Systematic review finds shockwave therapy offers no consistent benefit for Achilles tendinopathy compared to controls
This systematic review with meta-analysis examines the efficacy of shockwave therapy for insertional and midportion Achilles tendinopathy in adults. The review included 557 participants and compared radial or focused SWT with or without co-interventions against sham-SWT, no treatment, or wait-and-see controls. Follow-up assessments covered short- and long-term outcomes.
The analysis found no clinically meaningful benefit over sham for insertional Achilles tendinopathy. For midportion Achilles tendinopathy, there were no significant differences in disability or pain between SWT and control interventions at all timepoints. However, one trial did report a benefit over sham-SWT for midportion cases. The evidence for radial SWT in midportion cases showed very low-certainty evidence of a clinically meaningful effect on improvements in disability and pain compared to sham or wait-and-see controls.
Safety concerns were noted as two Achilles tendon ruptures were reported following focused SWT. Most effect estimates are based on very low- and low-certainty data. One trial did not report success of participant blinding. The authors state that true effects may change with future high-quality trials.
The review concludes that SWT should not be considered a routine treatment for either insertional or midportion Achilles tendinopathy, and alternative treatments should be prioritized.
