Saosaoa conduction saoasaoa

O le saoasaoa o le avega o le uaua (NCV) o se tofotofoga e iloa ai le vave ona alu o faailo eletise i totonu o neula. O lenei suʻega e faia faʻatasi ma le electromyography (EMG) e iloilo ai maso mo faʻaletonu.

Adhesive patch ua taʻua o luga electrodes o loʻo tuʻuina i luga o le paʻu i neura i nofoaga eseese. Taitasi fugalaʻau aumaia ese se matua filemu lagona faʻaosofia. Lenei faʻaosofia ai neura.

O le iʻuga eletise gaioiga o neula ua faʻamaumauina e isi electrodes. O le mamao i le va o electrodes ma le taimi e alu ai mo eletise faʻaosofia e faimalaga i le va o electrodes e faʻaaogaina e fua ai le saoasaoa o neula faailo.

EMG o le puʻeina mai nila nila tuʻu i maso. E masani ona faia lea ile taimi e tasi ile suʻega lea.

E tatau ona e nofo i le masani ai le vevela o le tino. O le maalili tele poʻo le mafanafana tele e suia ai le faʻataʻitaʻi o neula ma mafai ai ona maua ai ni faʻaiuga sese.

Taʻu i lau fomaʻi pe a fai e iai sau fulufulu faʻamaʻi o le fatu poʻo se tagata e faʻafefe tino. Faʻapitoa laʻasaga o le a manaʻomia e faia i luma o le suʻega pe a fai o iai sau tasi o nei masini.

Aua le ofuina ni kulimi, sunscreen, perfume, poʻo le moisturizer i lou tino i le aso o le suʻega.

O le lagona faʻaosooso e ono lagona e pei o se eletise faʻateʻia. E te ono lagonaina se faʻaletonu e fuafua i le malosi o le lagona. E le tatau ona e lagonaina se tiga pe a maeʻa le suʻega.

E masani lava, ole faʻataʻitaʻiga ole faʻataʻitaʻiga ole neula e mulimuli mai le electromyography (EMG). I le suʻega lea, ua tuu ai le nila i totonu o le maso ma fai atu ia te oe e fai le konakarate i lena maso. O lenei faiga e mafai ona le toʻa i le taimi o le suʻega. E i ai sou tiga maso pe tiga pe a uma le suʻega ile nofoaga na tuu ai le nila.

O lenei suʻega e faʻaaogaina e suʻesuʻe ai neura poʻo faʻaleagaina. O le suʻega ono faʻaaogaina i nisi taimi e iloilo ai faʻamaʻi o neula poʻo maso, e aofia ai:

• Myopathy
• Faʻamaʻi ole Lambert-Eaton
• Myasthenia gravis
• Carpal auala faʻafafa
• Tarsal tunnel syndrome
• Maʻi suka ole suka
• Bell supa
• Guillain-Barré syndrome
• Brlexial plexopathy

NCV e fesoʻotaʻi ma le lautele o le neura ma le tikeri o le myelination (o le i ai o le myelin sheath i luga o le axon) o le neura. O pepe faatoa fananau mai ei ai aoga taua e tusa ma le afa o tagata matutua. O tulaga faʻatauaina mo tagata matutua e masani ona oʻo i le tausaga 3 poʻo le 4.

Faʻaliga: O tulaga masani o tulaga faʻatulagaina e ono eseese teisi i potu eseese o fale suʻesuʻe. Talanoa i lau soifua maloloina e uiga i le uiga o au faʻapitoa suʻega iʻuga.

Tele o taimi, o faʻaletonu iʻuga e mafua mai i neura faʻaleagaina pe faʻatafunaina, aofia ai:

• Axonopathy (faʻaleagaina le umi vaega o le neula sela)
• Poloka poloka (le poloka poloka ua poloka i se mea i tafatafa o le nerve ala)
• Demyelination (faʻaleagaina ma leiloa o le gaʻoa faʻamamaina siomia le neula sela)

O le neura faʻaleagaina pe faʻaleagaina ono mafua mai i le tele o tuutuuga eseʻesega, aofia ai:

• Neura 'ole neivi
• Maʻi suka ole suka
• Aoga afaina o uremia (mai fatugao toilalo)
• Manua manua i se neura
• Guillain-Barré syndrome
• Diphtheria
• Carpal auala faʻafafa
• Brlexial plexopathy
• Charcot-Marie-Tooth faamaʻi (tupuaga)
• Faʻafitauli polyneuropathy faʻafuaseʻi
• Masani peroneal neura faaletonu
• Faʻaletonu media neura le aoga
• Faʻaleagaina neura feusuaʻiga
• Friedreich ataxia
• Paresis aoao
• Mononeuritis multiplex (tele mononeuropathies)
• Amyloidosis Peraimeri
• Radial neura le aoga
• Sciatic neura faaletonu
• Amyloidosis faiga faʻalua
• Sensorimotor polyneuropathy
• Tibial neura le aoga
• Ulnar neura le aoga

Soʻo se neuropathy peripheral mafai mafua ai faʻaletonu iʻuga. Faʻaleagaina o le tuasivi ma disk herniation (herniated nusipepa pulposus) ma neura aʻa taofiofia mafai foi mafua ai faʻaletonu iʻuga.

O se suʻega NCV o loʻo faʻaalia ai le tulaga o alava ninii e sili ona lelei o loʻo totoe. O le mea lea, i nisi tulaga o faʻaiuga atonu e masani, tusa lava pe i ai ni neula faʻaleagaina.
