Study summary

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.

Read the detailed description

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

  • Already highly active (>10,000 steps/day, or about 1.5 hours of walking).
  • Participation in competing interventional trials.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Study arms

  • No intervention
    "Passive" Smartwatch arm

    * Smartwatch collects step and wear-time data passively. * Participants do not receive daily goals, structured prompts, or real-time feedback regarding progress. * Nurses provide general advice but do not review detailed step graphs. * Data used only for endpoint assessment at M3.

  • Experimental
    "Active" Smartwatch arm

    * Smartwatch provides real-time structured feedback, including daily step counts, a visual progress bar, and automated prompts. * Research technician review step graphs during tele-visits, highlighting high/low activity days, barriers, and facilitators personalized daily step goals (twice a week) defined as +15-20% above baseline will be adjusted by Research technician based on progress and symptoms. * Goals increased by +10% if ≥4/7 days meet targets; maintained or decreased if symptomatic or not meeting goals.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2026; primary completion for Dec 2027, 15 months later.

Of 3,108 non-industry interventional studies with no phase under Stroke, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 46. This study's planned 15 months is below that.

Counting every sponsor, half of 3,252 studies reached it within 23 months; a quarter within 10 and three quarters within 46.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 10, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
