Study population: The study group (post-stroke) consisted of 26 patients (mean age 54.9±7.1) in whom ischaemic stroke occurred within 14 days before the admission to the Clinical Department. The control group was composed of 26 healthy (mean age 55.6±6.1) individuals recruited from the hospital staff who did not experience stroke.
Inclusion criteria to the post-stroke group were as follows :
- occurrence of hemiparesis after the first episode of ischaemic stroke
- stroke confirmed in the diagnostic imaging records
- score >3 on Lovett's scale of muscle strength in the paretic limbs
- score above 15 in Barthel's scale of performance in activities of daily living
- score below 12 in the National Institutes of Health Stroke Scale (NIHSS)
- available complete medical records concerning the assessed risk factors of recurrent CVD event
- lack of concomitant pulmonary diseases including chronic obstructive pulmonary disease and bronchial asthma
Exclusion criteria from the post-stroke group were as follows:
- hemiparesis or tetraparesis following many episodes of stroke,
- lack of diagnostic imaging scans confirming the occurrence of stroke
- hospital stay at the Department of Neurological Rehabilitation for more than 14 days from the occurrence of stroke
- incomplete medical records concerning the assessed risk factors of recurrent CVD event
- score >3 on Lovett's scale of muscle strength in the paretic limbs
- score below 14 in Barthel's scale of performance in activities of daily living
- score above 13 in the NIHSS scale
- occurrence of factors limiting walking ability, such as diagnosed pulmonary diseases, unstable angina, severe valvular heart diseases, cardiomyopathy, musculoskeletal or autoimmune diseases.

About this study
Official title: The Use of Samsung Health and ECG M-Trace Base II Applications for the Assessment of Exercise Tolerance as the Secondary Prevention in Patients After Brain Stroke
The aim of the present study was to quantitatively assess the risk factors that may affect the re-occurrence of a CVD event and the use of a commercially available mobile application Samsung Health for the assessment of parameters of exercise tolerance and the ECG M-Trace Base II application for the assessment of cardiological parameters.
Read the detailed description
In the post-stroke group and in the control group, SMWT (Six Minute Walk Test) and SCT( Stair Climb Test) were preceded by a 10-minute rest in sitting position. The time of test performance, the walked distance and steps made as well as the mean and maximum gait velocity and the calories burned were assessed using the above-mentioned Samsung Health application . ECG results were assessed with the use of ECG M-Trace Base II application described above. In addition, cardiological parameters such as: systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate (HR) and arterial blood saturation were assessed. The measurements were performed at rest and directly after SCMT and SCT. Additionally, after the tests, the level of dyspnoea and fatigue was assessed according to the modified Borg scale (score 0-10).

Questions about this trial
What is this clinical trial studying?
An observational study of Mobile Applications and Secondary Prevention, run by Poznan University of Medical Sciences at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
heart rate at rest (time frame: baseline). The study lists 30 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04821518, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Mar 2021; AzTrials last refreshed its copy on 8 Nov 2026.
