Objectives
Narrative objectives1
to evaluate the efficacy of an RIC protocol based on recent literature, determined by the mRS score at 90 days after stroke onset, with a good outcome defined according to the severity at enrollment.

Assessment
Primary outcomes
good functional outcome at 3-months after stroke onset, assessed by the mRS, with a target mRS score of 0-1 in the mild group, 0-2 in the moderate group, and 0-3 in the severe group.
Key secondary outcomes
1) the proportion of patients with a good functional outcome (assessed by the mRS) in each group at 3 months after stroke onset; 2) the change in NIHSS scores from before RIC to after RIC; 3) the incidence of major adverse cardiovascular events, aspiration pneumonia, and all-cause mortality after stroke onset; 4) the frequency of adverse RIC-related events; and 5) the proportion of patients with a mRS score of 0-1.

Interventions/Control_1
Intervention group: a manual blood pressure cuff will be placed around the lower leg or thigh of the unaffected side, and blood pressure will be measured while detecting the dorsalis pedis artery using an ultrasonic Doppler blood flow meter. The intervention (RIC) group will receive four cycles of 5 min of blood pressure cuff inflation, followed by 5 min of reperfusion. Cuff inflation in the RIC group will be at 200 mmHg or 50 mmHg above the systolic blood pressure; however, if the patient cannot tolerate this, the cuff pressure may be 180 mmHg. This procedure will be performed once daily after enrollment, for a minimum of 3 days and a maximum of 7 days. Discomfort and pain will be assessed using a visual analog scale (scale range: 1-10, with 0 indicating no pain and 10 indicating maximum pain).
Interventions/Control_2
Control group: a manual blood pressure cuff will be placed around the lower leg or thigh of the unaffected side, and blood pressure will be measured while detecting the dorsalis pedis artery using an ultrasonic Doppler blood flow meter.
The control group will only undergo blood pressure measurements before and after the intervention period (the 40 mins required for four cycles of RIC).
