초록

Purpose: The purpose of this study is to assess the effectiveness of short-wave therapy (SWT) for treatment of kneeosteoarthritis (OA) as compared to placebo and control, and to assess the question of whether the effects are related to themode, dosage, and application method.
Methods: We searched randomized, placebo-controlled trials using electronic databases. We also manually reviewed sources inorder to identify additional relevant studies.
Results: Eight studies (597 participants) with OA were included in the meta-analysis. Pulse SWT had a significant effect on painrelief compared with control treatment, while did not favour compared with the placebo group. Pulse SWT had a significanteffect on functional improvement compared with control and placebo treatment. Continuous SWT had no effect on pain reliefand functional improvement. Capacitive SWT a significant effect on pain relief, functional improvement, and muscle strength.
Continuous and capacitive SWT had increased muscle strength significantly. We found no clinical significance of all outcomesexcept pain and functional improvement in pulsed SWT with low dose. There was no difference in adverse events. None of theparticipants experienced any serious adverse events.
Conclusion: Low dose pulsed SWT provided a short-term clinical benefit for pain relief and functional improvement. Pulsed SWDwith low and high dose had effects on pain and function. There seems to be a placebo effect. We found significant effects onpain and function in capacitive SWT. Despite some positive findings, this analysis lacked data on how effectiveness is affectedby mode, dosage, and application method of SWT. Further well-designed clinical studies are required in order to confirm theeffectiveness of SWT.
