Impact of Spinal Curves on Asymmetric Posture in Idiopathic Scoliosis

Asymmetric postures are often observed in patients with adolescent idiopathic scoliosis (AIS) and are partially associated with instability in sitting and standing positions, as well as with imbalances in gait kinematic parameters in cases of moderate or severe scoliosis. Based on the currently available data, no correlation has been identified between habitual postures in daily life and the presence of scoliosis. However, the asymmetry of preferred postures in relation to the morphological characteristics of the curves, and how this might contribute to the progression of the clinical condition due to prolonged uneven load distribution, has not yet been analyzed. Understanding any preferential direction in postures habitually adopted by patients with idiopathic scoliosis could provide valuable insights for the conservative management of the condition. The aim of this study is to analyze the influence of the morphological characteristics of scoliotic curves (type and laterality) in patients with juvenile and adolescent idiopathic scoliosis on the choice of preferentially maintained asymmetric postures in daily life, using a descriptive questionnaire completed by family members and caregivers, compared to a group of non-scoliotic subjects. Evaluate the effect of curve magnitude, age, sex, and Risser grade on the choice of usual asymmetric postures. Estimate the impact of prolonged maintenance of habitual asymmetric postures on the clinical progression in patients with juvenile and adolescent idiopathic scoliosis
