Summary

This study looked at 105 university students to see if smartphone addiction is linked to changes in neck angle, neck movement sense, and balance. Participants filled out a smartphone addiction survey and had their neck posture, proprioception, and balance measured. The goal was to better understand how excessive phone use might affect physical health, but no treatment or intervention was tested.
