Twenty-eight patients with polyneuropathy aged 49-82 years (mean 67 years) were assessed by dynamic posturography. The patient group was compared to a control group comprising 29 healthy controls aged 70 through 75 years (mean 73 years). The dynamic posturography method comprises a sensory organization part in which the platform and visual surround are either stable or referenced to the patient's sway; furthermore, the eyes are open or closed. In a movement coordination part the platform makes active movements. In the sensory organization part of the dynamic posturography the patient group showed significantly lower equilibrium performance compared to the control group in the test conditions with absent vision, sway-referenced surrounding, and, finally, sway referenced platform and surrounding. In these conditions the influx of somatosensory information is of paramount importance for stable posture. In the movement coordination test, the patient group showed prolonged muscular response latencies in both forward and backward platform perturbations compared to the control group. It is concluded that dynamic posturography is a valuable diagnostic tool in assessment of the dynamic equilibrium performance in patients with polyneuropathy.
对28例年龄在49至82岁（平均67岁）的多发性神经病患者进行了动态姿势描记法评估。将患者组与一个由29名年龄在70至75岁（平均73岁）的健康对照者组成的对照组进行比较。动态姿势描记法包括一个感觉组织部分，其中平台和视觉环境要么稳定，要么参照患者的摇摆；此外，眼睛是睁开还是闭上。在运动协调部分，平台进行主动运动。在动态姿势描记法的感觉组织部分，与对照组相比，患者组在无视觉、摇摆参照环境以及最后摇摆参照平台和环境的测试条件下，平衡表现显著更低。在这些条件下，体感信息的输入对于稳定姿势至关重要。在运动协调测试中，与对照组相比，患者组在平台向前和向后扰动时肌肉反应潜伏期均延长。得出的结论是，动态姿势描记法是评估多发性神经病患者动态平衡表现的一种有价值的诊断工具。
