本研究的目的是调查的可靠性舌头和握力和耐力测量健康成人使用爱荷华州口腔性能仪器。51名健康受试者（21名男性，30名女性;年龄范围= 19-57岁）进行了测试，在四个场合，间隔1周，以确定重测信度。主要的结果测量是等长的舌头和手的力量（三个试验中最好的）和持续的等长耐力。在第1周和第2周之间，观察到前舌强度（1.7%）和后舌强度（2.5%）以及握力（5%）的小幅增加（组平均值的变化），在随后的几周内没有变化，表明这些测量值只有很小的学习效应。受试者内变异（表示为变异系数[ CV]的平均典型误差）表明，前舌强度（CV 10.8%）和后舌强度（CV 11.8%）和握力（CV 15.2%）的初始变异高于预期，但在第2-4周降低。组内相关系数（ICC）表明第1周后前（ICC 0.77-0.90）和后（ICC 0.79-0.86）舌强度和握力（ICC 0.69-0.91）的可靠性可接受和改善。对数据子集进行了额外的探索性分析，以确定5 kPa（舌）或15 kPa（手柄）内的两个值是否提供了优越的上级强度可靠性。无论是舌头还是手的耐力测量都不够可靠。这些研究结果表明，舌头和握力值表现出可接受的可靠性，特别是如果熟悉提供。需要进一步的研究来减少舌耐力测量的变异性来源。
The purpose of this study was to investigate the reliability of tongue and handgrip strength and endurance measurements in healthy adults using the Iowa Oral Performance Instrument. Fifty-one healthy participants (21 males, 30 females; age range = 19-57 years) were tested on four occasions 1 week apart to determine test-retest reliability. The primary outcome measures were isometric tongue and handgrip strength (best of three trials) and sustained isometric endurance. Small increases (changes in group mean) in both anterior (1.7 %) and posterior (2.5 %) tongue strength and handgrip strength (5 %) between weeks 1 and 2 were observed with no change in subsequent weeks, suggesting that there is only a small learning effect for these measurements. The within-subject variation (mean-typical error expressed as a coefficient of variation [ CV]) indicated higher than desirable initial variation for anterior (CV 10.8 %) and posterior (CV 11.8 %) tongue strength and handgrip strength (CV 15.2 %) but this was reduced in weeks 2-4. Intraclass correlation coefficients (ICC) indicated acceptable and improved reliability for both anterior (ICC 0.77-0.90) and posterior (ICC 0.79-0.86) tongue strength and handgrip strength (ICC 0.69-0.91) after week 1. Additional exploratory analyses were conducted with a subset of data to determine whether two values within 5 kPa (tongue) or 15 kPa (handgrip) provide superior strength reliability. Neither tongue nor hand endurance measurements were sufficiently reliable. These findings suggest that tongue and handgrip strength values demonstrate acceptable reliability, especially if familiarization is provided. Further investigation is needed to reduce sources of variability in tongue endurance measurements.
