    BackgroundPlantar fasciitis (PF) is the most common reason for heel pain. The efficacy of extracorporeal shock wave therapy (ESWT) as an ideal alternative to conservative treatments and surgery is controversial, and almost all previous articles compared general ESWT with placebo without indicating the kind of shock wave. We undertook a meta-analysis to compare the efficacy of general ESWT, focused shock wave (FSW), and radial shock wave (RSW) with placebo, to assess their effectiveness in chronic PF.MethodsThe PubMed, Medline, EmBase, Web of Science, and Cochrane library databases were searched for studies comparing FSW or RSW therapy with placebo in chronic PF. Clinical outcomes included the odds ratios (ORs) of pain relief, pain reduction, and complications. Relevant data were analyzed using RevMan v5.3.ResultsNine studies involving 935 patients were included. ESWT had higher improvement rates than the placebo group (OR 2.58, 95% confidence interval [CI] 1.97-3.39, P < .00001). ESWT had markedly lower standardized mean difference than placebo, with heterogeneity observed (standardized mean difference 1.01, 95% CI -0.01 to 2.03, P = .05, I = 96%, P < .00001). FSW and RSW therapies had greater therapeutic success in pain relief than the placebo group (OR 2.17, 95% CI 1.49-3.16, P < .0001; OR 4.63, 95% CI 1.30-16.46, P = .02), but significant heterogeneity was observed in RSW therapy versus placebo (I = 81%, P = .005).ConclusionThis meta-analysis suggested that FSW therapy can relieve pain in chronic PF as an ideal alternative option; meanwhile, no firm conclusions of general ESWT and RSW effectiveness can be drawn. Due to variations in the included studies, additional trials are needed to validate these conclusions.
