“…Given the current evidence of morphological changes and abdominal muscle functional deficits present during pregnancy [8], a group of nulliparous healthy women was enrolled as controls in this study. Generally, the range of SWS values acquired in the four abdominal wall muscles (0.85-2.08 m/s) was similar to the values reported by others [15,[25][26][27][28]. From a biomechanical viewpoint, the abdominopelvic cavity is a cylinder enveloped by muscles, tendons, and bony structures.…”

“…Shear wave speeds would probably decrease with increasing scanning depth [24]. Comparatively, more recent studies demonstrated that, in terms of inter-or intra-operator variability, shear wave elastography is a more reliable and widely used tool for quantitatively assessing muscle stiffness [25][26][27][28][29].…”

“…However, subgroup analysis in 36 DRA patients showed a positive correlation between IRD and SWS. This can be explained by the biomechanical and pathological changes in muscle fibers as the inter-rectus separation increases [25][26][27]. The composition of the RA, including muscle fibers, connective tissue, and adipose tissue infiltration, might vary at different stages of DRA progression, resulting in changes in shear wave speed at the later stage.…”

Objective To determine the value of shear wave elastography (SWE) in assessing abdominal wall muscles, including rectus abdominis (RA), external oblique muscle (EO), internal oblique muscle, and transversus abdominis (TrA) in patients with diastasis recti abdominis (DRA) and healthy controls. Methods From October 2018 to December 2019, 36 postpartum DRA patients and 24 nulliparous healthy women were identified. Inter-rectus distance (IRD) measurements were taken by B-mode ultrasound. Shear wave speed (SWS) values were acquired by one operator at ten specific locations. Clinical and ultrasound variables, including demographics, IRD, muscle thickness, and muscle SWS, were compared between the two groups using Student’s t test or Fisher's exact test. Pearson correlation analyses were conducted for the variables of IRD, muscle thickness, and SWS in the 36 DRA patients. Results The maximum diameter of recti abdominus separation was located at the umbilicus in DRA patients (4.59 ± 1.14 cm). The SWS value was significantly lower in the RA (p = 0.003) and higher in the TrA muscle (p < 0.001) in DRA patients compared with the age-matched controls. However, SWS in both muscles (RA and TrA) showed a statistically positive correlation with IRD (p < 0.05). In addition, the SWS value in EO statistically decreased in DRA patients compared with the healthy controls (1.65 ± 0.15 vs. 1.79 ± 0.14, p = 0.001). Conclusions The application of SWE to abdominal wall muscles in DRA patients is feasible. The correlation between SWS value and IRD in RA should be interpreted with caution.

“…It may be related to the contractility of deltoid muscle; This is needed to be further studied [26][27][28]. These ndings are clinically valuable because most previous SWE studies were designed to test diagnostic performance for various pathologies without speci cally focusing on possible variations induced by different shoulder abduction positions [29][30][31].…”

Background: To measure the middle deltoid (MD) muscle elasticity during different shoulder abduction in healthy participants using shear wave elastography (SWE) and analyze the factors that may affect the MD elasticity, and then to establish the reference ranges of the normal MD elasticity during different shoulder abduction. Methods: Mean shear wave velocity (SWV) of the MD in 70 healthy participants were evaluated at left and right shoulder 0° and 90° abduction (L0°, R0°, L90°, R90°) using SWE, and potential factors that may affect MD elasticity including gender, MD thickness, age, body mass index were analyzed. Normal reference ranges of MD elasticity were calculated using normal distribution method. Results: Mean SWV was statistically significantly higher at L90° than L0°, higher at R90° than R0°, higher at R0° than L0°, and higher at R90° than L90° (all p< 0.0001). Mean SWV was significantly higher in males at both L0° (p< 0.05) and R0° (p< 0.01) than in females. Neither MD thickness, age nor body mass index influenced MD elasticity. Normal reference ranges of the MD elasticity were 2.4-3.1 m/s in males and 2.2-2.9 m/s in females at L0° and 2.5-3.3 m/s in males and 2.4-3.2 m/s in females at R0°, and were 4.9-6.7 m/s at L90°, 5.2-7.1 m/s at R90° for both males and females. Conclusions: Our results suggest that the normal MD elasticity at L0°, R0°, L90°, R90° are different and gender should be considered when determining the reference ranges of normal MD elasticity at L0° and R0° with SWE. These values may provide quantitative baseline measurements for assessment of the normal MD elasticity.

“…Third, the 4-point measurement method we applied enabled us to obtain higher values than the 2-point measurement method utilized in previous literature because of the possibility of joint decision-making. Fourth, in theory, patients with high BMI may have more variability in the measurement of abdominal wall muscle SWS due to thicker subcutaneous fat ( 22 ). Since the BMI of all the patients included in our study was <30 kg/m 2 , with an average of 24.11 ± 2.68 kg/m 2 , the accuracy and stability of SWS detection may be better, suggesting higher reliability.…”

This study aimed to assess the thickness and shear wave speed (SWS) of the anterolateral abdominal wall muscles in female patients with incisional hernias of different widths, in order to analyze the biomechanical properties of abdominal wall muscles. This study included 53 patients with incisional hernia (Group A [hernia width <4 cm]: 21 patients, Group B [hernia width ≥4 cm]: 32 patients). The muscle thickness and SWS values of the external oblique (EO), internal oblique (IO), and transversus abdominis (TrA), and the hernia width were measured using Siemens Acuson S2000 ultrasound systems. Four detection points were labeled on the anterolateral abdominal wall: points 1, 2, 3, and 4, corresponding to the upper right, upper left, lower right, and lower left, respectively. The muscle thickness of the IO at point 3 was significantly different between both groups (p = 0.024). Group B had significantly higher SWS values than Group A, especially for the EO (points 1, 2, and 3), IO (points 1 and 2), and TrA (points 2 and 4) (p < 0.05). Pearson correlation analysis shows no significant correlation between muscle thickness and the SWS values of EO, IO, and TrA (all p > 0.05). Linear correlation analysis showed a significantly positive correlation between hernia width and the mean SWS value of EO, IO, and TrA (p = 0.004, 0.005, and 0.043, respectively). Muscle thickness was not reliable measure to directly reflect the biomechanical changes of the abdominal wall muscles in patients with incisional hernia. Comparatively, SWE can accurately measure the stiffness of the abdominal wall muscles and intuitively evaluate its biomechanical properties.
