Soft tissue texture analysis by B-mode-ultrasound in the evaluation of impairment in chronic low back pain

The significance of muscle echo intensity on ultrasound for focal neuropathy: The median- to ulnar-innervated muscle echo intensity ratio in carpal tunnel syndrome

“…Muscle atrophy and replacement of muscle tissue with fat and collagen make muscle tissue heterogeneous in imaging studies (Maurits et al, 2003). Few US-based studies of muscle inhomogeneity have been conducted (Cady et al, 1983;Dock et al, 1990;Eisele et al, 1998;Maurits et al, 2003). These previous studies adopted complex calculations for markers of inhomogeneity, unlike the simple method used in this study: the standard deviation of pixel brightness values in the ROI.…”

Quantitative ultrasound tissue characterization in shoulder and thigh muscles – a new approach

“…Ultrasonographic evaluation of the human muscles has been performed in studies on the quadriceps muscle, the arm, low-back, and masticatory muscles [ 6 , 11 , 12 ]. Most studies used a subjective evaluation in terms of a visual inspection of the images or measurements of the muscle thickness, and only a few studies have used quantitative ultrasound to characterize the various components of the muscle tissue [ 4 , 11 , 13 - 15 ]. The quantitative evaluation included the distribution of the grey-scale levels of the pixels in the images to describe tissue characteristics.…”

Application of rehabilitative ultrasound in the assessment of low back pain: A literature review

“…Fourteen studies of the 36 studies selected Kennelly and Stokes, 1993;Hides et al, 1994;Eisele et al, 1998;Coldron et al, 2003;Watanabe et al, 2004;Ainscough-Potts et al, 2006;Lee et al, 2006;Rankin et al, 2006;Springer et al, 2006;Hides et al, 2007b;Hides et al, 2008a;Wallwork et al, 2009), investigated muscle dimensions in different positions in healthy subjects or correctly identified patients with LBP from normal subjects based on US imaging findings. Only one study tried to identify the relationship between pain intensity and US imaging findings and in which no relationship was found between these two variables.…”

“…A significant difference was found in CSA of lumbar MF between the two sides of curve Hides et al (1994) ALBP (26), NLBP (51) CSA (MF) The effect of LBP on muscle size Positive. A significant difference was found in CSA of MF between-side and between the two groups at one level Eisele et al (1998) A Z NLBP (30) Positive. The pattern of relative muscle thickness was RA > IO > EO > TrA, but no significant difference was found in muscles between the left and right sides Springer et al (2006) NLBP ( (13) Thickness (TrA) Positive.…”
