title: Kinematic and temporospatial assessment of habituation of Labrador retrievers to treadmill trotting.
abstract: This study investigated differences in kinematic and temporospatial variables in treadmill-naïve dogs when introduced to treadmill trotting and the time required to for them to become habituated to the treadmill. Twenty-four healthy Labrador retrievers, with an age range of 22-36 months and with no history of orthopaedic disease, were included in the study. A motion capture system registered kinematic variables of the carpus, elbow, tarsus and stifle, along with stride time and stance duration, at 240 Hz. Six sessions, each lasting 8-10 min, walking and trotting on the treadmill were performed with each dog, with three sessions on each of two consecutive days. The between-stride variability of total angular displacement of the carpus, elbow, stifle and tarsus, as well as the stride and stance time, was higher during the day 1 trotting sessions than in the last session of day 2. These stabilised to non-significant levels before the second session on the second day of measurements and thus habituation was achieved.
