Last thursday Simon Gross successfully defended his doctoral thesis on the influence of fatigue on musculoskeletal loading. In his work he investigated fatigue of single muscles as well as muscle groups and implemented an novel fatigue algorithm which can be used for musculoskeletal analyses.
We had a number of contributions to the 2019 European Society of Biomechanics Meeting in Vienna:
Simon Auer presented his preliminary study on the influence of mental stress on muscle forces in football players and could show that stress in fact increases forces and might therefore play an important role in the develpment of injuries.
Maximilian Aurbach showed his study on how different modelling parameters influence shoulder joint reaction forces. He proposed that the use of Hill-type muscle models might play the most important role in proper force prediction of inverse dynamic models.
Franz Süß work was present by Sebastian Dendorfer. Again a stress topic, this study could show how cognitive stress increases spinal forces even under very controlled motion.
Simone Kubowitsch studied the influence of cognitive stress on biomechanical symmetry in spinal muscles and could show significant differences in muscle recruitement under stress.
Maximilian Melzners development and validation of a novel musculoskelettal hand model was presented by our partners on University Ulm. The new model has quite some potential to adress biomechanical questions on the hand.
All studies were recieved quite well and it will be exciting to see these projects go on!

Thanks to the organizers for the great conference.
In cooperation with our partners at the Department of Orthopaedic Surgery, Regensburg University Medical Centre we got a paper accepted in Scientific Reports. The main author is Florian Völlner, he reports about in vívo measurement for ligament stiffness which is an important parameter in knee endoprosthesis surgeries.

We will present parts of our work this summer at the European Society of Biomechanics Congress in Vienna, where we will have 5 podium presentations from our lab and at CMBBE in New York with presentation and poster. More details will follow.
Thanks to all participants in the 2019 musculoskeletal modeling workshop. It was a pleasure having you in our university. With participants from 8 countries it was once again a great opportunity to see old and make new friends.
The workshop covered basic intro to modeling, hand-on and details on recent shoulder modeling activities.
Am 12.04. findet wieder Nacht Schafft Wissen statt. Das Labor für Biomechanik ist von 18:00-23:00 für Besucher offen. Wir freuen uns auf tolle Diskussionen. Der Vortrag “Es muss auch mal wehtun – die Biomechanik des Älterwerdens” findet um 21:00 im Raum D002 statt. Für die Kinder haben wir wieder Roboter vorbereitet, die durch Muskelkraft gesteuert werden können (18:00 – 20:00, Dauer etwa 10-20 Minuten). Unser Labor ist umgezogen: Der neue Raum ist C101!
The Interdisciplinary Shoulder Symposium is the conclusion of a free4-day Beginner Workshop (04.03.2019-07.03.2019) on Musculoskeletal Modelling, hosted by the Laboratory for Biomechanics of the OTH Regensburg.
Congratulations to our long time team member Michael Putzer who had his successful doctoral examination last Thursday. The titel of his thesis: Development of subject-specific musculoskeletal models for studies of lumbar loading.
In his work he developed models in the AnyBody Modeling System and could show how anatomical and mechanical parameters influence biomechanical results. Furthermore, he studied the influence of intervertebral disc herniation on lumbar loading.
The thesis was handed in to the Universität der Bundeswehr München. His examers where Prof. Ingo Ehrlich and Prof. Norbert Gebbeken.
We will once again organize a Musculoskeletal Modeling Workshop using the AnyBody Modeling System.
The course will include a review and discussion of important theoretic background, but emphasis will be on practical skills to perform musculoskeletal simulations with the AnyBody Modeling System. The course will span several areas of musculoskeletal simulation from medical device development to ergonomics, sport performance, general biomechanics and academic/clinical research.
