本文对41例小脑疾病患者进行了姿势描记术，通过测力平台，用计算机在线程序计算了患者的摇摆路径、摇摆面积、前后和侧向摇摆分量以及视觉稳定量。对8例脊髓性共济失调（Friedreich's）患者、6例前庭-小脑病变患者、11例前叶萎缩患者、7例半球性小脑病变患者和9例小脑各部位病变患者的姿势性共济失调进行了定量研究。小脑半球病变的患者不能通过姿势图与正常人分开。脊髓-小脑传入神经病变（弗里德赖希共济失调）引起全方位低频摆动，视觉稳定性得以保留。前叶萎缩的患者表现出明显的前后摆动，通常伴有约3 Hz的自发性高频身体震颤。前庭-小脑病变表现为全方位低频摆动，视觉稳定性差。定量姿势描记术有助于定位小脑病变，并允许定量随访研究小脑疾病。
Posturography was performed in 41 patients with cerebellar diseases by means of a force measuring platform using an on-line computer program which calculated sway path, sway area, antero-posterior and lateral sway components and the amount of visual stabilization. Postural ataxia was quantitatively studied in 8 patients with spinal ataxia (Friedreich''s), 6 patients with vestibulo-cerebellar lesions, 11 patients with anterior lobe atrophy, 7 patients with hemispheral cerebellar lesions and 9 patients with a disease affecting all parts of the cerebellum. Patients with lesions of the cerebellar hemispheres could not be separated from normals by means of posturography. Lesions of the spino-cerebellar afferents (Friedreich''s ataxia) caused an omnidirectional low frequency sway with preserved visual stabilization. Patients with anterior lobe atrophy showed a predominant antero-posterior sway, often with a spontaneous high frequency body tremor around 3 Hz. Vestibulo-cerebellar lesions exhibited omnidirectional low frequency sway poorly stabilized by vision. Quantitative posturography helps to localize cerebellar lesions and allows for quantitative follow-up studies of cerebellar diseases.
