This study collected 11 parameters regarding the labial and lingual strength for maximum isometric and swallowing tasks among 150 healthy Chinese adults in Taiwan. Measurements were performed using the Iowa Oral Performance Instrument (IOPI). All of the labial and lingual strength parameters were measured three times. The maximal value of three trials represents the pressure of every parameter. The overall mean (±standard deviation) and maximum isometric pressures of the lips, anterior tongue, and posterior tongue were 24.81 ± 5.64, 55.95 ± 14.13, and 53.23 ± 12.24 kPa, respectively. The mean value of posterior tongue strength was less than that of the anterior tongue by approximately 5%. The percentages of maximum isometric tongue pressure during the swallowing of saliva and water were 85% and 80% for the anterior tongue and 90% and 81% for the posterior tongue, respectively. The average endurances for the anterior tongue and posterior tongue were 13.86 ± 7.08 and 10.06 ± 5.40 s, respectively. The maximum isometric pressures were greater than both the saliva and water swallowing pressures, and the saliva swallowing pressures were greater than the water swallowing pressures. A value of 33 kPa in maximum isometric pressure could serve as a demarcation of weak tongue strength for healthy Chinese adults. As for the repeated trials of labial and lingual strength, there were no statistically significant differences for any of the pressures obtained from the 11 labial and lingual strength parameters. The normative data can be used for the objective assessment of labial and lingual strength in healthy Chinese adults.
本研究共纳入 150 名台湾地区健康成年人，采用爱荷华口腔功能测试（IOPI），收集唇、舌最大等长收缩和吞咽运动的 11 项参数。所有唇、舌力参数均测量 3 次，取 3 次试验的最大值代表每个参数的压力。唇、前舌、后舌的最大等长压力的平均值（±标准差）和最大值分别为 24.81 ± 5.64kPa、55.95 ± 14.13kPa 和 53.23 ± 12.24kPa。后舌力的平均值比前舌力小约 5%。前舌在吞咽唾液和水时的最大等长压力百分比分别为 85%和 80%，后舌分别为 90%和 81%。前舌和后舌的平均耐力分别为 13.86 ± 7.08s 和 10.06 ± 5.40s。最大等长压力大于唾液和水吞咽压力，而唾液吞咽压力大于水吞咽压力。最大等长压力 33kPa 可作为健康中国成年人弱舌力的划分值。对于唇、舌力的重复试验，11 项唇、舌力参数的任何压力均无统计学差异。本研究提供的正常值可用于健康中国成年人唇、舌力的客观评估。
