title: Effects of repeated steroid injection at subacromial bursa with different interval.
abstract: OBJECTIVE
  To evaluate the effects of repeated steroid injection at subacromial bursa with different interval for patient with periarticular shoulder disorder.
  
  
  METHODS
  Group A (n=10) received subacromial bursa injection only on their first visit, group C (n=10) received the injection on their first visit and one week later, and group B (n=10) received the injection on their first visit and two weeks later. All injections were done with a combination of 40 mg (1.0 mL) of triamcinolone and 5.0 mL 0.5% lidocaine (6 mL total). We examined the active range of motion (AROM) of the shoulder joint, visual analogue scale (VAS), and shoulder disability questionnaire (SDQ) at baseline at 1, 2, and 4 weeks after the initial injection.
  
  
  RESULTS
  In VAS, comparing the changes in VAS between groups, group B showed significant improvements compared with group A or C at 4 weeks after the initial injection (p<0.05). In SDQ, comparing the changes in SDQ between the groups, group B and C showed more improvement than group A at 4 weeks after the initial injection, but these results were not statistically significant (p>0.05). In AROM, comparing the changes in AROM of external rotation between groups, group B and C showed significant improvement compared with group A at 4 weeks after the initial injection (p<0.05).
  
  
  CONCLUSIONS
  It may be more effective in pain relief for patients with periarticular disorder to receive subacromial bursa injections twice with 2-week interval, as opposed to once.
