“…Overall, the results of the present study suggest that reliable measures of MG architecture at rest can be attained using a combination of ultrasonography and image analysis. Although a recent study [ 16 ] found inter-rater reliability of MG architecture to be good-excellent (ICC = 0.77-0.90), it is recommended that a single rater both captures and analyzes MG ultrasound images due to the higher ICCs reported in the present study. Also, where possible, it is recommended that sonographic images of pennate skeletal muscle is recorded using a probe of sufficient proportions to allow for the capture of the entire fascicle length, given the previously reported underestimation [ 14 ] and greater within-image [ 11 ] and between-session [ 12 ] variability reported when using the linear extrapolation method.…”

Within- and between-session reliability of medial gastrocnemius architectural properties

This study aimed to determine the within- and between-session reliability of medial gastrocnemius (MG) architecture (e.g. muscle thickness (MT), fascicle length (FL) and pennation angle (PA)), as derived via ultrasonography followed by manual digitization. A single rater recorded three ultrasound images of the relaxed MG muscle belly for both legs of 16 resistance trained males, who were positioned in a pronated position with their knees fully extended and the ankles in a neutral (e.g. 90°) position. A subset of participants (n = 11) were retested under the same conditions ~48-72 hours after baseline testing. The same rater manually digitized each ultrasound image on three occasions to determine MG MT, FL and PA before pooling the data accordingly to allow for within-image (n = 96), between-image (n = 32) and between-session reliability (n = 22) to be determined. Intraclass correlation coefficients (ICCs) demonstrated excellent within-image (ICCs = 0.99-1.00, P < 0.001) and very good between-image (ICCs = 0.83-0.95, P < 0.001) and between-session (ICCs = 0.89-0.95, P < 0.001) reliability for MT, FL and PA. Between-session coefficient of variation was low (≤ 3.6%) for each architectural parameter and smallest detectible difference values of 10.6%, 11.4% and 9.8% were attained for MT, FL and PA, respectively. Manually digitizing ultrasound images of the MG muscle at rest yields highly reliable measurements of its architectural properties. Furthermore, changes in MG MT, FL and PA of ≥ 10.6%, 11.4% and 9.8% respectively, as brought about by any form of intervention, should be considered meaningful.

“…Three images were taken at each site in a longitudinal plane, and then exported to Image J (National Institutes of health, Bethesda, MD, United States, version 1.8.0_112) for analysis. The average value from the three images were used for analysis (Aagaard et al, 2001); a methodology that has shown high absolute and relative reliability for architectural parameters being measured in this way (Ema et al, 2013b;König et al, 2014;Silva et al, 2018). All images were taken from the participants' dominant limb (defined as the leg with which they would kick a ball) by the same experienced sonographer.…”

“…Reported estimates of reliability were good to high. [13][14][15][16][17][18][19][20][21] With the exception of a study reported by Thoirs and Englsh, 15 the reported intrarater correlation coefficients (ICC) among studies ranged between 0.90 and 0.99. Thoirs and Englsh 15 reported that high test-retest reliability was indicated in the lower extremity when subjects were measured in a standing position (ICC, 0.70-0.89; 95% confidence interval (CI), 0.79-0.94 for anterior thigh and 0.49-0.84 for posterior thigh, respectively).…”

“…Two studies 16,21 reported interrater reliability in the lower extremity muscles and the values demonstrated high reliability (ICC, 0.82 and 0.95). Furthermore, a study 19 investigated inter-machine reliability of different ultrasound machines and found that inter-machine reliability was considered excellent.…”

Morphological and functional relationships with ultrasound measured muscle thickness of the lower extremity: a brief review

2015

View full text Add to dashboard Cite

Ultrasound is a potential method for assessing muscle size of the extremity and trunk. In a large muscle, however, a single image from portable ultrasound measures only muscle thickness (MT), not anatomical muscle cross-sectional area (CSA) or muscle volume (MV). Thus, it is important to know whether MT is related to anatomical CSA and MV in an individual muscle of the extremity and trunk. In this review, we summarize previously published articles in the lower extremity demonstrating the relationships between ultrasound MT and muscle CSA or MV as measured by magnetic resonance imaging and computed tomography scans. The relationship between MT and isometric and isokinetic joint performance is also reviewed. A linear relationship is observed between MT and muscle CSA or MV in the quadriceps, adductor, tibialis anterior, and triceps surae muscles. Intrarater correlation coefficients range from 0.90 to 0.99, except for one study. It would appear that anterior upper-thigh MT, mid-thigh MT and posterior thigh MT are the best predictors for evaluating adductor, quadriceps, and hamstrings muscle size, respectively. Despite a limited number of studies, anterior as well as posterior lower leg MT appear to reflect muscle CSA and MV of the lower leg muscles. Based on previous studies, ultrasound measured anterior thigh MT may be a valuable predictor of knee extension strength. Nevertheless, more studies are needed to clarify the relationship between lower extremity function and MT.

Inter‐Rater Reliability and Measurement Error of Sonographic Muscle Architecture Assessments

Abstract: Sonographic examination of muscle architecture of the medial gastrocnemius has good to high reliability. In contrast to pennation angle measurements, length measurements can be improved by standardization of the probe position.
