ABSTRACT

Resumen Introducción: Las enfermedades reumáticas son patologías de alta prevalencia, impacto y repercusión, caracterizadas por dolor y limitación funcional. Para valorar la limitación, la historia clínica es el punto de partida, junto con las pruebas específicas necesarias, según el tipo de padecimiento. De forma complementaria, se recomienda el uso de herramientas clinimétricas. Objetivo: Comparar algunas herramientas o cuestionarios usados en las enfermedades reumáticas más prevalentes, revisando la bibliografía para destacar sus aportes y su utilidad en la labor del médico con finalidad clínica o pericial. Método: Se revisan las características básicas de los cuestionarios y herramientas más usadas en: osteoartritis, artritis reumatoide y artritis psoriásica, espondilitis anquilosante y lupus eritematoso sistémico. Se revisa en Medline la experiencia de los autores con algunos cuestionarios en función de la patología y de sus diversos usos. Resultados: Los cuestionarios se utilizan en su mayoría para la valoración de la calidad de vida, la discapacidad y la evolución clínico-terapéutica de los pacientes. No hay acuerdo entre los autores sobre si existe prioridad en el uso de algún cuestionario concreto por patología y se tiende a combinar varios. Los cuestionarios genéricos más utilizados son SF-36, NHP y EQ-5D. Por enfermedades: en artritis reumatoide, HAQy DAS28; en osteoartritis, WOMAC y Knoos; en Lupus, SLEDAI y BICLA, y en espondilitis, BASDAI y ASDAS. Conclusiones: En reumatología los cuestionarios son de uso habitual y resultan de utilidad de forma complementaria a la historia clínica y a las pruebas específicas. La elección por el profesional médico se basa en su experiencia y en la adecuación al objetivo buscado.


Abstract Introduction: Rheumatic diseases are high prevalence, high impact and repercussion pathologies characterised by pain and functional limitation. To assess the limitation, the starting point is the clinical history, together with the specific tests required according to the type of condition. The use of complimentary clinometric tools is recommended. Objective: To compare some tools or questionnaires used in the most prevalent rheumatic diseases, and a review of the literature to highlight their contributions and usefulness in medical practice by the clinician or expert. Method: A review is made of the basic characteristics of the questionnaires and the most used tools in osteoarthritis, rheumatoid arthritis and psoriatic arthritis, ankylosing spondylitis and systemic lupus erythematosus. The experience of the authors is reviewed in Medline, with some questionnaires depending on the pathology and its various uses. Results: The questionnaires are used mainly to assess the quality of life, disability, and clinical-therapeutic evolution of patients. There is no agreement among the authors on whether there is a priority in the use of a specific questionnaire by pathology, and there is a tendency to combine several. The most commonly used generic questionnaires are SF-36, NHP and EQ-5D. For diseases: in rheumatoid arthritis, the HAQ and DAS28; in osteoarthritis, WOMAC and Knoos; in lupus, SLEDAI and BICLA; and in spondylitis, BASDAI and ASDAS. Conclusions: In rheumatology, questionnaires are commonly used, and are useful as a complement to the clinical history and specific tests. The choice by the medical professional is based on their experience and on the adaptation to the objective sought.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate whether muscle fatigue indices obtained using surface electromyography and calculated in the time and frequency domains would be capable of objectively diagnosing pain and discriminating between subjects with and without pain in the upper trapezius muscle and the lower back muscles. METHODS: Forty-seven individuals underwent a muscle fatigue test for thirty-five seconds at 80% of the maximal voluntary contraction (MVC), while EMG and muscle force data were recorded. The RMS value and the median frequency (MF) were calculated within consecutive one-second windows. Linear regression analysis was used to obtain the slope coefficients and the respective y-axis intercept values, which were considered to be localized muscle fatigue indices. RESULTS: In the frequency domain, the slope coefficients were negative for both muscles, while in the time domain, the coefficient for the upper trapezius was positive and the coefficient for the lower back muscles was negative (p<0.01). Significant differences were also found in the frequency domain between subjects with and without pain in the upper trapezius (p<0.01). The subjects with pain had significantly lower force values than the subjects without pain (p<0.05), in both the upper trapezius and the lower back muscles. CONCLUSION: The force values associated with the fatigue indices (MF slope and y-axis intercept) were able to predict the presence of pain in the upper trapezius (p<0.05), but not in the lower back muscles.


