Comparison of the outcomes of two different exercise programs on frozen shoulder

Abstract

Objectives: The aim of the study was to compare the effects of two different exercise programs on pain, range of motion (ROM), and functional results in frozen shoulder.

Methods: Twenty-two female and 7 male patients [mean age 52.1 years (range 38-65 years)] were randomly allocated into two groups: 14 in the first group and 15 in the second group. The patients were treated for 6 weeks (30 sessions) at hospital under the supervision of physical therapist. Both groups were treated with transcutaneous electrical nerve stimulation, cold pack, and nonsteroidal antiinflammatory drugs; and were given glenohumeral ROM exercises. The scapulothoracic exercises were performed only by the second group. Functional results were assessed using the modified Constant score, pain was assessed using visual analog scale (VAS), and ROM was measured with a goniometer. Assessments were performed before treatment and repeated at 6 and 12 weeks of treatment.

Results: In both groups, the Constant score and ROM were increased, and VAS was decreased at the end of 6 and 12 weeks. The modified Constant score was not significantly different between the groups before and after treatment. VAS score was better in the second group at 6 weeks (p<0.01). Improvement in ROM was significantly better in the second group at 12 weeks (p=0.005).

Conclusion: In addition to glenohumeral ROM exercises, scapulothoracic exercises contribute to decreasing pain and increasing ROM in patients with frozen shoulder.
