“…The ability to detect SE differences of quadriceps and patellar tendon between asymptomatic and KOA individuals may offer earlier opportunity to deliver enhanced rehabilitation strategies. To date, mixed results in relation to superiority of SE techniques exist [35,36], however, our findings [20]. Reduced DQT elasticity in the KOA population compared to the AC group (p = 0.033, Tables 2, 3) may be a particularly valuable finding due to previous association with reduced quadriceps muscle strength and reduced rate of force development in KOA [5,37], and the functional role of the muscle tendon interface [6].…”

“…To date, mixed results in relation to superiority of SE techniques exist [ 35 , 36 ], however, our findings demonstrate potentially clinically important and statistically significant differences between groups in both CS and ER techniques. Nevertheless, recent meta-analyses recognise that SE remains largely unstandardised and further work is required to minimise bias and improve reliability [ 20 ].…”

“…SE has potential for the detection and monitoring of tendon alterations [ 19 ], therefore, an understanding of knee tendon elasticity changes in KOA may be of benefit to inform early intervention such as targeted rehabilitation. A recent systematic review reports high variability in the quality of many existing knee tendon SE studies [ 20 ]. Our previous work provides evidence of reliability of a standardised SE technique when performed and interpreted by an experienced operator.…”

An advanced ultrasound imaging technique, sonoelastography (SE) is used to evaluate tissue elasticity. To determine SE potential to detect pathological-related changes, and characteristics related to tendon pathology we aimed to (1) compare quadriceps and patellar tendon findings in individuals with knee osteoarthritis (KOA) and asymptomatic older adults (AC), and (2) explore associations between SE, participant characteristics (age, BMI, and leg circumference) and KOA status. 84 participants (47; KOA and 37; asymptomatic older adults) underwent SE examination of quadriceps (distal) and patellar (distal, proximal) tendon in a supine position with the knee bent at 30°. Colour score (CS) and Elasticity Ratio (ER) analysis were performed by a blinded experienced operator using Esaote Mylab 70 XVG Ultrasound equipment. Significantly reduced elasticity in the distal quadriceps (median (IQR) 2(2), 3(1), p = 0.033 for KOA and AC, respectively) and proximal patellar (3(1), 3(0), p = 0.001) tendons and more elastic distal patellar (1.50 (0.55), 1.87 (0.72), p = 0.034) tendons were observed in the KOA group. Significant associations) were identified between SE and participant BMI (Rs = − 0.249–0.750, p < 0.05) and leg circumference (Rs = − 0.260–0.903, p < 0.05). Age, BMI and KOA status, were independent explanatory variables of SE CS findings at the distal quadriceps tendon patellar tendon, proximal patellar tendon and distal patellar tendon, explaining 66%, 81% and 64% of variance, respectively. Age, BMI and KOA status were independent explanatory variables of SE ER findings at the distal patellar tendon explaining 19% of variance. Potentially clinically relevant altered tendon stiffness were observed between individuals with KOA and asymptomatic controls. Key KOA risk factors and participant characteristics explained variance in tendon stiffness. Findings provide context for future studies to investigate the potential for targeted SE detected early clinical management based on associated participant characteristics.

“…Obst et al (14), in their meta-analysis study, showed that the SWE (kPa) in patellar tendinopathy cases increased at 30 degrees both globally and locally in the proximal compared to the normal tendon, while at 0 degrees, the values were found to be lower than usual. Also, on the other hand, patellar tendinopathy study numbers were lower than Achilles tendinopathy studies (23). In this context, only three studies evaluated reproducibility among clinicians on the patellar tendon, and the ICC value varied from 0.71 to 0.97 (24)(25)(26).…”

To evaluate the reproducibility of shear-wave elastography, thickness, power doppler, and hypoechoic region assessments taken from the different parts of the patellar tendon among sports medicine clinicians. Twenty-one healthy, physically active individuals with dominant legs were included in the study. Shear-wave elastography, thickness, power doppler, and hypoechoic area assessment were evaluated from the proximal, middle, and distal part of the tendon both at 30-degree knee flexion and full extension. To evaluate the reproducibility within and among clinicians, the same measurements were performed at 4-7 days intervals. Evaluations of intra-and inter-rater reliability for examiners I and II were conducted via two-way random effects and absolute agreement type intraclass correlation coefficient (ICC). Gwet's AC1 (GC) agreement coefficient was used to evaluate categorical data agreement. The intra-rater reliability of both sports physicians on shear-wave elastography was in good to excellent reproducibility in all three parts at the 0-30-degree measurements (intra-observer ICC: 0.60-0.88, inter-observer ICC: 0.67-0.87). Similar results were obtained for the thickness (intra-observer ICC: 0.83-0.94, inter-observer ICC: 0.65-0.83). As a result of the power doppler taken at two different angles were excellently (intra-observer GC: 0.86-1.00, inter-observer GC: 0.86-1.00) consistent both within and among the clinicians but not for the hypoechoic region evaluation (intra-observer GC: 0.58-1.00, inter-observer GC: 0.40-1.00). This study shows that the reproducibility of local measurements made in different parts of the patellar tendon at two different angles within and among sports medicine physicians is at a good to an excellent level.

“…For this reason, an interobserver reproducibility evaluation was unavailable. However, the intra-rater reliability of repeated measurements of US parameters ranged from 0.895 to 0.910, which indicates “good” to “excellent” reliability [30] . Second, given the retrospective nature of the study, there were some difficulties during the collection of comprehensive information from the medical chart.…”

The purpose of this study was to investigate the upper trapezius muscle thickness (UTMT) in congenital muscular torticollis (CMT) patients and determine the correlation among sternocleidomastoid muscle thickness (SCMT), accessory nerve (AN) cross-sectional area (CSA), and UTMT in CMT. This retrospective study consisted of 2 participant groups: Group 1 (SCM mass CMT, n = 20) and Group 2 (Postural CMT, n = 22). For both groups, B-mode ultrasound was performed by a physiatrist to measure the SCMT and UTMT and calculate the CSA of the AN. The correlation among SCMT, CSA of the AN, and UTMT in both groups was evaluated. The between-group comparison revealed that Group 1 had significantly greater SCMT, UTMT, and CSA of the AN on the affected side than Group 2 ( P < .05). The intragroup comparison between the affected and unaffected sides also revealed that, in Group 1, the SCMT, UTMT, and CSA of the AN were significantly higher on the affected side than on the unaffected side ( P < .05), whereas no significant differences were observed in Group 2. In Group 1, a positive correlation ( r = 0.55) was observed between the UTMT and CSA of the AN on the affected side, but not observed between the SCMT and CSA of the AN. The findings of the study indicate that sternocleidomastoid muscle size may impact the thickness of the upper trapezius muscle via the accessory nerve in patients with congenital torticollis.
