WORC score
There was improvement of the WORC score in the case of each group 1, 3 and 6 months. The P-value analysis in WORC was determined by applying the Generalized Estimating Equation (GEE) in order to assesses the difference between the groups at any point in time; the significance level being set at 0.05. It was determined that there were no significant differences in WORC score between the 2 trial groups at any point in time. At pre-injection time, a WORC score of 43.6 ± 15.02 was recorded for the HVCI group. In the case of the VLVCI group a score of 48.39 ± 15.71 (P = 0.221) was recorded (Table Result of Mean of VAS, WORC and DASH within group at difference time compared after baseline, 2 weeks and 1-, 3- and 6-months follow-up.* The data was statistically significant (Result of VAS during activity outcomes at pre injection, post injection 15 min, Percentage difference improvement after 15 min, 2 weeks and 1, 3 and 6 months, WORC at 1 month and DASH at 1, 3 and 6 months between high volume and very low volume corticosteroid injection.Mean WORC score by the progression time to treatment with SCI.
