Stenosing tenosynovitis of the abductor pollicis longus muscle causes chronic front limb lameness in dogs. The lesion, similar to de Quervain's tenosynovitis in people, is caused by repetitive movements of the carpus. Thirty dogs with front limb lameness, painful carpal flexion, and a firm soft tissue swelling medial to the carpus were examined prospectively. Seven dogs had bilateral abductor pollicis longus tenosynovitis.
RADIOGRAPHIC AND ULTRASONOGRAPHIC DIAGNOSIS OF STENOSING TENOSYNOVITIS OF THE ABDUCTOR POLLICIS LONGUS MUSCLE IN DOGS.

Objective-To compare results of single-point kinetic gait analysis (peak and impulse) with those of complete gait waveform analysis. Animals-15 healthy adult mixed-breed dogs. Procedures-Dogs were trotted across 2 force platforms (velocity, 1.7 to 2.1 m/s; acceleration and deceleration, 0.5 m/s(2)). Five valid trials were recorded on each testing day. Testing days 1 and 2 were separated by 1 week, as were days 3 and 4. Testing days 1 and 2 were separated from days 3 and 4 by 1 year.

Background Sprinting, jumping, stopping, turning and movement initiation produce the highest forces and largest ranges of motion in the canine gait, yet very little is known about them. Objective The purpose of this study was to develop a general kinematic sequencing of maximal movement initiation of Greyhounds using joint angles and a segmental diagram. Design Seven Greyhounds conducted maximal movement initiation trials on a vegetated surface by chasing a lure.

Pelvic Limb Kinematics and Surface Electromyography of the Vastus Lateralis, Biceps Femoris, and Gluteus Medius Muscle in Dogs with Hip Osteoarthritis.
Journal: Vet Surg
To measure the activity patterns of the vastus lateralis (VL), biceps femoris, and gluteus medius (GM) muscle at a walk in sound dogs and dogs with hip osteoarthritis (OA).
Dogs (n = 10) with hip OA and 7 clinically sound dogs.
Self-reflective markers and a high-speed camera system were used for kinematic measurements and surface electrodes were used for the electromyography (EMG). All measurements were performed on walking dogs. Maximal, minimal, and mean values of the joint angles were evaluated, together with the surface EMG data.
Effects of trial repetition, limb side, intraday and inter-week variation on vertical and craniocaudal ground reaction forces in clinically normal Labrador Retrievers.
Objectives: To document the contributions of trial repetition, limb side, and intraday and inter-week measurements on variation in vertical and craniocaudal ground reaction force data. Methods: Following habituation, force and time data were collected for all four limbs of seven Labrador Retrievers during sets of five valid trot trials. Each set was performed twice daily (morning and afternoon), every seven days for three consecutive weeks.
To determine whether the canine pelvic limb can be considered a linkage of rigid bodies during kinematic analysis.
Use of commercially available foam pipe insulation as a protective device for wounds over the elbow joint area in five dogs.
Case Description-4 large-breed dogs were referred because of nonhealing skin wounds involving the elbow joint area of several weeks to months in duration. One additional large-breed dog was evaluated because of a draining abscess with overlying skin necrosis. Clinical Findings-Previous attempts at closing each wound over the elbow joint area had been unsuccessful. At the time of hospital admission, open wounds had variable degrees of bacterial contamination and infection.
Comparison of temporospatial and kinetic variables of walking in small and large dogs on a pressure-sensing walkway.
Objective-To compare temporospatial variables (TSVs) and kinetic variables (KVs) for fore-limbs and hind limbs of small and large dogs of various breeds during walking and to determine associations among body weight (BW), TSVs, and KVs in these groups. Animals-12 adult dogs with no evidence of lameness. Procedures-Dogs (grouped according to BW as small [< 10 kg; n = 6] or large [> 25 kg; 6]) were walked in a straight line at their preferred velocity on a wooden platform with an embedded pressure-sensing walkway.

Objective: To define the kinematic motion patterns of the canine cervical spine, with a particular emphasis on identifying differences between the cranial (C(2) -C(4) ) and caudal (C(5) -C(7) ) segments, and to determine the significance of coupled motions (CM) in the canine cervical spine. Study Design: Cadaveric biomechanical study. Sample Population: Cervical spines of 8 Foxhounds. Methods: Spinal specimens were considered free of pathology based on radiographic, computed tomography, and magnetic resonance imaging examinations.
