In clinical practice, we often encounter family members of stroke patients or themselves asking: When is the best time to start rehabilitation after a stroke? The Chinese Guidelines for the Prevention and Treatment of Cerebrovascular Diseases suggest that rehabilitation should be started as early as possible. When is “early” depends on the difference between cerebral ischemia and cerebral hemorrhage. Patients with cerebral ischemia can start rehabilitation after 48 hours as long as they are clear, their vital signs are stable (body temperature, respiration, pulse and blood pressure are normal) and their condition is no longer developing, and the amount of rehabilitation starts from small to large and progresses gradually. Most brain hemorrhage rehabilitation can be started 10 to 14 days after the disease. Although rehabilitation is advocated the earlier the better, patients and family members are often still apprehensive about early treatment, especially patients with cerebral hemorrhage, who are worried that early activity will cause rebleeding; some patients with other organ pathologies such as hypertension and coronary artery disease are worried that treatment will cause blood pressure fluctuations and heart attacks. In fact, patients with cerebral hemorrhage undergo rehabilitation, as long as the blood pressure is stable and the movement is not violent, it will not cause rebleeding, and the rehabilitation treatment starts too late to lose the role of preventing sequelae and complications. Rehabilitation exercises are gradual, and as long as overexertion and excessive force are avoided, blood pressure fluctuations and heart attacks will not occur. Therefore, we advocate “early rehabilitation”, as long as the general vital signs (temperature, respiration, pulse and blood pressure are normal) are stable for more than 48 hours, and there is no contraindication after comprehensive assessment, rehabilitation should be carried out.
