Biomechanical Evaluation of Intercostal Muscles in Healthy Children and Adolescent Idiopathic Scoliosis: A Preliminary Study

Spine deformity during adolescent idiopathic scoliosis can induce a rib-cage deformity. This bone have direct consequences on the chest-wall muscles, including intercostal leading to respiratory impairments in individuals with severe cases. The aim of this study was determine whether shear-wave elastography be used measure intercostal-muscle speed (SWS) healthy children and those (AIS). Nineteen participants 16 AIS took part. SWS measurements were taken by three operators, twice each. Average 2.3 ± 0.4 m/s, inter-operator reproducibility 0.2 m/s. significantly higher apnea than normal breathing (p < 0.01) both groups. No significant difference observed between groups or breathing. Characterization muscles ultrasound is therefore feasible reliable for adolescents without scoliosis.
