这工作的主要设想是研究多发性硬化症患者对声刺激的不同的脑干反应。先是每秒给以10次,然后每秒50次。希望弄清在反复刺激时这类病员的异常适应情况。作者对比了35名正常人(30耳)和6例病人的全部相同资料结果。电位用浅表记录,作用电极置于剃发的头皮上(Davis法),相关电极放在刺激侧的耳垂或乳突部,下颏部电极接地。测定电极间阻抗和极性后开始测验。患者戴耳机,另一侧用抗噪声罩。测定听阈
The main idea of this work is to study different brainstem responses to acoustic stimuli in patients with multiple sclerosis. First give 10 times per second, then 50 times per second. Hoping to find out the abnormal adaptation of such patients during repeated stimulation. The authors compared the same data results for 35 normal subjects (30 ears) and 6 patients. Potential was recorded with a superficial electrode, the acting electrode was placed on the shaved scalp (Davis method), the relevant electrode was placed on the stimulating side of the earlobe or mastoid, and the electrode of the chin was grounded. Measure the impedance and polarity between the electrodes and start the test. Patients wear headphones and an anti-noise mask on the other side. Determination of hearing threshold
