大量研究证实卒中后病人电刺激体感诱发电位(SEP)与深感觉损害有关。近来应用CO_2激光刺激器记录与痛觉相关的诱发电位,对周围神经病变者可客观地反映痛觉损害程度,并与痛觉损害程度有较好的相关性。本文作者对12例(男7例,女5例,平均年龄67.5岁)经颅脑CT或MRI证实患有脑梗塞或脑出血病人的痛觉相关SEPs和电刺激SEPs与卒中病变部位的相关性进行了对照研究。检查在卒中1个月后进
Numerous studies have demonstrated that electrical stimulation of somatosensory evoked potential (SEP) in patients after stroke is associated with profound sensory impairment. Recently, CO_2 laser stimulator was used to record the pain-evoked potentials, which can objectively reflect the degree of pain impairment in patients with peripheral neuropathy and have a good correlation with the degree of pain damage. The authors of this study evaluated the association of pain-related SEPs and electrically stimulated SEPs with stroke lesions in 12 patients (7 males and 5 females with an average age of 67.5 years) confirmed by brain CT or MRI on patients with cerebral infarction or intracerebral hemorrhage The control study.
