Identification and prevention of postural alterations: statistical analysis of data collected by a “LiDAR” equipment. Capabilities and limitations

Office workers are more at risk of prolonged sitting. In Italy, according to Eurost estimates, people tend to work an average of about 37 hours a week, which is equivalent to 7.4 hours a day if we consider five working days per week. The aim of the study was to evaluate the possible association between sedentary work/VDT and the presence of alterations affecting the musculoskeletal system, using a non-invasive tool, with faster execution and allowing for three-dimensional reconstruction. In this study, a sample of 230 subjects was analyzed using LiDAR technology to reconstruct the spine in 3D and analyze any postural anomalies. The results revealed that, in general, the study sample presents a prevalence of postural anomalies in the more advanced age groups, such as scoliosis, hyperkyphosis and hypolordosis. The analysis highlighted a slight prevalence of load on the right feet compared to the left, suggesting potential differences in posture between the two genders and in different age groups. The results offer an interesting overview on the use of LiDAR technology to analyze postural anomalies, highlighting some patterns consistent with the literature. Despite some limitations, the analysis suggests that LiDAR could have significant potential in the field of postural diagnostics, although with some technical challenges to be addressed.
