These postural alterations may negatively influence respiratory biomechanics and breathing control. However, the relationship between smartphone addiction, postural deterioration, and dysfunctional breathing symptoms has not been comprehensively investigated.\n\nParticipants will complete questionnaires assessing smartphone addiction and breathing control, and posture will be evaluated using the New York Posture Rating Chart.
