Timing of the injection therapy to a throwing shoulder

Abstract

We analyzed the physical findings in patients who received short-term inpatient treatment for throwing shoulder injuries (including 76 patients who received injection therapy [injection group] and 105 who did not [non-injection group]), to determine the appropriate timing of the injection therapy. The injection group had a higher proportion of patients with abnormal hyper external rotation test (HERT) results at admission than the non-injection group. In addition, exercise therapy did not improve the results of the combined abduction test (CAT), horizontal flexion test (HFT) or HERT, and the patients received injection therapy 3 to 4 days after admission. As a result, the physical findings at discharge were similar between the injection and non-injection groups, suggesting that the appropriate timing of injection is 3 to 4 days after the start of exercise therapy.
