MINT100

Our lab participated in MINT100. We conducted a workshop on the use of artificial intelligence with musculoskeletal modeling for the development of preventive measures. In the end we had a tool which could estimate spinal loading for different ways of lifting weights based on neural network analyses. The participants were students from different German high schools.

Publication in Computer Methods in Biomechanics and Biomedical Engineering

Maximilian Melzners work on the impact of anatomical uncertainties on the prediction of musculoskeletal hand model has been published in the journal Computer Methods in Biomechanics and Biomedical Engineering. The work investigates how sensitive our models react on anatomical variations. This is one of the major uncertainities when we work with generic models. The results are quite promising. It seems our hand model is stable for many configurations and thus can be used in further research. You can find the whole article (open access) here.

Thank to RCBE for supporting the open access option.

Paper in Journal of Orthopedic Research published

Another piece of our research with the Orthopedics Department of the University Regensburg on total hip arthoplasty has been published in Journal of Orthopedic Research. Markus Weber is the main author of the study. The title of the work is: Kinematic pelvic tilt during gait alters functional cup position in total hip arthroplasty. It features detailed analyses of data on 60 patients with a follow up time of 12 month. The complex kinematics in hip replacements are of great importance for a safe and long lasting treatment.

Webcast on the use of motion analysis and EMG

Simone who is close affiliatied with the laboratory of biomechanics has been appointed as Professor at Hochschule Augsburg. Simone Kubowtisch has worked with us on the influence of stress on the musculoskeletal system and for sure we will continue this work. Congratulation.

Paper in Frontiers Psychology accepted

Clara Scheers work on muscle activations due to emotions has been accpted for publication in Frontiers Psychology. Her work was done in cooperation with LBM. The title of the paper is: Happy Enough to Relax? – How positive and negative emotions activate different muscular regions in the back – An explorative study. Co Autors are: Simone Kubowitsch, Sebastian Dendorfer and Petra Jansen.

Paper on the influence of mental stress on football players accepted.

Simon Auers work on mental stress in football players has been accepted for publication in “Science and Medicine in Football”. The full title ist: Mental stress reduces performance and changes musculoskeletal loading in football related movements. The paper features experiments on football players which were artificially stressed and analyses changes in kinematics and musculoskeletal loading which was computed using inverse dynamics. Co Autors to the paper are: Simone Kubowitsch, Franz Süß, Tobias Renkawitz (Department of Orthopaedics and Trauma Surgery, Heidelberg University Hospital), Werner Krutsch (Department of Trauma Surgery, Regensburg University Medical Center), Sebastian Dendorfer

Webcast on hand modeling

Maximilian Melzner will present his work on hand modeling which is part of the EU funded projekt (EFRE Ziel ETZ, BY-CZ) Geburtshilfe 2.0 in an online seminar.

 

Musculoskeletal research questions regarding the prevention or rehabilitation of the hand can be addressed using inverse dynamics simulations. To date, no complete human hand model implemented in a holistic human body model has been fully developed. Hence, the aim of this work was to develop, implement, and validate a fully detailed hand model using the AnyBody Modeling System.
Sign up for the presentation by Lucas Engelhardt, Researcher at the Scientific Computing Centre Ulm, Germany and Maximilian Melzner, Research Assistant at the Ostbayerische Technische Hochschule Regensburg, Germany.

Dr. Maximilian Aurbach

Erfolgreiche Promotion in der Biomechanik

Mit der erfolgreichen Verteidigung am 12.11.2020 hat Herr Dr. Maxmilian Aurbach seine Promotion im Bereich Biomechanik abgeschlossen. Die Promotion in den Humanwissenschaften (Dr. sc. hum.) wurde von der Universität Regensburg vergeben und von Prof. Dr.-Ing. Sebastian Dendorfer (Labor für Biomechanik, Fakultät Maschinenbau) betreut. Als externe Gutachter konnten für die Arbeit Herr Prof. Dr. Tobias Renkawitz von der Universitätsklinik für Orthopädie und Unfallchirurgie Heidelberg sowie Herr Prof. Dr. John Rasmussen der Universität Aalborg, Dänemark gewonnen werden.

In seiner Arbeit hat Herr Dr. Aurbach virtuelle Menschmodelle entwickelt, welche in den Bereichen Orthopädie und Ergonomie eingesetzt werden. Die Studie war größtenteils in das EU geförderte Projekt „Virtuelle Menschmodelle für die Prävention, Therapie und Rehabilitation von Schulterverletzungen“ (EFRE Bayern 2013-2020, Ziel ETZ CZ-BY) eingebunden. Die Hauptergebnisse der Promotion wurden auch bereit in hochkarätigen Journals publiziert sowie auf mehreren internationalen Kongressen vorgestellt.

Webcast on the influence of mental demand on leg loading for football players.

Simon Auer will give a webcast about parts of this PhD work. The webcasts will be given in cooperation with AnyBody Technology on the 29th of September. Details can be found here.

Football players have a high risk of leg muscle injuries, especially when exposed to mental stress. Injuries to muscles of the thigh are common in amateur and professional football, representing almost a third of all injuries. These injuries occur primarily in non-contact situations and from overuse. They can lead to a range of costs, including financial costs associated with treatment as well as those associated with long-term recovery, and absence from training and/or competition. Further, there is a high risk of injury recurrence and subsequent injury.
Musculoskeletal models are an established method for analyzing internal body loads in ergonomic or rehabilitation. In the recent past, these models have also been used for more dynamic movements such as those found in soccer. Hence, we investigate the effects of mental stress in highly dynamic motion. This will provide new information on internal loading of the lower extremities and help to prevent injuries.
