Abstract Background: It is clear that therapeutic exercise plus mobilization have significant benefits on range of motion in frozen shoulder however it is important to consider the patient's symptoms and the stage of the condition and suggest if the disease prognosis is affected by treatment. Aim of Study: To compare the combined effect of shoulder mobilization and therapeutic exercises on pain, range of motion, and overall shoulder functions between stage II and stage III frozen shoulder. Material and Methods: Thirty patients referred as frozen shoulder, were divided according to their stage of illness equally into two groups; group A (stage II) and group B (stage III). Both groups were treated with mobilization, stretching exercises, active exercise and Codman pendulum exercises and that was 2 times per week for successive two months. Each patient was assessed for shoulder ROM using universal goniometer pretreatment, post 6 sessions and post treatment and pain and disability using shoulder pain and disability index (SPADI) pretreatment and post treatment. Results: There was significant effect of mobilization and therapeutic exercises on pain and overall shoulder functions in both groups with more significant effect in group A compared with group B (p=0.0001). Also there was significant effect on shoulder ROM of flexion and abduction in group A com-pared with that of group B (p=0.0001). But there was no significant difference in shoulder internal rotation and external ROM between both groups (p=0.8 & p=0.12). Whereas there was a significant increase in shoulder extension ROM of group B compared with that group A (p=0.001). Conclusion: The combined effect of mobilization and therapeutic exercises has significant effect on pain and overall shoulder functions in stage II frozen shoulder than stage III and a significant effect on shoulder ROM in both stages.
