Relação entre a tensão aplicada e a sensação de desconforto nos músculos isquiotibiais durante o alongamento

Abstract: Contextualização: O alongamento muscular é amplamente empregado no tratamento e na prevenção de doenças musculoesqueléticas. Estudos utilizam informações subjetivas do paciente como "desconforto" e "tensão sem dor" para limitar intensidade de alongamento, sem estabelecer uma tensão adequada de estiramento. Objetivo: Estudar a relação entre tensão aplicada e informações subjetivas, durante alongamento estático passivo para analise da reprodutibilidade e variações nas informações sensoriais. Métodos: Participara… Show more

“…Although this chapter has discussed the measurement of muscle strength by measuring EMG, it can be said that most applications of EMG are related to some aspect of muscle force generation, because the signal is generated when muscle contractile elements are activted. In this respect, it is pertinent to mention other methods, such as: i) the use of PCA (principal component analysis) to identify the pulse trains of action potentials on a surface electromyography signal collected with multiple electrodes (Nakamura et al, 2004); ii) application of multivariate statistical techniques and multidimensional visualization in 3D space -Viz3D (Artero, 2005), to identify differences between isometric activities carried out against a rigid obstacle and with a weight of equivalent inertial load (Mello, 2007); iii) applications in studies of muscle coordination, techniques that allow, through measures of EMG, set parameters for determining the action of various muscles; and iv) studies of the relationship between force sensation and muscle stretching (Branco et al, 2006). The magnitude of force or torque has also been compared with the spectral variables of the EMG signal (Bernardi et al, 1996, Bilodeau et al, 2003Gerdle et al, 1991;Hermans et al, 1999;Karlsson & Gerdle, 2001;Moritani & Muro, 1987;Onishi et al, 2000).…”

“…The subject was placed in a supine position on the abovementioned board, keeping the hip of the assessed limb fastened at a 90° flexed position, with the knee joint free to enable the assessment of its extension angle. A single researcher, who was blinded to group allocation, slowly performed continuous passive extensions of the knee to minimize possible reflexive interferences 19 , until the subject indicated a initial discomfort without pain 20 . The extensions were performed three times before and after the procedures 9,21 .…”

“…O alongamento, realizado na prática fisioterapêutica, tem o intuito de manter uma relação ótima de comprimento-tensão dos músculos, e desta forma, atuar no aumento das amplitudes de movimento (ADMs) perdidas, ou evitar a sua diminuição, que muitas vezes é conseqüência da imobilização (16)(17)(18) . Dessa forma o presente trabalho justifica-se na tentativa de esclarecer alguns fenômenos morfológicos que ocorrem durante o uso de técnicas de alongamentos, como método de remobilização em músculos previamente encurtados pela imobilização.…”
