Qalabku waa laba-cirifood.Laba electrodes oo ku yaal caarada.Marka koronto-dhaliyaha soo noqnoqda sare uu soo saaro mawjada hadda jirta, socodka hadda socda wuxuu u dhexeeyaa laba electrodes, kaas oo si toos ah ugu shaqeeya jidhka bini'aadamka, laba electrodes ayaa loo isticmaalaa sidii loop.Marka la shaqeeyo, oo leh awoodda koronto-dhaliye, caarada qalabku waxay ilaalisaa cadaadiska ugu fiican ee isku-dhafka unugyada.Soo saarista koronto ku habboon iyadoo loo eegayo jawaab celinta impedance ee kala duwan ee unugyada si toos ah u ogaan.Borotiinka collagen ee unugga bini'aadamka iyo cambaareynta borotiinka fibroeska ah, darbiga xididdada dhiigga ee samaynaya aag hufan, waxay soo saaraan xidhid joogto ah.
gogosha gacanta, caarada, rotator wheel, usheeda dhexe, daab, wiish goynta iyo badhanka kantaroolka, fiilada soo noqnoqda sare leh, silig xinjirowga laba-cirifoodka.
oo ka samaysan bir, caag, iyo dhoobo.
Tan iyo markii la aasaasay, warshadeena waxay horumarinaysay wax soo saarka heerka koowaad ee adduunka iyadoo la raacayo mabda'a
marka hore tayada leh.Badeecadahayadu waxay heleen sumcad aad u wanaagsan warshadaha iyo kalsoonida qiimaha leh ee macaamiisha cusub iyo kuwii hore.
