“…Lima et al reported that the elasticity of the MG was not correlated to ankle plantar flexion strength. 28 Csapo et al described no correlations between muscle strength and total amount of non-contractile tissues within the triceps surae. 24 Accordingly, muscle strength might not contribute to muscle elasticity, which reflects the amount of non-contractile tissues.…”

Aim To clarify the age‐related changes in muscle elasticity or thickness of the lower extremities in older women, and to analyze their relationship with physical functions. Methods The muscle elasticity and thickness of the rectus femoris and medial head of the gastrocnemius of 102 young women (young group) and 221 elderly women (elderly group) were measured using ultrasonography. In the elderly group, physical functions, including knee extension strength, Timed Up and Go test, single‐leg standing, maximum gait speed and Four Square Step Test were also measured. Results The elasticity of the rectus femoris and medial head of the gastrocnemius were significantly higher, but the muscle thickness of both muscles was significantly lower in the elderly group than in the young group (both P < 0.001). In the elderly group, the elasticity of the rectus femoris was significantly correlated with Timed Up and Go test, maximum gait speed and Four Square Step Test (ρ = 0.481, r = −0.387 and ρ = 0.401, respectively, all P < 0.001), and the medial head of the gastrocnemius was similar (ρ = 0.471, r = −0.489 and ρ = 0.422, respectively, all P < 0.001). The muscle thickness of the rectus femoris was significantly associated with knee extension strength (r = 0.444, P < 0.001). Conclusions Older women showed age‐related changes in high elasticity and atrophy of the rectus femoris and medial head of the gastrocnemius. The high elasticity of both muscles, not muscle thickness, was associated with dynamic balance and walking ability. Geriatr Gerontol Int 2019; 19: 61–65.

“…This is in accordance with studies investigating the relationship between muscle strength and elastic properties. Lima ( 22) used elastography to compare elastic properties of the gastrocnemius and soleus muscles to force generated by them (22). They concluded that elasticity of these muscles does not correlate to force.…”

Objective. Calf strain occurs frequently in tennis players and has been termed "tennis leg". To date, there is a lack of information showing how injury history, age, gender, or level of play, may predispose tennis players to injury (1, 2). The purpose of this study was to investigate the elastographic properties of the gastrocnemius-soleus complex in a group of club-level tennis players. We hypothesized that elastographic properties of the gastrocnemius-complex are affected by age and sport specificity (tennis only vs multi-sport). Methods. Participants were recruited through contact personnel of a local tennis club. At the club's annual summer tournament, each participant voluntarily consented and completed a survey to obtain information about age, level of play, length of play, participation in other sports, relevant injuries, and relevant surgeries. Participants underwent ultrasonography that included visualization of the medial gastrocnemius musculotendinous junction, soleus muscle, and Achilles tendons, bilaterally. Shear wave speed (SWS) was gathered from ultrasonography for all tissues to provide a comparative standard unit of measurement. The data was analyzed with a mixed effects model. Results. 20 participants with mean age 33.5 years old (range, 14-61) were evaluated. There was a statistically significant trend in medial gastrocnemius SWS depending on age, participation in sports other than tennis, and two different metrics for skill level (highest level of competitive play and USTA NTRP rating). There was a statistically significant trend between Achilles tendon SWS and highest level of competitive play. Results showed no significant trends for any of the tissues and serving hand, whether the ultrasound was conducted before or after a match, or for any of the four metrics for tennis experience (times playing tennis per week, overall tennis experience, years playing > 3 times per week, and whether a player had > 10 or < 10 years of experience). No statistically significant trends were observed for the soleus muscle when compared to any of the demographics. Conclusions. Age, exclusively playing tennis as opposed to other sports, and two metrics of skill level (highest level of competitive play and USTA NTRP rating) significantly affected gastrocnemius SWS. Highest level of competitive play was the only metric found to affect Achilles tendon SWS. Soleus SWS exhibited no significant changes with any of the variables, despite following similar trends with gastrocnemius SWS.

“…Results were grouped according to the type and mode of action of elastography for better homogeneity and consistency within the results. Of the 21 articles included, seven articles investigated strain elastography where strain ratio was calculated as a semi-quantitative measure of stiffness [27,[32][33][34][35][36][37], eleven investigated shear wave imaging presenting results as either shear wave velocity (SWV) [28-30, 38-40, 47] or modulus [31,[41][42][43], two investigated continuous shear wave elastography (cSWE) [44,45], while the last article assessed threedimensional shear wave elastography (3D SWE) [46]. A summary of the overall quality ratings for the measurement properties of each elastography method and their statistical results are reported in Table 4 and Table 5.…”

Background Managing and rehabilitating Achilles tendinopathy can be difficult, and the results are often unsatisfactory. Currently, clinicians use ultrasonography to diagnose the condition and predict symptom development. However, relying on subjective qualitative findings using ultrasound images alone, which are heavily influenced by the operator, may make it difficult to identify changes within the tendon. New technologies, such as elastography, offer opportunities to quantitatively investigate the mechanical and material properties of the tendon. This review aims to evaluate and synthesise the current literature on the measurement properties of elastography, which can be used to assess tendon pathologies. Methods A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. CINAHL, PubMed, Cochrane, Scopus, MEDLINE Complete, and Academic Search Ultimate were searched. Studies assessing the measurement properties concerning reliability, measurement error, validity, and responsiveness of the instruments identified in healthy and patients with Achilles tendinopathy were included. Two independent reviewers assessed the methodological quality using the Consensus-based Standards for the Selection of Health Measurement Instruments methodology. Results Out of the 1644 articles identified, 21 were included for the qualitative analysis investigating four different modalities of elastography: axial strain elastography, shear wave elastography, continuous shear wave elastography, and 3D elastography. Axial strain elastography obtained a moderate level of evidence for both validity and reliability. Although shear wave velocity was graded as moderate to high for validity, reliability obtained a very low to moderate grading. Continuous shear wave elastography was graded as having a low level of evidence for reliability and very low for validity. Insufficient data is available to grade three-dimensional shear wave elastography. Evidence on measurement error was indeterminate so evidence could not be graded. Conclusions A limited number of studies explored quantitative elastography on Achilles tendinopathy as most evidence was conducted on a healthy population. Based on the identified evidence on the measurement properties of elastography, none of the different types showed superiority for its use in clinical practice. Further high-quality studies with longitudinal design are needed to investigate responsiveness.
