The present study demonstrated statistically significant improvements in pain, range of motion (ROM), and functional disability in both groups; however, participants receiving telerehabilitation with self-Mulligan technique exhibited significantly greater improvements compared to those receiving telerehabilitation alone. These findings highlight the added value of incorporating manual therapy concepts, even in a self- applied or remotely guided format, into rehabilitation programs for patients with subacromial pain syndrome (SAPS). The significant reduction in pain scores (VAS) and improvement in ROM across all planes in Group A can be explained by the biomechanical correction principle of the Mulligan Concept, particularly Mobilization with Movement (MWM). This technique is believed to correct minor positional faults in the glenohumeral joint, thereby restoring normal arthrokinematics, reducing nociceptive input, and improving movement efficiency. When combined with structured telerehabilitation exercises, it likely created a synergistic effect addressing both mechanical dysfunction and neuromuscular control.(25)
