Inget ingripande: Control group
The participants received r-tPA thrombolytic therapy after diagnosed ischemic stroke.
In addition, all participants receive a standard clinical therapy.
|
|
|
Experimentell: RIC group
The upper limb ischemic conditioning is composed of five cycles of upper limb ischemia intervened by reperfusion, which is induced by two cuff placed around the upper arms respectively and inflated to 200 mm Hg for 5 minutes followed by 5 minutes of reperfusion by cuff deflation.
This therapy started within 2 hours after r-tPA thrombolytic therapy.
In addition, all participants receive a standard clinical therapy.

In this study, the remote ischemic conditioning treatment was composed of five cycles of bilateral upper limb ischemia intervened by reperfusion, which was induced by two cuff placed around the upper arms respectively and inflated to 200 mm Hg for 5 minutes followed by 5 minutes of reperfusion by cuff deflation.
