The intervertebral efforts, i.e., forces and torques, during gait have been recognized as influencing the progression of scoliosis, due to the mechanical modulations according to the Hueter-Volkmann Law. Therefore, these efforts are key variables for posture correction and to control the progression of scoliosis. Using the intervertebral efforts during gait for the clinical follow-ups has never been performed. For this, it would be necessary to identify amongst all these efforts the most relevant ones, which is the objective of this study. A previously developed dynamical model of the human body was used to compute the 3 D intervertebral efforts during the gait of 15 participants with adolescent idiopathic scoliosis (AIS) and 12 typically developed adolescents (TDA). Kolmogorov-Smirnov and Two-sample t-test were applied on the calculated intervertebral efforts and the graphs of intervertebral efforts were studied. Antero-posterior (AP) forces and torques and medio-lateral (ML) forces are the most relevant intervertebral efforts amongst the other efforts in adolescents with AIS during gait. Discussion: Gait analysis in adolescents with AIS based on the relevant intervertebral efforts could be an effective means to follow-up and evaluate the progression of scoliosis during their treatment period. This study highlights the most relevant intervertebral efforts of individuals with AIS during gait. As future work, the identified intervertebral efforts could be implemented in a quantified and visual feedback tool for therapeutic and performance evaluation or interactive sessions in physiotherapy, e.g., via video games for dynamic posture self-correction.

由于根据Hueter-Volkmann定律的机械调节，步态期间的椎间作用力（即力和扭矩）已影响脊柱侧弯的发展。因此，这些努力是姿势矫正和控制脊柱侧弯进展的关键变量。从未在步态期间使用椎间努力进行临床随访。为此，有必要在所有这些努力中找出最相关的努力，这是本研究的目的。在15名青少年特发性脊柱侧凸（AIS）和12名典型发育中的青少年（TDA）的步态中，使用先前开发的人体动力学模型来计算3D椎间活动。将Kolmogorov-Smirnov和两次样本t检验应用于计算出的椎间作用力，并研究椎间作用力图。在步态活跃的AIS青少年中，除其他作用外，前后后（AP）力和扭矩以及中外侧（ML）力是最相关的椎间作用。讨论：基于相关的椎间努力，对青少年AIS进行步态分析可能是随访和评估治疗期间脊柱侧弯进展的有效方法。这项研究突出了步态期间AIS患者最相关的椎间努力。作为未来的工作，可以在量化和视觉反馈工具中实施已识别的椎间努力，以进行治疗和性能评估或物理治疗中的互动环节，例如，
