对24名健康志愿者进行了姿势图测量的指导性和可重复性研究。在一次教学中，研究了“稳定”(倒立摆模型)和“放松”(分段振荡模型)位置。此外，还考察了习惯化适应的影响和日变化。分析了振动摄动姿态时的摇摆速度、平均位移和最大位移。在个体回答中，没有观察到统计上显著的逐日差异，个体差异很小。在“松弛”状态下，当分析最大位移时，失稳程度更大。摇摆速度和平均位移没有明显变化。结果表明，正常的姿势控制机构具有显著的稳定性。
The effect of instruction and repeatability of posturography measurement was studied in 24 healthy volunteers. In an instruction, "stable" (inverted pendular model) and "relaxed" (segmental oscillating model) positions were studied. In addition, the effect of habituation adaptation, and day-to-day variation were investigated. Sway velocity and average and maximum displacement during vibration perturbated stance were analysed. In individual responses, no statistically significant day-to-day variation could be observed and the individual variation was small. In the "relaxed" condition, the instability was greater when maximum displacement was analysed. No significant changes in sway velocity and average displacement were observed. The results demonstrated remarkable stability of normal postural control mechanism.
