“…Our participants took approximately 7500 to 8000 steps per day on non-walking days, and the score of physical functional performance was better than that in our previous reports [ 19 , 29 ]. These characteristics would imply that participants were very active and did not have obstacle to the exercise and made it possible to achieve our home-based training protocol because participants were required to manage and fulfill their own training quota considering their lifestyle.…”

“…Subcutaneous fat thickness, muscle thickness, and EI of the mid-thigh were measured by ultrasonography, as in our previous study [ 19 , 28 , 29 ]. Ultrasonography was performed after 15 min rest in order to avoid the influence by the body fluid shifts induced by muscle contraction [ 30 ].…”

“…Wilhelm et al [ 17 ] showed that concurrent strength and endurance training increased muscle thickness and decreased ultrasound echo intensity (EI), which reflects IMF and/or connective tissue content. Higher skeletal muscle EI is associated with lower muscle quality [ 18 , 19 ]. Previous studies have shown that a statistically significant correlation exists between muscle EI and adipose tissue level in a muscle biopsy sample [ 20 ].…”

BackgroundOlder individuals have been shown to present muscle atrophy in conjunction with increased fat fraction in some muscles. The proportion of fat and connective tissue within the skeletal muscle can be estimated from axial B-mode ultrasound images using echo intensity (EI). EI was used to calculate the index of muscle quality. Walking, home-based weight-bearing resistance training, and its combinations are considered simple, easy, and practical exercise interventions for older adults. The purpose of this study was to quantify the effects of walking and walking with home-based resistance training on muscle quality of older individuals.MethodsThirty-one participants performed walking training only (W-group; 72 ± 5 years) and 33 participants performed walking and home-based resistance training (WR-group; 73 ± 6 years). This study was a non-randomized controlled trial with no control group. All participants were instructed to walk 2 or 3 sets per week for 10 weeks (one set: 30-min continuous walking). In addition, the WR-group performed home-based weight-bearing resistance training. EI was measured as a muscle quality index using axial B-mode ultrasound images of the rectus femoris and vastus lateralis of the mid-thigh. We further averaged these parameters to obtain the EI of the quadriceps femoris (QF). Participants further performed five functional tests: sit-ups, supine up, sit-to-stand, 5-m maximal walk, and 6-min walk.ResultsQF EI was significantly decreased in both groups after training (W-group 69.9 ± 7.4 a.u. to 61.7 ± 7.0 a.u., WR-group 64.0 ± 9.5 a.u. to 51.1 ± 10.0 a.u.; P < 0.05), suggesting improved muscle quality. QF EI was further decreased in the WR-group compared with the W-group. The sit-up test in both groups and the sit-to-stand and 5-m maximal walk tests in the W-group were significantly improved after training.ConclusionThese results suggest that training-induced stimulation is associated with a decrease in EI in some thigh regions. Furthermore, the addition of home-based resistance training to walking would be effective for a greater reduction of EI.

“…However, its shortcomings are the high cost and radiation exposure. Ultrasound [17][18][19][20][21][22][23][24][25][26][27] is feasible for a safe routine test and is cost effective. However, the diagnosis is operator dependent, and there have been limited experiences of ultrasound image analysis for sarcopenia.…”

“…In the aforementioned ultrasound sarcopenia diagnosis studies [17][18][19][20][21][22][23][24][25][26][27][28], no sarcopenia-specific automatic device(system) was developed to accurately quantify muscle mass thickness and strength. Moreover, robotic(automatic) ultrasound systems [29][30][31][32][33][34][35][36][37][38][39][40][41] have not been developed for sarcopenia diagnosis.…”

Sarcopenia is defined as muscle mass and strength loss with aging. As places, such as South Korea, Japan, and Europe have entered an aged society, sarcopenia is attracting global attention with elderly health. However, only few developed devices can quantify sarcopenia diagnosis modalities. Thus, the authors developed a sarcopenia detection system with 4 degrees of freedom to scan the human thigh with ultrasound probe and determine whether he/she has sarcopenia by inspecting the length of muscle thickness in the thigh by ultrasound image. To accurately measure the muscle thickness, the ultrasound probe attached to the sarcopenia detection system, must be moved angularly along the convex surface of the thigh with predefined pressure maintained. Therefore, the authors proposed an angular thigh scanning method for the aforementioned reason. The method first curve-fits the angular surface of the subject’s thigh with piecewise arcs using D information from a fixed RGB-D camera. Then, it incorporates a Jacobian-based ultrasound probe moving method to move the ultrasound probe along the curve-fitted arc and maintains radial interface force between the probe and the surface by force feedback control. The proposed method was validated by in-vitro test with a human thigh mimicked ham-gelatin phantom. The result showed the ham tissue thickness was maintained within approximately 26.01 ± 1.0 mm during 82° scanning with a 2.5 N radial force setting and the radial force between probe and surface of the phantom was maintained within 2.50 ± 0.1 N.
