Webinar: A Novel Scapulothoracic Joint Model Improves the Accuracy of Measured Shoulder Movements

Learn about the development, validation, and applications for a new scapulothoracic joint model


A recording of the event is available for viewing. You can learn more about the model through its project page and publication, listed below. A half-day workshop is also being offered during the annual meeting of the International Shoulder Group July 14-16, 2016 in Switzerland.


Title:A Novel Scapulothoracic Joint Model Improves the Accuracy of Measured Shoulder Movements
Speakers: Ajay Seth (Stanford University) and Ricardo Matias (University of Lisbon)
Time: Thursday, June 9, 2016 at 9:30 a.m. Pacific Standard Time


The movement of the scapula under soft tissue makes it difficult to measure, reconstruct and study shoulder movements. Even when movements may appear to be reasonable, the standard set of (Euler) angles that describe the scapula orientation with respect to the clavicle (or torso) are challenging to interpret and compare across tasks and individuals. We recently developed a model of the scapulothoracic joint in a multibody skeletal model that improves the accuracy of noisy measurements captured in the lab or at the clinic, and further, provides kinematics that are easier to interpret, explain and compare. In this webinar, we will explain the unique approach we took to model the scapulothoracic joint. We will also describe how we evaluated the accuracy of the model against bone-pin data and tested its robustness across thousands of trials with added systematic noise. Finally, we will demonstrate the applicability of the model by examining an activity of daily living.
