Acupuncture is regarded as an effective therapy for cerebral ischemia. Different acupuncture manipulations and durations may result in different therapeutic effects. In the present study, the Neiguan (PC6) acupoint of rats with occluded middle cerebral arteries was needled at a fixed frequency (3 Hz) with different durations, i.e., 5, 60 and 180 seconds under a twisting-rotating acupuncture method. Results showed that different durations of acupuncture had different therapeutic effects, with 60 seconds yielding a better therapeutic effect than the other two groups. This duration of treatment demonstrated rapid cerebral blood flow, encouraging recovery of neurological function, and small cerebral infarct volume. Experimental findings indicated that under 3 Hz frequency, the treatment of needling Neiguan for 60 seconds is effective for ischemic stroke.

针刺被认为是治疗脑缺血的一种有效疗法。不同的针刺手法和时长可能会产生不同的治疗效果。在本研究中，采用捻转针刺法，以固定频率（3赫兹）对大脑中动脉闭塞的大鼠内关穴（PC6）进行针刺，时长分别为5秒、60秒和180秒。结果表明，不同针刺时长具有不同的治疗效果，60秒组的治疗效果优于其他两组。该治疗时长能使脑血流加快，促进神经功能恢复，且脑梗死体积较小。实验结果表明，在3赫兹频率下，针刺内关穴60秒对缺血性中风有效。
