Smartwatch-Guided Secondary Prevention After Stroke

After a first stroke or transient ischemic attack (TIA), the risk of recurrence is high in the weeks and months following the initial event. There are several modifiable risk factors that can reduce this risk, such as blood pressure, diet, physical activity, and smoking. Many stroke patients (NIHSS \< 5) have a low daily step count during the early recovery period, despite a good functional prognosis. Active smartwatches provide real-time feedback, track progress, and set personalized walking goals, thereby boosting motivation and adherence to physical activity recommendations. The combination of advice provided by nurses and active behavioral coaching supported by a smartwatch, compared to passive monitoring, could significantly increase daily step counts over a 12-week period. The results of this research will help guide future large-scale secondary prevention strategies integrating digital health and structured nursing support.
