The aim of this study was to investigate effectiveness of electroacupuncture (EA) and manual acupuncture (MA) on pain and disability in patients with chronic low back.
A total of 66 randomly allocated patients diagnosed with chronic LBP were assigned to receive either 12 sessions of acupuncture or electr LINK Word.Document.12 D:MYFILESELSEVIERJAMS00000470PREPTUDJAMS_470_tud.docx OLE_LINK1 a r Sao Paulooacupuncture. The primary outcomes measurements were intensity pain (NRS) and disability (RMQ). All main analysis followed the intention-to-treat principle.
The groups reported improvements posttreatment in intensity pain and disability respectively; however, no differences between groups were observed. Regarding the secondary outcomes, we observed a between-group difference only for kinesiophobia in favor of the manual acupuncture group (difference = −4.1 points, 95% CI = −7.0 to −1.1). The results were maintained after 3 months of follow-up. Contrary to our hypothesis, however, EA did not result in a better outcome compared with MA treatment.
The study does not provide evidence that an electroacupuncture is superior to acupuncture treatment. Both therapies had similar efficacy in reducing pain and disability for chronic nonspecific low back pain.
