Summary

Velocities obtained from a five photocell system were compared to velocities of nine anatomical points on a handler and canine subject as reported by a kinematic system over the same distance. There was not a statistically significant difference between the velocities of the markers on the dogs’ occipital protuberance and interscapular region compared with the velocity as reported by the photocell system. The average velocities of the three markers on the forelimb of the dogs and three markers on the handler's leg and one on the sacrum had statistically different values than the photocell system. Given these results, photocell systems with the same configuration in this study can be trusted to report accurate trunk velocities of canine subjects during the collection of ground reaction forces.
