声门下压（Ps）、发声阈压（PTP）和喉阻力（LR）可以作为声带疾病的指标。金标准的非侵入性测量使用唇中断，这已被证明具有可靠性不一致性。机械中断方法在测量可靠性方面表现出了良好的前景。本研究的目的是比较唇部中断法和机械中断法的重测可靠性。55名年龄在18-69岁之间的受试者参与了研究。每种方法共进行10次试验。对于唇部中断，受试者以舒适和安静的音量产生五个唇部爆破音。对于机械中断，受试者产生持续的/α/，而球囊阀中断发声5次。30名受试者在第一次访问后大约两周（15天±3.76天）完成了与第一次相同的第二次研究访问。测定每位受试者的Ps、PTP、平均气流速率（MFR）和LR，并分析每位受试者的重测信度。机械中断和唇部中断对复测结果的差异百分比分别为12.88%±10.15和27.56%±17.14 （p = 0.0003）。机械PTP测量的百分比差异为21.46%±16.01，唇部测量的百分比差异为17.04%±14.62 （p = 0.3372）。力学Ps的受试者内变异系数为0.086±0.046，唇部Ps的受试者内变异系数为0.161±0.078 （p < 0.0001）。机械性PTP系数为0.177±0.083，唇部PTP系数为0.186±0.091 （p = 0.5402）。最后，对于LR (Ps除以MFR)，机械组的百分比差异为14.33%±10.06，唇部组的百分比差异为53.87%±43.19 (p < 0.0001)，受试者内部差异为0.115±0.050，唇部组为0.287±0.222 （p < 0.0001）。使用机械中断测量的Ps和LR在单独研究访问和受试者内部变异性的重新测试中显示出更高的一致性。PTP在重测和受试者内部变异性方面相似。继续改进机械中断技术是必要的，因为这些方法比唇部中断方法提供更高的可靠性和一致性。
Measures of subglottal pressure (Ps), phonation threshold pressure (PTP), and laryngeal resistance (LR) can be used as indicators of vocal cord disorders. The gold standard non-invasive measurement uses labial interruption, which has been shown to have reliability inconsistencies. Mechanical interruption methods have demonstrated promise in measurement reliability. The goal of the present study is to compare retest reliability of labial and mechanical interruption methods. 55 subjects aged 18–69 participated. 10 trials were performed for each method. For labial interruption, subjects produced five labial plosives at comfortable and quiet volumes. For mechanical interruption, subjects produced a sustained /α/ while a balloon valve interrupted phonation five times. 30 subjects completed a second study visit identical to the first approximately two weeks (15 days ± 3.76) after the first visit. Ps, PTP, mean airflow rate (MFR), and LR were determined for each subject and retest reliability for each was analyzed. The percent difference in measurement results for test-retest of Ps were 12.88% ± 10.15 for mechanical interruption and 27.56% ± 17.14 for labial interruption (p = 0.0003). The percent difference for PTP measurements were 21.46% ± 16.01 for mechanical and 17.04% ± 14.62 (p = 0.3372) for labial. Intra-subject coefficients of variation of Ps were 0.086 ± 0.046 for mechanical and 0.161 ± 0.078 for labial (p < 0.0001). For PTP, the coefficients were 0.177 ± 0.083 for mechanical and 0.186 ± 0.091 for labial (p = 0.5402). Lastly, for LR (Ps divided by MFR) the percent differences were 14.33% ± 10.06 for mechanical and 53.87% ± 43.19 for labial (p < 0.0001) with intra-subject variability of 0.115 ± 0.050 for mechanical and 0.287 ± 0.222 for labial (p < 0.0001). Ps and LR measured using mechanical interruption showed more consistency for both retesting across separate study visits and intra-subject variability. PTP was similar in retesting and intra-subject variability. Continued work to improve mechanical interruption techniques is warranted as these methods offer higher reliability and consistency than the labial interruption methods.
