I-Transcutaneous Electrical Nerve Stimulation (TENS) isebenza ngezimiso zokuguquguquka kobuhlungu ngokusebenzisa kokubili izindlela ezizungezile nezimaphakathi. Ngokuletha ama-voltage aphansi kagesi ngokusebenzisa ama-electrode abekwe esikhumbeni, i-TENS ivuselela ama-myelinated A-beta fibers amakhulu, avimbela ukudluliswa kwezibonakaliso ze-nociceptive ngokusebenzisa uphondo lwe-dorsal yomgogodla, into echazwe yi-theory yokulawula isango.
Ngaphezu kwalokho, i-TENS ingase ibangele ukukhululwa kwama-opioid angapheli, njengama-endorphin nama-enkephalins, aqhubeka enciphisa ukuqonda kobuhlungu ngokubophezela kuma-opioid receptors kuzo zombili izinhlelo zezinzwa eziphakathi nendawo. Imiphumela esheshayo ye-analgesic ingabonakala phakathi kwemizuzu eyi-10 kuya kwengama-30 ngemuva kokuqala kokuvuselela.
Ngokwesilinganiso, ukuhlolwa kwemitholampilo kubonise ukuthi i-TENS ingaholela ekunciphiseni okuphawulekayo kwezibalo ze-VAS izikolo, ngokuvamile phakathi kwe-4 ne-6 amaphuzu, nakuba ukuhlukahluka kuncike emikhawulweni yobuhlungu bomuntu ngamunye, isimo esithile sobuhlungu esiphathwayo, ukubekwa kwe-electrode, kanye nemingcele yokuvuselela (isb, imvamisa nokuqina). Ezinye izifundo ziphakamisa ukuthi ama-frequencies aphezulu (isb., 80-100 Hz) angase aphumelele kakhulu ekulawulweni kobuhlungu obukhulu, kanti ama-frequencies aphansi (isb., 1-10 Hz) angase anikeze imiphumela ehlala isikhathi eside.
Sekukonke, i-TENS imelela ukwelapha okungeziwe okungahlaseli ekulawuleni ubuhlungu obukhulu, enikeza isilinganiso esihle senzuzo-kuya-engozini kuyilapho inciphisa ukuthembela ekungeneleleni kwemithi.
