Effects of high-intensity inspiratory muscle training associated with aerobic exercise in patients undergoing cabg: randomized clinical trial

Abstract Objective: Evaluate the interaction between high-intensity inspiratory muscle training (IMT) and aerobic exercise on physical capacity, respiratory muscle strength, peripheral muscle strength, and quality of life of patients who underwent coronary artery bypass grafting (CABG). Methods: Twenty-four patients underwent CABG were randomized into two groups. During 36 sessions, one group received IMT associated with aerobic exercise and the other group received only aerobic exercise. Primary outcome was the distance in the six-minute walk distance (6MWD) test. Secondary outcomes included respiratory muscle strength, peripheral muscle strength, and quality of life. Measures were taken at the baseline, at the 12th session, the 24th session, and 36th session. Results: Baseline characteristics were similar between the groups. There was no statistically significant difference between the two groups in any outcome [6MWD - P=0.935; peak oxygen consumption (PeakVO2) - P=0.853; maximal inspiratory pressure (MIP) - P=0.243; maximal expiratory pressure (MEP) - P=0.268; sitting-rising test (SRT) - P=0.212], but there was interaction in MIP (P=0.000) and all outcomes improved in the two groups (6MWD - P=0.000; PeakVO2 - P=0.000; MIP - P=0.000; MEP - P=0.000; SRT - P=0.000). Conclusion: There was an improvement of all outcomes in both groups, but IMT was not able to provide additional benefits. The use of this combination should be used with caution to not generate higher costs in the rehabilitation process of these patients.

Efeito da terapia por radiofrequência monopolar sobre a dor e capacidade funcional de mulheres com fibromialgia / Effect of monopolar radiofrequency on pain and functional capacity of women with fibromyalgia

Introdução: O tratamento através de eletroterapia é um recurso fisioterapêutico cada vez mais utilizado para a redução de quadros álgicos. No entanto, são escassos os estudos analisando os efeito da radiofrequência de modo contínuo não ablativo em pacientes com fibromialgia. Objetivo: Este estudo objetivou avaliar os efeitosda terapia por radiofrequência monopolar (RFM) na dor e no cotidiano de mulheres com fibromialgia. Método: Participaram deste estudo mulheres com diagnóstico clínico de fibromialgia, que foram submetidas a 8 sessões de RFM. Os atendimentos ocorreram 2 vezes por semana. Os resultados do tratamento foram avaliados pela Escala Visual Analógica (EVA) e pelo Fibromyalgia Impact Questionary (FIQ). Para comparar os resultados pré e pós tratamento utilizou-se o teste T Pareado do software Statistica 7.1. Resultados: Participaram deste estudo 9 mulheres com idade média de 53,25 (± 8,48) anos.Verificou-se alívio da dor imediatamente após as sessões de RFM (p <0,01). Houve repercussão positiva do tratamento no cotidiano dessas pacientes, visto que ocorreu significativa redução do escore do FIQ após as 8 sessões (p = 0,03). Conclusão: A partir dos resultados deste estudo, sugere-se que a terapia por RFM pode ser mais um aliado do fisioterapeuta para o tratamento de pacientes com fibromialgia. Contudo, os resultados desta pesquisa devem ser analisados com cautela, pois não houve um grupo controle para garantir que os resultados positivos deveram-se unicamente ao tratamento e não a outros fatores desconsiderados pelos pesquisadores.

Introduction: The treatment by electrotherapy is increasingly used as a therapeutic resource for reducing painful picture in Physical Therapy. However, there are few studies analyzing the effects of continuous and non-ablative radiofrequency in patients with fibromyalgia. Objective: This study evaluated the effects of monopolar radiofrequency on pain and daily life of women with fibromyalgia. Methods: The study included women diagnosed with fibromyalgia, who underwent eight sessions of RFM monopolar radiofrequency. The sessions occurred twice a week. The treatment results were evaluated by Visual Analogue Scale (VAS) and the Fibromyalgia Impact Questionnaire (FIQ). To compare the results before and after treatment, we used paired t-test from software Statistica 7.1. Results: The study included 9 women with mean age of 53.25 ± 8.48 years. Pain decreased immediately after the sessions of RFM (p < 0.01).There was positive impact in the daily treatment of these patients, with a significant reduction in the FIQ score after 8 sessions (p =0.03). Conclusion: The results suggest that RFM therapy can be an physiotherapist's help for the treatment of patients with fibromyalgia. However, this study should be analyzed with caution, because there was no control group to ensure that positive results were due solely to the treatment and not to other factors not considered by the researchers.
