Brief Summary

The aim of this study is to investigate the effects of smartphone addiction on postural problems and breathing control in healthy university students. Excessive smartphone use has been associated with forward head posture, thoracic postural changes, and musculoskeletal complaints. 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. Participants 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.

Conditions

Smartphone Addiction; Postural Disorders; Dysfunctional Breathing

Keywords

smartphone addiction; posture; breathing control

Outcome Measures

Primary Outcomes (1)

• Presence of postural problems

  Posture will be evaluated using the New York Posture Rating Chart (NYPRC). Participants will be categorized according to posture status. Lower scores indicate poorer posture.

Other: Observational Assessment

Non-addicted group

Participants without smartphone addiction according to Smartphone Addiction Scale-Short Form cutoff values.

Other: Observational Assessment

Interventions

Observational Assessment OTHER

Participants will complete questionnaires assessing smartphone addiction, physical activity level, and breathing control. Postural assessment will be performed using the New York Posture Rating Chart. The study will investigate the association between smartphone addiction, postural problems, and breathing control in university students.
