BACKGROUND Early identification of patients at high risk of prolonged mechanical ventilation is important in critical care. Sarcopenia, the loss of muscle mass and function, has been reported to be associated with extended mechanical ventilation and prolonged ICU stay. Although ultrasound is noninvasive and widely used in critical care, there is no standard method of using it to assess sarcopenia. OBJECTIVES The study aims to investigate the relationship between outcomes of critically ill patients and the ratio of BMI to the thickness of rectus abdominis measured by a standardised ultrasound examination. DESIGN A retrospective cohort study. SETTING Surgical ICU of a tertiary referral hospital, from October 2017 to June 2018. The thickness of rectus abdominis (RA) was measured while performing extended focused assessment sonography for trauma. BMI was divided by the thickness of rectus abdominis over the upper abdomen to derive the BMI-RA thickness ratio. PATIENTS Sixteen male and 11 female patients admitted to ICU after major abdominal surgery. MAIN OUTCOME MEASURES The primary outcome was in-hospital mortality, and the secondary outcomes were durations of mechanical ventilation, ICU stay and hospital stay. The disease severity, serum albumin level and BMI-RA thickness ratio were also analysed. RESULTS Ultrasound measurement was easy to perform without adverse effects. The BMI-RA thickness ratio was significantly higher in nonsurvivors and was associated with ICU stay, hospital stay and duration of mechanical ventilation. Multivariable logistic regression showed that the BMI-RA thickness ratio was a predictor of in-hospital mortality. CONCLUSION The BMI-RA thickness ratio is related to the outcomes of patients transferred to ICU after major abdominal surgery. Measuring the thickness of rectus abdominis by ultrasound is well tolerated and easy to perform in surgical ICU. Larger prospective studies are required to confirm current findings.

“…However, it was observed that subjects with GJH had lower values in maneuvers requiring forced expiration such as FEV1 and MEP. This suggests that the abdominal muscles, which play an important role in forced expiration, may also be affected due to deterioration in the connective tissue (37,38). Studies in the literature on functional muscle strength in joint hypermobility generally focus on the lower extremity muscles, but more research is required to investigate trunk muscles including abdominals.…”

Aim: Genetic involvement of connective tissue containing elastin, collagen, and fibrils in joint hypermobility determines the tightness and laxity of the ligaments, thereby increasing the possibility of injuries by affecting the stability of joint capsules and the extensibility of tendons. The aim of this study was to investigate the effects of generalized joint hypermobility (GJH) on respiratory function, respiratory muscle strength, chest expansion, and functional capacity in healthy young adults. Material and Method: Thirty subjects aged between 18-25 years with a four or higher Beighton Score were included as the GJH group, and 30 healthy age-gender volunteers with three or lower scores were included as the control group. Functional capacity was measured with the 6-Minute Walk Test (6MWT), the quadriceps muscle strength with a digital dynamometer, pulmonary function and respiratory muscle strength with a spirometry, and chest expansion with a tapeline. Results: There were significant differences in the 6MWT distance (p=0.017), FVC (p=0.001), FEV1 (p=0.001), and MEP (p0.05). There is a significant difference in the xiphoid (p

“…The remarkable finding was that as the inward pressure increased, the ICC values of muscle thickness improved. To obtain a stable position, orientation, and consistent inward pressure of the transducer, delicate attention is required during rehabilitative ultrasound imaging [24]. When specific inward pressure is applied, vibration and the gap between the gel and skin might be minimized.…”

Objective: This reliability study examined the effects of applying varying induced inward pressures using a transducer placed at 0° neutral ankle position (NEU) and 15° ankle dorsiflexion (DF) on tibialis anterior (TA) muscle thickness using a custom-made device with a force indicator during rehabilitative ultrasound imaging. Design: Cross-sectional study. Methods: Twenty-four healthy subjects were recruited in this study. Two examiners measured the muscle thickness of the TA at 0° NEU and 15° DF in 3 conditions of inward pressures (1.0 N, 2.0 N, and 4.0 N) using a custom-made holder. The muscle thickness was measured three times for each of the conditions arranged in random order. For intra-and inter-rater reliability, the intraclass correlation coefficients (ICCs) with 95% confidence intervals, standard error of measurement, minimal detectable change, and coefficient of variation were analyzed. One-way repeated measures analysis of variance was conducted for investigating changes of TA muscle thickness according to the inward pressures of the transducers. Results: The intra-rater reliability of TA muscle thickness measurement was excellent (ICC3,1: 0.92-0.96) for all conditions (at both ankle joint angles per varying inward pressure). Likewise, the inter-rater reliability of TA muscle thickness measurement was excellent (ICC2,1: 0.89-0.97) under same conditions. The mean of TA thickness showed the trend of decreasing significantly with increased inward pressures at all ankle joint angles (p<0.05). Conclusions: Use of this custom-made device with a force indicator is useful to accomplish the high intra-and inter-rater reliability of TA muscle thickness measurement at both ankle joint angles in reducing the measurement error.

Correlation Between Abdominal Muscle Thickness and Maximal Expiratory Pressure

Abstract: Our results indicate that the rectus abdominis muscle thickness might be more highly correlated with expiratory pressure production than the external oblique, internal oblique, and transverse abdominis muscle thickness.
