The Correlation Between Neck Posture and Scapular Posture & the Effect Stabilization Exercises for the Scapula

March 24, 2026 updated by: JEUNGYEOL JEONG, Hallym University Dongtan Sacred Heart Hospital

The Effect of Scapular Balancing Exercise in Neck-scapular Dysfunction -Relationship Between Neck-scapular Posture ＆ Axioscapular Muscles-

Recently, many office workers and young people have postural abnormalities, including forward head posture (FHP) and rounded shoulder posture (RSP). Most of these patients often complain of pain in the entire scapular area, including the trapezius muscle. Few studies examined the effectiveness of intervention exercises often used by clinicians to correct posture in these patients through training protocols.

To compare and analyze the changes in scapular position between normal people and patients with FHP and RSP and to evaluate the effect of exercise therapy for 3 months in these patients, including clinical results and changes in scapular position and cervical angle through objective data.
