Gudun tafiyar da jijiyoyin jiki

Saurin tafiyar da jijiyoyi (NCV) gwaji ne don ganin yadda saurin sakonnin lantarki ke tafiya ta jijiya. Ana yin wannan gwajin tare da ilimin kimiyyar lantarki (EMG) don tantance tsokoki don rashin dacewa.

Ana sanya facin facin da ake kira wayoyin ƙasa akan fata akan jijiyoyi a wurare daban-daban. Kowane faci yana ba da motsi mai sauƙi na lantarki. Wannan yana motsa jijiya.

Sakamakon wutar lantarki na jijiya yana ɗauke da ɗayan wayoyin. Ana amfani da tazara tsakanin wayoyi da lokacin da za'ayi wajan motsawar lantarki tsakanin wayoyin don auna saurin siginar jijiyoyin.

EMG shine rikodin daga allurar da aka sanya a cikin tsokoki. Ana yin wannan galibi a lokaci ɗaya da wannan gwajin.

Dole ne ku zauna a cikin zafin jiki na al'ada. Yin sanyi sosai ko kuma dumi yana canza tasirin jijiya kuma yana iya ba da sakamako na ƙarya.

Faɗa wa likitanka idan kana da zuciya ta yin amfani da zuciya ko kuma bugun zuciya. Ana buƙatar ɗaukar matakai na musamman kafin gwajin idan kuna da ɗayan waɗannan na'urori.

Karka sanya kayan shafe shafe, sunnare, turare, ko man shafawa a jikinka a ranar gwajin.

Motsawar na iya jin kamar bugun lantarki. Kuna iya jin rashin jin daɗi dangane da ƙarfin tasirin. Kada ku ji zafi idan an gama gwajin.

Sau da yawa, gwajin gwajin jijiyar yana biyo bayan electromyography (EMG). A wannan gwajin, ana sanya allura a cikin tsoka kuma an gaya muku ku yi aiki da tsokar. Wannan tsari na iya zama mara dadi yayin gwajin. Kuna iya jin ciwon tsoka ko rauni bayan gwaji a wurin da aka saka allurar.

Ana amfani da wannan gwajin don tantance lalacewar jijiya ko lalacewa. Ana iya amfani da gwajin wani lokacin don kimanta cututtukan jijiya ko tsoka, gami da:

• Ciwon kai
• Lambert-Eaton ciwo
• Yankin Myasthenia
• Ciwon ramin rami na carpal
• Ciwon rami na Tarsal
• Ciwon neuropathy
• Kararrawa mai kararrawa
• Guillain-Barré ciwo
• Brachial plexopathy

NCV yana da alaƙa da diamita na jijiya da kuma matakin myelination (kasancewar kwarin myelin akan axon) na jijiyar. Sabbin jarirai suna da kimar da ta kai rabin na manya. Valuesimar manya ana zuwa da shekaru 3 ko 4.

Lura: Tsarin jeri na al'ada na iya bambanta kaɗan tsakanin ɗakunan gwaje-gwaje daban-daban. Yi magana da mai baka kiwon lafiya game da ma'anar takamaiman sakamakon gwajin ka.

Mafi sau da yawa, sakamakon sakamako mara kyau shine saboda lalacewar jiji ko lalata, gami da:

• Axonopathy (lalacewa ga ɓangaren ɓangaren ƙwayar jijiya)
• Tsarin toshewa (an katange motsi a wani wuri tare da hanyar jijiya)
• Demyelination (lalacewa da asarar murfin mai mai kewaye da ƙwayar jijiyar)

Lalacewar jijiya ko lalacewa na iya zama saboda yanayi daban-daban, gami da:

• Neuropathy na giya
• Ciwon neuropathy
• Jijiyoyin jijiya (daga gazawar koda)
• Raunin rauni ga jijiya
• Guillain-Barré ciwo
• Ciwon ciki
• Ciwon ramin rami na carpal
• Brachial plexopathy
• Cutar Charcot-Marie-Hakori (gado)
• Kullum polyneuropathy mai kumburi
• Rashin jijiyoyin peroneal na yau da kullun
• Rarraba ƙwayar jijiyar jiki
• Rashin lafiyar jijiyoyin mata
• Friedreich ataxia
• Janar paresis
• Mononeuritis multiplex (masu yawa mononeuropathies)
• Amyloidosis na farko
• Rashin jijiya na radial
• Sciatic jijiya rashin aiki
• Amyloidosis na tsarin na biyu
• Sensorimotor polyneuropathy
• Rashin jijiyoyin Tibial
• Ciwan jijiyar Ulnar

Duk wani cututtukan jijiyoyin jiki na iya haifar da sakamako mara kyau. Lalacewa ga lakar kashin baya da kuma layin diski (ƙananan ƙwayoyin cuta) tare da matsawar jijiya na iya haifar da sakamako mara kyau.

Gwajin NCV ya nuna yanayin mafi kyawun ƙwayoyin jijiya. Sabili da haka, a wasu lokuta sakamakon na iya zama na al'ada, koda kuwa akwai lalacewar jijiya.
