Effects of 3D Postural Correction and Abdominal Muscle Contraction on the Symmetry of the Transverse Abdominis and Spinal Alignment in Patients with Idiopathic Scoliosis

Abstract

This study aimed to investigate the effectiveness of 3D postural correction (3DPC) using corrective cushions (CCs) and abdominal muscle contraction (AMC) on the thickness symmetry of the transversus abdominis (TrA) and spinal alignment in patients with idiopathic scoliosis (IS). In the first experiment, ultrasound measurements were taken of the TrA thickness on both the convex and concave sides of the lumbar curve in the supine position during AMC and non-AMC without 3DPC, and during AMC and non-AMC with 3DPC using CCs, in 11 IS patients. In the second experiment, 37 IS patients participated in a four-week 3DPC exercise program that aimed to maintain TrA thickness symmetry based on the results of the first experiment. The study found that TrA thickness symmetry significantly increased after 3DPC using CCs and combined with AMC (p < 0.05). Additionally, the Cobb angles and trunk rotation angles showed significant decreases, and trunk expansion showed a significant increase (p < 0.05). These results indicate that the simultaneous application of 3DPC and AMC is the most effective way to achieve TrA thickness symmetry in IS patients. Therefore, 3DPC and AMC should be considered as crucial elements in exercise interventions for IS patients.

Health technology assessment in musculoskeletal radiology: the case study of EOSedge™

“…As an example, young scoliotic female patients may undergo several examinations using X-rays, leading to an increased risk of developing breast cancer [ 16 ]. Also, evolutive pathologies such as cerebral palsy or early onset scoliosis also require biplanar X-ray spine exams for evaluation and follow-up due to the high risk of respiratory impairment [ 17 , 18 ], thus increasing cancer risk and potentially mortality [ 13 ].…”

Ativação neuromuscular do reto abdominal nos exercícios hundred, plank e crunch: Comparação eletromiográfica de superfície

“…Em relação aos exercícios isométricos hundred e plank, ambos realizaram maior ativação das unidades motoras do ventre muscular esquerdo quando comparado ao ventre muscular direito do MRA. Vale ressaltar que a simetria de ativação das unidades motoras entre os ventres dos músculos abdominais é importante para fornecer uma adequada estabilidade a coluna vertebral e para prevenir desequilíbrio biomecânicos secundários [30]. Evidências demonstraram que indivíduos que praticam esportes assimétricos podem apresentar diferenças no tamanho e recrutamento das fibras do ventre do MRA do hemicorpo esquerdo e direito [31,32], outro estudo já expõe a assimetria da musculatura abdominal em decorrência de alterações de alinhamento da coluna vertebral, como observada na escoliose idiopática em indivíduos adolescentes [30].…”
