“…The tongue EIM ICCs are at least on par with the ICCs for test–retest reliability obtained using the Iowa Oral Performance Instrument, a standard measure of anterior tongue strength (Adams et al, 2014, 2015). Perhaps surprisingly, the tongue EIM repeatability data attained with the small array are also comparable to those previously reported for the larger tongue depressor EIM array (Shellikeri et al, 2015).…”

Objectives Electrical impedance myography (EIM) measurements of the tongue could provide valuable information about bulbar dysfunction in amyotrophic lateral sclerosis (ALS). A prototype tongue depressor EIM array produced gag reflexes. The objectives of this study were to determine the reliability, mean phase values, and tolerability of tongue EIM measurements using a smaller electrode array. Methods Tongue EIM measurements were performed in a total of 31 healthy individuals and four neuromuscular patients with lingual abnormalities. Reliability was assessed by calculating the intraclass correlation coefficient (ICC) and percent difference in addition to performing Bland–Altman analyses. Standard descriptive statistics, including results of a Mann–Whitney test, were also determined. Results At the 50 kHz frequency, the ICCs for intra- and inter-rater reliability were 0.76 with 5.17% difference and 0.78 with 5.34% difference respectively. The mean EIM phase values of healthy participants (11.61° ± 1.00°) and patients (9.87° ± 1.28°) were significantly different (p = 0.0051). None of the participants experienced gag reflexes or discomfort. Conclusions The small tongue array provided good inter- and intra-rater reliability, could preliminarily distinguish between healthy and diseased muscle, and was well-tolerated. Significance Biomarker information about tongue health could be more comfortably obtained with a smaller EIM array.

“…Accordingly, previous studies compared tongue and hand muscle function in regard to strength (Buehring et al 2013), fatigue (Solomon et al 2002; Adams et al 2014a; Adams et al 2014b) movement precision (Sutton et al 1977) and force regulation (Adams et al 2014b). The results of this work indicate that the control is comparable in each structure although pinpoint accuracy of the hand appears somewhat greater – at least within the context of displacement (Sussman, 1971).…”

Phonation-related rate coding and recruitment in the genioglossus muscle

2015

Motor unit (MU) recruitment was assessed in two muscles with similar muscle fiber type compositions and that participate in skilled movements: the tongue muscle, genioglossus (GG) and the hand muscle, first dorsal interosseous (FDI). Our primary objectives were to determine in the framework of a voluntary movement whether muscle force is regulated in tongue as it is in limb i.e., via processes of rate coding and recruitment. Recruitment in the two muscles was assessed within each subject in the context of ramp force (FDI) and in the tongue (GG) during vowel production and specifically, in the context of ramp increases in loudness, and subsequently expressed relative to the maximal. The principle findings of the study are that the general rules of recruitment and rate coding hold true for both GG and FDI and second, that average firing rates, firing rates at recruitment and peak firing rates in GG are significantly higher than for FDI (P <0.001) despite tasks performed across comparable force ranges (∼2-40% of max). The higher firing rates observed in the tongue within the context of phonation may be a function of that muscle's dual role as (prime) mover and hydrostatic support element.

“…And the exercise of pressing the IOPI bulb against the palate proved to be efficient in improving the swallowing of individuals who suffered cerebrovascular accident 19 . Moreover, researches carried out with adults 7 and elderly 20 showed that the IOPI tongue pressure values presented acceptable reliability.…”

Correlation between tongue pressure and electrical activity of the suprahyoid muscles

Objective: to investigate the correlation between the tongue pressure and the electrical activity of the suprahyoid muscles. Methods: a across-sectional, observational and analytical study conducted with 15 men and 22 women. Each participant underwent simultaneous assessment of maximal tongue pressure through the Iowa Oral Performance Instrument (IOPI) and the surface electromyography of the suprahyoid muscles. They were asked to press the tongue against the hard palate in the anterior and posterior region, with and without IOPI. The adopted significance level of the performed analyses was 5%.Results: there was a moderate and significant correlation only between suprahyoid electrical activity and tongue pressure in the posterior region. It was verified that the measured electrical potentials, when using the IOPI, were greater in the tasks of anterior pressure than in the tasks of the posterior one, bilaterally. Without using the IOPI, the electrical potentials were greater in the posterior pressure than in the anterior one, bilaterally. Finally, the values of lingual pressure were compared with the bulb positioned in the anterior and posterior parts, and the anterior tongue pressure was higher. Conclusion: there was a moderate correlation between tongue pressure and electrical potential of the suprahyoid muscles, researched by the surface electromyography, only when performing activities with the posterior portion of the tongue.

Reliability of measurements of tongue and hand strength and endurance using the Iowa Oral Performance Instrument with elderly adults

Abstract: These findings indicate that overall tongue and hand strength values demonstrate acceptable reliability in the elderly, especially where familiarisation with the IOPI is provided. Further investigation to reduce sources of variability in tongue endurance measurements is warranted.
