BACKGROUND Shoulder pain is a common complication of hemiplegic patients that can interrupt their rehabilitation program and is associated with poorer outcomes. The usefulness of the suprascapular nerve block. (SSNB) in the stroke population has been suggested, but some concerns still remain. OBJECTIVES To investigate the effect of SSNB on pain intensity and passive range ofmotion (PROM) in patients with hemiplegic shoulder pain (HSP). STUDY DESIGN A prospective, double blind, randomized controlled trial was conductedin 34 stroke patients with HSP. They were randomly divided into three groups: Localanesthetic (LA) injection into the trapezius muscle (placebo group), LA injection into thesuprascapular notch, and LA and corticosteroid (CS) injections into the suprascapularnotch.The main outcome was visual analog scale (VAS) scores evaluated before andafter administration of the injection at 1 hour, 1 week, and 1 month. RESULTS There were significant decreases in the VAS scores with all three injections at all follow-up time points (p: 0.001 for the placebo group, p <0.001 for the LA group, and p <0.001 for the LA+CS group). When changes in VAS scores were compared between the groups, the LA+CS group demonstrated a higher decrease in VAS than the placebo group. Improvement in the PROM was seen only in the LA and LA+CS groups. CONCLUSIONS The findings of this study support the use of an SSNB with or without CS, to increase the range of motion in the affected shoulder, especially during the rehabilitation period.

肩cap上神经阻滞在偏瘫性肩痛中：比较安慰剂，局部麻醉药和皮质类固醇注射的有效性-一项随机对照研究。

背景技术肩痛是偏瘫患者的常见并发症，可能会中断他们的康复计划，并导致预后较差。肩cap上神经阻滞的有用性。（SSNB）在中风人群中已被提出，但仍存在一些担忧。目的探讨SSNB对偏瘫肩痛（HSP）患者疼痛强度和被动运动范围（PROM）的影响。研究设计对34例HSP卒中患者进行了一项前瞻性，双盲，随机对照试验。他们被随机分为三组：斜方肌局部注射（LA）（安慰剂组），肩cap上凹口注射LA，肩LA上凹口注射LA和皮质类固醇（CS）。主要结果是在注射1小时，1周和1个月之前和之后评估的视觉模拟量表（VAS）评分。结果在所有随访时间点，所有三种注射的VAS评分均显着降低（p：安慰剂组为0.001，LA组为p <0.001，LA + CS组为p <0.001）。比较两组间的VAS评分变化后，LA + CS组的VAS下降幅度高于安慰剂组。仅在LA和LA + CS组中看到PROM有所改善。结论本研究的结果支持在有或没有CS的情况下使用SSNB，以增加患病肩膀的运动范围，尤其是在康复期间。结果在所有随访时间点，所有三种注射的VAS评分均显着降低（p：安慰剂组为0.001，LA组为p <0.001，LA + CS组为p <0.001）。比较两组间的VAS评分变化后，LA + CS组的VAS下降幅度高于安慰剂组。仅在LA和LA + CS组中看到PROM有所改善。结论本研究的结果支持在有或没有CS的情况下使用SSNB，以增加患病肩膀的运动范围，尤其是在康复期间。结果在所有随访时间点，所有三种注射的VAS评分均显着降低（p：安慰剂组为0.001，LA组为p <0.001，LA + CS组为p <0.001）。比较两组间的VAS评分变化后，LA + CS组的VAS下降幅度高于安慰剂组。仅在LA和LA + CS组中看到PROM有所改善。结论本研究的结果支持在有或没有CS的情况下使用SSNB，以增加患病肩膀的运动范围，尤其是在康复期间。LA + CS组的VAS下降幅度高于安慰剂组。仅在LA和LA + CS组中看到PROM有所改善。结论本研究的结果支持在有或没有CS的情况下使用SSNB，以增加患病肩膀的运动范围，尤其是在康复期间。LA + CS组的VAS下降幅度高于安慰剂组。仅在LA和LA + CS组中看到PROM有所改善。结论本研究的结果支持在有或没有CS的情况下使用SSNB，以增加患病肩膀的运动范围，尤其是在康复期间。
