“…The transducer was placed on the longitudinal axis of the tendon, between the insertion point of the tendon with the calcaneus and the muscle-tendon junction. Similar to previous studies, 4,7,9,30 the thickness of the Achilles tendon was measured at the points 2 and 3 cm proximal to the superior aspect of the calcaneus (Figure 1A). The measurements of the patellar tendon were carried out when the participants were in the supine position with 30 degrees of knee flexion.…”

Background: Changes in lower extremity alignment in individuals with flatfoot may be associated with differences in morphology of the tendons or cartilage in lower extremities. The purpose of the present study was to investigate the potential association of flatfoot with the morphology of the Achilles tendon, patellar tendon, and femoral cartilage. Methods: This study was conducted with 40 participants with flatfoot (28 females, 12 males) and 40 participants with a normal foot posture (28 females, 12 males). The thickness of the Achilles tendon (at points 2 and 3 cm proximal to the superior aspect of the calcaneus), patellar tendon (at the inferior pole of the patella and 1 cm proximal of the inferior pole of the patella), and femoral cartilage (at the intercondylar area, medial condyle, and lateral condyle) was measured by an ultrasonography device. Results: The Achilles tendon thickness at 2 cm ( P = .009) and 3 cm ( P = .010) proximal of the superior aspect of the calcaneus was on average 4% to 6% lower in individuals with flatfoot compared with controls. The cartilage thickness at the intercondylar area ( P = .005) and medial condyle ( P = .018) was on average 8% to 12% greater in individuals with flatfoot; however, the cartilage thickness at the lateral condyle and patellar tendon thickness was similar in both groups. Conclusion: The results obtained suggest that foot posture is associated with the morphology of the Achilles tendon and femoral cartilage. Level of Evidence: Level III, diagnostic comparative study.

Rehabilitative ultrasound imaging for the assessment of selected morphometric parameters of the flexor hallucis longus muscle in healthy individuals: An inter- and intra- rater reliability study

et al. 2021

IntroductionUltrasound imaging (USI) is useful to evaluate structures of the foot to guide treatment, but the reliability of USI technique needs to be clarified. The goal of the study was to evaluate the intra- and inter-examiner reliability of USI image capture, and measurement of the cross-sectional area (CSA) and thickness of the flexor hallucis longus (FHL) for experienced and novice examinersMaterial and methodsFHL images were captured for 20 healthy adults. Reliability of image capture was evaluated between images repeated at 10-min interval for an experienced and a novice examiner. Reliability of image-based measurements was evaluated for one experienced and one novice rater, using all images. The intra-class correlation coefficient (ICC) and the standard error of measurement (SEM) were calculatedResultsIntra-examiner reliability of image capture for the FHL muscle examined by USI was excellent for both thickness (ICC3,1, 0.944–0.976; SEM, 6.8%–10.0%) and CSA (ICC3,1, 0.954–0.979; SEM, 10.8%–16.5%), with no effect of examiner experience. Reliability was also excellent for measurement of thickness (ICC3,1, 0.954–0.972; SEM, 1.2%–9.6%) and CSA (ICC3,1, 0.961–0.986; SEM, 9.2%–14.1%), with no effects of experience.ConclusionsReliability of image capture and image-based measurements developed by USI of CSA and thickness for the FHL muscle in healthy individuals was excellent, independent of the examiner experience.

“…Ultrasound findings in elbow tendon pathology have been well reported with both structural [ 41 ] and blood flow changes described [ 42 ]. However, it´s not clear which findings have the greatest impact on clinical outcomes such as are symptoms and performance [ 43 , 44 ]. Current studies have proposed an association between neovascularity and pain and suggested that an adequate clinical outcome is related with improvement in neovascularity rather than structural changes [ 45 , 46 ].…”

Objective: The aim was to analyze effects of a percutaneous neuromodulation (PNM) treatment on the radial nerve, regarding pain, functionality, electrophysiologic excitability, and morphology, in patients with chronic lateral epicondylalgia (LE). Methods: Twenty-four patients with chronic unilateral elbow pain were recruited for this preliminary study and were divided into two groups: control (n = 12) and PNM group (n = 12). The subjects in the PNM group received percutaneous peripheral neurostimulation with an acupuncture needle that was located next to the nerve with ultrasound guidance. Pain using a numerical rating scale (NRS), functional ability using patient-rated tennis elbow evaluation (PRTEE), radial nerve cross-sectional area measured by ultrasound, and chronaxie and accommodation index (AI) measured by the strength–duration curve were evaluated. Results: Both groups showed no differences in the baseline measurements (all p = 0.001). However, at the end of the treatment, there were significant differences between groups since only the PNM group significantly improved their values compared to their baseline values: level of pain and cross-sectional area (CSA) values showed a significant decrease while the PRTEE scores showed a significant improvement. Then, regarding AI, the PNM group showed significant improvement for the electrophysiologic nerve excitability pattern, reporting normal function in all radial nerves after treatment (p = 0.001). However, chronaxie values always reported similar values with no differences between groups (p >0.05); Conclusion: Ultrasound-PNM technique may be an interesting therapeutic tool for the treatment of chronic LE due to the improvement in the level of pain, functionality, nerve morphology, and excitability in this population.
