“…The participants were asked to hold a gel bottle so that the hand was in supination and their arm would not inadvertently internally rotate. The distance between the participants' acromioclavicular joint and the cubital fossa was measured, and the 75% distance was marked on their arms with a skin-safe marker to indicate the site of measurement with the least variability [14]. The right arm was assessed first with the elbow in full extension at 0 • flexion, then with the forearm resting on a 30 • wedge, and then on a 60 • wedge, as is shown in Figure 1.…”

The Shear Wave Elastography of muscles can provide real-time information on the stiffness of muscles; however, the difference in stiffness between biceps brachii muscle bellies requires more research. Understanding the variables that affect muscle stiffness will assist in the development of Shear Wave Elastography as a diagnostic tool for muscle stiffness pathologies. This study’s aim is to determine the Shear Wave Velocity of the short and long head of biceps brachii and the change in stiffness with elbow flexion to create a reliable protocol for pathological muscle assessment. The muscle belly of the short and long heads of bilateral biceps brachii of 38 healthy participants were scanned supine with the arm at full extension and at 30° and 60° elbow flexion. A log transform of the SWV was used as the response variable in the regression analysis, and the intraclass correlation coefficient was determined for reliability. The Shear Wave Velocity of the short head was lower than the long head on average. By fitting Bayesian mixed effect regression models to the data, the estimated posterior predictive mean velocities for the short head at full extension, 30°, and 60° were 3.14 m/s, 2.65 m/s, and 2.62 m/s, respectively; and 3.91 m/s, 3.02 m/s, and 3.15 m/s, respectively, for the long head of the biceps brachii. The intraclass correlation coefficients (0.64–0.92) were good to excellent. Shear Wave Elastography can detect the consistent difference in the stiffness of the two muscle bellies of the biceps brachii at multiple elbow angles. The assessment of muscle stiffness with Shear Wave Elastography should consider the morphology of the muscles.

“…There are already many approaches for the use of ultrasound in the assessment of tissue rheological properties [ 67 ], the most widely used being the supersonic shear wave imaging (SSI) [ 68 ]. The method has so far been attributed with a variable reliability ranging between 0.67 and 0.92 (95% CI Avg , see Table 1 ) by various studies [ 33 , 40 , 41 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 ].…”

“Muscle tone” is a clinically important and widely used term and palpation is a crucial skill for its diagnosis. However, the term is defined rather vaguely, and palpation is not measurable objectively. Therefore, several methods have been developed to measure muscle tone objectively, in terms of biomechanical properties of the muscle. This article aims to summarize these approaches. Through database searches, we identified those studies related to objective muscle tone measurement in vivo, in situ. Based on them, we described existing methods and devices and compared their reliability. Furthermore, we presented an extensive list of the use of these methods in different fields of research. Although it is believed by some authors that palpation cannot be replaced by a mechanical device, several methods have already proved their utility in muscle biomechanical property diagnosis. There appear to be two issues preventing wider usage of these objective methods in clinical practice. Firstly, a high variability of their reliability, and secondly, a lack of valid mathematical models that would provide the observed mechanical characteristics with a clear physical significance and allow the results to be compared with each other.

Background Ultrasound Shear Elastography (USE) is used to quantify the stiffness of biological tissues by measuring muscle deformation or displacement. Compression Elastography (CE) involves applying pressure to the skin using an ultrasound (US) transducer, resulting in tissue displacement, and is used to assess tissue stiffness based on the principle that compression produces strain. Methods In this study, we estimated the strain in the biceps brachialis of healthy volunteers (n=11) and patients with post-stroke spasticity (n=2). The arms were evaluated using the Tardieu scale and strain measurements were obtained using an ultrasound probe with the elbow flexed at 30°. A semi-automatic algorithm for muscle thickness measurement was employed to qualitatively measure muscle elasticity. The application of controlled pressure from an electromechanical actuator allows for strain estimation without direct intervention by an operator, thereby reducing subjectivity in the results. The main aim of this study was to utilize CE to characterize the normal range of muscle elasticity in the biceps brachialis of healthy volunteers who exhibited no changes and were rated 0 on the modified Tardieu scale. Results The normal range of strain for both healthy male and female volunteers demonstrated an acceptable deviation for each strain measurement, as the standard deviation was considered small and relatively constant (with higher values observed under maximum pressure). The proposed measurement mechanism is sensitive, allowing for the observation of strain differences between healthy and spastic muscles in both men and women. Conclusions Comparison of the average curve for the healthy group with two examples of curves from individuals with spasticity showed evident differences. Thus, it would be worthwhile to continue this research by evaluating a group of subjects with spastic muscles.
