Intracerebral hemorrhage (ICH) results from the rupture of small vessels damaged by chronic hypertension, amyloid angiopathy or other disease. Currently, ICH has been a devastating type of stroke that lacking effective therapy. Remote ischemic conditioning (RIC), a systematically protective strategy, has been found to have neuroprotective effects by in patients with ischemic stroke. In addition, animal studies show that RIC is safe in ICH model and it could accelerate the absorption of hematoma. In a previous clinical study (RICH-1), RIC have been found to be safe and well-tolerated in patients with ICH. Therefore, the investigators plan to undertake this study to further evaluate the safety and efficacy of RIC in patients with ICH.

The investigators hypothesize that treatment with RIC will accelerate the absorption of hematoma and improve patients' functional outcomes. Results of this study can potentially bring into account new means to improve the outcomes of ICH patients.

Contraindication for remote ischemic conditioning: severe soft tissue injury, fracture, or peripheral vascular disease in the upper limbs
Any condition which, in the judgement of the investigator, might increase the risk to the patient
