Transcutaneous Electrical Nerve Stimulation (TENS) ua haujlwm ntawm cov hauv paus ntsiab lus ntawm kev kho mob los ntawm ob qho tib si peripheral thiab central mechanisms. Los ntawm kev xa cov hluav taws xob tsis tshua muaj hluav taws xob los ntawm cov hluav taws xob tso rau ntawm daim tawv nqaij, TENS activates loj myelinated A-beta fibers, uas inhibit qhov kis ntawm nociceptive signals los ntawm dorsal horn ntawm tus txha caj qaum, ib tug tshwm sim piav los ntawm lub rooj vag tswj txoj kev xav.
Tsis tas li ntawd, TENS tuaj yeem ua rau muaj kev tso tawm ntawm cov tshuaj endogenous opioids, xws li endorphins thiab enkephalins, uas ntxiv txo qhov kev xav ntawm qhov mob los ntawm kev khi rau opioid receptors nyob rau hauv nruab nrab thiab peripheral paj hlwb. Cov teebmeem analgesic tam sim tuaj yeem tshwm sim li ntawm 10 mus rau 30 feeb tom qab pib ntawm stimulation.
Quantitatively, kev sim tshuaj ntsuam xyuas tau pom tias TENS tuaj yeem ua rau txo qis ntawm VAS cov qhab nia, feem ntau ntawm 4 thiab 6 cov ntsiab lus, txawm hais tias kev hloov pauv nyob ntawm tus neeg mob qhov pib, qhov mob tshwj xeeb raug kho, qhov chaw electrode, thiab qhov tsis muaj kev txhawb siab (xws li, zaus thiab siv zog). Qee qhov kev tshawb fawb qhia tias cov zaus ntau dua (piv txwv li, 80-100 Hz) yuav ua tau zoo dua rau kev tswj qhov mob, qhov qis dua (piv txwv li, 1-10 Hz) tuaj yeem muab cov teebmeem ntev dua.
Zuag qhia tag nrho, TENS sawv cev rau kev kho mob uas tsis muaj kev cuam tshuam hauv kev tswj kev mob hnyav, muab cov txiaj ntsig zoo-rau-kev pheej hmoo piv thaum txo qis kev cia siab rau cov tshuaj siv tshuaj.
