Patients with pre-existing spinopelvic pathology were excluded. Standing, relaxed-seated, and lateral decubitus lateral radiographs were obtained. Radiographic variables measured included LL and lordosis change at each lumbar level (e.g. L1-L2). The change in LL when going from a standing to a lateral decubitus position (\u0394LL), the correlation between standing and sitting LL compared to lateral decubitus LL, and the correlation between \u0394LL and standing pelvic incidence (PI), pelvic tilt (PT), PI-LL mismatch, pelvic femoral angle (PFA), and sacral slope (SS) were calculated.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Subjects had an average age of 25.7\u2009\u00b1\u20092.3 years and body mass index of 24.1\u2009\u00b1\u20093.0\u00a0kg\/m<jats:sup>2<\/jats:sup>.
