Abstract

Background: Frozen shoulder syndrome is characterized by a progressive decline in both active and passive glenohumeral mobility. Scapular mobilization and posterior capsular stretching are commonly applied physical therapy interventions in its management.
Purpose: To compare the effects of scapular mobilization versus posterior capsular stretching in patients with frozen shoulder.
Patients and Methods: Thirty-four participants (aged 40–65years) diagnosed with unilateral frozen shoulder were randomly allocated into two equal experimental groups: scapular mobilization group and posterior capsular stretching group. Both groups were also treated with infrared radiation, ultrasound therapy, glenohumeral mobilization, and pendulum exercises. All patients received treatment three times a week for duration of four weeks.
Results: Both groups demonstrated significant improvements in range of motion, pain, disability, and posterior capsular tension (P<0.001). However, no significant between-group differences were observed for most variables, except for external rotation, which showed a significant improvement in the scapular mobilization group (P=0.017).
Conclusion: Both techniques are effective treatment options for frozen shoulder, with scapular mobilization potentially offering additional benefit for improving external rotation.
