Effect of Starting Distance on Vertical Ground Reaction
EFFECT OF STARTING DISTANCE ON VERTICAL GROUND REACTION FORCES IN THE DOG by DAVID BURNETT DULANEY (Under Direction the of Hugh Dookwah) ABSTRACT Kinetic gait analysis is used extensively in both human and veterinary medicine, both to detect pathological gait abnormalities and to quantify the efficacy of surgical and pharmacological protocols. This study evaluates the effect of three different staring distances from the kinetic data collection device (2m, 4m, and 6m) on the peak vertical and associated impulse ground reaction forces generated by the test subjects at a trot. Five dogs weighing between 20 and 30kg were trotted over two force plates at between 1.6 and 2.1 m/s until 5 right first contacts and 5 left first contacts were collected. Data collection was repeated approximately a week apart for a total of 5 collections. Vertical impulse values were found to be significantly different (p<0.05) between 2m and 6m, but neither were different from 4m. Peak vertical force was not found to be significantly effected by distance.

Irish Water Spaniel
YOU BE THE JUDGE By Robert Cole From Dogs in Canada, May 2005 THE IRISH WATER SPANIEL HISTORY According to Harry Glover, author of The Standard Guide to Pure- Bred Dogs, there’s little doubt that the Irish Water Spaniel owes its origins to the European Water Dog (Figure 1), which he informs us was also an ancestor of the Poodle. This woodcut is from the 4,000-page Icons Animatium produced by Conrad Gessner over the period 1551-57. For the book General History of Quadrupeds, Thomas Bewick (1752-1828) produced a woodcut of the Large Rough Water Dog (Figure 2), which is closer in appearance to today’s Irish Water Spaniel than Conrad Gessner’s woodcut. This woodcut also resembles the Otterhound, a breed said to be an IWS ancestor (in addition to the Portuguese Water Dog and a setter or two). The Irish standard (FCI) informs us that the exact origins of the breed remain obscure. Generally it is thought that water spaniels evolved from dogs that originated in Persia and came to Ireland via Spain. The first Irish reference to water dogs that pursue waterfowl dates from 1600, so we know that dogs with waterproof coats were used in Ireland even before the advent of the flowing piece. There is no real evidence of the ancestry of the Irish Water Spaniel except in its most peculiar feature, the rat tail. This feature appears in no similar dog and makes it very likely that the modern breed had an indigenous Irish ancestor. The tail has given rise to the names “Whit Tail” and “Rat Tail”. -

Normal and Abnormal Gaits in Dogs
Pagina 1 di 12 Normal And Abnormal Gait Chapter 91 David M. Nunamaker, Peter D. Blauner z Methods of Gait Analysis z The Normal Gaits of the Dog z Effects of Conformation on Locomotion z Clinical Examination of the Locomotor System z Neurologic Conditions Associated With Abnormal Gait z Gait Abnormalities Associated With Joint Problems z References Methods of Gait Analysis Normal locomotion of the dog involves proper functioning of every organ system in the body, up to 99% of the skeletal muscles, and most of the bony structures.(1-75) Coordination of these functioning parts represents the poorly understood phenomenon referred to as gait. The veterinary literature is interspersed with only a few reports addressing primarily this system. Although gait relates closely to orthopaedics, it is often not included in orthopaedic training programs or orthopaedic textbooks. The current problem of gait analysis in humans and dogs is the inability of the study of gait to relate significantly to clinical situations. Hundreds of papers are included in the literature describing gait in humans, but up to this point there has been little success in organizing the reams of data into a useful diagnostic or therapeutic regime. Studies on human and animal locomotion commonly involve the measurement and analysis of the following: Temporal characteristics Electromyographic signals Kinematics of limb segments Kinetics of the foot-floor and joint resultants The analyses of the latter two types of measurements require the collection and reduction of voluminous amounts of data, but the lack of a rapid method of processing this data in real time has precluded the use of gait analysis as a routine clinical tool, particularly in animals. -

