A study of interdependence of geometry of the nuchal neck triangle and cervical spine line in the habitual and straightened postures

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”.
