The Efficacy of Extracorporeal Shock Wave Therapy as a Monotherapy for Achilles Tendinopathy: A Systematic Review and Meta-Analysis
Abstrakt
The aim of this systematic review and meta-analysis was to determine the therapeutic efficacy of extracorporeal shock wave therapy (ESWT) for Achilles tendinopathy.
We searched PubMed, EBSCOHost, Ovid, and Embase for randomized controlled trials. Databases were searched from their inception until the last entry (July 16, 2022). The methodological quality of the randomized controlled trials was rated with the Physiotherapy Evidence Database scale. For continuous data, we presented the mean difference (D) and 95% confidence interval (CI). Heterogeneity was assessed with I2 statistics. The random effects model was applied for the pooled effect estimates. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation tool.
The very-low-quality evidence suggested that ESWT was no more effective in decreasing pain than any other conservative treatment (D: -0.8; 95% CI: -3.15, 1.56; P > .5; I2 = 85.62%). No significant differences were found between the ESWT and control groups on the pooled Victorian Institute of Sport Assessment-Achilles scores (D: 5.74; 95% CI: -15.02, 26.51; P = .58; I2 = 92.28%), but the quality of evidence was very low.
At present, the quality of the evidence is low; thus, the therapeutic efficacy of ESWT for Achilles tendinopathy is inconclusive.
