Background: Subacromial impingement syndrome (SIS) is a common shoulder disorder often associated with altered scapular mechanics, reduced upper limb strength, and cervical spine dysfunction. Neck-related impairments may influence upper extremity function and contribute to persistent shoulder symptoms. Objective: To determine the correlation among the Neck Disability Index (NDI), grip strength, and scapular position in individuals with subacromial impingement syndrome. Methods: A cross-sectional analytical study was conducted on individuals diagnosed with SIS. Neck disability was assessed using the Neck Disability Index. Grip strength was measured using a hand-held dynamometer, and scapular position was evaluated using a standardized clinical assessment method. Correlation analysis was performed to examine the relationship among NDI scores, grip strength, and scapular position. Results: A significant positive correlation was observed between NDI scores and altered scapular position, indicating increased neck disability with greater scapular malalignment. A significant negative correlation was found between NDI scores and grip strength, suggesting reduced hand strength with higher neck disability. Additionally, altered scapular position demonstrated a significant association with decreased grip strength. Conclusion: The findings suggest that neck disability, grip strength, and scapular position are interrelated in individuals with subacromial impingement syndrome. These results highlight the importance of comprehensive assessment and integrated rehabilitation approaches addressing cervical spine function, scapular control, and upper limb strength in the management of SIS.
