Our ESR14-Alessandro Bonfiglio- and his supervisors published a manuscript two weeks ago abou the effects of Different Inertial Measurement Unit Sensor-to-Segment Calibrations on Clinical 3-Dimensional Humerothoracic Joint Angles Estimation.
In their paper, they focus on the humerothoracic joint among all joints involved in the shoulder complex aiming to compare and validate 3 calibration methods to estimate its 3D angles from raw IMU orientation data during a variety of movement tasks. Their goals were to (1) assess accuracy and precision of each calibration against an optical motion capture system and (2) compare the 3 calibration methods against one another to provide recommendations on the most optimal shoulder joint IMU calibration. Their results showed that the use of a static N-pose calibration procedure is recommended as the preferred IMU calibration method to model the humerothoracic joint, as this setup is the simplest as it only requires accurate positioning of the trunk sensor.
