AI-Powered brain games and exercise may revitalize stroke survivors

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Completed the endpoint assessment of the preceding CEEEC Phase I trial (NCT06975501) and remains under management at a participating community health service station in Kunshan. * Age 60 years or older. * Hospital-confirmed ischemic or hemorrhagic stroke in a stable stage, with no new or worsening neurological deficit within the previous 3 months. * Registered hypertension and/or type 2 diabetes mellitus; other comorbid conditions are permitted. * Willing and able to participate in the 12-week community-based extension program and complete baseline and endpoint assessments. * Able to travel to the community site independently or with a cane or walker; not dependent on a wheelchair for attendance. * Short Physical Performance Battery total score \>=3, or able to maintain a supported side-by-side standing position for 10 seconds when the total score is \<3. * Able to communicate in Mandarin Chinese or the Kunshan dialect and able to recognize Arabic numerals. * Corrected vision sufficient to identify large characters at approximately 40 cm and at least one upper limb able to complete touchscreen selection. * Resides in the participating community and has no plan to move away during the study period. * Provides written informed consent specifically for CEEEC-II. Exclusion Criteria: * Life-threatening disease or another condition associated with an expected survival of less than 6 months. * A new stroke, transient ischemic attack, acute coronary event, or hospitalization for decompensated heart failure within the previous 3 months. * Uncontrolled resting blood pressure (systolic \>=180 mmHg or diastolic \>=110 mmHg after repeated measurement) until clinically reassessed and controlled. * Extreme glycemic instability, including fasting blood glucose \>16.7 mmol/L or severe hypoglycemia requiring assistance within the previous month, until clinically reassessed. * An absolute contraindication to unsupervised community exercise or another medical condition judged by the study clinician to make participation unsafe. * Unable to walk to the community site even with a cane or walker, or dependent on a wheelchair for attendance. * A severe musculoskeletal, neurological, visual, hearing, cognitive, psychiatric, or communication impairment that prevents safe participation or valid completion of study procedures. * Unable to recognize Arabic numerals or unable to complete touchscreen selection with either upper limb. * Current participation in another structured physical, cognitive, or nutrition intervention study that may contaminate the assigned intervention. * Any other reason documented by the study clinician as making the individual unsuitable for participation.
