Forward head posture is a common postural abnormality characterized by anterior positioning of the head in the sagittal plane. This posture may increase biomechanical stress on the cervical spine and may be associated with compensatory changes in spinal and lumbopelvic alignment.
This observational study will investigate the relationship between forward head posture and sagittal lumbopelvic alignment among male smartphone users aged 18 to 35 years. Craniovertebral angle will be measured using the APECS mobile application, and sagittal lumbopelvic alignment parameters will be measured using the Spine3D LiDAR system.
