用磁刺激评定皮质脊髓径为近年来的重要进展,因其方便、无痛而优于电刺激。本研究对中风患者及与其年龄、性别、体重相当的健康人各41例,以磁刺激大脑皮层运动区和下段颈区,在对侧拇短展肌检测皮层和颈区运动诱发电位(MEPs)。与健康人比,中风患者皮层MEPs 的振幅和潜伏时、中枢传导时间(CCT)及两侧CCT 间的差(DCCT)均有显
Magnetic stimulation to assess the corticospinal diameter is an important advance in recent years, because of its convenience, painless and better than electrical stimulation. In this study, 41 stroke patients and 41 healthy subjects with similar age, sex and weight were enrolled in this study. The cortical and cervical motor evoked potentials (MEPs) were detected by magnetic stimulation of the motor cortex and lower cervical region. . Compared with healthy controls, the amplitude and latency of MEPs in stroke patients, central conduction time (CCT) and the difference between two CCTs (DCCT) were significantly
