Exoskeletons, Assistive Technology, Balance Control and Fall Mitigation/Prevention, Biologically-Inspired Control

Dr. Sandra Hnat is an Investigator with the APT Center and the Louis Stokes Cleveland VA Medical Center and a Research Associate in the Department of Biomedical Engineering at Case Western Reserve University School of Medicine. She received her Bachelor of Science in Mechanical Engineering (2013) and Doctor of Engineering (2018) from Cleveland State University. She then completed her postdoctoral training at the APT Center and at Case Western Research University in the Department of Biomedical Engineering and School of Medicine under a NIH T32 Musculoskeletal Health Postdoctoral Training Grant.

Her research focuses on improving powered exoskeleton technology for users with lower-limb paralysis. Dr. Hnat’s projects include developing an electrical stimulation subsystem to interface with commercial exoskeletons to enhance their rehabilitative outcomes, developing balance, fall detection, and injury mitigation controllers for a hybrid exoskeleton for users with spinal cord injury, and combining surface electrical stimulation and an exoskeletal knee to improve walking after stroke.
