A new quasi-invariant parameter characterizing the postural alignment of young asymptomatic adults

Abstract: This study on 3D postural alignment reports the geometry of the spine, pelvis and lower limbs, of the young asymptomatic adult. The less variable angle is the one of the line OD-HA with the vertical, highlighting the vertical alignment of the head above the pelvis. This study provides a basis for future comparisons when investigating aging populations.

“…There exists a high degree of agreement between our research and the literature on X-ray-based normal sagittal spine morphology (a short review is found in S1 Table [7174,87,89,91,94,96,100103]) regarding the mean angle values obtained in our population by measuring the profile of spinous processes in a neutral standing upright posture with arms at the side. Due to changes in spinal profile induced by ageing [5] the data reported in S1 Table refer to populations with an age range similar to that analysed in the present study.…”

“…Normative data from X-Ray measurements for Thoracic Kyphosis span a range of 20°-70° thus presenting a high variability among the studies [51,7174,86,87,89,91,9497]. In one of the earliest studies on sagittal alignment, Stagnara et al [95] concluded that the “span of possible values of maximum kyphosis and lordosis in subjects with no spinal disease is considerable.…”

“…We hypothesized that it may be the result of a pathological interaction between postural and ventilatory functions. Twelve patients with OSAS (4 women, age 53 years [51][52][53][54][55][56][57][58][59][60][61][62][63] (median [quartiles]), apnea hypopnea index 31/h [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]) were compared with 12 healthy matched controls. Low dose biplanar X-rays (EOS ® system) were acquired and personalized three-dimensional models of the spine and pelvis were reconstructed.…”

“…Maintaining spinal alignment in close proximity to the vertical is considered optimal to minimise postural muscle activity (Edmondston et al, 2011;Hasegawa et al, 2017;Schwab et al, 2006), optimize gaze (Amabile et al, 2016;Diebo et al, 2016;Duvalbeaupere et al, 1992;Hasegawa et al, 2017), and optimize shoulder function (Crawford and Jull 1993). As the largest component of the spine, the thoracic spine influences postural alignment and function of neighbouring structures, such as the scapulae, upper limbs, and neck.…”
