Stroke is a leading cause of disability worldwide, with recovery efficacy influenced by factors like adherence to rehabilitation programs. Utilizing health data visualization to increase patient involvement can enhance understanding, promote positive health behaviours, and deepen engagement in their care. In our research, we aimed to design a simple, intuitive, and accessible visualization system for stroke recovery by (1) conducting semi-structured interviews with healthcare providers with expertise in inpatient stroke recovery, (2) designing medium-fidelity visualization prototypes representing stroke recovery, and (3) refining these designs through feedback from evaluations with healthcare providers and patients recovering from stroke. The resulting designs present a comprehensive and centralized overview of patients' rehabilitation progress. The visualization system we designed aims to empower both patients and healthcare providers with a means to offer a more intuitive and interactive approach to understanding, sharing, and discussing rehabilitation results.
