“…Using ultrasound for the measurement of the abdominal muscles thickness is a valid and reliable method in adolescent populations (20,21). Also previous studies on healthy subjects have shown the correlation between the body weight and the ultrasound measurements of the lateral abdominal muscles (22,30,31).…”

“…Using ultrasound for the measurement of abdominal muscles thickness and thickness changes is a valid and reliable method in adolescent population (20,21). In the only ultrasound study assessing the thickness of lateral abdominal muscles in adolescents with AIS the thickness of all three muscles (External Oblique -EO, Internal Oblique -IO and Transverse Abdominis -TrA) on both sides at rest were smaller in the AIS group compared to the control group (13).…”

Background: It has been suggested that weakness and asymmetry of core stabilizing muscles have an important role in the development of scoliosis and its complications, especially low back pain. However there is insufficient data comparing symmetry and function of these muscles in scoliotic patients with the normal population. Also there are only a few studies assessing the relationship between the degree of spinal deviation and asymmetry of core stabilizing muscles. This study evaluates the thickness, symmetry, and activation of the external oblique (EO), the internal oblique (IO) and the transversus abdominis (TrA) muscles of patients with AIS and compares these data with a group of normal adolescents. Objectives: The objective of this observational study was to know the asymmetry pattern of lateral abdominal muscles at rest and during the abdominal drawing-in maneuver (ADiM) in adolescents with idiopathic scoliosis and to compare it with a group of healthy adolescents. Methods: Twenty healthy adolescents and twenty patients with AIS, aged 10 to 18 years, were included. The thickness of lateral abdominal muscles was measured, using ultrasound, at the end of normal exhalation at rest and during the abdominal drawing-in maneuver (ADiM). Muscular activity was represented as absolute difference and percentage change in the muscle thickness during the ADiM compared with rest. Results: There was no side to side asymmetry in muscle thickness at rest and also during ADiM in two groups. Thickness of right EO [0.39 (0.09) in the AIS group compared to 0.51 (0.12) in the normal group] and left EO [0.38(0.10) in the AIS group compared to 0.50 (0.11) in the normal group] at rest was higher in the normal group (P < 0.05). The activity of right and left EO was higher in AIS group (P < 0.05). There was a positive correlation between the lumbar Cobb's angle with the right and the right-to-left difference of TrA thickness during the ADiM (P < 0.05). In other words, the more the lumbar Cobb's angle to the right, the thicker the right TrA relative to the left TrA during the ADiM. Conclusions: The EO muscle was thinner and had higher activity during ADiM in the AIS group. Analysis of our data showed that in the AIS group the higher the lumbar spinal curve to the right, the thicker the right TrA compared to the left TrA.

“…All of them have been widely examined by ultrasound imaging, which is a relatively simple and cost-effective tool allowing reliable assessment of the muscles in different populations [12,15,28]. Some studies have tried to find some connection between OE, OI, and TrA morphology and conditions, such as low back pain and scoliosis [3,5,11,16,25].…”

“…Rehabilitative ultrasound imaging (RUSI), which allows the visualization of muscle contraction, has been shown to reliably assess the abdominal muscles in various body positions [11]. Measurement of abdominal muscle contraction thickness with RUSI during automatic response is a reliable technique in participants both with and without LBP [12].…”

Objective: Prone bridge exercise is one of the core strengthening exercise for improving abdominal, lower and upper extremity muscles. In addition, coactivation of the trunk muscles and extremities is important for treatment of low back pain. This study aimed to investigate the correlation between the thickness, cross-sectional area of the target muscle, and endurance during prone bridge exercise. Our hypothesis was that an increase in muscle thickness is positively related to the hold time for the static prone bridge exercise. Design: Cross-sectional study. Methods: Fourteen healthy university students (8 men and 6 women) voluntarily participated in the study at Sahmyook University. Hold time for the prone bridge with one and both legs was measured. The resting and contracted thickness of the lateral abdominal, rectus femoris, and triceps muscles was measured using rehabilitative ultrasound imaging. The correlation between muscle thickness and endurance for maintenance time was evaluated. Results: The prone bridge with both legs and the contraction thickness of the triceps muscle showed a positive correlation (r=0.692, p<0.05); the prone bridge with one leg and the contraction thickness of the internal oblique and transversus abdominis muscles showed a positive correlation (r=0. 545, 0.574, p<0.05, 0.05, respectively). Conclusions: Endurance for the prone bridge exercise with a stable support surface is correlated with the contraction thickness of arm muscles; the prone bridge exercise with an unstable support surface is correlated with the contraction thickness of the deep abdominal muscles.
