“…The primary aim of seventeen articles was to determine the metrological properties of a measurement technique. Ten articles had a score above 70/100 [9,27,28,45–51], fifteen articles had a score between 60 and 70/100 [25,26,52–64] and five articles had a score below 60/100 [29,65–68]. Details of the scores of each article are provided in S2 Table.…”

“…Seventeen articles included only healthy subjects [26,27,45–50,52,53,57–60,62,64,67] and six included subjects with a muscular pathology of which five were on adults with: low back pain, total unilateral arthroplasty, anterior cruciate ligament reconstruction, chronic obstructive pulmonary disease or knee osteoarthritis [9,28,61,63,65]; the fifth article was on children with cerebral palsy [51]. Three articles evaluated cadavers [25,54,56].…”

“…Forty different muscles were examined: upper limb muscles were assessed in six articles [25,29,50,54,56,62] and lower limb muscles in twenty-four articles [9,26–28,45–49,51–53,55,57–61,63–68]. The rectus femoris muscle was the most frequently evaluated (n = 13 articles).…”

“…Eight articles evaluated the use of CSA segmentation or muscle thickness using a single slice and muscle length to estimate muscle volume (Range Q scores: 61–78; mean Q score: 67.4) [50–53,57,58,60]. For the measurements, either the slice with the greatest CSA [51–53,57,58,60], or slices taken at specific locations (for example at 50% of the bone length) [28,50,60] were used. To estimate muscle volumes, equations using muscle length, CSA and shape factors were used.…”

AimsThe aim of this study was to report the metrological qualities of techniques currently used to quantify skeletal muscle volume and 3D shape in healthy and pathological muscles.MethodsA systematic review was conducted (Prospero CRD42018082708). PubMed, Web of Science, Cochrane and Scopus databases were searched using relevant keywords and inclusion/exclusion criteria. The quality of the articles was evaluated using a customized scale.ResultsThirty articles were included, 6 of which included pathological muscles. Most evaluated lower limb muscles. Partially or completely automatic and manual techniques were assessed in 10 and 24 articles, respectively. Manual slice-by-slice segmentation reliability was good-to-excellent (n = 8 articles) and validity against dissection was moderate to good(n = 1). Manual slice-by-slice segmentation was used as a gold-standard method in the other articles. Reduction of the number of manually segmented slices (n = 6) provided good to excellent validity if a sufficient number of appropriate slices was chosen. Segmentation on one slice (n = 11) increased volume errors. The Deformation of a Parametric Specific Object (DPSO) method (n = 5) decreased the number of manually-segmented slices required for any chosen level of error. Other automatic techniques combined with different statistical shape or atlas/images-based methods (n = 4) had good validity. Some particularities were highlighted for specific muscles. Except for manual slice by slice segmentation, reliability has rarely been reported.ConclusionsThe results of this systematic review help the choice of appropriate segmentation techniques, according to the purpose of the measurement. In healthy populations, techniques that greatly simplified the process of manual segmentation yielded greater errors in volume and shape estimations. Reduction of the number of manually segmented slices was possible with appropriately chosen segmented slices or with DPSO. Other automatic techniques showed promise, but data were insufficient for their validation. More data on the metrological quality of techniques used in the cases of muscle pathology are required.

“…The partial volume of a 100 mm section of the knee extensors has been associated with knee extensor strength in patients with a history of anterior cruciate ligament reconstruction (Kuenze et al 2016) and using partial volumes to represent MV may be a viable option. Evidence is also available to suggest that analysing a reduced number of axial images can provide an estimate of MV with good agreement and minimal error compared to a rigorous criterion (Tracy et al 2003; Morse et al 2007; Cotofana et al 2010; Hogrel et al 2015; Vanmechelen et al 2018). However, the operating costs associated with MRI limit its use on a regular basis, and it is not possible to acquire images from some individuals, such as those with known or suspected metal objects in their body, due to the heating effect of being in the magnetic field (e.g., individuals with shrapnel, orthopaedic implants such as pins or plates, or pacemakers).…”

A clinically applicable tool for rapidly estimating muscle volume using ultrasound images

PurposeThis study aimed to identify a safe, rapid, and accessible method of estimating muscle volume of key lower limb muscle groups to reduce the time-demand of acquiring this measurement and potentially facilitate its application as a clinical monitoring tool.MethodsUnilateral MRI images were acquired from the 12th thoracic vertebrae to the base of the foot in 18 recreationally active males. Panoramic B-mode ultrasound images were acquired from the same leg at the mid-hip, 25%, 50%, and 75% of thigh length, and 25% of shank length. Body mass, height, limb lengths, and circumferences at the sites corresponding to the ultrasound images were acquired. A single investigator manually analysed all images. Regression analyses were conducted to identify models for estimating volume of the hip extensor, knee extensor and flexor, and ankle plantarflexor muscle groups.ResultsModels were developed for estimating hip extensor (SEE = 8.92%, R2 = 0.690), knee extensor (SEE = 5.24%, R2 = 0.707) and flexor (SEE = 7.89%, R2 = 0.357), and ankle plantarflexor (SEE = 10.78%, R2 = 0.387) muscle group volumes. The hip and knee extensor models showed good potential for generalisation. Systematic error was observed for the knee flexor and ankle plantarflexor models.ConclusionsHip extensor, knee extensor and flexor, and ankle plantarflexor muscle group volumes can be estimated using B-mode ultrasound images and anthropometric measurements. The error shown for each of the models was sufficient to identify previously reported differences in muscle volume due to training or injury, supporting their clinical application.

Muscle volume (MV) is an important parameter for understanding muscle morphology and adaptations to training, growth and pathology. In this study, we assessed the validity of freehand 3D ultrasound (3DUS) for measuring medial gastrocnemius MV in adults, typically developing (TD) children and children with cerebral palsy (CP). We also assessed the validity between our direct measures of MV and estimates derived from anatomical cross sectional area (ACSA) and muscle length (ML), using previously outlined methods. The medial gastrocnemius of all groups was scanned with 3DUS and MRI. Images from both methods were digitized to derive MV, ACSA and ML. Measured MV was compared between methods and compared to estimated MV derived from recently published algorithms. MV had a mean difference of −0.13% (standard error of estimate (SEE) = 2.23%, R 2 = 0.99) between MRI and 3DUS and 19.82% (SEE = 4.73% and R 2 = 0.99) and −3.11% (SEE = 6.55%, R 2 = 0.99) mean differences between the measured and estimated MV from two methods of estimation. The 3DUS is a valid method for the measurement of MV in adults, TD children and those with CP. Estimation methods of MV may be useful in clinical practice, but require further replication on various populations and careful methodological consideration.
