“…The validity was confirmed throughout the full normal range of tension for appendicular skeletal muscle [13]. The reliability of the SWE for assessing muscle stiffness has been shown to be good or excellent for several muscle groups, including lower limb [5,11,12,14], trunk [4,10] and upper limb muscles [3,[6][7][8][9]. It has been suggested that SWE could also be used to monitor muscle activity [9,12,15,16].…”

“…In another study, a wide range of average activity of the trapezius during 30-min office (0.5-9.3% MVC) or light manual work (0.6-12.5% MVC) was reported, with no difference between the work types [33]. Previous research has also suggested differences in trapezius muscle stiffness (assessed by SWE) between the dominant and non-dominant side of the body during rest [6], while no differences in upper trapezius activity between body sides were recorded during computer-based tasks [34].…”

“…The choice of body site to conduct a measurement may be an important factor of shear modulus score. For instance, higher shear modulus values were reported on the dominant side, compared to non-dominant side for the trapezius muscle [6]. On the other hand, studies exploring lower limb muscles have not reported such differences [12,14].…”

The shear modulus obtained with SWE has been validated for assessing muscle stiffnes, by using isolated meat speciments and comparing it to direct mechanical stiffness measures.…”

Shear-wave elastography has been recognized a useful tool for quantifying muscle stiffness, commonly reported as shear modulus, however the reports on reliability are often limited to test-retest correlations. In this study, we explored the reliability of shear-wave elastography for assessment of the trapezius muscle stiffness and its relationship with lowlevel muscle activity. Methods Twenty participants were included in a two-session experiment. Measurements of shear modulus and muscle activity were performed at rest and during low-level activity, induced by shoulder abduction without additional external resistance. Results Good to excellent intra-session repeatability (ICC > 0.80) and moderate inter-rater and inter-session reproducibility (ICC = 0.66-0.74) were observed. Typical errors were acceptable (7.6% of the mean value) only for intra-session measurements in resting conditions, but not acceptable for all conditions with low-level muscle activity (10.2-16.6% of the mean value). Inverse relationships between shear modulus and muscle activity at 40˚and 60˚of shoulder abduction (r =-0.53 and-0.57) were observed on a group level. We also found higher shear modulus in males compared to females, for the parallel probe position compared to the perpendicular position (in relation to muscle fiber orientation), and for the dominant side of the body compared to the non-dominant side. Conclusions This study showed an inverse relationship between muscle activity in low-level range and shear modulus on a group level, suggesting inherent passive stiffness could account for a larger portion of the variance (compared to muscle activity) in shear modulus when the

IntroductionThe deltoid muscle plays an essential role for the postoperative functional outcome after reverse shoulder arthroplasty. Ultrasound elastography is areliable method for detecting soft tissueproperties and their changes due to different conditions or pathologies. Tissue stiffness is calculated after application of an acoustic impulse (acoustic radiation force impulse, ARFI), which deforms the underlying tissue. The purpose of this study was to evaluate changes in the deltoid muscle tissue after RSA and reveal a correlation to the functional outcome.Material and methods18 patients treated with reserve shoulder arthroplasty after proximal humeral fracture or cuff arthropathy were included. Shear wave elastography was performed on both sides of three regions of the deltoid muscle. Functional outcome was recorded by VAS, CMS, range of motion and strength (flexibar). Statistical analysis was performed by SPSS.ResultsThe functional outcome was satisfactory (VAS pain: 18 points, VAS function: 64 points, Constant Murley: 66 points). Force was reduced to 48.8N after RTSA in comparison to 58.3 N on the healthy side (p> 0.07). SWE was able to show a higher overall muscle tension of the deltoid in patients after RSA compared to the contralateral non-operated side. The differences were particularly visible in the anterior and middle deltoid region. Under isometric load all deltoid regions showed significantly increased tension, which was particularly eminent in the anterior region of the pars clavicularis.ConclusionShear wave elastography is a reliable method for detecting changes of tension in the deltoid muscle after RTSA and shows a higher tension of all areas of the deltoid, especially prominent in the anterior and middle portion of the deltoid. Future application possibilities are monitoring of deltoid vitality, preoperative assessment and intraoperative management.Level of evidence: diagnostic study, Level III
