STUDY DESIGN: Randomized clinical trial. OBJECTIVE: To compare the effectiveness of an­terior versus posterior glide mobilization techniques for improving shoulder external rotation range of motion (ROM) in patients with adhesive capsulitis. BACKGROUND: Physical therapists use joint mobilization techniques to treat motion impair­ments in patients with adhesive capsulitis. However, opinions of the value of anterior versus posterior mobilization procedures to improve external rotation ROM differ. METHODS AND MEASURES: Twenty consecu­tive subjects with a primary diagnosis of shoulder adhesive capsulitis and exhibiting a specific external rotation ROM deficit were randomly assigned to 1 of 2 treatment groups. All subjects received 6 therapy sessions consisting of application of therapeutic ultrasound, joint mobilization, and upper-body ergometer exercise. Treatment differed between groups in the direction of the mobilization technique performed. Shoulder external rotation ROM mea­sured initially and after each treatment session was compared within and between groups and analyzed using a 2-way ANOVA, followed by paired and independent t tests. RESULTS: There was no significant differ­ence in shoulder external rotation ROM between groups prior to initiating the treatment program. A significant difference between groups (P = .001) was present by the third treatment. The individu­als in the anterior mobilization group had a mean improvement in external rotation ROM of 3.0° (SD, 10.8°; P = .40), whereas the individuals in the poste­rior mobilization group had a mean improvement of 31.3° (SD, 7.4°; P<.001). CONCLUSIONS: A posteriorly directed joint mobilization technique was more effective than an anteriorly directed mobilization technique for improving external rotation ROM in subjects with adhesive capsulitis. Both groups had a significant decrease in pain.
