“…The increase in fatigue may be expected, given the demands of the vocal loading task. The increase in muscular soreness is associated with a novel form of exercise [27] and has been previously reported in studies involving simulated vocal loading using neuromuscular electrical stimulation [28][29][30] of interest are the comments provided by the participants upon completion of the study. Five of the seven participants reported having one or more of the following symptoms: dry throat, sore throat, headache, increased difficulty when swallowing, slow/sluggish voice, scratchy voice, raspy voice, painful talking, dry lips, and reduced talking.…”

Objective: To determine the effect of a vocal loading task on vocal function before and after 24 hours of thickened liquid use.Methods: Seven healthy adults, ages 19 to 52 years of age, were recruited as participants. Baseline data regarding daily food/liquid intake and urine specific gravity levels (USG) as a marker of hydration were obtained. Participants then completed a vocal loading task, which consisted of 3 × 10 repetitions of a sustained vowel task at 65 dB to 75 dB SPL. Voice recordings and subjective ratings of vocal fatigue and muscle soreness were obtained prior to and following the vocal loading task for both the pre-thickened liquid and post-thickened liquid experimental session. The voice samples were analyzed for changes in fundamental frequency, loudness, and perturbation measures.Results: There was a significant main effect of vocal loading on vocal loudness as well as subjective ratings of vocal fatigue and muscle soreness; all parameters were higher post-vocal loading. There was also a significant main effect of thickened liquid use on jitter, as jitter levels were substantially lower post-thickened liquids. Conclusion:The objective and subjective changes reported by the participants' post-vocal loading are consistent with prior reports concerning normal adaptive responses to greater vocal demands and increased muscular effort. A brief period of thickened liquids does not appear to affect vocal function.

“…Não há evidência em relação ao melhor tempo de eletroestimulação. Dois estudos com o aparelho VitalStim®, utilizaram respectivamente 60 minutos e 30 minutos de eletroestimulação e em ambos os tempos foram considerados excessivos, pois os participantes apresentaram indícios de fadiga (Fowler et al, 2011;Fowler et al, 2011). Fowler et al (2011) As musculaturas da laringe têm como maior prevalência fibras do tipo IIA, que são fibras musculares de contração rápida e resistentes à fadiga (Behlau, 2001).…”

“…O laringoespasmo é um reflexo de fechamento glótico intenso e prolongado, potencialmente fatal se não diagnosticado ou tratado a tempo (Kobaika & Lorentz, 2009). Dos estudos pesquisados que realizaram estimulação elétrica por corrente excitomotora com eletrodos em região de laringe não há referência à presença de espasmos glóticos independentemente do tipo de corrente e intensidade aplicada (Ptock & Strack, 2008;Guzman et al, 2014;Lagorio et al, 2010;Fowler et al, 2011;Garcia-Perez -Perez et al, 2014;Gorham-Rowan et al, 2016;Ko et al, 2016;Santos et al, 2016;Seifpanahi et al, 2017;Law et al, 2017). Para isso será necessário realizar a gravação da voz.…”

“…Apesar dos estudos voltados para esta técnica na fonoaudiologia terem apresentado um aumento significativo de publicações nos últimos anos, a utilização da estimulação elétrica por corrente excitomotora ainda é restrita, sem consenso em relação ao tempo e intensidade do estímulo elétrico que não produza sobrecarga ou fadiga ao paciente (Lagorio et al, 2010;Fowler et al, 2011;Fowler et al, 2011;Guzman et al, 2014;Garcia-Perez et al, 2014;Gorham-Rowan et al, 2016;Ko et al, 2016;Seifpanahi et al, 2017;Law et al, 2017 (Pellicani et al, 2017).…”

According to most previous studies, inducing movements in internal laryngeal muscles by transcutaneous electrical stimulation (TES) was impossible. However, the movements have been reported after using needle electrodes inserted into the internal superior laryngeal nerve (ISLN). Herein, we aimed to apply an innovative TES protocol to cause movements in vocal folds. A short duration and high frequency electrical current was applied by two surface electrodes just above the entrance of ISLN to larynx. The subjects were 32 normal participants (mean age = 23.87; SD = 3.43). During TES application, the vocal folds' movements were examined by flexible videonasolaryngoscopy. Statistical paired t test was used to analyze the differences of vocal folds opening angle, in degrees, during rest and TES periods. Furthermore, the movements were judged by seven experienced speech pathologists via a 9-point rate scale from -1 (any abduction) to 8 (complete adduction). The mean vocal folds adduction increased by 35.68° (t = 9.35, p > 0.001) due to TES application. The mean qualitative scores assigned by raters to each subject were between 6 and 7 points, which indicate an acceptable adduction in vocal folds through TES. Unlike previous studies, the applied TES protocol in this research induced significant vocal fold movements. This might be attributed to our different stimulation parameters, which were designed to penetrate deeply and stimulate ISLN specifically. It is worth noting that we introduced a novel TES protocol, which should be confirmed and then examined as a complementary therapy for neurologic voice disorders in future studies.
