Published: 19 January 2015
There are many evaluation tools of spinal deformities such as sagittal vertical axis (SVA), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS) and so on. But no reliable parameters have been defined for measurements of spinal alignment during gait analysis.
The purpose of this study is to assess the validity of our EGA-DARTFISH kinetic analysis parameter against established x-ray parameters and to evaluate its viability as an alternative to SVA.
Material and method
Gait analysis using EGA-DARTFISH provided good visibility and reproducibility for measuring spinal sagittal alignment. In adult spinal deformity, the anteversion angle while walking is 6 degrees. EGA DARTFISH may be an appropriate alternative to SVA for measuring sagittal alignment.
