Effectiveness of a Targeted Cervico-Scapular Physiotherapy Intervention on Smartphone Induced Postural Deviations and Musculoskeletal Symptoms: A Randomized Controlled Trial

Abstract Background: Smartphone-induced forward head posture, scapular dyskinesis, and associated musculoskeletal symptoms represent a growing public health concern among young adults. While postural dysfunction is well-documented, evidence-based intervention protocols integrating cervical stabilization, scapular motor control, and thoracic mobility remain limited. This randomized controlled trial evaluates the effectiveness of a targeted cervico-scapular physiotherapy intervention on postural alterations and functional outcomes in smartphone users. Objective: To investigate the effectiveness of a structured 8-week cervico-scapular physiotherapy intervention (integrating cervical stabilization exercises, scapular stabilization and motor control training, thoracic mobility work, and smartphone ergonomics education) compared to standard care on smartphone-induced postural deviations and musculoskeletal symptoms.
