Objective—To evaluate a 3-D kinematic model of the hind limb developed by use of a joint coordinate system in dogs. Animals—6 clinically normal adult mixed-breed dogs. Procedures—17 retroreflective markers were affixed to the skin on the right hind limb of each dog. Eight infrared cameras were arranged around a gait platform to record marker locations as dogs were recorded moving through the calibrated space 5 times during a walk and trot at velocities of 0.9 to 1.2 m/s and 1.7 to 2.1 m/s, respectively.
Randomised controlled clinical trial for the use of deracoxib during intense rehabilitation exercises after tibial plateau levelling osteotomy.
During intense physical exercise, the cyclo-oxygenase-2 (COX-2) pathway is upregulated which contributes to soreness. The aim of this study was to determine if there was a clinical affect of deracoxib (COX-2 selective antagonist) on dogs engaged in intense rehabilitation following tibial plateau levelling osteotomy for cranial cruciate ligament rupture. Our hypothesis was that dogs receiving deracoxib would demonstrate less lameness, better range-of-motion (ROM), and faster muscle mass recovery than the control dogs.
Temporal-spatial gait analysis by use of a portable walkway system in healthy Labrador Retrievers at a walk.
Objective-To establish a protocol to collect temporal-spatial gait analysis variables by use of a portable walkway system in Labrador Retrievers at a walk and to determine reference values. Animals-56 healthy Labrador Retrievers. Procedures-6 passes across the walkway (3 passes in each direction) were recorded. Inclusion criteria for a pass were that the dog was at a walk (velocity, 60.0 to 90.0 cm/s) and had minimal head turning. The first 3 passes that met the inclusion criteria were analyzed for each dog. Results-Mean stride length was 88.4 cm.
OBJECTIVES: To evaluate range of motion (ROM) of the pelvic limb in healthy dogs descending stairs compared with decline slope walking.
Serum cortisol concentration and force plate analysis in the assessment of pain associated with sodium urate-induced acute synovitis in dogs.
Objective-To determine the relationship between serum cortisol concentration and pain severity as measured by force platform gait analysis in dogs with experimentally induced synovitis of the stifle joint. Animals-10 healthy hound-type dogs. Procedures-Dogs underwent 2 study phases. In the first phase, serum cortisol concentration, systolic arterial blood pressure, heart rate, and gait data were obtained at 0 (first sample), 2.5, 5, 7.5, and 10 hours.
Objectives: To evaluate range of motion (ROM) of the pelvic limb in healthy dogs descending stairs compared with decline slope walking. Methods: Reflective spheres were placed on the skin over the joints of the right pelvic limb of seven adult, hound-type dogs with no clinical signs of orthopaedic or neurologic disease. Five trials of stair and ramp descent of each dog were recorded using four 60 Hz digital infrared cameras. Two-dimensional kinematic data were collected as dogs walked down stairs and on a continuous decline of equivalent slope.
Kinematic motion analysis of the joints of the forelimbs and hind limbs of dogs during walking exercise regimens.
OBJECTIVE: To assess forelimbs and hind limb joint kinematics in dogs during walking on an inclined slope (uphill), on a declined slope (downhill), or over low obstacles (cavaletti) on a horizontal surface and compare findings with data acquired during unimpeded walking on a horizontal surface. ANIMALS: 8 nonlame dogs (mean +/- SD age, 3.4 +/- 2.0 years; weight, 23.6 +/- 4.6 kg).
Validation of an Experimental Testing Apparatus Simulating the Stance Phase of a Canine Pelvic Limb at Trot in the Normal and the Cranial Cruciate-Deficient Stifle: An In Vitro Kinematic Study
Journal: Veterinary Surgery
Objective: To design an experimental testing apparatus simulating a quasi-static model of the stance phase at a trot for a normal and a cranial cruciate ligament (CCL)-deficient stifle under near physiologic conditions.
Study Design: In vitro biomechanical study.
Animals: Paired pelvic limbs (n=6) from 3 dogs, weighing 29.5–31 kg.
Comparison of a bioimpedance monitor with dual-energy x-ray absorptiometry for noninvasive estimation of percentage body fat in dogs.
OBJECTIVE:To assess performance of a portable bioimpedance monitor for measurement of body composition in dogs. ANIMALS: 24 client-owned dogs. PROCEDURES: Percentage body fat was measured via dual-energy x-ray absorptiometry (DEXA) and with a portable bioimpedance monitor, and body condition score (BCS) was measured by use of a 9-integer scale. RESULTS: Although the precision of the bioimpedance monitor was good, this varied among dogs. Body position (standing vs sternal) had no effect on bioimpedance results.

Articular cartilage has a poor intrinsic capacity for healing. The goal of surgical techniques to repair articular cartilage injuries is to achieve the regeneration of organized hyaline cartilage. Microfracture and other bone marrow stimulation techniques involve penetration of the subchondral plate in order to recruit mesenchymal stem cells into the chondral defect. The formation of a stable clot that fills the lesion is of paramount importance to achieve a successful outcome.
