The outcomes of corticosteroid injection (CSI) and extracorporeal shock wave therapy (ESWT) as primary treatment of plantar fasciitis have been debated. This study was conducted to compare and evaluate the therapeutic effects of ultrasound-guided CSI versus medium frequency ESWT in the treatment of plantar fasciitis among Chinese population.
This study was a single-center, randomized, and double-blinded trial. The study protocol was approved by local ethics committee board and subsequently registered in Research Registry. Eighty patients with unilateral plantar fasciitis were randomized to receive either ESWT (3 times once per week) (n = 40) or CSI treatment (a single 1-mL dose of betamethasone sodium plus 0.5 mL of prilocaine under ultrasound guidance by injection into the plantar fascia) (n = 40). The primary outcome measures were visual analog scale and Foot Function Index scores. Secondary outcome measures included the heel tenderness index score and plantar fascia thickness as obtained by ultrasound examination. All of the assessments were performed at baseline and 1, 3, and 6 months after treatment.
This is a randomized controlled trial evaluating the efficacy of CSI versus ESWT in the treatment of plantar fasciitis. This study has limited inclusion and exclusion criteria and a well-controlled intervention.
The results of this trial will provide more evidence on which method can better treat plantar fasciitis.
This study protocol was registered in Research Registry (researchregistry5428).
皮质类固醇注射（CSI）和体外冲击波疗法（ESWT）作为足底筋膜炎的主要治疗方法，其疗效一直存在争议。本研究旨在比较和评估超声引导下的CSI与中频ESWT在中国人群中治疗足底筋膜炎的疗效。
本研究为单中心、随机、双盲试验。研究方案经当地伦理委员会批准，随后在研究注册中心注册。80名单侧足底筋膜炎患者被随机分为接受ESWT组（每周1次，共3次）（n = 40）或CSI治疗组（在超声引导下向足底筋膜注射1 mL倍他米松钠加0.5 mL丙胺卡因）（n = 40）。主要观察指标为视觉模拟评分和足部功能指数评分。次要观察指标包括足跟压痛指数评分和超声检查获得的足底筋膜厚度。所有评估均在基线时以及治疗后1、3和6个月进行。
这是一项评估CSI与ESWT治疗足底筋膜炎疗效的随机对照试验。本研究的纳入和排除标准有限，干预措施控制良好。
本试验结果将为哪种方法能更好地治疗足底筋膜炎提供更多证据。
本研究方案已在研究注册中心注册（researchregistry5428）。
