Ground reaction forces, impulses, and their relationships to morphometric measurements were evaluated for walking gait in 17 healthy dogs. A force plate was used to record forces at 1-ms intervals. Vertical, craniocaudal, and mediolateral forces were measured and normalized by body weight. Impulses, defined as the total force applied over time, were(More)
Coefficients of variation were calculated for peak vertical force and for vertical, cranial, and caudal impulses recorded from the left forelimb and left hind limb of 5 dogs that were trotted across a force plate 5 times by 5 handlers. To determine the percentages of variance attributable to dogs, handlers, and trial repetitions, data recorded for each(More)
OBJECTIVE Evaluate the effect of marker placement on kinematics of the canine stifle in 3 distinct hindlimb models. STUDY DESIGN In vivo biomechanical study. ANIMALS Normal adult mixed-breed dogs (n=5). METHODS Ten retroreflective markers were affixed to the skin on the right rear leg of each dog to establish normal stifle kinematics. Four additional(More)
Present data describe the rates of vertical loading and unloading generated by clinically normal dogs in a trotting gait. Forward velocity was found to influence maximal rates of limb loading and unloading in forelimbs and hind limbs. The rates increased as the velocity of the dog/handler increased. The position of maximal limb loading during the stance(More)
OBJECTIVE To compare overground and treadmill-based gaits of dogs. ANIMALS 5 clinically normal adult mixed-breed dogs. PROCEDURES To obtain dynamic gait data, 30 retroreflective markers were affixed bilaterally to specific regions of the hind limbs and pelvis of each dog. For each dog, 3-D joint motion data (sagittal [flexion and extension], transverse(More)
The differences between velocities and accelerations obtained from three and five photocells were examined when obtaining ground reaction force (GRF) data in dogs. Ground reaction force data was collected 259 times from 16 different dogs in two experimental phases. The first phase compared velocities and accelerations reported by the two systems based on(More)
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(More)
The purpose of this study was to evaluate the effect of starting distance on the peak vertical force (PVF) and associated vertical impulses (VI) of normal dogs. Five dogs of similar weight and body type were trotted at a velocity of 1.6-2.2 m/s from each of three starting distances; 2, 4, and 6 m, from the first plate in a two plate test field. A total of(More)
