目的：研究脑梗塞患者日常生活活动能力（ＡＤＬ）与脑血流量（ＣＢＦ）的关系。方法：随机选择６０例脑梗塞患者，发病３天及１个月后分别评定Ｂａｒｔｈｅｌ指标，Ｆｕｇｌ－Ｍｅｙｅｒ肢体运动功能积分，１３３Ｘｅ吸入法测定ＣＢＦ。结果：２次Ｂａｒｔｈｅｌ指数评分差值与大脑平均血流量差值呈正相关，ｒ＝０．７８，Ｐ＜０．０１；亦与病灶及其周围区血流量差值呈正相关，ｒ＝０．９２，Ｐ＜０．０１；Ｆｕｇｌ－Ｍｅｙｅｒ肢体运动功能评分差值与大脑平均血流量差值、病灶及其周围区血流量差值亦呈正相关，ｒ＝０．８９及０．８４，Ｐ＜０．０１。结论：脑血流量的恢复有利于ＡＤＬ、肢体运动功能的恢复。
Objective: To study the relationship between activities of daily living (ADL) and cerebral blood flow (CBF) in patients with cerebral infarction. Methods: Sixty patients with cerebral infarction were randomly selected. Barthel index, Fugl-Meyer limb motor function score and CBF were determined by 133Xe inhalation after 3 days and 1 month respectively. Results: The difference of 2 Barthel index scores was positively correlated with the difference of average cerebral blood flow (r = 0.78, P <0.01), and also positively correlated with the difference of blood flow between the two groups (r = 0.92 , P <0.01; Fugl-Meyer limb movement function score difference and the average cerebral blood flow difference, the lesion and its peripheral blood flow difference was also positively correlated, r = 0.89 and 0.84, P <0 .01. Conclusion: The recovery of cerebral blood flow is beneficial to the recovery of motor function of ADL.
