OBJECTIVE: To assess the efficacy of extracorporeal shockwave therapy (ESWT) and provide clinicians with an evidence base for their clinical decision making. DATA SOURCES: PubMed, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Evidence-Based Medicine Reviews. STUDY SELECTION: All randomized or quasi-randomized controlled trials of ESWT for chronic recalcitrant plantar fasciitis were searched. Searching identified 108 potentially relevant articles; of these, 7 studies with 550 participants met inclusion criteria. DATA EXTRACTION: Number of patients, population, body mass index, duration of symptoms, adverse effects, blinding method, and details of shockwave therapy were extracted. DATA SYNTHESIS: For intervention success rate, ESWT of low intensity was more effective than control treatment of low intensity. For pain relief, the pooled data showed a significant difference between the ESWT and control groups. For function, only low-intensity ESWT was significantly superior over the control treatment. CONCLUSIONS: The efficacy of low-intensity ESWT is worthy of recognition. The short-term pain relief and functional outcomes of this treatment are satisfactory. However, owing to the lack of a long-term follow-up, its long-term efficacy remains unknown.
