“…Seria uma forma de minimizar a dificuldade na análise da excursão diafragmática. Porém é importante ressaltar a dificuldade na fixação dos eletrodos, pois tal técnica é dolorosa, desconfortável e por ser invasiva acarreta em riscos para o paciente [36].…”

Resumo: Nos últimos anos, o interesse na análise de sinais de eletromiografia dos músculos respiratórios tem aumentado devido ao número de doenças neuromusculares e respiratórias que impactam na força diafragmática e sobrecarregam os músculos acessórios. Porém o registro adequado da excursão diafragmática é um grande desafio. O presente artigo busca e apresentar os desafios a respeito da viabilidade do uso da eletromiografia (EMG) de superfície para análise da atividade elétrica muscular do diafragma. Com esse propósito foram procurados na literatura artigos com possíveis padronizações de posicionamento de eletrodos, e realizado as mensurações de cinco pacientes sendo três idosos portadores da doença de Parkinson e dois jovens saudáveis. O aparelho utilizado foi o Miotool (Empresa Miotec®, eletrodos em formato Jacaré). Observou-se que a falta de um consenso a cerca do opcionalmente dos eletrodos de superfície dificulta uma metodologia eficaz para que se obtenha a captação do sinal eletromiográfico do músculo diafragma. Sendo assim, sugere-se a criação de um protocolo para posicionamento da musculatura diafragmática para melhor captação e análise dos sinais. Palavras

“…Surface EMG is the method used to non-invasively measure potential differences of muscles in the body compared to a ground electrode [84]. The ground is placed at an inert location, not contributing to the measured muscle contraction being investigated, in case of respiratory measurements the sternum is chosen [25][26][27]85].…”

D30. Asthma: What’s New in Assessment and Treatment?

Rationale Asthma is one of the most common chronic diseases in childhood, occurring in up to 10% of all children. Exercise induced bronchoconstriction (EIB) is indicative of uncontrolled asthma and can be assessed by means of an exercise challenge test (ECT). These tests however draw heavily on healthcare resources and require demanding repetitive forced breathing manoeuvres of children. In this study the electric activity of the respiratory muscles was measured as a tool to assess EIB. Methods Children suspected of exercise induced respiratory symptoms performed an ECT wearing a portable EMG amplifier (Dipha-16, Demcon Macawi respiratory systems, Enschede, the Netherlands). EIB was defined as a fall in FEV1 of greater than 13%. Electrodes were placed bilaterally at the diaphragm and accessory breathing (intercostal-, sternocleidomastoid-and trapezoid) muscles. A single reference electrode was placed at the sternum. Children were asked to sit still for 30 seconds after each spirometry measurement to obtain EMG measurements. Data was pre-processed and analyzed in Matlab.

“…This device is useful in evaluating the neurophysiological condition of the motoric nerves, peripheral nerves, and the muscle function [1]. It has been shown that ENMG plays role in detecting the muscle activity in the patients with chronic respiratory disease [2], evaluating the respiration pattern of newborn baby, predicting the lung function of the children with asthma [3], detecting speaking ability in deaf people [4], and fatigue analysis [5]. The ENMG is not only a powerful tool for study the muscle function in human, but also in animals [6].…”

“…Although ENMG has a wide application, the use of ENMG is still limited due to the limited access [3], especially in the developing countries such as in Indonesia. The availability of ENMG is limited in the big hospitals in urban area, causing an expensive cost to perform the test.…”

Muscle is one of body tissues which is excitable. It poses an electrical activity during contraction and relaxation which could be measured using an electrical device called as electroneuromyograph (ENMG). This device has a wide application in neurophysiology, biomechanics, fatigue analysis, and ergonomic, as well as sports. However, there is a limited access to this device for research due to its scarce availability which is mainly found in certain hospitals in urban area causing an expensive cost to perform the test. This paper presents a work in measuring biopotential produced from activity of lower arm muscles using a simple ENMG module. An instrumentation amplifier was used to amplify signals from the muscle which are detected using three surface electrodes connected to the amplifier using an EMG cable. The output signal was displayed using an oscilloscope. The results show that the average value of the peak-to-peak voltage during contraction and relaxation were 460 mV and 32.6 mV, respectively. This indicates that a simple ENMG module can be used for measurement the electrical activity of the muscle tissues. The measured signal fluctuated during the measurement, which is possibly caused by the arm position during measurement, the attachment of the surface electrode on the skin surface and the body movement during measurement.
