Our Presentation at the World Congress of Physical and Rehabilitation Medicine (ISPRM)

Loreen Pogrzeba

I present the current research "Application of Computer-Assisted Neutral Zero Method of the Shoulder Joint in Vojta Therapy" at the 9th World Congress of the ISPRM (International Society of Physical and Rehabilitation Medicine) on Saturday, the 20th of June, as part of the poster session from 12:45 to 14:45 in the afternoon at the Maritim Hotel in Berlin. You are cordially invited!


In November 2012 I've met Heidi Orth from the International Vojta Society (IVG) at the 10th Symposium of the German Association for Music Physiology and Musicians' Medicine (DGfMM) in Dresden. We both took part in a workshop about motion analysis and started talking about the technical requirements and possibilities of motion recording technology. We stayed in touch and together with her colleague Barbara Maurer-Burkhard and Mark Schramm, a student of Media Computer Science at the HTW Dresden, we've developed a measurement protocol and software to record and analyze the motion of patients with diseases and restricted mobility at the shoulder joints. Our protocol follows the assessment of range-of-motion (ROM) measurements and facilitates insights into the specific execution of motion exercises and the archieved maximum ROM at the shoulder joints. In addition, these measurements enable analysis of the short-term effect of the Vojta therapy and could allow future insights into long-term effects if the measurements are conducted parallel to the rehabilitation process. The research ist part of the PhD project Motion Analysis in Rehabilitation and Sports Medicine.

Our presentation at the ICMPC 13 - APSCOM 5 next week in South Korea

Loreen Pogrzeba

I will present a scientific paper on the ICMPC 13 - APSCOM 5 in South Korea next week. This is the story on how this came about. Click here to go straight to the abstract ...


In the end of 2010 I’ve met the music therapist Minea Alvsten and was fascinated by the FMT therapy approach. As I heard later, functional music therapy (FMT) is a non-verbal active music therapy, which is focused on the neuropsychological development of patients, evaluated by the observation of the patients' motor skills. The therapist uses music as a tool to communicate with the individually treated person, and to motivate the person emotionally to perceive, react, move, play, and interact.


This description opens up many questions: How does the therapist “communicate” with the patient without using words? What does he do during therapy? And what is he looking for, so what defines improvements of the “patient’s motor skills’”?


As a former student in media computer science and current PhD student in motion analysis I have a special interest in this bodily improvements and how I could record, measure, analyze and visualize them. That’s why I went to Sweden for half a year in summer 2012. I’ve lived in Eskilstuna, 100 km from Stockholm, and worked at the FMT Behandlingscenter Eskilstuna. Together with Margareta and Karina I’ve recorded the motion of 20 patients (10 with Stroke, 10 with Parkinson’s disease) for later analysis. I’ve attended lessons in FMT at the Musikhögskolan Ingesund, 260 km from Stockholm, and learnt Swedish. And I spoke to many inspiring and interesting FMT therapists or just listened to them, e. g. to all the future therapists in Ingesund, to Margareta and Karina, Anita Granberg, Salome Persson, Ulla Sterner, Mikael Walldin, Gunnar Smideman, Lars Persson, Sol-Britt Häggblom, and Jennie Karf. Many thanks to all of you, for your time and effort!


In the course of all these conversations I got an understanding to which motion skills FMT therapist pay attention. And we’ve learned to understand each other, the different ways of thinking, expressing ideas, “therapeutic” and “technical” language. Thus Margareta Ericsson and Karina Larsson from the FMT Behandlingscenter, my doctor supervisors Markus Wacker and Bernhard Jung, and I wrote a scientific paper about how to analyze FMT from both the perspectives of a computer scientist and a FMT therapist. We created a kind of 3d motion data vocabulary which is meaningful, understandable, comprehensible and objectively measurable for our two different working disciplines.


In one week I will have the honor to present our scientific paper at the 13th International Conference on Music Perception and Cognition and the 5th Conference for the Asia-Pacific Society for Cognitive Sciences of Music in Seoul, South Korea.


You are cordially invited to listen to my talk on how to analyze FMT using a 3D motion data vocabulary on Friday, the 8th of August in session 9B “Music Therapy: Rhythm and Motor” from 10 to 10:30 am at the Yonsei University in Seoul, South Korea. Here you can find the abstract. Feel free to contact me to discuss your questions and ideas, perhaps during lunch or just anywhere at the conference. I am highly looking forward to get to know you.


This talk is just one further step to develop a computer-assisted analysis software for FMT. If you cannot be on location and are curious for more information just send me an e-mail with your questions or visit my PhD website with further information!

Character Modelling Workshop at HTW Dresden, 10th/11th Apr

Sebastian Gassel
Dear 3d artists and animators! We invite you to dive in deeper in the art of character modelling! In the course of this 2-day-workshop with Tanja Krampfert - Modeller and Character TD at Pixar - the participants will be guided through the process of modelling a previously designed character from the concept phase to the final model in the context of animation. This includes both the conception of a character design and the correkt approach and compliance of certain Do's and Don'ts during the modeling process which in turn are a prerequisite to achieve a correct deformation in character animation. When? April 10th and 11th, 1.30 to 6.30 PM Where? At HTW Dresden (University of Applied Science) Software available?Autodesk Maya, 3D Studio Max, Blender Requirements Prior knowledge in 3D modelling techniques and experience in at least of the above listed modelling tools Preparation Please bring a character draft including sketches in perspective, front and side view. Language German/English (depending on participants) Costs 15 EUR attendence fee for the complete workshop (to be paid in advance) The number of participants is limited. In order to sign up for this workshop, please fill out the registration form until April 3rd. We hope to see you soon at HTW Dresden!

Markerless Motion-Capturing Workshop at HTW Dresden

Sebastian Gassel
Dear 3d animators and film makers! We invite you to explore the diversity of human movement in general and of walking styles specifically. In this 4-hour hands-on workshop you will get the possibility to capture and explore unique ways of walking. We will introduce you to the mocap workflow: - capturing the movements with our markerless motion-capture system - tipps and tricks of cleaning and smoothing motion data in Autodesk’s Motion Builder software - and transferring the motion to various characters for export to other animation packages. The 4-hour workshop will take place at University of Applied Sciences Dresden near main station and will be given on request. If you’re interested in participating and you have basic experience in 3D animation software, please let us know via email to sstrauss[at*]informatik.htw-dresden.de (limited number of participants) to fix a date and time. Where? At HTW Dresden (University of Applied Science) When? On request (- Please email sstrauss[at*]informatik.htw-dresden.de for further information! -) Software used:Autodesk Maya, Autodesk Motionbuilder Requirements: Prior knowledge in any 3D animation package preferable, but not necessary Language: English or German (depending of participants) Costs: Free Apart from this workshop, please note the yearly DREMATRIX promotion prize (Submission deadline: June 1st) promoting new ideas of visualizating movement and/or solid concepts of integrating motion capture in the artistic film making process. The price includes - two full days of motion capture in our system with a technical support team & - 500 € for travel expenses and hotel costs. Send us your sketch, a short vita and some references until June 1st, 2014!
