Letter to the Editor - Update from Ukraine: Rehabilitation and Research.

This Letter to the Editor provides an update on the research from the Glushkov Institute of Cybernetics of the National Academy of Sciences of Ukraine. The Institute's clinical research team is currently rehabilitating the military personnel of the Defense Forces of Ukraine with combat stress reaction and post-traumatic stress disorder using hybrid e-rehabilitation methods and techniques. Current research in the field of digital health and IoMT in Ukraine is creating innovative information technology for computerized electrocardiography. The conduct of rehabilitation and research in an active war zone with safety concerns, limited resources for research, and intermittent loss of power and water is very challenging.
