Feasibility of Using Magnetic Resonance Elastography to Study the Effect of Aging on Shear Modulus of Skeletal Muscle

Abstract: A common complication associated with aging is the stiffening of skeletal muscles. The purpose of this study was to determine the ability of magnetic resonance elastography (MRE) to study this phenomenon in vivo. Twenty female subjects were included in the study with an age range of 50 to 70 years. Shear modulus was calculated for the tibialis anterior of each subject. There was not a significant relationship between age and shear modulus. However, three subjects had abnormally high values and were among the o… Show more

“…Additional architectural characteristics of muscle were obtained with magnetic resonance elastography (MRE) technique. Indeed, this method generates shear waves inside the muscle tissue in order to measure the mechanical properties (Dresner et al, 2001;Basford et al, 2002;Bensamoun et al, 2006Bensamoun et al, , 2007Brauck et al, 2007;Chen et al, 2007Chen et al, , 2008Domire et al, 2009) and several studies have observed the propagation of the shear waves along the muscle fiber (Bensamoun et al, 2006;Sack et al, 2002). Thus, V-waves, oblique waves and longitudinal waves were observed inside the biceps brachii, the vastus medialis and the sartorius muscles, respectively, reflecting their own muscles architecture.…”

“…Tissue properties are extracted by post-processing. MRE has been used to assess tissue properties in several areas of the body such as the breast (Lorenzen et al, 2003), brain (Green et al, 2008), liver (Huwart et al, 2006), heart (Sack et al, 2009), lung and skeletal muscle (Domire et al, 2009;Uffmann et al, 2004;Basford et al, 2002). The purpose of this work was to measure the viscoelastic properties of the human tongue in-vivo using MRE.…”

“…Previous studies on the age differences of muscle shear modulus were rare. Domire et al [8] measured the stiffness of lower leg muscle using MRE in a relaxed state on 20 female subjects with an age range of 50 to 70 years. They found that there was no significant effect of age on the muscle stiffness.…”

“…from 0% to 100% maximum voluntary contraction (MVC). In addition, although some studies have been performed on muscle stiffness of the subjects with different age ranges [8] and different gender [9], the effects of age and gender on the relationship between muscle stiffness and isometric contraction level have not been systematically studied.…”