OBJETIVO: A proposta do estudo foi investigar se índices de fadiga, obtidos a partir de eletromiografia de superfície, calculados no domínio do tempo e da frequência, são capazes de diagnosticar a dor objetivamente, discriminando entre sujeitos com e sem dor no trapézio superior e nos músculos lombares. MÉTODOS: Quarenta e sete indivíduos foram submetidos a um teste de fadiga muscular por 35s a 80% da contração voluntária máxima (CVM), enquanto EMG e força muscular foram registradas. O valor RMS e a mediana da frequência (MF) foram calculados em janelas consecutivas de 1s. Análise de regressão linear foi utilizada para obter os coeficientes de inclinação e seus respectivos valores de interseção no eixo y, os quais foram considerados índices de fadiga muscular localizada. RESULTADOS: Os coeficientes de inclinação analisados no domínio da frequência apresentaram comportamento similar, sendo negativos para ambos os músculos, enquanto que, no domínio tempo, o trapézio superior apresentou coeficientes positivos, e músculos lombares, coeficientes negativos (p<0,01). Diferenças significativas também foram identificadas no domínio da frequência entre os sujeitos com e sem dor no trapézio superior (p<0,01). Os indivíduos com dor apresentaram valores de força significativamente menores que os sujeitos sem dor (p<0,05), tanto nos músculos lombares quanto no trapézio superior. CONCLUSÃO: Os valores de força associados aos índices de fadiga (inclinação da MF e intersecção do eixo y) foram hábeis para predizer a presença de dor no trapézio superior (p<0,05), mas não nos músculos lombares.

ABSTRACT

OBJETIVO: O objetivo desse estudo foi verificar o potencial da eletromiografia (EMG) de superfície para a avaliação da eficiência neuromuscular e da fadiga muscular localizada dos extensores lombares em indivíduos com escoliose. MÉTODOS: Participaram deste estudo 20 indivíduos divididos igualmente em dois grupos, (1) Grupo com Escoliose e (2) Grupo Controle, que foram submetidos a um teste de indução dos músculos extensores lombares a fadiga, o qual constituiu da realização de uma contração voluntária máxima isométrica (CVM), e realização de um teste com esforço a 80 por cento da CVM. Foram coletados simultaneamente sinais de força e eletromiográficos (sinal EMG). O sinal EMG foi processado no domínio da freqüência, utilizando-se a transformada rápida de Fourier (FFT), por meio da mediana da freqüência (MF), e no domínio do tempo, pelo cálculo do valor root mean square (RMS). Os dados foram submetidos a uma análise de variância one-way para verificar as diferenças entre os dois grupos. Para verificar a simetria entre os lados direito e esquerdo, foi realizado o teste t pareado. O nível de significância adotado foi 0,05. RESULTADOS: os resultados demonstraram que indivíduos com escoliose apresentaram: (1) simetria de ativação neuromuscular entre os lados; (2) menor eficiência neuromuscular; (3) maior capacidade de resistir a fadiga; e (4) valores de força 42,6 por cento menores que os indivíduos do GC. CONCLUSÕES: Os resultados sugerem que a EMG de superfície corresponde a um efetivo instrumento de avaliação funcional da escoliose, embora o protocolo estabelecido tenha limitado a participação dos indivíduos com escoliose, do ponto de vista da eficiência neuromuscular.


OBJECTIVE: The aim of this study was to investigate the potential of surface electromyography (EMG) for assessing neuromuscular efficiency and localized muscle fatigue in the lumbar extensors, in individuals with scoliosis. METHODS: Twenty individuals participated in this study, divided equally into two groups: (1) Scoliosis Group and (2) Control Group. These subjects underwent a fatigue induction test on their lumbar extensor muscles, consisting of one maximum voluntary isometric contraction (MVIC) followed by a test at 80 percent of the MVIC effort. Force and EMG signals were collected simultaneously. The EMG signal was processed in the frequency domain by means of fast Fourier transforms using the median frequency; and in the time domain by calculating the root mean square value. The data were analyzed by means of one-way analysis of variance to investigate the differences between the two groups. Paired t test was used to investigate the symmetry between the right and left sides. The significance level adopted was 0.05. RESULTS: The results showed that the individuals with scoliosis presented: (1) symmetrical neuromuscular activation between the sides; (2) lower neuromuscular efficiency; (3) greater capacity to resist fatigue; and (4) force values 42.6 percent lower than those of the individuals in the Control Group. CONCLUSIONS: The results suggest that surface EMG is an effective tool for functional assessments of scoliosis, although the protocol established limited the participation of individuals with scoliosis, from the perspective of neuromuscular efficiency.
