    Area of Science:

    • Biomedical Engineering
    • Radiology
    • Orthopedics

    Background:

    • Accurate spinal posture assessment is crucial for diagnosing and managing conditions like scoliosis.
    • Traditional methods like X-rays involve radiation exposure and can be costly.
    • Digital Image-Based Postural Assessment (DIPA) offers a potential non-invasive alternative.

    Purpose of the Study:

    • To evaluate the accuracy of palpatory methods for identifying spinal anatomical points compared to X-ray.
    • To validate the DIPA software's ability to classify spinal posture in the frontal plane against X-ray standards.
    • To assess the intra- and inter-evaluator reproducibility of the DIPA software for spinal assessment.

    Main Methods:

    • 24 subjects underwent consecutive postural assessments and spinal X-rays in the frontal plane.
    • Palpation and reflective markers identified spinous processes (SP); photographic records were acquired.
    • DIPA software calculated scoliosis arrows (DIPA-SA), compared with X-ray derived scoliosis arrows (X-SA) and Cobb angles.

    Main Results:

    • No significant differences were found between palpated/marked SP and X-ray identified SP locations.
    • Significant correlations were observed between DIPA-SA and Cobb angles (dorsal/lumbar), and between DIPA-SA and X-SA (dorsal/lumbar).
    • DIPA and X-ray protocols showed high agreement in posture classification and excellent intra- and inter-evaluator reproducibility.

    Conclusions:

    • The DIPA protocol is a valid, simple, practical, and low-cost non-invasive tool for evaluating spinal posture in the frontal plane.
    • DIPA provides reproducible measurements, making it a reliable method for clinical use.
    • This digital method offers a radiation-free alternative for scoliosis screening and monitoring.
