Transcutaneous Electrical Nerve Stimulation (TENS) for Pain Management During Labor.
Recruiting now · Not applicable · Has a placebo group
Conditions studied: Labor Pain
In brief
This is a randomized, double-blind, crossover clinical trial to evaluate the efficacy of transcutaneous electrical nerve stimulation (TENS) as a non-pharmacological therapeutic intervention for reducing pain in women during the active phase of labor. Nulliparous women with term pregnancies will be randomly assigned to sequences involving TENS intervention and placebo (device off) periods, separated by a washout. The primary outcome is labor pain intensity measured by the Visual Analog Scale (VAS). Secondary outcomes include duration of the active labor phase, maternal and neonatal safety profile, and childbirth experience satisfaction. The study will be conducted at the Hospital Escuela Universitario from feb 2026 to Ago 2026.
