Summary

This study looked at 85 young men who use smartphones a lot to see if forward head posture is linked to changes in lower spine alignment. Researchers measured head angle with a phone app and spine shape with a 3D scanner. The goal was to understand how screen time might affect posture, not to test a treatment.
