A technique to quantify the tandem Romberg test (posturography) was used to study ten patients with otosclerosis before (series 1), 48 hours after (series 2), and between two to four months after (series 3) a stapedectomy. The results were analyzed by power spectrum analysis and then compared to findings from electronystagmographic testing performed with series 1 and 3. There was no significant change in the electronystagmography (ENG) test findings between series 1 and 3. Posturography, however, demonstrated an uncompensated vestibular pattern in the immediate postoperative period which, after two months, converted to a compensated vestibular pattern. Posturography serves as a useful quantitative test for the study of patients with balance disorders because the procedure supplements rather than complements the ENG. In addition, posturography detects vestibular reflex abnormalities in stapedectomized patients two months afterwards. Other testing modalities have not consistently demonstrated this postoperative vestibular system instability.
采用一种量化串联罗姆伯格试验（姿势描记法）的技术，对10例耳硬化症患者在镫骨切除术之前（第1组）、术后48小时（第2组）以及术后两到四个月之间（第3组）进行了研究。通过功率谱分析对结果进行分析，然后与第1组和第3组进行眼震电图测试的结果进行比较。第1组和第3组之间，眼震电图（ENG）测试结果无显著变化。然而，姿势描记法显示，术后即刻存在未代偿的前庭模式，两个月后转变为代偿的前庭模式。姿势描记法是研究平衡障碍患者的一种有用的定量测试方法，因为该检查是对眼震电图的补充而非辅助。此外，姿势描记法可在镫骨切除术后两个月检测到患者的前庭反射异常。其他测试方式并未始终显示出这种术后前庭系统的不稳定性。
