Introduction: The paper shows the mutual dependencies of height and angles of the neck triangle and selected points of the spine for straightened and habitual postures with the use of a non-contact optical tool. A group of 39 healthy, adult volunteers participated in the study, which was conducted in Warsaw, Poland. Results show relationships between the habitual posture in the sagittal plane, the angle of the triangle between the cervical and upper thoracic kyphosis and the vertical line defined by spine points C7/Th1.
Methods: Measurement system based on photogrammetry was used for spatial determination of specific points. Specially designed non-invasive markers were used. The presented paper shows a new approach for analysis of the geometry of the upper part of the human musculoskeletal system with the use of optical systems in biomedical applications.
Results: Results are presented as series of 14 defined parameters and calculated for habitual and straighten postures. Results were analyzed as a values of correlation coefficients and significance level.
Discussion: An analysis of measurements results based on a triangle represented by three points: two outermost points of the superior nuchal line of the skull and the C7 point are presented. This approach allow to characterize individual positioning of the head in space and is sensitive to many changes in the musculoskeletal system - i.e. the individual way of "standing up straight".
