Funda ngemithambo-luvo kunye nezihlunu zakho ngovavanyo lwe-EMG (Electromyography)! Singathetha ngale nto?

Ngaba ngamanye amaxesha uziva ungenamandla emilenzeni yakho? Okanye uziva ubuthathaka okanye iintlungu kwimisipha yakho? Mhlawumbi ugqirha wakho ukuxelele ngovavanyo lwe-EMG (Electromyography) . Unemibuzo emininzi malunga nokuba yintoni le EMG, kutheni yenziwa, kwaye yenziwa njani, akunjalo? Ungakhathazeki, namhlanje siza kuthetha ngayo yonke into ngokulula, ngendlela onokuyiqonda.

Yintoni i-EMG (i-Electromyography)?

Ngamafutshane, i-EMG (i-Electromyography) luvavanyo olukhethekileyo olujonga impilo kunye nokusebenza kwemisipha yakho yamathambo - izihlunu esizilawulayo ngabom (njengezo sizisebenzisa ukuhambisa iingalo zethu nokuhamba) - kunye nemithambo-luvo elawula ezo zihlunu. Olu luhlobo lovavanyo lwe -electrodiagnostic .

Yonke intshukumo esiyenzayo, njengokuphakamisa umlenze okanye ukushukumisa intloko yethu, ibangelwa kukunxibelelana okuntsonkothileyo phakathi kwenkqubo yakho yemithambo-luvo (ingqondo kunye nomqolo) , iimithambo-luvo, kunye nezihlunu. Ukuze kuveliswe intshukumo, iimithambo-luvo zakho zemithambo-luvo , iimithambo-luvo ezilawula intshukumo, zithumela imiqondiso yombane kwimisipha yakho. Uvavanyo lwe-EMG lunokufumanisa iingxaki ngezi mithambo-luvo zemithambo-luvo, izihlunu, okanye unxibelelwano phakathi kwezi zimbini.

Iingcali ze-neurologists zihlala zenza uvavanyo lwe-EMG kunye ne -Nerve Conduction Study (NCS) . I-NCS ilinganisa isantya kunye nobungakanani beempawu zombane ezihamba kwi-nerve. I-EMG ilinganisa indlela imisipha esabela ngayo kuloo msebenzi wombane kunye nokuba ingakanani imisebenzi yombane eyenziwayo xa imisipha ifinyela.

Ukuba uneempawu ezifana nobuthathaka bemisipha, ukungakhululeki, okanye ukurhawuzelela, ugqirha wakho unokucebisa i-EMG. Olu luvavanyo oluhlala lwenziwa kwindawo yokulaliswa esibhedlele, kodwa ngamanye amaxesha lunokwenziwa ngelixa usesibhedlele.

Yintoni enokufunyanwa kuvavanyo lwe-EMG?

Uvavanyo lwe-EMG lunokunceda ekuchongeni inani leengxaki ezahlukeneyo kunye neemeko ezichaphazela imithambo-luvo yakho kunye nemisipha . Lunokufumanisa nokuba ezi ngxaki zisasazeke kangakanani kwaye ziphi na. Ngamanye amaxesha, olu vavanyo lukwasetyenziselwa ukuthintela imeko ethile.

Nazi ezinye zeemeko ezinokunceda ekuxilongweni kovavanyo lwe-EMG:

• Iingxaki ezichaphazela imithambo-luvo engaphandle: Umzekelo , iimeko zokucinezelwa kwemithambo-luvo ezifana ne-peripheral neuropathy kunye ne-carpal tunnel syndrome .
• Iingxaki ezichaphazela iingcambu zemithambo-luvo eziphuma kwintambo yomqolo: umzekelo, imithambo-luvo ecinezelekileyo, i-cervical radiculopathy , okanye i-sciatica .
• Iingxaki zemisipha (i-myopathies): Imizekelo ibandakanya i-muscular dystrophy , i-polymyositis , kunye ne -dermatomyositis .
• Iimeko ezichaphazela ii-motor neurons kwingqondo okanye kwi-spinal cord: umzekelo , i-amyotrophic lateral sclerosis (ALS) okanye i-post-polio syndrome .
• Iimeko ezichaphazela unxibelelwano phakathi kwemithambo-luvo kunye nemisipha: umzekelo , i-myasthenia gravis .

