“…For the last few decades, B-mode ultrasound imaging (USI) has been used to assess muscles' geometry. In some cases, USI has been used to assess lateral abdominal muscles (LAMs) thickness or thickness change at rest and during various movements because the potential role of LAM in low back pain (LBP) [1][2][3] and scoliosis [4][5][6][7][8][9][10][11] was verified. Recently, quantitative shear wave ultrasound elastography (SWE) has also been developed and used to study muscle shear modulus [12] and refer it to muscles' elasticity.…”

The aim of this study was to perform a reliability and agreement analysis and to compare lateral abdominal muscles (LAMs) thickness and elasticity results obtained by an experienced operator, by a non-experienced operator, and in an ultrasound imaging probe compression controlled (PCC) condition with minimal force necessary to obtain a proper ultrasound image. The sample consisted of 39 adolescents. An Aixplorer ultrasound scanner was used to evaluate the LAM. The probe in PCC condition was positioned in a prepared probe holder coupled with a pressure sensor. The LAM thickness and elasticity measurements were significantly (p < 0.05) different in the ultrasound PCC condition, compared to results obtained by both examiners. The abdominal oblique external and internal muscle thickness measurements were underestimated and all LAM shear moduli were overestimated during measurements without controlling the probe compression by an external sensor. The intra-class correlation coefficient was excellent in all conditions, but the smallest detectable differences were approximately 43–60% lower during the measurements collected in PCC condition. Differences in LAM measurements between PCC and ‘on-hand’ conditions may be clinically irrelevant when the force applied by the probe is consciously controlled by the examiner. However, during ultrasound measurements of the LAM morphology, the potential under/over estimation should always be considered when measurements are performed without controlling probe compression by an external sensor.

“…Similarly, Kim et al 5 have shown no differences in LAM thickness between IS and control group, and Yang et al 4 have observed thicker OE muscle on the convex body side compare to concave side in IS. In contract, some studies have shown no side-to-side asymmetry of all LAM in IS patients 6,26 . In general, there are no consistent observations on LAM side-to-side asymmetry in studies on healthy adolescents [27][28][29] , and it is suggested that the symmetry of LAM depends on the biomechanics during sport's practice in athletes 28,29 .…”

“…In turn, elasticity analysis within the scoliosis group showed: (a) no significant asymmetry in LAM elasticity between convex and concave body sides; (b) the TrA during isometric contraction was stiffer in the lumbar subgroup compared to thoracic and thoracolumbar subgroups. www.nature.com/scientificreports/ www.nature.com/scientificreports/ In the literature, there are some studies comparing LAM thickness in IS with non-IS controls and/or considering LAM thickness side-to-side asymmetry (convex vs. concave) only in IS group [4][5][6][7]12,26 . The results of the presented study demonstrated that LAM thickness at rest was similar in IS and non-IS groups, but side-to-side asymmetry of the OE muscle at rest and during isometric contraction was only detected in IS group (left side thicker).…”

Considering that knowledge about lateral abdominal muscles (LAM) in idiopathic scoliosis (IS) is still very limited, the aims of this study were: (a) to compare LAM thickness and elasticity between C-shaped IS and non-scoliotic population; and (b) to compare LAM thickness and elasticity between C-shaped thoracic, thoracolumbar, and lumbar IS. A total of 259 adolescents were included in the final analysis; among these, 108 were IS and 151 were non-IS. LAM thickness and elasticity were measured at rest and during isometric contraction by an Aixplorer ultrasound scanner. Out of all LAM, only OE thickness was higher on the convex body side compared to the concave side in lumbar and thoracolumbar scoliosis. It may be related with muscle’s atrophy/hypertrophy or other tissues displacement rather than different force generated by the muscle on both body sides, because an asymmetry in the elasticity of the LAM between the convex and concave side was not presented. The only TrA was stiffer in lumbar scoliosis compared to thoracolumbar and thoracic scoliosis. LAM elasticity was similar in IS and non-IS adolescents.

Assessment of Body Posture of Children With Chest Pain

et al. 2021

Objective: An increase in the appearance of chest pain among children is observed globally. The authors present various reasons for their appearance. As can be seen from numerous observations, the majority of cases are not related to the pathology of the circulatory system. Increasingly, studies on the causes of chest pain in children show their association with musculoskeletal disorders.Aim: of the work was assessment of body posture in children with chest pain using the Diers Formetric 4D system.Methods: The study involved a group of 184 female and male children, aged 7–12 years. The study group consisted of 64 patients with chest pain. The children from this group were diagnosed with functional chest pain by a cardiologist. The control group consisted of 120 patients without chest pain. The study included the assessment of body posture using the DIERS Formetric system.Results: The analysis of the results obtained during the study showed that among the children with chest pain, there are statistically significant irregularities in the parameters determining body posture compared to the control group.Comparing the study group with the control group, there is a statistically significant difference in the lateral deviation of VPDM (rms) (mm) (p = 0.001). Both children from the test group aged 9–10 and 11–12 obtained higher results than their peers from the control group. In the group of the youngest children in terms of the lateral deviation of VPDM (rms) (mm), increasing the number of children under study would contribute to significant differences in this variable.In the study group, among children aged 9–10 years, there were also statistically significant abnormalities regarding trunk imbalance and pelvic skewness compared to the children of the same age in the control group.Conclusions: Irregularities in the parameters determining body posture may cause chest pain in children.
