Relationship Between Forward Head Posture and Sagittal Lumbopelvic Alignment Among Smartphone Users

4 juni 2026 bijgewerkt door: Deraya University

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.

Gedetailleerde beschrijving

Forward head posture is considered one of the commonly occurring musculoskeletal postural abnormalities. It is characterized by an anterior position of the head relative to the body's line of gravity in the sagittal plane. This altered posture may increase mechanical load on cervical joints, ligaments, and surrounding soft tissues.

Sagittal spinal and lumbopelvic alignment are important components of global postural balance. Changes in one spinal region may influence adjacent regions through compensatory mechanisms that help maintain horizontal gaze and keep the body's center of gravity within the base of support.

Smartphone use is commonly associated with prolonged neck flexion and altered head posture. Therefore, this study aims to investigate the relationship between craniovertebral angle, as an indicator of forward head posture, and sagittal lumbopelvic alignment parameters among smartphone users.

A total of 85 male participants with forward head posture will be recruited from outpatient clinics and students of the Faculty of Physical Therapy, Sphinx University. Forward head posture will be assessed using craniovertebral angle measured by the APECS mobile application. Sagittal lumbopelvic alignment will be assessed using the Spine3D LiDAR system by Sensor Medica, including lordotic angle, lumbar arrow, and trunk inclination.

Interventie / Behandeling
Male Smartphone Users With Forward Head Posture
Male participants aged 18 to 35 years who use smartphones for at least 4 hours per day for at least 6 months and have forward head posture, defined by craniovertebral angle equal to or less than 50 degrees. Participants will be assessed for craniovertebral angle and sagittal lumbopelvic alignment parameters during a single assessment session.
Diagnostische toets: Craniovertebral Angle Assessment Using APECS Mobile Application
The craniovertebral angle will be measured using the APECS mobile application to assess forward head posture. Participants with a craniovertebral angle equal to or less than 50 degrees will be considered to have forward head posture.
Diagnostische toets: Sagittal Lumbopelvic Alignment Assessment Using Spine3D LiDAR
Sagittal lumbopelvic alignment will be assessed using the Spine3D LiDAR system by Sensor Medica. The measured parameters will include lordotic angle, lumbar arrow, and trunk inclination.
