Neuromechanics of idiopathic scoliosis shoulders compensates the angular momentum of the pelvis (i.e. when the shoulders rotate clockwise, the pelvis rotates counterclockwise; when the pelvis rotates clockwise, the shoulders rotate counterclockwise). As scoliosis perturbs the architecture of the shoulders, spine and pelvis, gait also differs between patients and non-scoliotic people. Independently of the Cobb angle, the affected vertebra and the age, idiopathic scoliotic people have a larger rachis flexion range of motion and a narrower hips extension range of motion than non-scoliotic people. The range of motion for rachis extension, hips flexion, left and right lateral flexions are similar to non-scoliotic people. After arthrodesis,
Neuromechanics of idiopathic scoliosis vertebral column can be deformed at the thoracic level, at the lumbar level or at both. In the lumbar region, scoliosis induces perturbations to standing balance. The thoracic region is the location that most impacts movement strategies. Scoliosis impedes on the movement of the ribs, places the respiratory muscles at a mechanical disadvantage and displaces the various organs of the thoracic cavity. In a scoliotic patient, the vertebral column experiences extension forces on the convex side and compression forces on the concave side. At the apical vertebra, average bone density for the concave cortical bone is higher than for the
