Background: The traditional treatment protocol in adhesive capsulitis cases is physical therapy agents and a home exercise program. The extensive majority of patients respond to conservative treatment, but the painful rehabilitation program makes it inconvenient for individuals to fully comply with the treatment. In order to reduce pain and spasm, intraarticular injections or suprascapular nerve block may be effective before the rehabilitation program. Objectives: To investigated the effect of suprascapular nerve block (SNB), which is added to standard physical therapy on pain, functionality and range of motion in patients with adhesive capsulitis (AC). Design: Retrospective study. Methods: This study included 46 patients who were treated for AC. Patients in both groups were given 15 season physical therapy and home exercise. The treatment group consisted of patients who underwent multiple SNB in addition to physical therapy and home exercise. Datas were analyzed retrospectively. Results: The Visual Analogue Scale (VAS), ROM, Shoulder Pain and Disability Index (SPADI) and Constant scores in both groups after treatment and at the third month follow-up (P<.001). In the comparison between the groups, it was determined that the improvement in VAS, ROM and SPADI scores in the treatment group at the 3-month control was statistically significant (P<.05). Conclusion: Multiple SNB added to physical therapy and home exercise program in cases of AC may be effective in terms of pain control, increasing joint range of motion and improving functionality.
