International Shoulder Group

Welcome to the webpage of the International Shoulder Group! Here you can find information about our conferences, and resources related to shoulder biomechanics.

Please get in touch on any of our social media channels, or by contacting our board members. 


We have had a change in format for ISG 2021 Activities.

The Deflt organizers have responded to continuing travel difficulties by organizing an 'ISG Cafe' on May 26th at 16:00 CET.

Please check out the description below and complete the form to receive the link for the meeting:

On May 26, 16:00 CET the International Shoulder Group will host his first international on-line “shoulder café”: a series of short meetings in which some of us will present their work.

These cafés are scheduled for a duration of approximately one hour, with ample time for on-line discussion. The first meeting on May26th will be hosted by the TU Delft. The tentative program is as follows:

16:00 welcome by DirkJan Veeger (TU Delft)

16:05 Dr. Ajay Seth (TU Delft): Estimating rotator-cuff muscle strains to guide physical therapy after surgery

16:25 Prof. Sebastian Dendorfer (OTH Regensburg): The influence of modeling parameters in the AnyBody Modeling System on muscle and joint loading in the shoulder

16:45 Dr. Kathleen MacLean (Dalhousie University, Nova Scotia): Computational Modeling for Exploring the Evolutionary Development of Rotator Cuff Pathology


Short Bio Ajay Seth: Ajay Seth is an assistant professor of Biomechanical engineering at Delft University of Technology. His research centers on neuromuscular and musculoskeletal modeling and computer simulation to understand and quantify human movement. Previously, he was the principal architect of the biomechanical modeling and simulation software, OpenSim--the most widely used musculoskeletal simulator--developed at Stanford University. Ajay's background is in biomechanical modeling, simulation and control (Ph.D.); multibody dynamics and computer simulation (M.A.Sc), and software design and systems engineering (B.A.Sc). He has a decade of industrial software engineering experience and over a dozen years of scientific research and development. Dr. Seth is devoted to applying physics-based modeling and simulations to better measure and classify human performance and to design clinical interventions.

Short Bio Sebastian Dendorfer: Sebastian Dendorfer has studied Civil Engineering and Computational Mechanics in Regensburg and Munich. He got his PhD (Dr.-Ing.) from the University of Paderborn, Germany for his thesis on the deformation and fatigue behavior of cancellous bone. After working with AnyBody Technology in Denmark he returned to Regensburg. Since 2011 he is Professor for Biomechanics at the Technical University of Applied Sciences Regensburg (OTH). He is program coordinator for the Bachelor and Master programs in Biomedical Engineering. His research group focuses on the development of musculoskeletal models, the influence of mental stress on the human body and applications in orthopedics and sports.

Short Bio Kathleen MacLean: Kathleen Maclean completed her Ph.D. in Kinesiology, specializing in shoulder biomechanics, from the University of Waterloo, under the supervision of Clark Dickerson. She is currently a post-doctoral fellow at Dalhousie University in the School of Health and Human Performance, performing clinical and comparative shoulder biomechanics research.

What is ISG

The International Shoulder Group (ISG) is a collaboration of mostly biomechanically oriented research groups, whose main interest is in the shoulder. The ISG has been a Technical Group of the International Society of Biomechanics since 1999. The ISG aims to enhance shoulder research by creating a platform for discussion and the exchange of information, software and data.
