Webinar on Characterizing Hyperreflexia and Abnormal Coordination in Post-Stroke Stiff-Knee Gait and More
by Joy P. Ku 28 Feb '20

28 Feb '20

Webinar: Characterizing Hyperreflexia and Abnormal Coordination in Post-Stroke Stiff-Knee Gait March 12, 2020 at 10:00 a.m. Pacific Daylight Time We invite you to join us for a webinar featuring Tunc Akbas from Harvard University. In this webinar, Dr. Akbas will describe an OpenSim-based framework to investigate the neuromuscular mechanisms of abnormal coordination in post-stroke stiff-knee gait. He will discuss their simulation results and also the use of their framework as a template for exoskeletal assistance post-stroke.

The new software enables users to read in inertial measurement unit (IMU) data and compute inverse kinematics based on IMU orientations. This workflow is called OpenSense. For this release, the user is primarily responsible for ensuring proper calibration and registration of the sensors to an appropriate OpenSim model. Future releases will streamline and enhance this process. This is an exciting initial step towards supporting biomechanical analyses with IMUs in OpenSim. We have also fixed several bugs and improved the user experience.

Announcing OpenSim 4.1 with Support for IMU Data
by Jennifer Hicks 10 Feb '20

10 Feb '20

We are pleased to announce OpenSim 4.1 <https://simtk.org/frs/?group_id=91>. The new software enables users to read in inertial measurement unit (IMU) data and compute inverse kinematics based on IMU orientations. This workflow is called OpenSense. This is an exciting initial step towards supporting biomechanical analyses with IMUs in OpenSim. For this release, the user is primarily responsible for ensuring proper calibration and registration of the sensors to an appropriate OpenSim model. In the future, we will add more advanced algorithms for calibration, registration, and drift correction. You can read more about these new capabilities and try an example: OpenSense - Kinematics with IMU Data <https://simtk-confluence.stanford.edu/display/OpenSim/OpenSense+-+Kinematic…> . We have also fixed several bugs and improved the user experience. Read more and learn how to upgrade <https://simtk-confluence.stanford.edu/pages/viewpage.action?pageId=36439186> .
