The forward head posture is found to be influenced by Craniovertebral Angle (CV) and shoulder angle (SA) that in turn causes rounded shoulder. Conclusion A high level of smartphone addiction reduces the craniovertebral angle and increases scapular dyskinesis. What the Craniovertebral Angle Means As the head drifts forward, so does the tragus of the ear relative to the base of the cervical spine (C7 spinous process), which is what the craniovertebral angle measures. Craniovertebral Angle and Cervical Lordosis. @article{Lau2010MeasurementOC, title={Measurement of craniovertebral angle with Electronic Head Posture Instrument: Criterion validity. The clivo-axial angle is measured by drawing a line along the posterior (back, or when lying more horizontal, the top) side of the lower clivus and intersecting that line with a line drawn on the posterior side of the axis. In fact the unfavourable angle of the C1 ring matching makes it difficult or . Now, we have got the complete detailed . Subjects with FHP have a smaller CVA and show increased flexion of lower cervical vertebrae 8). The longus colli (LCo) muscle is an important muscle to control head posture. Forward Head Posture (FHP) occurs when changes in spinal alignment due to rounded shoulders and a decreased cranial vertebral angle (CVA) occur. Craniometric measurements used in radiologic assessment of CVJ anomalies include the Chamberlain line, Wackenheim clivus baseline, Welcher basal angle, and atlantooccipital joint axis angle.
