Summary

The human-device interaction group advances regulatory science through the study of human interaction with existing and emerging medical device technologies. Our overarching goal is to improve therapeutic, diagnostic, and rehabilitative outcomes for patients. In addition to applications to neurology, physical medicine, orthopedics, and surgery, the lab is equipped to address cognitive and other human factors that influence device usability across therapeutic areas.

Available instrumentation includes an extensive array of leading edge equipment for monitoring and modeling medical devices and human users, including 3D-printing capabilities, motion and ground force capture technologies, computational modeling and simulation tools, and muscle monitoring (electromyogram), brain monitoring (electroencephalogram), and eye-tracking systems.

Optical markers are used to track and quantify movements in space.

Current project areas include:

• Test method development for next-generation upper limb prosthetics
• Sex-specific modeling and analysis of ACL injury susceptibility
• Assessment of patient views on risks and benefits of innovative prosthetic technologies
• Human factors evaluation of 3D-printed patient-matched surgical instrumentation
• Real-world data collection for larger, smarter, distributed clinical trials
• Population variability of EEG biomarkers with potential diagnostic utility

We are continually seeking collaborations with other medical device stakeholders, including clinicians, academic researchers, technology developers, and our colleagues at the FDA and the National Institutes of Health.
