Although combined glottography has potential as a clinical tool, it has had limited use in the monitoring of laryngeal function before and after treatment. There is no data about the standardization nor reproducibility of the procedure. An indication of the reproducibility of combined glottography is paramount if changes in laryngeal function are to be measured accurately. Using a standardized technique, two complimentary studies examined the reproducibility of combined glottography within one sitting (Study 1) and over time (Study 2). The components of variance were analysed (ANOVA). In Study 1 the variance under controlled conditions for Open Quotient (OQ) and Speed Quotient (SQ) was only 13% and 18% respectively of the total, whilst in Study 2 the variance over time for OQ and SQ was 55% and 58% respectively. Under controlled conditions combined glottography is a reproducible technique.
尽管联合声门图法有作为临床工具的潜力，但它在治疗前后喉功能监测中的应用有限。关于该检查方法的标准化和可重复性尚无数据。如果要准确测量喉功能的变化，联合声门图法可重复性的指标至关重要。采用标准化技术，两项补充研究分别在一次检查期间（研究1）和不同时间（研究2）检测联合声门图法的可重复性。分析了方差成分（方差分析）。在研究1中，开放商数（OQ）和速度商数（SQ）在受控条件下的方差分别仅占总量的13%和18%，而在研究2中，OQ和SQ随时间变化的方差分别为55%和58%。在受控条件下，联合声门图法是一种可重复的检查方法。
