more in-depth troubleshooting, click HERE to view the complete Bluetooth® Sensor troubleshooting guide. Check that your sensors are sufficiently charged and turned on. If you have more than one set of sensors in your system, make sure you are attempting to connect to the correct set. If any sensor is a new replacement, the sensor must be programmed into the system (contact...

FAQ: What's a Q Score, and How Can I Use It?

FAQ: What's a Q Score, and How Can I Use It?

By Kevin Keegan Kevin G. Keegan, DVM, MS, DACVS | Updated on | Data Interpretation, FAQ, KG Keegan

"Quantification of Asymmetry": In Lameness Locator® 2017, Equinosis introduced a report metric called the Q Score. The Q score, or quantification of asymmetry, is a summary of the measurements that provides the limb, timing and amplitude of asymmetry, irrespective of whether the asymmetry is above or below defined thresholds.  There is one Q score for the forelimb evaluation and a combined Q score for the hind limb evaluation. The Q scores are different for fore and hind. Because the upward and downward movement of the head is related (due to its attachment to the torso via the neck, which acts...

FAQ: Does the size of the horse matter in using Lameness Locator®?

FAQ: Does the size of the horse matter in using Lameness Locator®?

By Kevin Keegan Kevin G. Keegan, DVM, MS, DACVS | Updated on | Horse Size, KG Keegan, Locked, Reference Range, Software Navigation

The reported Q thresholds were established in a sample of horses of varying size without standardization due to size. But, 6 mm of asymmetry in pelvic height between right and left hind limb strides in a 1500 lb. Clydesdale is most certainly less indicative of “lameness” than the same (6 mm) in a 200-lb. miniature horse. In 2014, this size-dependent factor was accounted for algorithmically. However, the standardization, instead of being based on size, is based on expected normal vertical movement. After all, it is not really the size of the horse that determines its amplitude of vertical...
