Effect of Mobilization With Movement on the Glenohumeral Joint Positional Fault in Subacromial Impingement.

Abstract

Introduction Subacromial impingement (SAI) is a prevalent shoulder condition characterized by mechanical compression within the subacromial region. It presents with symptoms like shoulder pain and restricted motion, impacting a significant portion of the population. Neer's classification delineates three progressive stages of SAI, ranging from bursa edema to chronic rotator cuff tears. The etiology involves intrinsic and extrinsic factors, leading to altered kinematics and impingement. The study aims to determine the effect of mobilization with movement (MWM) on the glenohumeral joint positional fault in patients with SAI. Materials and methods The study comprised 80 participants diagnosed with SAI, selected based on the inclusion and exclusion criteria, and randomly divided into two groups, each consisting of 40 subjects. Group A received conventional therapy, while Group B received MWM in addition to conventional therapy. Treatment sessions, lasting 45 minutes, were administered five times weekly for four weeks. Pre- and post-treatment assessments included the visual analog scale (VAS), range of motion (ROM), acromion humeral distance (AHD), and acromion tuberosity index (ATI). Results The results demonstrated that there was an extremely significant improvement in VAS, shoulder ROM, and ADH in both groups, with a p-value of 0.0001, except for the ATI, which showed significant improvement in Group B with a p-value of 0.0001 compared to Group A. Conclusions Based on statistical analysis, the study found that MWM significantly improved joint positioning fault and has been beneficial in reducing pain and improving ROM.
