Our primary goal was to evaluate the effect of stimulus duration on electrogustometry (EGM) thresholds. Additionally, we sought to evaluate any sex-related influences and compare the above results to those of taste strips.
Electrogustometry thresholds of various stimulus durations (0.5, 1.0, 1.5 and 2.0 seconds) were measured in 212 non-smokers (age range: 10-80 years, divided into eight age-groups) without self-reported gustatory impairment. Furthermore, taste strips chemogustometry measurements in 132 participants were performed.

Electrogustometry thresholds and taste strips, duration of EGM stimuli.
Electrogustometry thresholds increased progressively with age and with stimulus duration from 0.5 to 2 seconds. This pattern was consistent in all six anatomic areas, irrespective of sex. In contrast, when using chemogustometry, no age- or sex-related differences were observed.
Electrogustometry-threshold values increase progressively with age and with stimulus duration. Therefore, we recommend documenting stimulus duration in the future EGM recordings as it may significantly affect EGM amplitude threshold values.
我们的主要目标是评估刺激持续时间对电味觉（EGM）阈值的影响。此外，我们还试图评估任何与性别相关的影响，并将上述结果与味觉条进行比较。
在 212 名无吸烟史（年龄范围：10-80 岁，分为八个年龄组）、无自我报告味觉障碍的非吸烟者中，测量了不同刺激持续时间（0.5、1.0、1.5 和 2.0 秒）的电味觉阈值。此外，对 132 名参与者进行了味觉条化学味觉测量。

电味觉阈值和味觉条，EGM 刺激持续时间。
电味觉阈值随年龄和刺激持续时间从 0.5 秒增加到 2 秒而逐渐增加。这种模式在所有六个解剖区域都是一致的，与性别无关。相比之下，使用化学味觉时，未观察到年龄或性别相关的差异。
电味觉阈值随年龄和刺激持续时间的增加而逐渐增加。因此，我们建议在未来的 EGM 记录中记录刺激持续时间，因为它可能会显著影响 EGM 幅度阈值值。
