Surface Electromyographic Studies of Swallowing in Normal Subjects: A Review of 440 Adults. Report 3. Qualitative Data

Abstract

The normal muscle activity during swallows and drinking has several graphic patterns which can be identified and described similar to EKG records when surface EMG is rectified and filtered. The method of EMG recording is quick and simple, and can be used for screening and evaluation purposes in outpatient and inpatient ENT departments. These parameters represent activities required for normal deglutition, and can be used to identify abnormalities in ENT patients, and provide a basis for comparison of swallowing performance both within and between patients. These normal data form a valuable basis for future comparison with patients in pre- and postoperative stages and in EMG monitoring during ENT treatment.

Age and gender effects on submental motor-evoked potentials

“…Kleim and Jones (2008) found no age effects in submental muscle activity during various swallowing tasks consisting on different textures and tastes of liquids and solids. However, Vaiman et al (2004) found a non-significant trend toward a decrease in submental activity during swallowing with age, which supports the current results. Age-related changes in muscle properties, known as sarcopenia (Evans 1995), can affect MEP and sEMG magnitude, since they are recorded from peripheral muscles.…”

“…Another study measured MEPs from the upper limb and found no gender effects on MEP magnitude and latency in younger subjects, after correcting the latencies for the subject's arm length (Livingston et al 2010). Previous research also found no gender effects on non-stimulated submental sEMG amplitude during swallowing (Vaiman et al 2004).…”

“…Age-and gender-related differences in MEPs from the submental muscle group during swallowing have not been investigated, while age effects have been indicated in submental muscle activity during swallowing (Vaiman et al 2004). The question of age and gender effects on MEPs was explored as a by-product of analyzing data for another research hypothesis.…”

Surface electromyography: diagnostic input for atypical swallowing as an aid for choosing therapy

“…It highlights the repetition of a movement or a function of a muscle or muscle group 4,10,11,13,18,20,26,29,[40][41][42][43][44][45][46][47] .…”

Funções orofaciais em portadores de síndrome de Sjögren

“…Vaiman et al, (2004a, b) analisaram a deglutição de volume livre de água, volume excessivo de água e de 100mL de agua. Foram consideradas as seguintes variáveis: duração da deglutição de saliva e 100mL, número e mL por deglutição em 100mL (Vaiman et al, 2004a), pico de atividade de masseter e temporal na deglutição de saliva (Vaiman et al, 2004b). Nesta amostra, foi verificado que a duração média da deglutição de saliva para indivíduos com menos de 70 anos foi de 3,22 segundos, considerando as fases oral e faríngea, e a deglutição de 100mL para a mesma faixa etária durou de 10,9±2,3 a 13,4±4,0.…”
