Evaluate the reproducibility of Forling, a portable instrument for measuring axial tongue force.
Axial force of the tongue was measured in 49 individuals (30 women and 19 men) aged 18-25 years using the Forling portable instrument. Measurements were performed in three days at intervals of 7±2 days. On each day, three 7-second measurements were performed with one-minute intervals between them. The coefficient of variation, Wilcoxon paired test, and intraclass correlation coefficient were used in the statistical analysis of the data. Maximum and mean tongue force values were analyzed, and comparison between them was performed using three approaches: the mean of the three values; the mean of the two highest values; the highest value of each measurement.
In the analysis of mean tongue force, the coefficient of variation was considered desirable and the intraclass correlation coefficient was acceptable. Significant differences were observed regarding the maximum value between the second and third days, mean of the two highest values and mean of the three values between the first and second days and the second and third days. In the analysis of maximum tongue force, the coefficient of variation and the intraclass correlation coefficient were acceptable. Significant difference was found only in the comparison between the second and third days.
Good reproducibility of the data obtained with the use of the Forling portable instrument was observed.
评估用于测量舌轴向力的便携式仪器Forling的可重复性。
使用Forling便携式仪器对49名年龄在18 - 25岁的个体（30名女性和19名男性）测量舌轴向力。测量在三天内进行，间隔为7±2天。每天进行三次7秒的测量，每次测量间隔一分钟。变异系数、Wilcoxon配对检验和组内相关系数用于数据的统计分析。分析了最大和平均舌力值，并使用三种方法对它们进行比较：三个值的平均值；两个最高值的平均值；每次测量的最高值。
在平均舌力分析中，变异系数被认为是理想的，组内相关系数是可接受的。在第二天和第三天之间的最大值、第一天和第二天以及第二天和第三天之间的两个最高值的平均值和三个值的平均值方面观察到显著差异。在最大舌力分析中，变异系数和组内相关系数是可接受的。仅在第二天和第三天的比较中发现显著差异。
观察到使用Forling便携式仪器获得的数据具有良好的可重复性。
