Objective>
To evaluate the improvement of pain and range of motion (ROM) in non-injected shoulder after intra-articular corticosteriod injection to one side in bilateral adhesive capsulitis.
Method>
This is retrospective comparative study. Participants were bilateral primary adhesive capsulitis patients (n=25), who had ultrasound-guided corticosteroid injection in one shoulder. Outcome measurements were visual analogue scale (VAS) and passive ROM (①abduction, ②external rotation, ③hyperextension and internal rotation) evaluated at pre and post-injection. Wilcoxon signed rank test was performed to compare the changes of pain and passive ROM between pre and post-injection in injected and non-injected shoulder, respectively.
Result>
Of the 25 patients, 8 were men, 17 were women. Mean age was 53.24±6.63. Mean value of symptom duration was 5.32±1.93months. Mean value of triamcinolaone acetonide dose was 29.6±2mg. Mean value of follow-up days after injection was 18.24±4.48days. For injected shoulder, VAS and passive ROM (①abduction, ②external rotation, ③hyperextension and internal rotation) were improved with statistically significance. Interestingly, VAS and passive ROM (①external rotation) were also improved for non-injected shoulder with statistically significance (table 1).
Conclusion>
This study shows intra-articular corticosteroid injection improves outcomes of non-injected shoulder. Therefore, in bilateral adhesive capsulitis, we suggest that clinicians would be better to observe the non-injected shoulder after one side injection rather than do injection both shoulders simultaneously. |
