Smartwatch-Guided Secondary Prevention After Stroke (WATCH-STEP)
WATCH-STEP : Pilot Trial: Smartwatch-Guided Secondary Prevention After Stroke Randomized Trial of Nurse-led Program With Active vs Passive Smartwatch in Minor Stroke. A Randomized Controlled Trial Evaluating a Nurse-led Secondary Prevention and Physical Activity Program Supported by Either an Active Smartwatch (Structured Feedback) or Passive Smartwatch in Patients With Minor 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.

Yksityiskohtainen kuvaus
To meet the study's objectives, 50 patients who have recently suffered a stroke or a transient ischemic attack (TIA) (< 30 days) will be recruited at Brest University Hospital.
Participation in this study will last 12 weeks. It consists of 3 visits, described below:
=> Visit #1: Enrollment (hospital)
Enrollment will take place during a routine hospital visit. The investigator will obtain the patient's written consent. Randomization will then be performed to assign the patient to a group ("active" or "passive" watch).
For all patients ("active" and "passive" watch groups):
- Program led by nurses, conducted as part of routine care following a recent ischemic stroke or TIA (secondary prevention).
- Issuance of a smartwatch and a smartphone
- Data collection (sociodemographic information, medical history, current treatments, risk factors)
- Questionnaires
- Clinical examination, neurological examination, and blood draw.
For patients in the "passive" smartwatch group:
o The smartwatch will collect data passively, without notifications.
For patients in the "active" smartwatch group:
- Setting daily step goals and assessing potential obstacles
Scheduling regular calls (twice a week) for the duration of the study.
- Visit #2: Phone call
For all patients (both "active" and "passive" watch):
- Phone contact to collect data on changes in risk factors and the occurrence of events of interest (stroke, TIA, and cardiovascular events).
Questionnaires
- Visit #3: End of study (hospital)
The end-of-study visit will take place at the hospital during a scheduled routine care appointment:
- Assessment with a nurse as part of the secondary prevention program (routine care)
- Data collection (risk factors)
- Questionnaires
- Clinical examination, neurological examination, and blood draw
- Return of the smartwatch and smartphone
