“…These considerations support the use of curved-array transducers for longitudinal studies of rectus dimensions. Our findings also underscore the ease with which operators can be trained [25] and that curved-array transducers require no greater expertise than that employed in the use of linear-array transducers.…”

Abstract-Muscle-mass loss augers increased morbidity and mortality in critically ill patients. Muscle-mass loss can be assessed by wide linear-array ultrasound transducers connected to cumbersome, expensive console units. Whether cheaper, handcarried units equipped with curved-array transducers can be used as alternatives is unknown. Accordingly, our primary aim was to investigate in 15 nondisabled subjects the validity of measurements of rectus femoris cross-sectional area by using a curvedarray transducer against a linear-array transducer-the referencestandard technique. In these subjects, we also determined the reliability of measurements obtained by a novice operator versus measurements obtained by an experienced operator. Lastly, the relationship between quadriceps strength and rectus area recorded by two experienced operators with a curved-array transducer was assessed in 17 patients with chronic obstructive pulmonary disease (COPD). In nondisabled subjects, the rectus cross-sectional area measured with the curved-array transducer by the novice and experienced operators was valid (intraclass correlation coefficient [ICC]: 0.98, typical percentage error [%TE]: 3.7%) and reliable (ICC: 0.79, %TE: 9.7%). In the subjects with COPD, both reliability (ICC: 0.99) and repeatability (%TE: 7.6% and 9.8%) were high. Rectus area was related to quadriceps strength in COPD for both experienced operators (coefficient of determination: 0.67 and 0.70). In conclusion, measurements of rectus femoris crosssectional area recorded with a curved-array transducer connected to a hand-carried unit are valid, reliable, and reproducible, leading us to contend that this technique is suitable for cross-sectional and longitudinal studies.

“…Ultrasound provides a safe and more widely available technique to accurately quantify and qualify regional muscle mass. Data from cadaver [140] and MRI studies [141] reveal that ultrasound is a valid and reliable tool to assess muscle CSA, thickness, and volume. Interestingly, we recently found that local muscle hypertrophy may be detected on ultrasound before changes in DXA are apparent [122].…”

Muscle Quality in Aging: a Multi-Dimensional Approach to Muscle Functioning with Applications for Treatment

Aging is often accompanied by declines in physical functioning which impedes older adults' quality of life, sense of independence, and ability to perform daily tasks. Age-related decreases in skeletal muscle quantity, termed sarcopenia, have traditionally been blamed for these physical decrements. However, recent evidence suggests that the quality of muscle tissue may be more functionally relevant than its quantity. 'Muscle quality' has been emerging as a means to elucidate and describe the intricate intramuscular changes associated with muscle performance in the context of aging and sarcopenia. While muscle quality has most commonly been defined in terms of muscle composition or relative strength, at the core, muscle quality really describes muscle's ability to function. Skeletal muscle displays a strong structure-function relationship by which several architectural characteristics factor into its functional capacity. This review describes the structural, physiological, and functional determinants of muscle quality at the tissue and cellular level, while also introducing other novel parameters such as sarcomere spacing and integrity, circulating biomarkers, and the muscle quality index. Muscle qualitative features are described from the perspective of how physical exercise may improve muscle quality in older adults. This broad, multidimensional perspective of muscle quality in the context of aging and sarcopenia offers comprehensive insights for consideration and integration in developing improved prognostic tools for research and clinical care, while also promoting translational approaches to the design of novel targeted intervention strategies designed to maintain function and mobility into late life.

“…Previous studies (Ahtiainen et al 2010;Korhonen et al 2009;Radaelli et al 2012Radaelli et al , 2013Rosenberg et al 2014;Scott et al 2012) have examined the reliability of ultrasound (US) imaging for the assessment of skeletal muscle size. For example, muscle thickness (MT), defined as the distance from the adipose-muscle interface to the muscle-bone interface in a single transverse US image, has been reported to be a reliable measurement of muscle size (Radaelli et al 2013).…”

“…However, a single transverse image does not allow for the calculation of muscle cross-sectional area (mCSA) in large muscles. Recent advancements in US technology include panoramic scanning software that constructs a 2-D cross-sectional image of muscles (Ahtiainen et al 2010;Scott et al 2012), which allows for the calculation of mCSA (Melvin et al 2014;Rosenberg et al 2014). Noorkoiv et al (2010) suggested that the reliability of panoramic US images is influenced by the degree of curvature of the region or muscle of interest.…”
