Thirty-nine patients aged 21-82 years (mean 62 years) under investigation for suspected acquired hydrocephalus were investigated by dynamic posturography before and 6-8 h after a cerebrospinal fluid tap of 20-40 ml. Dynamic posturography comprises a sensory organization (SO) part in which the platform and visual surround are either stable or referenced to the patient's sway. The eyes are closed or open. In a movement coordination (MC) part the platform makes active movements, thus introducing external disturbances in the procedure. The patients improved their balancing ability in all tests on the sway referenced platform in SO, while MC remained unaffected. It is concluded that dynamic posturography is valuable for dysequilibrium assessment in clinical evaluation of suitable candidates for ventricular shunts in acquired hydrocephalus.
39名年龄在21至82岁（平均62岁）之间、因疑似获得性脑积水而接受检查的患者，在进行20至40毫升脑脊液穿刺前及穿刺后6至8小时接受了动态姿势描记法检查。动态姿势描记法包括一个感觉组织（SO）部分，其中平台和视觉环境要么稳定，要么参考患者的摇摆情况。眼睛闭合或睁开。在运动协调（MC）部分，平台进行主动运动，从而在检查过程中引入外部干扰。在SO中，患者在所有关于参考摇摆平台的测试中平衡能力均有提高，而MC未受影响。得出的结论是，动态姿势描记法在对获得性脑积水脑室分流术合适候选者的临床评估中，对失衡评估具有重要价值。
