Spinal deformities have been reported unclearly on clinical examination. No study quantitatively assessed upright posture defining specific alterations of LOPD various phenotype. Objective: Identify postural abnormalities in a homogeneous group of LOPD patients using 3D Stereophotogrammetry (St) and x-Ray (xR). Methods: Seven LOPD siblings were recruited. They were assessed by clinical scales and, in upright posture, using xR and 3D-St with a new marker set protocol. Fourteen healthy individuals, age and sex-matched, were used as controls for St-parameters; normative xR-values were found in literature. Results: LOPD patients showed a significant weakness of trunk and tibialis anterior muscles. Statistical analysis of St-parameters showed a larger ankle, knee, elbow, dorsal, S2-C7, heel-S2-C7, heel-S2-nasion angles and a lower sagittal vertical axis (SVA) than controls. xR-analysis highlighted an absence of scoliosis and a lower occipito-cervical, C2-C7 cervical and Cobb dorsal angles, and a trend to lower lumbar lordosis and SVA compared to normal values. Significant correlation was found in dorsal and lumbar angles calculated using xR-markers placed on spiny apophysis, xR-centre of vertebral bodies, Cobb-method and St-markers. Conclusion: This is the first quantitative study of postural abnormalities in LOPD patients using 3D-St and xR, highlighting sagittal standing alignment changes, difficult to assess to direct exam.Our new St-protocol showed a high reliability compared to xR. Further studies on larger population of LOPD might confirm the usefulness of these instrumental methods for monitoring disease course.<\/jats:p>","DOI":"10.3233\/jnd-210663","type":"journal-article","created":{"date-parts":[[2021,6,11]],"date-time":"2021-06-11T10:43:44Z","timestamp":1623408224000},"page":"979-988","source":"Crossref","is-referenced-by-count":15,"title":["Quantitative
