About this study

Official title: Integrating AI in Stroke Neurorehabilitation (AISN)

The AISN multicenter randomized controlled trial will assess the effectiveness of a novel artificial intelligence (AI)-based clinical decision-support system integrated into the Rehabilitation Gaming System (RGS) for home-based post-stroke rehabilitation. Approximately 192 participants ≥6 months post-stroke will be recruited across several European centers and assigned to one of three groups: RGS with AI decision support, RGS without AI, or standard care. The primary outcome is upper limb motor improvement for stroke patients, with secondary measures including cognitive function, independence, quality of life, usability, cost-effectiveness, and AI-based support performance.

Read the detailed description

The AISN study addresses the gap in long-term, personalized stroke rehabilitation after hospital discharge by evaluating an enhanced digital therapy platform that combines the clinically validated Rehabilitation Gaming System (RGS) with a newly developed AI-based decision-support module. This AI component analyzes patient performance data to provide clinicians with diagnostic and prognostic insights, along with tailored exercise prescriptions.

The trial's key innovation is the formal validation of the AI module in real-world clinical settings, assessing its concordance with clinician decisions, predictive accuracy, and contribution to patient outcomes.

Participants will be randomized into three groups:

RGS+AI: Home-based RGS therapy with AI-driven recommendations for clinicians. RGS-AI: Home-based RGS therapy without AI support. Control: Standard rehabilitation care. The intervention phase will last 12 weeks, with daily home training for experimental groups, and follow-up at 20 weeks. In addition to standard clinical endpoints, the study will include predefined AI validation metrics, focusing on its potential as a certified medical device tool for scalable, personalized rehabilitation delivery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AI-personalized virtual reality rehabilitation system for unsupervised home-based stroke therapyDevice

    The personalized RGS app rehabilitation is a home-based, virtual reality therapy platform for motor and cognitive stroke recovery. Therapy tasks are gamified, task-specific, and adapt in difficulty based on real-time performance. An AI-driven clinical decision support system personalizes and updates exercise prescriptions after each session, with optional clinician adjustments. Integrated wearable sensors (RGSwear) track real-world activity and adherence. Data are securely uploaded to a cloud-based platform for remote monitoring. This is the first multicenter, international RCT to test AI-personalized VR rehabilitation at home with up to 12-month follow-up, combined with cost-effectiveness and usability evaluation.

Study groups in NCT07138495
Study groupRoleWhat they receive
RGS with AI-based Clinical Decision SupportExperimentalParticipants receive home-based virtual reality rehabilitation using the Rehabilitation Gaming System (RGS@home), with exercise prescriptions personalized by an AI-driven clinical decision support system. Clinicians can review and adjust these prescriptions remotely.

Control Group - Standard CareNo interventionParticipants receive usual post-stroke rehabilitation services available at their site, without access to the RGS@home platform.

  2. Disability evaluation

    Assessment of global disability with the Modified Ranking Scale - mRS

    Measured: From enrollment to the end of treatment at 12 weeks, and follow-up at 20 weeks

  3. Emotional change

    Assessed with the Hamilton Depression Scale

    Measured: From enrollment to the end of treatment at 12 weeks, and follow-up at 20 weeks

  4. Quality of life and Health status

    Assessed with EQ-5D-5L questionnaire

    Measured: From enrollment to the end of treatment at 12 weeks, and follow-up at 20 weeks

  5. Therapists' qualitative evaluation of the AI-based decision support system performance

    Usability (standardized questionnaire on usage, credibility, and time consumption) Cost efficiency (between the two experimental groups RGS+AI/-AI, time spent for making the prescription, technical support, patient visits during therapy) RGS +AI/-AI performance (pre- and post-treatment values of diagnostics, prognostics, recommendations, and deviations

    Measured: At the end of the study, at 20 weeks.
