“…The measurements of the muscular architecture acquired in this investigation are in good agreement with measurements of the quadriceps muscle assessed in earlier studies using ultrasonography [ 4 ]. The mean CSA of VM for the group A was (15.26+2.33), group B was (15.98+2.55), group C was (16.09+2.8) and group D was (13.94+2.7) which is coinciding with Minnehan et al [ 13 ]. There was significant inverse correlation between CSA of VM and age and positive correlation with BMI.…”

Quadriceps weakness and morphological alteration is a documented phenomenon that can have a major impact on strength and functional performance of PFPS patients. An effective and trustworthy non-invasive technique for measuring the quadriceps muscle's anatomy and architecture is B- Mode Ultrasonography. The aim of the study is to assess & compare the effectiveness of neuromuscular electrical stimulation application, quadriceps strengthening & in combination on the quadriceps muscle architecture and functional capacity in patients with Patello femoral pain syndrome. One hundred and twenty-four participants aged 18 - 40 years old with anterior knee pain were included. Participants were randomly allocated into four groups. Group A participants were given NMES, group B were given QS, group C were given combination therapy (NMES+QS) and group D was control group. Cross sectional area, Fascicle length & pennation angle were measured using B-Mode (2D) ultrasound for Quadriceps Femoris muscle. Knee function & pain were assessed using Kujala score and VAS. All parameters were evaluated before and after the intervention. The mean age, weight, height & BMI of control, NMES, QS and NMES+QS were not statistically significant (P = 0.881, 0.960, 0.951 & 0.953) which shows that the control and experimental groups were homogenous. Combination group showed significant improvement when compared to QS group followed by NMES group. Control group did not show any improvement. Neuromuscular Electrical Stimulation in combination with quadriceps strengthening showed a better outcome than in isolation on quadriceps muscle architecture after 10 weeks.

“…To evaluate large muscle, the panoramic view of ultrasound can be used 22 – 25 . The panoramic view showed excellent inter-rater reliability and good correlation with MRI in measuring the cross-sectional areas of the quadriceps femoris (concordance correlation coefficient 0.78, p < 0.001) 22 , vastus medialis (interclass correlation coefficient about 0.98 and interrater reliability about 0.99) 23 , and hamstring muscles (correlation coefficient r ≥ 0.8) 24 . Thus, panoramic mode is a good tool for evaluating large muscles, such as the quadriceps femoris.…”

“…Sixth, this study did not aim to evaluate the variability in measurements. Although the previous studies reported that the panoramic view showed excellent inter-rater reliability and good correlation with MRI in measuring the cross-sectional areas of the quadriceps femoris 22 , vastus medialis 23 , and hamstring muscles 24 , further studies are needed to evaluate the variability in measurements in patients with sepsis.…”

Muscle mass depletion is associated with mortality and morbidity in various conditions including sepsis. However, few studies have evaluated muscle mass using point-of-care ultrasound in patients with sepsis. This study aimed to evaluate the association between thigh muscle mass, evaluated using point-of-care ultrasound with panoramic view in patients with sepsis in the emergency department, and mortality. From March 2021 to October 2022, this prospective observational study used sepsis registry. Adult patients who were diagnosed with sepsis at the emergency department and who underwent point-of-care ultrasounds for lower extremities were included. The thigh muscle mass was evaluated by the cross-sectional area of the quadriceps femoris (CSA-QF) on point-of-care ultrasound using panoramic view. The primary outcome was 28 day mortality. Multivariable Cox proportional hazard model was performed. Of 112 included patients with sepsis, mean CSA-QF was significantly lower in the non-surviving group than surviving group (49.6 [34.3–56.5] vs. 63.2 [46.9–79.6] cm2, p = 0.002). Each cm2 increase of mean CSA-QF was independently associated with decreased 28 day mortality (adjusted hazard ratio 0.961, 95% CI 0.928–0.995, p = 0.026) after adjustment for potential confounders. The result of other measurements of CSA-QF were similar. The muscle mass of the quadriceps femoris evaluated using point-of-care ultrasound with panoramic view was associated with mortality in patients with sepsis. It might be a promising tool for determining risk factors for mortality in sepsis patients in the early stages of emergency department.

“…To measure acute muscle swelling researchers have used Ultrasound (US) images to measure changes in muscle size via muscle thickness measures [1,2] and Cross-Sectional Area (CSA) [3]. These measurements have both been shown to be valid when compared to CT [4] and MRI [5] scans, and reliable [6] amongst different clinicians. Muscle thickness has been shown to increase following resistance training [7], concentric [2], eccentric [8] and isometric [9] contractions, however it is not conclusive as others have shown size not to increase following resistance training [10].…”

Following resistance training, muscles swell due to a combination of damage, an increased demand for oxygen, and buildup of substrates. Cross-Sectional Area (CSA), thickness, and Echo Intensity (EI) are measurements that have been used to monitor muscle damage and recovery. Due to the variety in responses to resistance training, the aim of this study was to examine the time course changes in muscle size and EI of the elbow flexors and knee extensors following an acute bout of resistance training and determine the potential differences in response between males and females. Twenty Males (71.00±2.07cm, 74.11±9.37kg, Age 19.85±0.41) and 20 females (63.35±2.99cm, 60.62±8.92kg, Age 20.00±0.72) had panoramic ultrasound images taken of the largest circumference of the Bicep Bracii (BB), Vastus Medialis Oblique (VMO) and Vastus Lateralis (VL) and were used to determine CSA, muscle thickness and EI. Participants performed four sets to failure at 70% on a bicep curl and leg extension machine with a 90 second rest between sets. Ultrasounds were done pre and post exercise, 24 and 48-hours post. Males and females had similar responses over time (P=0.17-0.96) for each variable. Post exercise values for CSA, thickness, and EI (P<0.001) where all large but returned to baseline values by 24hrs. Males had large muscle size (P<0.001), and lower EI values (P<0.001) of the knee extensors but not of the elbow flexors (P=0.769). This study demonstrated that immediately following resistance training, muscle size and EI were significantly larger for both males and females and returned to baseline in 24hrs. Males and females exhibited similar patterns; however, males had larger knee extensor and elbow flexors muscles and lower EI values of the knee extensors on average than females.
