“…Moreau et al () found a SM of 8.6 kPa (shear modulus) at level L2–L3 and 6.9 kPa at level L4–L5 in the multifidus at rest in prone position using SWE, and Chan et al () found a YM of 36 kPa, which corresponds to SM = 12 kPa, using strain elastography. By extension to other trunk muscles, mean stiffness using SWE ranged from 3.5 kPa for the internal oblique to 22 kPa for the external oblique (Hirayama et al, ; Tran et al, ). Such variability could result from significant interindividual and intermuscular stiffness differences.…”

Feasibility assessment of shear wave elastography to lumbar back muscles

Low back pain is often associated with tensional changes in the paraspinal muscles detected by palpatory procedures. Shear wave elastography (SWE), recently introduced, allows the stiffness of muscles to be assessed noninvasively. The aim of this work was to study the feasibility of using SWE on the three main lumbar back muscles (multifidus, longissimus, and iliocostalis) in vivo after analyzing their muscular architecture ex vivo. We determined the orientation of fibers in the multifidus, longissimus, and iliocotalis muscles in seven fresh cadavers using gross anatomy and B-Mode ultrasound imaging. We then quantified the stiffness of these three muscles at the L3 level ex vivo and in 16 healthy young adults. Little pennation was observed in the longissimus and iliocostalis, in which the direction of fibers was almost parallel to the line of spinous processes. The multifidus appeared as a multiceps and multipennate muscle. Given the random layering of millimetric fascicles, tendons, and fatty spaces, the multifidus had multiple fiber orientations. Muscular fascicles and fibers were oriented from 9° to 22° to the line of spinous processes. The shear moduli related to stiffness were 6.9 ± 2.7 kPa for the longissimus, 4.9 ± 1.4 kPa for the iliocostalis, and 5.4 ± 1.6 kPa for the multifidus. SWE is a feasible method for quantifying the stiffness of the lumbar back muscles. Clin. Anat. 30:774-780, 2017. © 2017Wiley Periodicals, Inc.

Posture‐related stiffness mapping of paraspinal muscles

et al. 2019

The paraspinal compartment acts as a bone–muscle composite beam of the spine. The elastic properties of the paraspinal muscles play a critical role in spine stabilization. These properties depend on the subjects’ posture, and they may be drastically altered by low back pain. Supersonic shear wave elastography can be used to provide quantitative stiffness maps (elastograms), which characterize the elastic properties of the probed tissue. The aim of this study was to challenge shear wave elastography sensitivity to postural stiffness changes in healthy paraspinal muscles. The stiffness of the main paraspinal muscles (longissimus, iliocostalis, multifidus) was measured by shear wave elastography at the lumbosacral level (L3 and S1) for six static postures performed by volunteers. Passive postures (rest, passive flexion, passive extension) were performed in a first shear wave elastography session, and active postures (upright, bending forward, bending backward) with rest posture for reference were performed in a second session. Measurements were repeated three times for each posture. Sixteen healthy young adults were enrolled in the study. Non‐parametric paired tests, multiple analyses of covariance, and intra‐class correlations were implemented for analysis. Shear wave elastography showed good to excellent reliability, except in the multifidus at S1, during bending forward, and in the multifidus at L3, during bending backward. Yet, during bending forward, only poor quality was recorded for nine volunteers in the longissimus. Significant intra‐ and inter‐muscular changes were observed with posture. Stiffness significantly increased for the upright position and bending forward with respect to the reference values recorded in passive postures. In conclusion, shear wave elastography allows reliable assessment of the stiffness of the paraspinal muscles except in the multifidus at S1 and longissimus, during bending forward, and in the multifidus at L3, during bending backward. It reveals a different biomechanical behaviour for the multifidus, the longissimus, and the iliocostalis.

“…However, Eby et al (2013) reported a strong linear relationship between muscle shear modulus and muscle Young's modulus. In several studies, SWE has been successfully used to quantify muscle Young's modulus (Bouillard et al 2011;Koo et al 2014;Ma€ ısetti et al 2012;Nordez and Hug 2010;Nordez et al 2008;Tran et al 2016). Some attempts have also been made to indirectly evaluate muscle forces based on muscle elasticity using SWE (Bouillard et al 2011;Kim et al 2018;Koo et al 2013).…”

The objective of this study was to investigate the feasibility of using shear wave elastography (SWE) to indirectly measure passive muscle force and to examine the effects of muscle mass and scan angle. We measured the Young's moduli of 24 specimens from six muscles of four swine at different passive muscle loads under different scan angles (0˚, 30˚, 60˚and 90˚) using SWE. Highly linear relationships between Young's modulus E and passive muscle force F were found for all 24 muscle specimens at 0 o scan angle with coefficients of determination R 2 ranging from 0.984 to 0.999. The results indicate that the muscle mass has no significant effect on the muscle EÀF relationship, whereas EÀF linearity decreases disproportionately with increased scan angle. These findings suggest that SWE, when carefully applied, can provide a highly reliable tool to measure muscle Young's modulus, and could be used to assess the muscle force quantitatively.
