ABSTRACT Background and Purpose This study investigated the effect of Global Postural Re‐Education (GPR) versus conventional physical therapy in text neck syndrome (TNS). A prospective, single‐blinded, parallel‐group randomized controlled trial design was used. Methods Sixty participants with TNS (aged 18–40 years) were randomly assigned to either conventional treatment or GPR plus conventional treatment. Both groups received supervised therapy for three sessions per week over 4 weeks. Outcome measures included craniovertebral and shoulder angles assessed by photogrammetry, pain intensity via Visual Analog Scale, and Cervical Range of Motion via a smartphone application (Clinometer). Measured before and after the intervention. Results Within‐group analyses showed significant improvements in pain and CROM in both groups ( p < 0.001). However, the between‐group analysis revealed no superiority of GPR for pain or CROM ( p > 0.05). In contrast, GPR demonstrated statistically significant superiority in postural correction, with greater improvements in craniovertebral angle (MD: 2.14°; 95% CI: 0.69–3.59; p = 0.005) and shoulder angle (MD: 3.2°; 95% CI: 0.33–6.07; p = 0.03), exceeding MCID thresholds and indicating clinically meaningful benefits. However, these findings should be interpreted with caution because of the longer session duration in the GPR group. Discussion Incorporating Global Postural Reeducation (GPR) into conventional treatment provided significant additional benefits for postural parameters (craniovertebral and shoulder angles) in individuals with text neck syndrome. However, GPR demonstrated no added superiority over conventional treatment alone regarding pain intensity and cervical range of motion outcomes.
