“…goal that remains somewhat constant and is based not on an absolute value but rather one that is proportional to an individual's physiologic range. Speech is a low-force task, and work by Solomon and Robin (2005) has indicated that the perception of effort during tongue movements (nonspeech in this case) relative to pressure generation was more sensitive at the extremes of the effort range. That is, the tongue may be more sensitive to effort differences at the low (and high) end of the tongue pressure physiologic range, allowing for a %Max target to be reliably attained.…”

Purpose: This preliminary study on lingual-alveolar contact pressures (LACP) in people with amyotrophic lateral sclerosis (ALS) had several aims: (a) to evaluate whether the protocol induced fatigue, (b) to compare LACP during speech (LACP-Sp) and during maximum isometric pressing (LACP-Max) in people with ALS (PALS) versus healthy controls, (c) to compare the percentage of LACP-Max utilized during speech (%Max) for PALS versus controls, and (d) to evaluate relationships between LACP-Sp and LACP-Max with word intelligibility. Method: Thirteen PALS and 12 healthy volunteers produced /t, d, s, z, l, n/ sounds while LACP-Sp was recorded. LACP-Max was obtained before and after the speech protocol. Word intelligibility was obtained from auditory-perceptual judgments.Results: LACP-Max values measured before and after completion of the speech protocol did not differ. LACP-Sp and LACP-Max were statistically lower in the ALS bulbar group compared with controls and PALS with only spinal symptoms. There was no statistical difference between groups for %Max. LACP-Sp and LACP-Max were correlated with word intelligibility. Conclusions: It was feasible to obtain LACP-Sp measures without inducing fatigue. Reductions in LACP-Sp and LACP-Max for bulbar speakers might reflect tongue weakness. Although confirmation of results is needed, the data indicate that individuals with high word intelligibility maintained LACP-Sp at or above 2 kPa and LACP-Max at or above 50 kPa.

“…Fatigue is a common complaint in disease states such as Parkinson's disease (PD), various cancers, autoimmune disorders, and viral infections (7,18,20,32) and may be associated with increased levels of IL-1␤. This cytokine has been shown to be elevated in the brains of subjects with PD (22), and IL-1␤ appears to be involved with cachexia associated with various cancers (13).…”

Brain cytokines, induced by various inflammatory challenges, have been linked to sickness behaviors, including fatigue. However, the relationship between brain cytokines and fatigue after exercise is not well understood. Delayed recovery of running performance after muscle-damaging downhill running is associated with increased brain IL-1beta concentration compared with uphill running. However, there has been no systematic evaluation of the direct effect of brain IL-1beta on running performance after exercise-induced muscle damage. This study examined the specific role of brain IL-1beta on running performance (either treadmill or wheel running) after uphill and downhill running by manipulating brain IL-1beta activity via intracerebroventricular injection of either IL-1 receptor antagonist (ra; downhill runners) or IL-1beta (uphill runners). Male C57BL/6 mice were assigned to the following groups: uphill-saline, uphill-IL-1beta, downhill-saline, or downhill-IL-1ra. Mice initially ran on a motor-driven treadmill at 22 m/min and -14% or +14% grade for 150 min. After the run, at 8 h (wheel cage) or 22 h (treadmill), uphill mice received intracerebroventricular injections of IL-1beta (900 pg in 2 microl saline) or saline (2 microl), whereas downhill runners received IL-1ra (1.8 microg in 2 microl saline) or saline (2 microl). Later (2 h), running performance was measured (wheel running activity and treadmill run to fatigue). Injection of IL-1beta significantly decreased wheel running activity in uphill runners (P<0.01), whereas IL-1ra improved wheel running in downhill runners (P<0.05). Similarly, IL-1beta decreased and Il-1ra increased run time to fatigue in the uphill and downhill runners, respectively (P<0.01). These results support the hypothesis that increased brain IL-1beta plays an important role in fatigue after muscle-damaging exercise.

“…It is portable and easy to use, is noninvasive, and presents fast, accurate, and reliable measurements (4)(5)(6) . After that, many studies proposed to measure the pressure made by the tongue on the oral cavity (7) during functions such as speech (8) , swallowing, (5) and chewing (9) ; at rest (10) ; and during the maximum isometric contraction for comparing with different portions of the tongue (anterior and dorsum) among young adults (11) . The pressure of the tongue has also been studied in relation to gender (11)(12)(13)(14) and age (5,(13)(14)(15) in individuals diagnosed with obstructive sleep apnea (16) , neurological conditions (17) , and disorders in the head and neck area (18) .…”

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.
