Electromyography (EMG)

I-electromyography (EMG) iyinqubo yokuxilonga ukuhlola impilo yemisipha namalunga ezinzwa awalawo misipha (ama-motor neurons). Imiphumela ye-EMG ingabonisa ukungasebenzi kahle kwezinzwa, ukungasebenzi kahle kwemisipha noma izinkinga zokudluliswa komyalezo phakathi kwezinzwa nemisipha. Ama-motor neurons adlulisela izimpawu zombane ezenza imisipha iqhubeke. I-EMG isebenzisa amadivayisi amancane okuthiwa ama-electrodes ukuhumusha lezi zimpawu zibe imigqa, imisindo noma amanani ebalwa bese kuqondwa ochwepheshe.

Udokotela wakho angase ayekelele i-EMG uma unezimpawu noma izimpawu ezingase zibonise ukuthi une-nerve noma isifo samathambo. Izimpawu ezinjalo zingafaka: Ukukhahlela Ukungezwani Ubuthakathaka bemisipha Ubuhlungu bemisipha noma ukubamba Izinhlobo ezithile zobuhlungu lwezinye zezimbangi Imiphumela ye-EMG ivame ukudingeka ukusiza ekuthola noma ukuphika izimo eziningi ezinjengalezi: Izifo zamisipha, njengokuwohloka kwemisipha noma i-polymyositis Izifo ezihlasela ukuxhumana phakathi kwe-nerve nemisipha, njenge-myasthenia gravis Izifo zezinzwa ngaphandle komgogodla (izinzwa ezingaphandle), njenge-carpal tunnel syndrome noma i-peripheral neuropathies Izifo ezihlasela ama-motor neurons ebuchosheni noma emgogodleni, njenge-amyotrophic lateral sclerosis noma i-polio Izifo ezihlasela impande yethambo, njengendwangu ephukile emgogodleni

I-EMG yindlela yokwelapha engenayo ingozi enkulu, futhi izinkinga zingezinkulu. Kukhona ingozi encane yokopha, ukutheleleka nokulimala kwama-nerve lapho kufakwa khona i-electrode yesihlanzi. Uma imisipha eceleni lodonga lwesibeletho ihlolwa nge-electrode yesihlanzi, kunethuba elincane kakhulu lokuthi ingabangela umoya ukuthi ugeleze endaweni phakathi kwamaphaphu nodonga lwesibeletho, okubangela ukuthi iphunga liwe (pneumothorax).
