目的测定与分析眩晕患者的前庭眼反射与前庭脊髓反射功能. 方法用眼震电图描记法(ENG)和姿势描记法(PSG)测定40例健康者和82例眩晕患者的眼震电图和姿势描记图及有关参数. 结果眩晕患者ENG检查记录到13例自发性眼震,55例位置性眼震;半规管功能正常36例,减退27例,麻痹19例;视动中枢检查无异常. PSG检查正常人重心移动轨迹以中心型为主,眩晕患者弥散型多见. 健康者与眩晕患者各参数相比较,眩晕患者轨迹长,面积大,速度快,差异显著. 结论应用ENG和PSG可对前庭眼反射和前庭脊髓反射功能作定量分析,可靠性、客观性强,对眩晕症的鉴别诊断有实用价值.
AIM To examine and analyse the vestibular eye reflex and vestibular spinal reflex function of vertigo patients. METHODS The electronystagmogram, posturogram and related parameters of 40 normal subjects and 82 patients suffering from vertigoes were measured with electronystagmography (ENG) and posturography (PSG). RESULTS Of 82 vertigo patients ENG examination, showed 13 cases of spontaneous nystagmus and 55 cases of positional nystagmus, 36 cases of normal, 27 cases of decline and 19 cases of paralysis of semicircular canals function and normal optokinetic center functions, PSG examination showed that the centripetal pattern of postural sway was the most prominent in the normal subjects, but the diffuse pattern in the vertigo patients. The locus length, velocity and area of postural sway of the vertigo patients were increased significantly as compared with that of normal subjects. CONCLUSION Quantitative analysis of the vestibular eye reflex and vestibular spinal reflex function can be reliably and objectively realized with ENG and PSG. They are valuable methods in the differential diagnosis of vertigoes.
