Variation of the sagittal vertical axis during walking and its determinants
TypeArticles dans des revues avec comité de lecture
Patients with adult spinal deformities (ASD) are known to have altered postural alignment aﬀecting their quality of life and activities of daily living, especially gait. The Sagittal Vertical Axis (SVA), a postural parameter calculated as the distance between the posterior corner of the sacrum and the C7-plumbline on full-body sagittal radiographs , has been shown to be highly altered in ASD. Even though this parameter is positional and could vary during gait, no studies have investigated its variation during walking even in asymptomatic subjects.
