UNASSIGNED: This randomised clinical trial was conducted in 60 patients. The treatment group received combined pulsed radiofrequency (PRF) on suprascapular nerve (SN) and axillary-circumflex nerve (ACN). The control group received PRF on SN only. The primary outcome was pain intensity measured by the Numerical Rating Scale (NRS). The secondary outcomes were the Shoulder Pain and Disability Index (SPADI), the Constant-Murley range of motion scale and Disability of the Arm, Shoulder and Hand (DASH) scale. The patients were monitored at the baseline visit and at 1, 3, 6 and 9 months. A mixed ordinal regression model was estimated to evaluate the association between the study group and pain measured with NRS.
UNASSIGNED: A global decrease in pain at the end of the study was noted. The global baseline NRS was 8.4, and the global final NRS at 9 months of follow-up was 6.2. Combined PRF on SN and ACN was not associated with lower NRS pain scores compared to single SN PRF [odds ratio (OR) =1.04, 95% confidence interval (CI) 0.91-1.20, P = 0.507]. Secondary outcomes showed no significant differences: SPADI (OR = 1.04, 95% CI 0.92-1.18), Constant-Murley (OR = 1.01, 95% CI 0.90-1.14), DASH (OR = 1.04, 95% CI 0.92-1.17).
UNASSIGNED: Combined PRF applied to SN and ACN was not superior to PRF applied to SN alone.
■这项随机临床试验在60名患者中进行。治疗组接受肩胛骨上神经(SN)和腋窝回旋神经(ACN)联合脉冲射频(PRF)治疗。对照组仅在SN上接收PRF。主要结果是通过数值评定量表(NRS)测量的疼痛强度。次要结果是肩痛和残疾指数(SPADI),手臂的恒定-Murley运动范围和残疾,肩和手(DASH)刻度。在基线访视和1、3、6和9个月时监测患者。估计了混合序数回归模型来评估研究组与使用NRS测量的疼痛之间的关联。
■观察到在研究结束时疼痛总体减轻。全球基线NRS为8.4,随访9个月时全球最终NRS为6.2。与单一SNPRF相比,SN和ACN的联合PRF与较低的NRS疼痛评分无关[比值比(OR)=1.04,95%置信区间(CI)0.91-1.20,P=0.507]。次要结果没有显着差异:SPADI(OR=1.04,95%CI0.92-1.18),Constant-Murley(OR=1.01,95%CI0.90-1.14),DASH(OR=1.04,95%CI0.92-1.17)。
■应用于SN和ACN的组合PRF并不优于单独应用于SN的PRF。
