“…For skeletal muscles, we recommend the SWV as a surrogate for muscle elasticity instead of the Young's modulus. This will help with reliability of study results and allow more accurate comparison between studies [18,32,34]. Reviewing the literature on muscle SWE, we found that most studies performed SWE in a shoulder abduction position because of the time limitations.…”

“…Particularly, gender had impact on MD elasticity at both L0° (P< 0.05) and R0° (P< 0.01) in the present study, maybe indicating there is a signi cant difference in the MD elasticity between genders during shoulder 0° abduction. A possible explanation for this discrepancy may be the obvious difference in the MD muscle size and composition between genders at shoulder 0° abduction [16][17][18][19][20]. Haizlip et al [21] showed that collagen and elastin architectures of muscle bers mainly determined MD elasticity, which may vary between different gender.…”

“…Deltoid, an important motor muscle of shoulder, plays a vital role in maintaining shoulder stability [3]. The change in elasticity of deltoid may result in imbalance of the scapular force and cause shoulder pain [4]. Middle deltoid (MD) is an important component of deltoid, whose muscle bers are parallel and easy to be measured.…”

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.

“…The new technique called SWE can quantitatively re ect biomechanics changes of muscles contractility. Increased muscle elasticity during shoulder active abduction, resulting from muscle contraction, is an especially exciting area for clinical integration of ultrasound elastography [6,12,24]. Firstly, it may be the rst study to quantitatively assess normal MD elasticity by measuring the SWV during different shoulder active abduction.…”

“…Shear wave elastography (SWE) as a new ultrasound-based elastography technique, quantitatively providing the biomechanics parameters of the muscles such as muscle elasticity, has good repeatability and reproducibility [10][11]. Excellent reliability and feasibility for assessing the deltoid using SWE were reported [4,[12][13]. SWE can quantitatively evaluate muscle elasticity through elastic parameters such as shear wave velocity (SWV) and Young's modulus [10,14].…”

Background: To measure the middle deltoid (MD) elasticity in healthy participants during different shoulder abduction (with bilateral shoulder in 0 degree abduction and 90 degree active abduction) using shear wave elastography (SWE) and analyze the factors that may affect the MD elasticity, and the objective of this study is to establish the reference ranges of normal MD elasticity during different shoulder abduction by using SWE. Methods: Mean shear wave velocity (SWV) of the MD in 70 healthy right-handed participants (35 females, 35 males) were evaluated using SWE during different shoulder abduction, and potential factors that may affect MD elasticity including gender, MD thickness, age, body mass index were analyzed. Different shoulder abduction positions of each participant were as follows: (i) 0° abduction of bilateral shoulder (L0° and R0°), (ii) 90° active abduction of bilateral shoulder (L90° and R90°). Reference ranges of normal MD elasticity were calculated using normal distribution method. Results: Mean SWV was 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°, and R90° with SWE are different. A separate reference range of normal MD elasticity at L0°, R0°, L90°, and R90° should be used. Moreover, the reference ranges of normal MD elasticity at L0° and R0° shoulder be divided by gender. These values may serve as quantitative baseline measurements for assessment of normal MD elasticity.

ObjectiveThis study aimed to evaluate normal supraspinatus (SS) muscle elasticity using shear wave elastography (SWE) in an asymptomatic group, analyze its correlation with demographic factors and ultrasound (US) grayscale grade, and compare the elasticity between normal SS muscles and symptomatic SS muscles with tendon tears.MethodsA prospective study was conducted with 101 adult patients with normal SS muscle scheduled for surgery due to a contralateral shoulder with SS tendon tear. Both shoulders underwent US examinations, including SWE. The SWE values, including mean and median elasticity, as well as the elasticity ratio, were analyzed for their correlation with demographic characteristics and grayscale grades. A comparison of SWE values was performed between the normal and symptomatic SS muscle groups.ResultsThe mean SWE modulus of the normal SS muscle was 27.87 kPa (±49.04), with an elasticity ratio of approximately 1.52 (±0.03). Males exhibited slightly higher elasticity ratios compared with females (1.61 vs 1.45, P = .016). The interobserver agreement for all SWE measurements was excellent (>0.8). Grayscale grade increased with age, showing a similar pattern in females (P < .001). However, no significant correlation was observed between SWE values and grayscale grade in the normal SS muscle group. SWE values in normal SS muscles were significantly lower than those with tendon tears (P < .001).ConclusionsSWE provides objective measurements of normal SS muscle elasticity. Gender‐based variations were observed, with males exhibiting slightly higher elastography ratios. SWE values were significantly lower in asymptomatic SS muscles compared with those with tendon tears.