Thesis Kinematic and Kinetic Analysis of Canine Thoracic
THESIS KINEMATIC AND KINETIC ANALYSIS OF CANINE THORACIC LIMB AMPUTEES AT A TROT Submitted by Sarah Jarvis Graduate Degree Program in Bioengineering In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Fall 2011 Master’s Committee: Advisor: Raoul Reiser Deanna Worley Kevin Haussler ABSTRACT KINEMATIC AND KINETIC ANALYSIS OF CANINE THORACIC LIMB AMPUTEES AT A TROT Most dogs appear to adapt well to the removal of a thoracic limb, but clinically there is a particular subset of dogs that still have problems with gait that seem to be unrelated to age, weight, or breed. The purpose of this study was to objectively characterize biomechanical changes in gait associated with amputation of a thoracic limb. Sixteen amputees and 24 control dogs of various breeds with similar stature and mass greater than 14 kg were recruited and participated in the study. Dogs were trotted across three in-series force platforms as spatial kinematic and ground reaction force data were recorded during the stance phase. Ground reaction forces, impulses, and stance durations were computed as well as stance widths, stride lengths, limb and spinal joint angles. Kinetic results show that thoracic limb amputees have increased stance times and vertical impulses. The remaining thoracic limb and pelvic limb ipsilateral to the side of amputation compensate for the loss of braking, and the ipsilateral pelvic limb also compensates the most for the loss of propulsion. The carpus, and ipsilateral hip and stifle joints are more flexed during stance, and the T1, T13, and L7 joints experience significant differences in spinal motion in both the sagittal and horizontal planes throughout the gait cycle stance phases. -
Use of a Collar-Mounted Triaxial Accelerometer to Predict Speed and Gait in Dogs
animals Article Use of a Collar-Mounted Triaxial Accelerometer to Predict Speed and Gait in Dogs Samantha Bolton, Nick Cave *, Naomi Cogger and G. R. Colborne School of Veterinary Science, Massey University, Palmerston North 4442, New Zealand; [email protected] (S.B.); [email protected] (N.C.); [email protected] (G.R.C.) * Correspondence: [email protected]; Tel.: +64-6-3505329 Simple Summary: Accelerometers have been used for several years to monitor activity in free- moving dogs. The technique has particular utility for measuring the efficacy of treatments for osteoarthritis when changes to movement need to be monitored over extended periods. While collar- mounted accelerometer measures are precise, they are difficult to express in widely understood terms, such as gait or speed. This study aimed to determine whether measurements from a collar-mounted accelerometer made while a dog was on a treadmill could be converted to an estimate of speed or gait. We found that gait could be separated into two categories—walking and faster than walking (i.e., trot or canter)—but we could not further separate the non-walking gaits. Speed could be estimated but was inaccurate when speed exceeded 3 m/s. We conclude that collar-mounted accelerometers only allowing limited categorisation of activity are still of value for monitoring activity in dogs. Abstract: Accelerometry has been used to measure treatment efficacy in dogs with osteoarthritis, although interpretation is difficult. Simplification of the output into speed or gait categories could simplify interpretation. We aimed to determine whether collar-mounted accelerometry could estimate the speed and categorise dogs’ gait on a treadmill. -

Evaluation of Pacing As an Indicator of Musculoskeletal Pathology in Dogs
Vol. 8(12), pp. 207-213, December 2016 DOI: 10.5897/JVMAH2016.0512 Article Number: 62D6B3B61551 Journal of Veterinary Medicine and ISSN 2141-2529 Copyright © 2016 Animal Health Author(s) retain the copyright of this article http://www.academicjournals.org/JVMAH Full Length Research Paper Evaluation of pacing as an indicator of musculoskeletal pathology in dogs Theresa M. Wendland, Kyle W. Martin, Colleen G. Duncan, Angela J. Marolf and Felix M. Duerr* Department of Clinical Sciences, Colorado State University, United States. Received 4 August, 2016: Accepted 13 October, 2016 Little is currently known about the pacing gait in dogs and it has been speculated that pacing may be utilized by dogs with musculoskeletal pathology. The goals of the present study were to determine if pacing in dogs is associated with musculoskeletal disease and to establish if controlled speed impacts pacing. Dogs underwent orthopedic and lameness assessments. Musculoskeletal pathology, when identified, was further defined with radiography of the affected area. Dogs were considered musculoskeletally normal (MSN) if no pathology was detected and they had no history of musculoskeletal disease. All others were considered musculoskeletally abnormal (MSA). Animals were then evaluated for pacing using digital-video-imaging under three conditions: Off-lead, lead-controlled, and on a treadmill. Thirty-nine dogs were enrolled (MSN: n = 20; MSA: n = 19). Overall, pacing was observed more frequently in dogs under lead-controlled than off-lead conditions (P < 0.001). Lead- controlled MSN dogs were observed to pace significantly more frequently (n = 17/20) than lead- controlled MSA dogs (n = 10/19; P = 0.029). -
