Electroacupuncture did not significantly reduce the pain scores in individuals with chronic low back pain (CLBP) but it resulted in statistically and clinically greater reduction in back pain-specific disability compared with placebo (sham electroacupuncture treatment).
Why this matters
Current evidence shows similar effects of manual acupuncture and placebo on CLBP but studies evaluating electroacupuncture in CLBP are limited.
Identifying factors associated with clinical response to electroacupuncture is important for triaging and implementation of acupuncture.
According to the authors, this is the first randomized controlled trial to demonstrate statistically and clinically significant effect of electroacupuncture on back pain-specific disability.
