To assess the efficacy of shear-wave elastography (SWE) of the plantar fascia (PF) in identifying plantar fasciitis.
A literature search was conducted on the PubMed and Medline databases for articles published up to August 2022. The Newcastle-Ottawa scale was used to assess the risk of bias. We included original research studies in English dealing with the evaluation of patients with plantar fasciitis by means of SWE and including shear modulus (KPa) and/or shear-wave velocity (m/s). We compared healthy and pathologic PF stiffness using the standardised mean difference (SMD) in a random-effects model (95% CI).
Five studies were included with a total of 158 pathologic PFs and 134 healthy PFs. No significant publication bias was detected. Studies were highly heterogeneous (p < 0.00001; I = 97%). Pathologic PFs showed significantly lower stiffness, with an SMD of - 3.00 m/s (95% confidence interval: - 4.95 to - 1.06, p = 0.002), compared to healthy PF.
Pathologic PFs present significantly lower stiffness than healthy PFs. However, the analysed studies are highly heterogeneous.
评估足底筋膜（PF）剪切波弹性成像（SWE）在诊断足底筋膜炎中的效果。
在 PubMed 和 Medline 数据库中对截至 2022 年 8 月的文献进行检索。使用纽卡斯尔-渥太华量表评估偏倚风险。我们纳入了以 SWE 评估足底筋膜炎患者的原始研究，并纳入了剪切模量（kPa）和/或剪切波速度（m/s）。我们使用随机效应模型（95%CI）比较了健康和病理 PF 的刚度，使用标准化均数差值（SMD）进行比较。
共纳入 5 项研究，共计 158 例病理 PF 和 134 例健康 PF。未发现明显的发表偏倚。研究之间存在高度异质性（p<0.00001；I=97%）。与健康 PF 相比，病理 PF 的刚度明显降低，SMD 为-3.00 m/s（95%置信区间：-4.95 至-1.06，p=0.002）。
病理 PF 的刚度明显低于健康 PF。然而，分析的研究存在高度异质性。
