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

ABSTRACT

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; www.pedro.org.au, 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.
