Introduction

Physiological aging involves progressive changes in the spine, with possible alterations in alignment and sagittal balance. In this context, physical activity emerges as a key factor in preventing postural deterioration.

A recent study published in Frontiers in Medicine analysed morphological differences in the spine in elderly women with different levels of physical activity, providing relevant scientific evidence on the importance of accurate monitoring without radiological exposure.

The role of Spine 3D technology

The study used Spine 3D by Sensor Medica, a three-dimensional optoelectronic system based on LiDAR technology, to non-invasively assess the morphology of the spine in the frontal and sagittal planes.

Thanks to the 3D reconstruction of the dorsal surface and the identification of specific anatomical landmarks, Spine 3D allows for precise measurement of postural parameters, demonstrating high reliability and reproducibility.

The results showed that subjects with low levels of physical activity had a significant increase in sagittal imbalance and trunk tilt compared to those who engaged in moderate or intense physical activity, confirming the clinical value of three-dimensional postural assessment in the elderly population.

Conclusions

This study reinforces the importance of physical activity in maintaining sagittal alignment of the spine during ageing and highlights the strategic role of non-invasive technologies such as Spine 3D for screening, monitoring and preventing postural alterations.

The integration of advanced, radiation-free systems into clinical practice is now a fundamental resource for accurate, safe and repeatable postural assessment over time.
