Electromyography (EMG)

ʻO ka electromyography (EMG) kahi kaʻina hana hoʻomaopopo e loiloi i ke olakino o nā ʻiʻo a me nā pūnaewele nerve e kaohi ana iā lākou (nā neuron motor). Hiki i nā hopena EMG ke hōʻike i ka hana ʻole o ka nerve, ka hana ʻole o ka ʻiʻo a i ʻole nā ​​pilikia me ka hoʻoili ʻana o ka hōʻailona nerve-to-muscle. Hoʻouna nā neuron motor i nā hōʻailona uila e hoʻoulu ai i nā ʻiʻo e hoʻopaʻa. Hoʻohana ka EMG i nā mea liʻiliʻi i kapa ʻia ʻo electrodes e unuhi i kēia mau hōʻailona i nā kiʻi, nā leo a i ʻole nā ​​waiwai helu e wehewehe ʻia e kahi loea.

Hiki i kāu kauka ke kauoha i kahi EMG inā loaʻa iā ʻoe nā hōʻailona a i ʻole nā ​​hōʻailona e hōʻike ana i kahi maʻi o ka ʻiʻo a i ʻole nā ​​manaʻo. ʻO kēlā mau hōʻailona paha: Ke ʻōhule ʻana Ke ʻano ʻole ʻana Ka nāwaliwali o nā ʻiʻo ʻEha o nā ʻiʻo a i ʻole ka ʻeha ʻO kekahi mau ʻano o ka ʻeha o nā lālā Hoʻohana pinepine ʻia nā hopena EMG e kōkua i ka ʻike a i ʻole ke kāpae ʻana i ka nui o nā kūlana e like me: Nā maʻi o nā ʻiʻo, e like me ka muscular dystrophy a i ʻole polymyositis Nā maʻi e pili ana i ka pilina ma waena o ka nerve a me ka ʻiʻo, e like me ka myasthenia gravis Nā maʻi o nā nerves ma waho o ka spinal cord (peripheral nerves), e like me ka carpal tunnel syndrome a i ʻole peripheral neuropathies Nā maʻi e pili ana i nā motor neurons i loko o ka lolo a i ʻole ka spinal cord, e like me ka amyotrophic lateral sclerosis a i ʻole polio Nā maʻi e pili ana i ke aʻa nerve, e like me ka herniated disk i loko o ke kua

He hana maʻamau me ka liʻiliʻi o ka pilikia ka EMG, a he kakaʻikahi nā pilikia. Aia kahi pilikia iki o ke kahe koko, ka maʻi, a me ka hōʻino ʻana i nā aʻalolo ma kahi i hoʻokomo ʻia ai ka nila electrode. I ka wā e nānā ʻia ai nā ʻiʻo ma ka paia umauma me ka nila electrode, aia kahi pilikia iki loa e hiki ai ke hoʻokuʻu i ka ea i loko o ka wahi ma waena o nā māmā a me ka paia umauma, e hoʻopōʻino ai i ka māmā (pneumothorax).
