Umbane wombane

I-Electromyography (EMG) luvavanyo olujonga impilo yezihlunu kunye neerval ezilawula izihlunu.

Umboneleli wezempilo ufaka inaliti ecekeceke kakhulu ye-electrode ngesikhumba esihlunwini. I-electrode yenaliti ithatha umsebenzi wombane owenziwe yimisipha yakho. Lo msebenzi uvela kwisohlo esikufutshane kwaye unokuviwa ngesithethi.

Emva kokubekwa kwee-electrode, unokucelwa ukuba usayine imisipha. Umzekelo, ngokugoba ingalo. Umsebenzi wombane obonwe ekubekeni esweni unika ulwazi malunga nokubanakho kwezihlunu zakho zokuphendula xa imithambo-luvo yemisipha yakho ivuselelwa.

Uvavanyo lwe-velocity velocity test luhlala lusenziwa ngexesha lotyelelo olunye njenge-EMG. Uvavanyo lwesantya lwenziwe ukubona ukuba isantya sombane sihamba njani na kwimithambo-luvo.

Akukho lungiselelo lukhethekileyo ludla ngokufuneka. Kuphephe ukusebenzisa naziphi na iikhrimu okanye into yokuthambisa ngomhla wovavanyo.

Ubushushu bomzimba bunokuchaphazela iziphumo zolu vavanyo. Ukuba kubanda kakhulu ngaphandle, unokuxelelwa ukuba ulinde kwigumbi elifudumeleyo okwethutyana ngaphambi kokuba kwenziwe uvavanyo.

Ukuba uthatha i-thinner yegazi okanye i-anticoagulants, yazisa umboneleli owenza uvavanyo ngaphambi kokuba lwenziwe.

Unokuziva ubuhlungu okanye ungonwabi xa kufakwa iinaliti. Kodwa uninzi lwabantu luyakwazi ukulugqiba uvavanyo ngaphandle kweengxaki.

Emva koko, umsipha unokuziva uthambile okanye utyumkile iintsuku ezimbalwa.

I-EMG ihlala isetyenziswa xa umntu eneempawu zobuthathaka, iintlungu, okanye iimvakalelo ezingaqhelekanga.Inokukunceda umahluko phakathi kobuthathaka bemisipha obangelwa kukwenzakala kwethambo eliqhotyoshelwe kwimisipha, kunye nobuthathaka ngenxa yokuphazamiseka kwenkqubo yemithambo-luvo, enjengezifo zemisipha.

Ngokwesiqhelo kukho umbane omncinci kakhulu kwimisipha ngelixa uphumle. Ukufaka iinaliti kunokubangela umsebenzi wombane, kodwa xa izihlunu zithe cwaka, kufanelekile ukuba kubekho umsebenzi ombane omncinci ofunyenweyo.

Xa uguqula umsipha, umsebenzi uqala ukuvela. Njengoko uthatha imisipha yakho ngakumbi, umsebenzi wombane uyanda kwaye ipatheni iyabonakala. Le patheni inceda ugqirha wakho ukuba abone ukuba umsipha uphendula ngendlela efanelekileyo.

I-EMG iyakwazi ukubona iingxaki ngezihlunu zakho ngexesha lokuphumla okanye lomsebenzi. Ukuphazamiseka okanye iimeko ezibangela iziphumo ezingaqhelekanga zibandakanya oku kulandelayo:

• Utywala lwe-neuropathy (ukonakalisa imithambo-luvo kukusela utywala kakhulu)
