Transcutaneous Electric Nerve Stimulation Reduces Acute Postoperative Pain and Analgesic Use After Open Inguinal Hernia Surgery: A Randomized, Double-Blind, Placebo-Controlled Trial

In this randomized, double-blind, placebo-controlled trial, we evaluated the role of transcutaneous electrical nerve stimulation (TENS) in multimodal treatment (nonopioid analgesics and kinesiotherapy) postoperative pain following open inguinal hernia repair.In total, 80 males participants with elective primary unilateral Lichtenstein repair were randomly allocated to receive TENS or a placebo-TENS procedure. The group received local segmental conventional on first second days. group, intensity was set at 0 0.5mA.
