ʻO ka wikiwiki conduction nerve

ʻO ka wikiwiki conduction veveity (NCV) kahi hōʻike e ʻike ai i ka wikiwiki o nā neʻe uila e neʻe ma waena o kahi aʻalolo. Hana ʻia kēia hōʻike me ka electromyography (EMG) e nānā i nā mākala no nā mea kūpono ʻole.

Hoʻokomo ʻia nā pale lina i kapa ʻia nā electrodes o luna ma ka ʻili ma luna o nā ʻalalā ma nā wahi like ʻole. Hāʻawi kēlā me kēia pā i kahi impulse uila māmā. Hoʻoulu kēia i ke aʻalolo.

Hoʻopaʻa ʻia ka hana uila o ke aʻalolo e nā uila uila ʻē aʻe. Hoʻohana ʻia ka mamao ma waena o nā uila a me ka manawa no nā impulses uila ma waena o nā uila i ke ana o ka wikiwiki o nā hōʻailona nerve.

ʻO EMG ka hoʻopaʻa leo ʻana mai nā nila mai i hoʻokomo ʻia i loko o nā mākala. Hana pinepine ʻia kēia i ka manawa like me kēia hoʻāʻo.

Pono ʻoe e noho i kahi mahana maʻamau o ke kino. ʻO ke anuanu a mehana paha e hoʻololi i ka conduction nerve a hiki ke hāʻawi i nā hopena wahaheʻe.

E haʻi i kāu kauka inā loaʻa iā ʻoe kahi defibrillator cardiac a i ʻole pacemaker. Pono e lawe i nā kaʻina kūikawā ma mua o ka hoʻāʻo inā loaʻa iā ʻoe kekahi o kēia mau hāmeʻa.

Mai hoʻokomo i nā lotion, nā pale lā, nā mea ʻala, a me nā mea hoʻoliʻiliʻi ma kou kino i ka lā o ka hoʻāʻo.

E like paha ka impulse me he uila uila lā. ʻIke paha ʻoe i kekahi ʻano ʻino ma muli o ka ikaika o ka impulse. ʻAʻole ʻoe e ʻeha i ka pau ʻana o ka hoʻāʻo.

ʻO ka manawa pinepine, ukali ʻia ka hōʻike conduction nerve e ka electromyography (EMG). I kēia hoʻāʻo, waiho ʻia kahi nila i loko o kahi mākala a haʻi ʻia ʻoe e ʻaelike i kēlā mākala. Hiki i kēia kaʻina hana ke hōʻoluʻolu ʻole i ka wā o ka hoʻāʻo. Loaʻa paha iā ʻoe ka ʻehaʻeha a ʻeha paha ma hope o ka hoʻāʻo ʻana ma ka pūnaewele kahi i hoʻokomo ʻia ai ka nila.

Hoʻohana ʻia kēia hōʻike e hōʻike ai i ka hōʻino a me ka luku ʻana paha o ke aʻalolo. Hoʻohana ʻia ka hōʻike i kekahi manawa e loiloi i nā maʻi o ke aʻalolo a i ʻole nā ​​mākala, me:

• Myopathy
• ʻO Lambert-Eaton maʻi
• Myasthenia gravis
• Carpal tunnel maʻi maʻi
• Tarsal tunnel syndrome
• ʻO ka neuropathy diabetic
• Pāleo Bell
• ʻO Guillain-Barré Syndrome
• Plexopathy Brachial

Pili ʻo NCV i ke anawaena o ke aʻalolo a me ke kekelē o ka myelination (ke kū ʻana o ka uhi myelin ma ke koʻi) o ke aʻalolo. Loaʻa nā waiwai o nā pēpē hānau hou ma kahi o ka hapalua o nā mākua. Hiki ʻia nā waiwai mākua e ka makahiki 3 a i ʻole 4.

Kaha: hiki ke loli iki i nā pae waiwai maʻamau ma waena o nā hale hana ʻokoʻa. E kamaʻilio me kāu mea mālama ola e pili ana i ke ʻano o kāu mau hopena hōʻike kikoʻī.

ʻO ka hapanui pinepine, nā hopena maʻamau ma muli o ka hōʻino a me ka luku ʻana o ke aʻalolo, e like me:

• Axonopathy (hōʻino i ka hapa lōʻihi o ke aʻalolo nerve)
• Palaka hoʻoliʻiliʻi (ke pale ʻia ka manaʻo ma kahi ma ke ala nerve)
• Demyelination (poino a me ka nalo ʻana o ka momona momona e pili ana i ke aʻa nerve)

Ma muli paha o nā ʻano like ʻole nā ​​ʻino ʻino a me ka luku ʻia ʻana, me:

• ʻO ka neuropathy ʻona
• ʻO ka neuropathy diabetic
• Nā hopena o ke aʻa o ka uremia (mai ke kōpaʻa ʻole)
• ʻO ka ʻehaʻeha i kahi aʻalolo
• ʻO Guillain-Barré Syndrome
• Diphtheria
• Carpal tunnel maʻi maʻi
• Plexopathy Brachial
• ʻO ka maʻi Charcot-Marie-Tooth (hoʻoilina)
• ʻO ka polyneuropathy hoʻouluulu maʻi
• ʻO ke kīnā ʻole o ke aʻalolo peroneal
• Distal median nerve disfungsi
• ʻO ke kīnā ʻole nerve wahine
• Friedreich ataxia
• Paresis laulaha
• Mononeuritis multiplex (mau mononeuropathies)
• Amyloidosis kumu
• ʻO ke kīnā ʻole nerve radial
• ʻO ke kīnā ʻole nerve sciatic
• Amyloidosis ʻōnaehana lua
• Sensorimotor polyneuropathy
• ʻO ke kīnā ʻole o Tibial nerve
• ʻO ke kīnā ʻole o ke aʻa Ulnar

Hiki i nā neuropathy āpau ke kumu i nā hopena maikaʻi ʻole. ʻO ka hōʻino i ka iwi kuamoʻo a me ka herniation disk (herniated nucleus pulposus) me ke aʻa aʻa aʻa hiki ke kumu i nā hopena maikaʻi ʻole.

Hōʻike kahi hōʻike NCV i ke kūlana o nā olonā i ʻoi aku ke ola. No laila, i kekahi mau hihia maʻamau paha nā hopena, ʻoiai inā he ʻino nā nerve.
