Effekten av traktkil på det distala benets rörelsemönster hos travhäst :

Changing of the hoof angle is a common method for the treatment of many lameness-related conditions (Moyer 1980; Stashak 2002). Various studies in the literature have indicated different results of the effect of changing the hoof angle on the movement of the distal limb. Our study investigated the effect of raising the heel of the forelimbs by 10,7 mm on the movement of the distal limb. Horses trotted on a treadmill at several predetermined speeds. The Kinematics of the distal limb was determined and variables including the extension of the fetlock joint were determined.

Arbetsprov i fält på ridhästar

Sport horses are widely used for performance in jumping, dressage, endurance etc. To enable comparisons of horses, training facilities, programs or physical status, an exercise test can be used. Exercise tests are also important to increase knowledge about exercise physiology of the horse considering different ways of training to compare training methods or individual qualities, development of an individual or other investigations of equine exercise physiology. Since several investigations are done on standard- and thoroughbred horses but less on sport horses, it is of great importance to get an overview of the investigations done. Most common is to investigate heart rate and lactate concentration.

Kinematics methodology and simulation in Catia v5

Denna rapport är ett examensarbete på 7.5hp för CAD-tekniker på Högskolan i Halmstad.Gruppen har fått i uppdrag från företaget National Gummi AB i Trönninge att ta fram en upprullare för stora gummiprofiler. Personalen rullar ner gummiprofilerna i en lastpall för hand vilket kan slita ut personalens ryggar då gummiprofilerna väger en del..

Lättridningens påverkan på hästens rörelsemönster i trav :

The interest in horses and equestrian sport is constantly increasing, and so is the will in both riders and trainers to learn more about the effect the rider and its equipment have on the horse. The last twenty years, more and more studies have been performed were the horse and its Kinematics have been in focus. The access to more advanced technology has made it possible to study areas, which earlier have been hard to reach. The knowledge about Kinematics in the horse, and how riders and their equipment interact with the horse?s movement, is also of great interest to veterinarians in equine practice.

Tillvänjning av labradorer att skritta och trava på löpband :

The aim of this study was to determine a method to habituate treadmill-naive Labrador Retrievers to walk and trot on a treadmill. 17 Labradors was equipped with reflective markers glued to the skin. Their motions were captured with six 240 Hz infra-red cameras as they walked and trotted on a treadmill three times a day for two days. Also the heart-rate was recorded. We then used QTM and custom built software to analyze the measurements.

Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward Kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

Axelrehabilitering med fokus på Serratus Anterior : en systematisk litteraturstudie av EMG-studier

AimThe aim of this study was to, through a systematic literature review of evidence based electromyographic (EMG) studies, identify specific exercises for rehabilitation of the Serratus Anterior muscle. The research questions were: ?Which exercises can be recommended to use to activate the Serratus Anterior?? and ?Are the recommended exercises altered between studies on individuals with and without shoulder dysfunction??. MethodThe method was a systematic literature review. First the study aim and research questions were formulated. A research protocol was then formulated with inclusion and exclusion criteria and search terms.

Objektiv rörelseanalys : ett stöd vid den visuella bedömningen av hälta hos hund?

Lame dogs are a common group of patients for the practicing veterinarian. In the literature it is described how a clinical examination can be performed, based on general clinical-, orthopedic- and neurological examination, and visual evaluation of the dog when standing and during motion. For research, objective gait analysis systems are also used to study clinically healthy and lame dogs during motion. The aim of this degree project was to compare objective kinematic gait analysis with a visual evaluation of dogs with different types of lameness. The project was a pilot study to show if objective gait analysis could be used as a support for the visual examination. Ten lame dogs of different breeds and with different diagnoses were included in the study. They were all patients at the University Animal hospital, Uppsala.

The movement of the rider?s hand related to the horse?s behaviour and the stride cycle

One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).
