Correlation of Scapular motion, Shoulder Pain and Proprioceptive Accuracy with Upper Limb Disability in Modified Radical Mastectomy patients - A Cross-Sectional Study

Modified Radical Mastectomy often leads to long-term shoulder complications due to surgical disruption of soft tissues, altered scapulothoracic mechanics, postoperative immobilization, and pain-related protective patterns. These changes may compromise scapular motion, reduce shoulder proprioceptive accuracy, and increase upper limb disability, affecting daily functional activities and quality of life.

This study aims to evaluate the relationship between scapular kinematics, shoulder pain, and joint position sense with upper limb disability in women who have undergone MRM. Scapular motion will be assessed using standardized clinical measures, shoulder pain will be measured using validated pain scales, proprioceptive accuracy will be tested through active joint repositioning, and upper limb disability will be quantified using a functional outcome questionnaire. By analyzing the correlations among these variables, the study seeks to identify key contributors to post-mastectomy shoulder dysfunction.

Understanding these interrelationships will help clinicians recognize early biomechanical and sensory deficits and guide targeted physiotherapy interventions. The findings may support the development of more specific rehabilitation protocols to reduce pain, improve neuromuscular control, restore scapular mechanics, and enhance functional recovery in post-MRM patients