Khumbula, uvavanyo lwe-EMG aluyondlela yodwa yokuxilonga ezi meko. Oogqirha basebenzisa uvavanyo lwemifanekiso, olufana ne-X-ray, i-CT scans, i-MRI scans, uvavanyo lwegazi , kwaye ngamanye amaxesha i-muscle biopsies.

Uvavanyo lwe-EMG lusebenza njani?

Ukuze siqonde indlela esebenza ngayo i-EMG test, masiqale sijonge indlela esebenza ngayo imisipha yethu.

Ii-neuron zakho ze-motor zithumela imiqondiso yombane kwimisipha yakho, zixelela ukuba zenze ntoni. (Ezi miqondiso ziqala engqondweni yakho, emva koko zihambe ngentambo yomqolo wakho, ngee-neuron ze-motor, ziye kwimisipha yakho.) Olu vuselelo lombane lubangela ukuba imisipha iqine (iqine). Xa imisipha iqina, nomsebenzi wombane nawo uyaveliswa.

Ngokwesiqhelo, umsipha ophumlileyo awunamsebenzi wombane. Ukuba umsipha uncipha kancinci, kwenzeka umsebenzi othile wombane, kwaye xa uncipha kakhulu, uyanda nangakumbi.

Kuvavanyo lwe-EMG, ugqirha okanye ingcali eqeqeshiweyo ifaka inaliti ecolekileyo kakhulu (i-electrode yenaliti) kwenye yezihlunu zakho. I-electrode ekule naliti irekhoda umsebenzi wombane wezihlunu. Inaliti ayithumeli mbane emzimbeni wakho. Ifana nemakrofoni, irekhoda kuphela.

I-electrode yenaliti irekhoda umsebenzi wombane xa ubambe umsipha ungashukumi kwaye xa uwufinyeza. Le naliti iqhagamshelwe kwikhompyutha ngentambo. Ugqirha angabona kwiscreen okwenzekayo xa umsipha wakho ungashukumi kwaye xa uwushukumisa. Oku kubonakala njengamaza kwiscreen. Ngamanye amaxesha unokuva nee-pulses zalo msebenzi wombane usebenzisa i-audio amplifier.

Ugqirha emva koko uhlalutya ezi zibalo ukuze abone ukuba kukho naziphi na iimpawu zengxaki. Umzekelo, ukuba esinye sezihlunu zakho sonakele, sinokubonisa umsebenzi ongaqhelekanga wombane xa siphumle. Kwakhona, xa sincipha, umsebenzi wombane ungabonisa iipatheni zamaza ezingaqhelekanga.

Ungayilungiselela njani uvavanyo lwe-EMG?

Ngaphambi kovavanyo lwe-EMG, kufuneka wenze oku kulandelayo:

• Yiza uhlambe, ucocekile, kwaye unxibe impahla ekhululekileyo nekhululekileyo.
• Musa ukuthambisa naziphi na iikhrimu , iiloshini, okanye iziqholo eluswini. Iikhrimu kunye neeloshini zinokuchaphazela ukuchaneka kovavanyo.
• Ukuba uthatha amayeza okuthintela ukopha kwegazi (afana ne-warfarin), qiniseka ukuba uxelele ugqirha ukuba ngubani owenza uvavanyo lwe-EMG. Izinto zokunciphisa igazi zinokunyusa kancinci umngcipheko wokopha emva kwe-EMG. Nangona kunjalo, ungayeki ukuzithatha ngaphandle kokuthetha nogqirha owakunike umyalelo.
• Sixelele nokuba ufake i-pacemaker okanye esinye isixhobo sezonyango se-elektroniki.

Kwezinye iimeko, ugqirha wakho unokukuxelela ukuba ungatshayi icuba okanye usele iziselo ezine-caffeine , ezifana nekofu okanye iti, kangangeeyure ezimbini ukuya kwezintathu ngaphambi kovavanyo. Ezi zinto zinokuphazamisa uvavanyo.

Kwenzeka ntoni ngexesha lovavanyo lwe-EMG?

