ʻO kahi ana hoʻohālikelike ma ka neurology, ka electromyogram (EMG) e hiki ai ke kālailai i ka hana uila o nā ʻalolo a me nā mākala. Ma waho aʻe o ka hoʻokolohua hoʻokolohua, kōkua ia i ke kuhi ʻana i nā ʻano maʻi like ʻole a me nā muscular.

ʻO ka electromyogram, i kapa ʻia hoʻi ʻo electroneuromyogram, electronography, ENMG a i ʻole EMG, ke manaʻo e kālailai i nā impulses nerve i nā aʻalolo kaʻa, nā aʻalolo sensory a me nāʻiʻo. Nīnau nui i ka neurology, ʻae ia e loiloi i ka hana o nā aʻa a me nā mākala.

I ka hoʻomaʻamaʻa ʻana, pili ka hoʻokolokolo ʻana i ka hoʻopaʻa ʻana i ka hana uila o nā aʻalolo a me ka hōʻemi ʻana o kahi mākala ma ke kau ʻana i kahi nila ma ka ʻiʻo a i ʻole ka ʻaoʻao o ke aʻalolo, a i ʻole ke kau ʻana i kahi uila i ka ʻili inā ʻo ke aʻalolo a i ʻole ka mākala ma luna wale nō. Nānā ʻia ka hana uila i ka hoʻomaha, ma hope o ka hoʻoulu uila uila a i ʻole i ka hana manawaleʻa contraction o ka mea maʻi.

Lawe ʻia ka hoʻokolokolo ma ka haukapila, ma ka hale hana no ka mākaʻikaʻi hana o ka ʻōnaehana hopohopo, a i ʻole ke keʻena o ka neurologist inā lako pono ia. ʻAʻole pono kahi hoʻomākaukau. ʻO ka ninaninau ʻana, me ka ʻole o ka makaʻu, he 45 a 90 paha mau minuke ke kaukaʻi ʻia.

Kapa ʻia ka hāmeʻa no ka hana EMG i kahi electromyograph. Ke hoʻohana nei i nā electrodes (nā pā liʻiliʻi) i kau ʻia ma ka ʻili, hoʻonāukiuki ia i nā aʻa uila i ka uila ma ka hoʻouna ʻana i kahi pōkole loa (mai ka ʻumi a kahi millisecond) a me ka ikaika haʻahaʻa (he mau kaukani o kahi ampere) uila uila. ). Hoʻolahalaha ʻia kēia ʻāʻī nerve i ka mākala, a laila e ʻaelike a neʻe. Hoʻopili ʻia nā mea hoʻopili i ka ʻili i hiki ke hoʻopaʻa i ka hana uila o ke aʻalolo a me / a i ʻole nāʻiʻo. A laila kope ʻia kēia ma ka hāmeʻa a kālailai ʻia ma ka pakuhi i ke ʻano o nā kipi.

Kaukaʻi ʻia i nā ʻōuli a me nā pathology i ʻimi ʻia, hiki ke hoʻohana i nā ʻano hoʻokolohua like ʻole:

• ka electromyogram maoli o ka hoʻopaʻa ʻana i ka hana uila o ka mākala ma ka maha a ke hāʻawi manawaleʻa ka mea maʻi iā ia. Hiki ke hoʻopaʻa i ka hana o kekahi mau olonā wale. No kēia, hoʻolauna ke kauka i kahi nila kuʻi maikaʻi, me kahi mea ʻike, i loko o ka mākala. ʻO ke kālailai ʻana i ka hana uila o ka mākala e hiki ai ke ʻike i ka nalo ʻana o nā olonā aʻa a i ʻole ka pono ʻole o ka mākala;
• ke aʻo ʻana i nā wikiwiki conduction o nā motika motika i ka hoʻonāukiuki ʻana i ke aʻalolo ma nā helu ʻelua i mea e kālailai ai i ka wikiwiki a me nā mana conduction o nā pulupulu nerve ma kekahi lima, a me ka pane muscular ma kekahi lima;
• ke aʻo ʻana i nā wikiwiki conduction sensory hiki ke hiki ke ana i ka lawe ʻana o nā olonā o ke aʻalolo i ka iwi kuamoʻo;
• hoʻohana ʻia nā hoʻāʻo hoʻonāukiuki hou e hoʻāʻo i ka hilinaʻi o ka lawe ma waena o ke aʻalolo a me ka mākala. Hoʻoulu pinepine ʻia ke aʻalolo a kālailai ʻia ka pane o nā mākala. I ke kikoʻī, nānā ʻia ʻaʻole hoʻemi ʻia kāna amplitude i kēlā me kēia maʻamau.

Hiki i ka hoʻoulu uila i mea ʻoluʻolu ʻole ma mua o ka ʻeha. Hiki i nā nila kele ke hana i ka ʻeha liʻiliʻi loa.

Hiki ke kuhikuhi ʻia ka electromyogram i ke alo o nā ʻōuli ʻokoʻa.

• ma hope o kahi ulia pōpilikia i hopena i ka hōʻino ʻia o nā aʻalolo;
• ʻeha ʻeha (myalgia);
• nāwaliwali o ka mākala, ka nalowale ʻana o ke kani o ka mākala;
• ʻū mau, numbness, tingling (paramnesia);
• paʻakikī i ka mimi ʻana a i ʻole ka paʻa ʻana i ka mimi, ka hele ʻana a i ʻole ka paʻa ʻana o ka noho
• ka hana erectile i nā kāne;
• ʻeha perineal i hōʻike ʻole ʻia i nā wahine.

Kaukaʻi ʻia i nā hopena, hiki i ke hoʻokolokolo ke ʻike pono i nā maʻi like ʻole a i ʻole nā ​​leona.

• maʻi maʻi (myopathy);
• haki nāʻiʻo (ma hope o ke kahakaha ʻana, ka ʻeha a hānau hānau paha i ka perineum, no ka laʻana);
• carpal tunnel syndrome;
• i ka hanana o ka hōʻeha i ke aʻa aʻa ma hope o kahi trauma, ke aʻo ʻana i nā wikiwiki conduction hiki ke wehewehe i ke kiʻekiʻe o ka hōʻino ʻana i ke ʻano nerve i hoʻopili ʻia (root, plexus, nerve i kāna mau ʻāpana like ʻole ma ka lālā) a me kāna kekelē o hoʻohaʻahaʻa;
• maʻi o ke aʻalolo (neuropathy). Ma ke kālailai ʻana i nā wahi like ʻole o ke kino, hiki i ka EMG ke ʻike inā he laha a maʻi paha ka maʻi o nā aʻa a no laila e hoʻokaʻawale ai i nā polyneuropathies, nā mononeuropathies he nui, nā polyradiculoneuropathies. Kaukaʻi ʻia i nā mea pono ʻole i ʻike ʻia, hiki nō hoʻi ke kuhikuhi pololei i ke kumu o ka neuropathy (genetics, maʻi pale, mea ʻona, diabetes, maʻi ʻaʻai, a pēlā aku.);
• ka maʻi o nā mākala neʻe moto i ka iwi kuamoʻo (motor neuron);
• myasthenia gravis (kahi maʻi autoimmune laha ʻole o ka hui neuromuscular).
