Patients with long-term cognitive impairments following COVID-19 face significant challenges in their rehabilitation, which involves essential therapeutic procedures, administrative tasks, diagnostic tests, and self-assessments. "Digiphysical" methods, combining digital and physical healthcare interventions, offer promising solutions to enhance these rehabilitation processes. In this paper, we present a newly developed digital rehabilitation prototype based on the digiphysical approach. The prototype is designed to integrate digital and physical interventions, streamline clinical and administrative tasks, support the entire rehabilitation process, and facilitate self-directed rehabilitation. It addresses the rehabilitation needs from both the patients' and the rehabilitation personnel's perspectives. In this paper, we present the results of an initial evaluation of the prototype conducted with key rehabilitation professionals.
