Učinek placeba pri terapiji s transkutano električno-živčno stimulacijo pri osebah s kronično bolečino v križu : pregled literature

Stojnić, Dejana (author), Rugelj, Darja (mentor)

Uvod: živimo v času, ko je bolečina v križu ena najpogostejših obolenj. Obstajajo različni načini obvladovanja tega stanja. Ena izmed njih je transkutana električno živčna stimulacija (TENS), kjer stimulacija živčnih vlaken Aα, Aβ in C vlaken vpliva na bolečino ter na subjektivno ali objektivno izboljšanje stanja. Doseženo izboljšanje stanja na račun snovi ali posega (placebo) brez terapevtske vrednosti se imenuje placebo učinek. Namen: na osnovi pregleda literature ugotoviti, kolikšen je placebo učinek pri terapiji s transkutano živčno-električno stimulacijo pri pacientih s kronično bolečino v križu. Metode dela: pregled objavljene strokovne in znanstvene literature na spletu ter knjižnih virov. Rezultati: vključenih je bilo 9 raziskav, kjer so pacienti s kronično bolečino v križu prejeli terapijo s TENS. Vse zajete raziskave so bile randomizirane kontrolirane. Raziskave so trajale od 2 do 12 tednov. Pred in po koncu terapevtskega programa so jakost bolečine ocenili z vidno analogno lestvico. Placebo učinek se je jasno pokazal v dveh izmed obravnavanih raziskav, kjer so zaključili, da je učinkovitost placeba enakovredna učinkovitosti transkutani električno živčni stimulaciji. Zaključki preostalih raziskav so pokazali, da je TENS ali druga oblika uporabljene aktivne terapije učinkovitejša od placeba, kajti placebo učinek je bil zanemarljiv. Razprava in zaključek: pregled raziskav kaže, da so mnenja o placebo učinku deljena. Obstajajo študije, ki dokazujejo, da je placebo učinek prisoten v tolikšni meri, da je njegovo delovanje enakovredno delovanju TENS; nasprotujejo pa jim tiste, katerih zaključki kažejo, da placebo nima enake terapevtske vrednosti kakor le ta. V prihodnje je potrebno opraviti nadaljnje raziskave, ki bi vprašanje o terapevtski učinkovitosti placeba razrešile.

• Title: Placebo effect at treatment with transcutaneous electrical nerve stimulation (TENS) in patients with chronic low back pain

Abstract

Introduction: We live in time when low back pain is one of the most common medical condictions. There are different ways of controlling this condiction, and one of them is use of Transcutaneous Electrical Nerve Stimulation (TENS), where stimulation of nerve fibres Aα, Aβ in C nerve fibres affects pain and subjective or objective improvement of condiction. Improvement of condiction, caused by substance or intervention without therapeutic value (placebo), is called placebo effect. Purpose: To establish amount of placebo effect in treatment with Transcutaneous Electrical Nerve Stimulation in patients with low back pain. Methodology: Overview of published technical and scientific literature online and book sources. Results: In all nine evaluated studies people with low back pain recieved active form of therapy (TENS) and placebo. Studies were randomized controlled and lasted from 2-12 weeks. Pain was evaluated by the visual analogue scale (VAS), before and after treatment programme. Placebo effect was clearly noticed in two of all studies, where it was concluded that placebo is as much effective as transcutaneous electrical nerve stimulation. Conclusions of other studies show that TENS or any other active form of used therapy is more effective than placebo, since findings of their studies show that placebo effect is neglibigle. Disccusion and conclusion: Overview of studies shows that opinion about placebo effect is discordant. There are studies which show that placebo is equivalent to TENS; still, there are others who show that placebo is not effective as TENS is. Further investigations are needed to answer the incomplete question about placebo treatment effect.
