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. Binary logistic regression analysis will be performed to determine whether smartphone addiction independently predicts postural problems. Additionally, multiple linear regression analyses will be conducted to examine the association between smartphone addiction, posture, and breathing control.",[71,72,73],"Smartphone Addiction","Postural Disorders","Dysfunctional Breathing",[75,76,77],"smartphone addiction","posture","breathing control","2026-05-22",{"date":80,"type":81},"2026-05-29","ACTUAL",{"date":83,"type":81},"2026-04-05",{"date":85,"type":66},"2026-06-20",{"name":5,"class":6},1]
