How does the DigiGait system compare to other gait analysis systems?
The DigiGait system does not require external reflective markers to be attached to the animal for gait analysis, whereas other systems may require markers. DigiGait directly collects digital video images of the underside of animals, whereas other systems may use a mirror to reflect the ventral view of the animal to a camera. As a consequence, image clarity, color, and shades are best preserved by DigiGait. The DigiGait system enables the user to select a range of walking speeds, whereas other systems expect the animal to walk [or not walk] at its preferred walking speed. This feature of DigiGait is important since there may be no gait abnormalities at a slow walking speed, but a high walking speed may demonstrate important differences. Moreover, even subtle differences in walking speed may have profound effects on gait indices.
