Abstract | BACKGROUND: MATERIALS AND METHODS: This single-center, randomized, single-blind, non-inferiority trial included patients with shoulder pain and positive multiple clinical tests supporting the diagnosis of impingement syndrome. All 52 patients received subacromial injections, with either high-volume corticosteroid injections (HCI) (10 mL total volume of 1% lidocaine plus 40 mg TA) in 26 patients or low-volume corticosteroid injections (LCI) (4 mL total volume of 1% lidocaine plus 40 mg TA) in 26 patients. The demographic data were reported with the primary outcomes being VAS and WORC scores measured at 30 min, then 2 and 8 weeks after receiving the injections. A non-inferiority margin of 13% was assumed. RESULTS: Fifty-two patients (26 patients per group) were enrolled in the HCI and LCI. Mean VAS and WORC scores of HCI and LCI at baseline were 6.96, 33.85, 6.81 and 36.54, respectively. The mean VAS measured at 30 min, 2 and 8 weeks was 4.04, 2.08 and 1.20, respectively, in HCI group and 2.65, 1.95 and 1.26, respectively, in LCI group. The mean WORC at 2 and 8 weeks was 67.46 and 81.74, respectively, in HCI group and 65.42 and 80.12 in LCI group. These were not statistically significantly different (P > 0.05 in all). CONCLUSION: LEVEL OF EVIDENCE: Level I.
