Short-wave diathermy in patients with chronic low back pain: A systematic review

Abstract

The aim of this study was to evaluate the evidence of application of short-wave diathermy (SWD) in individuals with chronic low back pain (CLBP) and its prescription parameters. The data sources (MEDLINE, PubMed, LILACS, DARE, PsycINFO, AusportMed, SciELO, PEDro and the Cochrane Central Register of Controlled Trials) were systematically searched for articles published up to December 2017. Randomized and non-randomized clinical trial studies that investigated the effect of the application of SWD on CLBP were selected. Two independent reviewers assessed the risk of bias in studies using the Jadad and the Downs & Black scales. Five studies (731 patients) were included, all of whom presented improvements in CLBP. The majority used continuous mode SWD, with only one using pulsed mode (82 and 200 Hz). SWD produced improvements in CLBP, but there is limited evidence for its application, and a lack of standardization of the parameters used. Furthermore, the results that address this topic should be interpreted with caution due to their low methodological quality and limited number. Level of evidence II; Systematic review.
