Coortes e Intervenções
Grupo / Coorte |
---|
Physical Fitness
Patients from this group underwent 4 weeks of aerobic fitness training additional to normal supportive care, 5 times a week, for 50 minutes
|
Relaxation
Patients of this group received 4-weeks of relaxation sessions additional to normal supportive care, 5 times a week, for 50 minutes.

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
---|---|---|
Cerebral perfusion
Prazo: baseline and 4-weeks
|
Magnetic resonance imaging (MRI)-based cerebral perfusion are assessed before and after the 4-weeks of physical fitness training. Primary and secondary endpoints are specified after completion of the interim analysis after inclusion of the first 24 patients (first stage). In a second stage the study is conducted with specified primary and secondary endpoints with recruitment of up to 76 remaining patients. |
baseline and 4-weeks
|
Blood-derived biomarkers
Prazo: baseline and 4-weeks
|
Changes in blood biomarkers are assessed before and after the 4-weeks intervention of physical fitness training. Primary and secondary endpoints are specified after completion of the interim analysis after inclusion of the first 24 patients (first stage). In a second stage the study is conducted with specified primary and secondary endpoints with recruitment of up to 76 remaining patients. |

Medidas de resultados secundários
Medida de resultado |
Descrição da medida |
Prazo |
---|---|---|
next cerebrovascular event
Prazo: 6 months
|
Patients re-admitting hospital with suspected transient ischemic attack (TIA), stroke, or other cerebrovascular event within 6 months post stroke
|
6 months
|
functional outcome
Prazo: directly after the end of intervention and 3 months post stroke
|
functional outcome assessed via functional scores such as Barthel Index and walking speed (co-primary endpoints of PHYS-STROKE) as well as the modified Rankin Scale (mRS)
|
directly after the end of intervention and 3 months post stroke

Outras medidas de resultado
Medida de resultado |
Descrição da medida |
Prazo |
---|---|---|
functional outcome
Prazo: 3 months
|
Analyzing how changes in imaging measures and blood-derived biomarkers are related to each other and to differences in functional outcome, in particular gait speed, Barthel index (co-primary endpoints of PHYS-STROKE) and modified Rankin Scale
|
3 months
|
endothelial function assessment
Prazo: measurement before and after the 4 weeks intervention
|
the endothelial function of included patients will be assessed prospectively before and after the 4 week intervention with the Endopat2000 device.
First measurement was conducted in January 11th 2014.
Results will be correlated with imaging and blood-derived biomarkers as well as differences between intervention groups.
|
measurement before and after the 4 weeks intervention
|
Clinical biomarkers including vital Parameters
Prazo: measurements at baseline and all follow-up time points (measurement before and after the 4 weeks intervention, at 3 months and at 6 months after stroke)
|
systolic and diastolic blood pressure, resting heart rate, body-mass-index, and waist-to-hip-ratio over time compared between study groups
|
measurements at baseline and all follow-up time points (measurement before and after the 4 weeks intervention, at 3 months and at 6 months after stroke)
