The ability to accurately measure tibiofemoral angles during various dynamic activities is of clinical interest. The purpose of this study was to determine if inertial measurement units (IMUs) can provide accurate and reliable angle estimates during dynamic actions. A tuned quaternion conversion (TQC) method tuned to dynamics actions was used to calculate Euler angles based on IMU data and these calculated angles were compared to a motion capture system (our “gold” standard) and a commercially available sensor fusion algorithm. Nine healthy athletes were in-strumented with APDM Opal IMUs and asked to perform nine dynamic actions; five participants were used in training the parameters of the TQC method with the remaining four used to test validity.

The survey questions were organized in the following categories:
- demographics: age, gender identity, race, ethnicity, and country of birth
- education: degree type and date earned, STEM area
- employment field, employer information, title, job duties
- measures of productivity including research, grant, patents and site/workplace/lab access
- work/life balance: responsibilities and duties
Questions regarding productivity and work/life balance queried pre and post COVID experiences. Many questions solicited optional comments and the relevant ones are presented as a table.
