“…This study aimed to assess the impact of a tactical harness on thoracic limb kinematics during walking and trotting, using an established model of the canine thoracic limb. 8 Differences were detected in both kinematic waveforms and angular displacements between dogs wearing and not wearing a tactical harness. Therefore, the hypothesis was rejected.…”

“…A previously established three-dimensional thoracic limb kinematic model was utilized in this study. 8 On the day of collection, dogs were trotted and walked through the calibrated testing space, approximately 15 times each, at 1.7 to 2.1 and 0.9 to 1.2 m/s, respectively, and acceleration between À0.5 and 0.5 ms 2 . Velocity and acceleration were recorded by 5 in-line photocells.…”

Objective The aim of this study was to assess the impact of a tactical harness on three-dimensional motion of the thoracic limb in dogs. Animals Five adult mixed-breed dogs (age: 4–6 years, weight: 25–35 kg) were used in this study. Methods Custom-fit tactical harnesses were applied to each dog and 19 retroreflective skin markers were used to determine three-dimensional joint motion during dynamic motion, with and without the harness. Sagittal plane (flexion–extension), transverse plane (internal–external rotation), and frontal plane (abduction–adduction) kinematics were created for the shoulder, elbow, and carpus from motion capture data, with and without the harness. Kinematic waveforms were analysed using statistical parametric mapping paired t-tests (a = 0.05). Angular displacements were determined, and total joint range of motion was compared using paired t-tests (a = 0.05). Results Wearing a tactical harness increased sagittal angular displacement in the elbow but decreased it in the shoulder and carpus. Significant differences were found in the kinematic waveforms in almost all joints at both a walk and trot. Dogs wearing the tactical harness had reduced flexion and increased abduction of the shoulder joint at a walk. The elbow joint had increased extension, reduced external rotation and increased abduction at both walk and trot. The carpus had reduced flexion at a trot and walk, as well as increased internal rotation and abduction at a walk. Conclusion Wearing a tactical harness affected kinematic gait data of all joints of the forelimb. The elbow was affected in all three planes at both a walk and trot, while the shoulder joint was only affected at a walk when wearing a tactical harness. Clinical Relevance The clinical impact of wearing a tactical harness is unknown at this time, particularly when dogs are performing their duties while wearing harnesses.

Objective The aim of this study was to compare a Joint Coordinate System (JCS) three-dimensional (3D) kinematic model of the canine forelimb with more widely used linear (LIN) and segmental (SEG) 2D models. Study Design It was an in vivo biomechanical study. Animals Normal adult mixed breed dogs were used in this study (n = 6). Methods Nineteen retroreflective markers were applied to the skin of dogs' right forelimbs. Dogs were trotted and walked through the calibrated testing space. The first five good trials were used to generate sagittal plane (flexion and extension angle) waveforms from 3 different models (JCS, LIN and SEG) for the shoulder, elbow and carpal joints. The JCS model also generated transverse and frontal plane joint angular data (internal/external and abduction/adduction angles) for all three joints. Minimum, maximum and total angular displacement was calculated for each joint. Comparison of sagittal plane waveforms was performed before and after waveform alignment using statistical parametric mapping. Results Each model produced similar sagittal plane waveforms, though the LIN model had a greater vertical shift along the y-axis for the shoulder and elbow. Before waveform alignment, differences were revealed between the LIN model when compared to JCS or SEG model at a trot. No differences were revealed at a walk. After waveform alignment, no differences were revealed between models at a walk or trot. There were no differences in angular displacement measurements between models before or after waveform alignment at a walk or trot. Conclusions The 3D JCS model reported in this study produced sagittal plane waveforms comparable to conventional 2D models while also providing joint specific information from other planes of motion.
