Personalised Health Motor and Cognitive Assistance System for RehAbilitation (PHRASE)

Stroke-induced motor and cognitive impairments often worsen after hospital discharge due to limited access to rehabilitation, creating a cycle of non-use and functional loss ("rehabilitation in vain"). The PHRASE system aims to counteract this by providing patient-tailored, continuous rehabilitation at home using the Rehabilitation Gaming System (RGS). This integrated approach leverages VR/AR technology, prognostic tools, and data-driven decision-making to improve motor and cognitive function, reduce costs, and enhance patient independence. The study seeks to validate the effectiveness of the PHRASE system, focusing on its impact on motor and cognitive recovery and its use as a diagnostic and prognostic tool. It hypothesizes that combining the RGS application with conventional therapy will lead to better recovery outcomes compared to conventional therapy alone. This randomized clinical trial (RCT) will compare the RGS-based intervention to conventional therapy in stroke patients in Spain and Romania. Participants will undergo a six-week intervention involving daily 20-30-minute RGS sessions. Assessments are at baseline, mid-study (3 weeks), end of study (6 weeks) and follow-up (14 weeks). Data will be collected on motor and cognitive function, quality of life, usability, and patient/therapist experiences. Participants must be stroke survivors (\>3 months post-stroke), aged \>18, with mild to moderate upper-limb impairment (ARAT \<50) and minimal smartphone experience. The RGS-based PHRASE approach offers a scalable, cost-effective solution for continuous rehabilitation, improving patient recovery, quality of life, and reducing healthcare costs. The study aims to validate its clinical validity in real-world settings.
