Abstract
Musculoskeletal models of the shoulder are needed to understand the mechanics of overhead motions, but existing models are generic and might not accurately represent an individual’s scapular kinematics. The aim of this work was to develop an approach for personalizing the shoulder rhythm constraints in a computational upper body model to reduce marker tracking errors in the kinematic analysis of shoulder motions.
In the first half of the webinar, Dr. Maier will present her shoulder rhythm personalization approach and the results of her study. She will present how the shoulder rhythm is implemented in the generic model and how it can be personalized with the help of five calibration measurements.
In the second half of the webinar, Dr. Maier will give a tutorial explaining how to use the personalization approach for your own data. Using colab notebooks and OpenSim she will guide the audience through the step-by-step process of model scaling and model personalization.

Jennifer Maier
postdoctoral scholar
Dr. Jennifer Maier is a postdoctoral scholar in Mechanical Engineering at Stanford University working with Professors Scott Delp and Ellen Kuhl in the Digital Athlete Project of the Wu Tsai Human Performance Alliance. She received her PhD from the Friedrich-Alexander-University Erlangen-Nürnberg (FAU). Her thesis was awarded the Elsbeth Wendler-Kalsch Promotionspreis, a Doctoral Thesis Award awarded by the Faculty of Engineering of FAU. Dr. Maier is passionate about research in the healthcare and performance sector to enable all individuals to achieve their optimal health and well-being. Her current research focuses on studying the shoulder biomechanics of overhead athletes, like baseball pitchers and volleyball hitters, to understand what factors lead to peak performance and a lower risk of injuries.
