Abstract
Objective
To investigate the treatment efficacy between low and high dose of triamcinolone acetonide in the treatment of ultrasonographic-guided subacromial bursa injection.
Method
Forty two patients with periarticular shoulder disorders were randomly assigned to receive injection with 10 mg (group 1, 20 patients) or 40 mg (group 2, 22 patients) triamcinolone acetonide. After a single injection, participants were followed up for 6 weeks. Treatment efficacy was measured upon pre-treatment and post-treatment on week 1, 3, 6, using visual analog scale for average pain intensity during 24 hours (24 h VAS), Shoulder Function Assessment scale (SFA), Shoulder Disability Questionnaire (SDQ), and active range of motion (AROM). Participants and the assessor were blinded for group assignment.
Results
Six weeks after injection, the 24 h VAS, the SFA, the SDQ, and the AROM (internal rotation, external rotation, and abduction) showed a significantly greater improvement in group 2 than group 1 (p<0.05).
Conclusion
This study showed that in the treatment of periarticular shoulder disorders greater pain relief and functional improvement were obtained with a dose of 40 mg triamcinolone acetonide than with a dose of 10 mg. (J Korean Acad Rehab Med 2009; 33: 402-407)
