Efficacy and safety of extracorporeal shock wave therapy for orthopedic conditions: a systematic review on studies listed in the PEDro database

Background: Extracorporeal shock wave therapy (ESWT) is an effective and safe non-invasive treatment option for tendon and other pathologies of the musculoskeletal system. Sources of data:This systematic review used data derived from the Physiotherapy Evidence Database (PEDro; , 23 October 2015, date last accessed). Areas of agreement:ESWT is effective and safe. An optimum treatment protocol for ESWT appears to be three treatment sessions at 1-week intervals, with 2000 impulses per session and the highest energy flux density the patient can tolerate. Areas of controversy:The distinction between radial ESWT as 'low-energy ESWT' and focused ESWT as 'high-energy ESWT' is not correct and should be abandoned. Growing points:There is no scientific evidence in favour of either radial ESWT or focused ESWT with respect to treatment outcome. Areas timely for developing research:Future randomized controlled trials should primarily address systematic tests of the aforementioned optimum treatment protocol and direct comparisons between radial and focused ESWT.
