Background: Although the shoulder range of motion significantly decreases with advancing age, how the natural aging process affects the joint capsule, including the Coracohumeral Ligament (CHL), in healthy subjects is still unknown. Objective To use shear wave elastography to investigate the correlations between age, sex, and shoulder dominance, and elasticity of the CHL in healthy individuals. Methods: Eighty-four healthy volunteers (mean age: 42.6; 39 men) were included in this study. They were divided into five groups based on age: 20s (20–29, n = 19), 30s (30–39, n = 17), 40s (40–49, n = 20), 50s (50–59, n = 13), and 60s (60–69, n = 15) groups. The elasticity of the CHL in the bilateral shoulders was evaluated at the neutral and 30° external rotation (ER at 30°) positions with the arm at the side while laying supine. Results: The elastic modulus was significantly greater in ER at 30° than in the neutral position regardless of sex or shoulder dominance (P < 0.001). Significant positive correlations between age and elasticity of the CHL were observed in both the neutral and ER at 30° positions regardless of shoulder dominance. Elasticity of the CHL was significantly greater with increasing age in both the neutral and ER at 30° positions on the dominant (P = 0.0022, P < 0.001, respectively) and non-dominant sides (P = 0.0199, 0.0014). Conclusion: The elasticity of the CHL increased with age, and the ER at 30° position could demonstrate faint changes in CHL elasticity. Level of Evidence: Level 3 Case-control study.

Coracohumeral Ligament

Context: Range of motion (ROM) in the glenohumeral joint decreases with age in healthy subjects; however, the underlying mechanism remains unclear. The process of aging of the joint capsule, including the coracohumeral ligament (CHL), could affect ROM limitation. Objective: This study investigated correlations between elasticity of the CHL, evaluated by means of shear-wave elastography, and age, side dominance, and ROM in healthy individuals. Design: Experimental study. Setting: Laboratory. Subjects: Eighty-four healthy volunteers (39 men and 45 women, mean age: 42.6 y) were included. Main Outcome Measures: Subjects were divided into 3 age groups: younger (20–39 y), middle (40–59 y), and older (≥60 y) age groups. With participants in the supine position, CHL elasticity in both shoulders was evaluated in both neutral and 30° external rotation, with arms at the sides. ROM, including forward flexion, lateral elevation, external rotation, 90° abduction with external rotation, and hand behind the back were measured with participants in the standing position. Results: The CHL elastic modulus was higher in the older group than in the younger group in the neutral (78.4 kPa [SD: 37.1] and 56.6 kPa [SD: 31.7], respectively) and 30° external rotation positions (135.5 kPa [SD: 63.5] and 71.4 kPa [SD: 32.2], respectively). Negative correlations were found between the CHL elastic modulus and ROM in terms of 30° external rotation and both external rotation (R = −.59, P = .02) and 90° abduction with external rotation (R = −.71, P = .003) in the older group, with correlation coefficients increasing with age. Conclusions: Significant correlations were identified between CHL elasticity and ROM in both external rotation and 90° abduction with external rotation with increasing age. Decreased CHL elasticity was strongly associated with decreased shoulder ROM in middle-aged and older individuals.

The scapulohumeral pain syndrome (frozen shoulder) is an umbrella term for various pathological conditions characterized by pain and limited range of motion in the shoulder joint that considerably reduces a person’s ability to work and impairs the quality of life. The most common etiological factors are: load on the muscles of the shoulder girdle, traumatic injuries of the shoulder joint in patient’s history and overstretching and partial tearing of the ligaments of the shoulder joint, vertebral radiculopathy with the development of reflex and dystrophic disorders in the corresponding muscles, ligaments and joint capsule. The goal of our work was to compare the efficacy of the rehabilitation plans based on standard approaches and rehabilitation plans based on the theory of muscle spirals in patients with the severe pain syndrome and scapulohumeral periarthritis. Materials and methods. We studied 98 patients with scapulohumeral periarthritis. At the first stage of the treatment, all patients received a medical blockade in sites of marked inflammation of para-articular structures. Then, the patients were divided into 2 groups: the patients of group I received a standard rehabilitation in accordance with the recommended regimens using physiotherapy and exercise therapy. The patients of group II took the patient-centred rehabilitation course based on the theory of muscle spirals and the complex effect on spastic muscles. Pain intensity was assessed by visual analogue scale and DASH scale, muscle stiffness was evaluated by compression and shear wave elastography. Results and conclusions. The dynamic changes of pain reduction in patients of group II demonstrated the significant intensity of pain, and a rapid restoration of joint function. The findings of shear wave elastometry showed no difference between the stiffness of the shoulder muscles in the group II after the course of rehabilitation and healthy muscles. Thus, the use of patient-centred rehabilitation plans based on the theory of muscle spirals and a complex effect on spastic muscles enables to achieve a more pronounced effect compared to the standard rehabilitation approaches.

Liver Elastography

Abstract Purpose Liver elastography is increasingly being applied in screening for and follow-up of pediatric liver disease, and has been shown to correlate well with fibrosis staging through liver biopsy. Because time is of the essence when examining children, we wanted to evaluate if a reliable result can be achieved with fewer acquisitions. Materials and Methods 243 healthy children aged 4–17 years were examined after three hours of fasting. Participants were divided into four age groups: 4–7 years; 8–11 years; 12–14 years and 15–17 years. Both two-dimensional shear wave elastography (2D-SWE; GE Logiq E9) and point shear wave elastography (pSWE; Samsung RS80A with Prestige) were performed in all participants, while transient elastography (TE, Fibroscan) was performed in a subset of 87 children aged 8–17 years. Median liver stiffness measurement (LSM) values of 3, 4, 5, 6, 7, and 8 acquisitions were compared with the median value of 10 acquisitions (reference standard). Comparison was performed for all participants together as well as within every specific age group. We investigated both the intraclass correlation coefficient (ICC) with absolute agreement and all outliers more than 10 %, 20 % or ≥ 0.5 or 1.0 kPa from the median of 10 acquisitions. Results For all three systems there was no significant difference between three and ten acquisitions, with ICCs ≥ 0.97. All systems needed 4 acquisitions to achieve no LSM deviating ≥ 1.0 kPa of a median of ten. To achieve no LSM deviating ≥ 20 % of a median of ten acquisitions, pSWE and TE needed 4 acquisitions, while 2D-SWE required 6 acquisitions. Conclusion Our results contradict recommendations of 10 acquisitions for pSWE and TE and only 3 for 2D-SWE.

Examination Technique

There has been great interest in the development of non-invasive techniques for the diagnosis of liver fibrosis in chronic liver diseases, including ultrasound elastographic methods. Some of these methods have already been adequately studied for the non-invasive assessment of diffuse liver diseases. Others, however, such as two-dimensional Shear Wave Elastography (SWE), of more recent appearance, have yet to be validated and some aspects are for the moment incompletely elucidated. This review discusses some of the aspects related to two-dimensional SWE: the examination technique, the examination performance indicators, intra and interobserver agreement and clinical applications. Recommendations for a high-quality examination technique are formulated. Key words:  –  –  – Two-dimensional Shear Wave Elastography.
