Seminar met Professor Dr. Dr. h.c. Martin Fischer. Friedrich Schiller University Jena, Institute for Zoology and Evolutionary Research with Phyletic Museum, Ernst Haeckel House and Biology.
We feliciteren Professor Fischer met het in april 2018 toegekende eredoctoraat uitgereikt door de  Justus-Liebig-Universität Gießen in het vakgebied diergeneeskunde. Een compliment voor zijn levenswerk.

Op zaterdag wordt het dogs in motion onderzoek behandeld en zondag gaan we dieper in op de materie, zoals toepassingen en nieuw (anatomisch) inzicht in operaties en medicatie. Dit seminar is uitermate geschikt voor dierenartsen gezelschapsdieren.

There are still many misunderstandings about the movement of dogs. Not only among dog owners, but also among professionals such as veterinarians, orthopaedic specialists and behavioural experts. The previous time 1 day turned out to be very short to handle the comprehensive research. That is why it was decided to divide the seminar over 2 days this time. On Saturday the topic is the dogs in motion research and on Sunday we will go deeper into the subject matter, such as applications and new insights into (knee)surgery and medication. Looking at bones, joints or muscles, their function is not necessarily clear from their form. MARTIN S. FISCHER’s overarching research interest has always been the integration of form and function and the function of motion. In this video, he explains how locomotion, how animals and humans move, influences all locomotor operators. To examine the function of form the researchers need to study form during motion. For this, they use fluoroscopy (high-speed X-rays), EMG’s of muscles and observe the overall behavior of the experimental subject. This gives them the opportunity to study the three-dimensional function of limbs. They have had numerous findings, among them the mismatch of the terminology of human muscles applied to dogs; another one concerns the reason for the zigzag shape of birds’ legs. Their findings have multiple implications, for instance in the development of treatments in veterinary medicine.

 

With the world’s largest study on the movement of dogs to date, we have investigated the question of what effect the breeding choice had on the movement of the various dog breeds, especially considering, for example, that there is a fortyfold difference in weight between Chihuahua or dachshund and Great Dane.

Or do the dogs, regardless of their breed, move largely the same way? The focus of the first Jena studies on the locomotion of dogs was therefore the question of similarities and differences in the locomotion of different dog breeds. For this purpose, gait analyses of 327 dogs were carried out. It should be emphasised that in addition to the German Research Foundation (DFG), breed associations and the “Society for Cynological Research” (GKF), considerable financial contributions were made. The German Kennel Club (VDH) also supported the study and made the book “Dogs in Motion” (Fischer & Lilje 2011) possible.

Three different techniques were used to record locomotion: high-frequency videography, marker-based motion analysis (Qualisysâ) and high-frequency biplanar X-ray videography. We have been conducting the “Heel Study on Joint Dynamics” since 2014. For the first time, the three-dimensional motion sequences of the limbs in walking and trotting are measured with elaborate technology and the so-called inverse dynamics are calculated. The latter allows the performance in a joint to be recognized and the calculated work of muscles to be compared with electromyographic data. For the first time, the three-dimensional kinematics of five different dog breeds will also be investigated.

First results are presented and previously unrecognized movements in the knee or shoulder joint show how the body structure affects limb movement. In 2015 the book “Lameness investigation in dogs” by Daniel Koch and Martin S. Fischer was published. In the lecture, findings from this collaboration between the well-known Swiss veterinarian and a functional morphologist will be presented. fundamentals 1.)

Our study proves the extensive agreement in the locomotion of 32 dog breeds and even of Great Danes or dachshunds in the parasagittal leg guidance. This means that from the side all examined dogs show a largely identical movement pattern. The differences between ten dogs of the same breed are almost always greater than the mean values between the breeds. 2.)

Locomotion is not always generated by muscle work. Depending on the gait, energy is recovered in different ways from gravity-induced movement of the body’s centre of gravity. In order to be able to use such vertical movements of the body’s centre of gravity in a controlled manner, the legs must swing in unison, i.e. work with the same stride lengths and stride frequencies. This is only given in the symmetrical gaits (walk, pass and trot). The energy-saving mechanisms function most efficiently during cyclical locomotion. Manoeuvres such as acceleration, braking or even a change of direction and jumping are only possible with additional muscle work. 3.)

The mechanisms of the dog’s movement are therefore essentially aimed at minimising energy consumption and using gravity intelligently to save energy. Smooth, cyclical locomotion does not require complex control and great brain performance, but rather intelligent mechanics. This can compensate for disturbances caused by uneven terrain, for example. Technical literature has introduced the term “no-brainer” (Daley, 2008). 4.)

The “work” in locomotion is unevenly distributed between the front and hind limbs. When walking and trotting, even the braking forces predominate at the front. During the even, cyclical locomotion, the propulsion mainly comes from the hind limbs and here mainly from the hip joint. The pivot point of the front limbs is at the same height as the hip joint in the upper third of the shoulder blade. Around this moving pivot point, guided only by muscle power, the shoulder blade and thus the entire anterior ligament are moved.
