Análise da pressão da língua em indivíduos adultos jovens brasileiros

Abstract

Purpose: To present the measures for tongue pressure in Brazilian young adults, considering specific tasks, and to verify the differences regarding gender and according to the tasks. Methods: Fifty-one volunteers aged 18 to 28 years, of both genders with normal occlusion and without speech disorders were evaluated. We used the Iowa Oral Performance Instrument in the evaluation of tongue pressure (kilopascal) during specific tests of elevation, protrusion, swallowing, and lateralization, in addition to the endurance test (seconds). The analysis was conducted using analysis of variance, followed by the Tukey's multiple comparison test, adopting a 5% men compared with women for the protrusion and lateralization tasks. The measures of the protrusion and elevation tasks did not differ for men but were higher in both genders than those of the lateralization and the swallowing tests. There was no difference in lateralization according to side in both the genders. Conclusion:The measures for the tongue pressure in Brazilian young adults were determined by specific tasks. Gender influenced the pressure of the tongue values for the protrusion and lateralization tasks. Elevation and protrusion tasks measures were higher than those of the lateralization and swallowing tasks. RESUMOObjetivo: Apresentar valores para a pressão da língua em adultos jovens brasileiros, considerando provas específicas e possíveis diferenças quanto ao gênero e tipo de prova. Método: Foram avaliados 51 voluntários de 18 a 28 anos, ambos os gêneros, com boa relação dento-oclusal e sem alterações de fala. Utilizou-se o Iowa Oral Performance Instrument na avaliação da pressão da língua (Kilopascal) durante as provas de elevação, protrusão, deglutição e lateralização, além do teste de resistência (segundos). Na análise dos resultados foi utilizado o ANOVA, seguido do teste de comparações múltiplas Tukey, adotando o nível de significância de 5%. Resultados:Os valores obtidos, respectivamente para homens e mulheres, na prova de elevação foram 63,94±12,92 e 50,27±15,29, na protrusão 60,22±13,62 e 44,30±12,95, na deglutição 33,94±12,06 e 34,27±13,25, na lateralização à direita 44,15±10,47 e 31,85±8,46, na lateralização à esquerda 43,15±10,22 e 29,55±8,91, e no teste de resistência 24,85±10,95 e 17,35±6,71. Os homens apresentaram valor maior nas provas de protrusão e de lateralização; os valores das provas de protrusão e elevação não diferiram entre si para o gênero masculino, mas foram maiores que a lateralização e a deglutição em ambos os gêneros; não houve diferença na prova de lateralização em relação ao lado em ambos os gêneros. Conclusão: Valores de pressão da língua em adultos jovens brasileiros foram determinados para provas específicas; o gênero influenciou nos valores das provas de protrusão e lateralização; os valores obtidos nas provas de elevação e protrusão foram maiores que na lateralização e deglutição.

Age and Sex-Related Differences in the Tongue Pressure Generated during Maximum Isometric and Swallowing Tasks by Healthy Chinese Adults

“…The effect of age on tongue SP was nonsignificant. SP remains stable throughout the majority of life, supporting previous findings [4,25,26]. However, in contrast, one Korean study demonstrated that the tongue pressure used during swallowing was statistically significantly higher for older adults than for younger adults [27].…”

“…Prandini et al [26] recruited 51 Brazilian volunteers aged 18-28 years to measure tongue pressure during specific tasks, e.g., tongue elevation, endurance, and swallowing. The results showed that sex had no influence on these tasks.…”

Analysis of Labial and Lingual Strength among Healthy Chinese Adults in Taiwan

“…The literature suggests that healthy adults should have maximum isometric tongue pressures ≥ 40 kPa, and SSPs between 20 and 30 kPa [13]. The percentages of maximum isometric tongue pressure generated during saliva swallowing and water swallowing were 40-60% [9,33]. However, Peladeau-Pigeon et al analyzed the swallowing tasks of 84 healthy participants and found that the peak amplitudes of saliva swallowing, on average, ranged from 70% to 81% of the values obtained for the MIP ant [34].…”

Maximum isometric tongue strength and tongue endurance in healthy adults

“…25 Recent studies attempted to establish norms for populations from different regions and countries with the effort to provide accurate normative control data for assessments. 2,4,21,30,31 Results of these studies found that both tongue strength and endurance measurements failed to demonstrate consistency among the population studied from different countries, 32 which emphasized the importance of avoiding directly referencing normative data from other populations during the assessment without careful consideration.…”