Iingcali ze-neurologists zihlala zenza uvavanyo lwe-EMG emva kokwenza uphando lwe-nerve conduction (NCS). Kwi-NCS, ugqirha ubeka ii-electrodes (ezifana nezitikha) eluswini lwakho. Emva koko, ugqirha ufaka into evakala ngathi kukuthuthumela okuncinci kombane kwimithambo-luvo aze abhale impendulo. Rhoqo, imithambo-luvo emininzi iyavavanywa ngale ndlela.

Indlela eyenziwa ngayo uvavanyo lwe-EMG inokwahluka kancinci, kuxhomekeke kwisizathu sovavanyo kunye nemisipha kunye nemithambo-luvo evavanywayo. Kodwa ngokubanzi ungalindela into efana nale:

• Uza kuxelelwa ukuba uhlale phantsi okanye ulale phantsi.
• Ugqirha ukhetha izihlunu afuna ukuzihlola.
• Emva koko, kufakwa ii-electrode ezincinci kakhulu zenaliti ngesikhumba sakho kwimisipha. Ezi naliti zihlala kwimisipha malunga nomzuzu okanye emibini. Ungaziva ungakhululekanga okanye uneentlungu xa kufakwa iinaliti.
• Ugqirha uza kukuxelela ukuba uphumze izihlunu, uze uzisebenzise ngeendlela ezithile, njengokuphakamisa okanye ukugoba ingalo okanye umlenze.
• Umatshini ulinganisa umsebenzi wombane wezihlunu zakho ezisebenzayo aze awubonise kwiscreen. Wenzelwe ukuvelisa isandi.
• Emva kokuba idatha eyaneleyo ibhaliwe kwisihlunu, inaliti iyasuswa.
• Umsipha olandelayo uvavanywa ngale ndlela de uvavanyo lugqitywe.

Ngaba uvavanyo lwe-EMG lubuhlungu?

Usenokuziva iintlungu okanye ukungakhululeki xa inaliti ifakwa eluswini nakwimisipha.Uninzi lwabantu lunokuphumelela olu vavanyo ngaphandle kweengxaki.

Emva kovavanyo, izihlunu ezivavanyiweyo zisenokuba buhlungu kancinci kangangeentsuku ezimbalwa.

Uvavanyo lwe-EMG luthatha ixesha elingakanani?

Olu vavanyo ludla ngokuthatha imizuzu engama-60 ukuya kwengama-90 , kuxhomekeke ekubeni ugqirha wakho ufuna ukuvavanya izihlunu ezingakanani.

Yintoni onokuyilindela emva kovavanyo lwe-EMG?

Izihlunu zakho zingavakala zibuhlungu okanye ziqinile kangangeentsuku ezimbalwa emva kovavanyo. Olu buhlungu bezihlunu aludli ngokuba buhlungu kakhulu kwaye kufuneka luphele kwisithuba seveki. Ungabona nemivumbo emincinci apho iinaliti zifakwe khona.

Zithini iingozi zovavanyo lwe-EMG?

I-EMG ngokuqhelekileyo luvavanyo olukhuselekileyo. Iingxaki azixhaphakanga. Abanye abantu (ingakumbi abo bathatha amayeza okunciphisa igazi ) banokufumana ukopha emva kovavanyo.

Zithini iziphumo zovavanyo lwe-EMG?

Nangona uvavanyo lwe-EMG luluncedo kakhulu, alusoloko lubonelela ngoxilongo ngokwalo. Iqela lakho lezonyango liza kudibanisa ezi ziphumo kunye neziphumo zezinye iimvavanyo zonyango ukuze kuchongwe uxilongo.

Kuthatha ixesha elingakanani ukwazi iziphumo?

Ngokwesiqhelo uza kufumana iziphumo zakho kwiiyure ezingama-24 ukuya kwezingama-48 emva kokuba uvavanyo lugqityiwe.

Ndingamxelela nini ugqirha wam nge-EMG yam?

Fowunela ugqirha wakho ukuba oku kuyenzeka:

• Ukuba ukopha akupheli.
• Ukuba kukho intlungu okanye ukuqina okukhulu apho iinaliti zifakwe khona.
