I-Transcutaneous Electrical Nerve Stimulation (TENS) isebenza ngokwemigaqo yokuguqulwa kwentlungu ngeendlela zombini ezisemacaleni naphakathi. Ngokuhambisa ii-empulses zombane ezine-voltage ephantsi ngee-electrodes ezibekwe eluswini, i-TENS isebenzisa ii-fibers ezinkulu ze-myelinated A-beta, ezithintela ukudluliselwa kwemiqondiso ye-nociceptive nge-dorsal horn ye-spinal cord, into echazwe yi-gate control theory.
Ngaphezu koko, i-TENS inokubangela ukukhululwa kwee-opioids zendalo, ezifana nee-endorphins kunye nee-enkephalins, ezinciphisa ngakumbi ukuqonda intlungu ngokuzibophelela kwii-receptors ze-opioid kwiinkqubo zemithambo-luvo eziphambili neze-peripheral. Iziphumo zokuthomalalisa ngokukhawuleza zinokubonakala kwimizuzu eli-10 ukuya kwengama-30 emva kokuqaliswa kokuvuselela.
Ngokwezibalo, uvavanyo lweklinikhi lubonise ukuba i-TENS inokukhokelela ekunciphiseni okubalulekileyo kwamanqaku e-VAS, ngokuqhelekileyo phakathi kwamanqaku ama-4 nama-6, nangona umahluko uxhomekeke kwimida yentlungu yomntu ngamnye, imeko ethile yentlungu enyangwayo, indawo ebekwe kuyo i-electrode, kunye nemilinganiselo yokukhuthaza (umz., imvamisa kunye nobunzulu). Ezinye izifundo zibonisa ukuba imvamisa ephezulu (umz., i-80-100 Hz) inokuba luncedo ngakumbi ekulawuleni iintlungu ezibukhali, ngelixa imvamisa ephantsi (umz., i-1-10 Hz) inokubonelela ngemiphumo ehlala ixesha elide.
Ngokubanzi, i-TENS imele unyango olungenalo ukungenelela ekulawuleni iintlungu ezibukhali, olubonelela ngomlinganiselo olungileyo wenzuzo-umngcipheko ngelixa lunciphisa ukuxhomekeka kwiindlela zonyango lwezonyango.
