Chiyero chekuenzanisa mutsinga, iyo electromyogram (EMG) inoita kuti zvikwanise kuongorora kushanda kwemagetsi kwetsinga uye tsandanyama. Mukuwedzera kune kuongororwa kwekliniki, inobatsira mukuongororwa kwezvakasiyana-siyana zvekutya uye muscular pathologies.

Iyo electromyogram, inonziwo electroneuromyogram, electronography, ENMG kana EMG, ine chinangwa chekuongorora tsinga dzetsinga mumotokari tsinga, tsinga dzekunzwa uye tsandanyama. Kuongorora kwakakosha muneurology, inobvumira kuongorora kushanda kwetsinga uye tsandanyama.

Mukuita, kuongororwa kunosanganisira kurekodha kushanda kwemagetsi etsinga pamwe nekupwanya kwemhasuru kungave nekunamira tsono mumhasuru kana padivi petsinga, kana nekunamira electrode paganda kana tsinga kana tsandanyama. zviri pamusoro. Chiitiko chemagetsi chinoongororwa pakuzorora, mushure mekugadzirwa kwemagetsi ekugadzira kana nekuzvidira chibvumirano chekuedza kwemurwere.

Kuongororwa kunoitwa muchipatara, murabhoritari yekuongorora kunoshanda kwehurongwa hwemitsipa, kana muhofisi yeneurologist kana yakashongedzerwa. Hapana kugadzirira kunodiwa. Kuongororwa, pasina njodzi, kunotora 45 kumaminitsi e90 zvichienderana neprotocol inoshandiswa.

Muchina wekuita EMG unonzi electromyograph. Ichishandisa maelectrodes (madiki madiki) akaiswa paganda, inomutsa tsinga dzetsinga nemagetsi nekutumira pfupi pfupi (kubva pagumi kusvika pamillisecond) uye yakaderera intensity (zvishoma zvishoma zvezviuru zveampere) mashura emagetsi. ) Iyi tsinga yetsinga inoparidzirwa kune tsandanyama, iyo inobva yabvumirana uye inofamba. Sensors yakanamatira paganda inoita kuti ikwanise kurekodha kushanda kwemagetsi kwetsinga uye / kana tsandanyama. Izvi zvinobva zvanyorwa pamudziyo uye kuongororwa pachiratidziro nenzira yezvirongwa.

Zvichienderana nezviratidzo uye pathology inotsvakwa, mhando dzakasiyana dzebvunzo dzinogona kushandiswa:

• iyo chaiyo electromyogram inosanganisira kudzidza kushanda kwemagetsi kwemhasuru pakuzorora uye kana murwere achizvidira chibvumirano. Zvinokwanisika kudzidza basa rezvishoma tsandanyama fibers. Nokuda kweizvi, chiremba anotanga tsono yakanaka, ine sensor, mukati memhasuru. Kuongororwa kwebasa remagetsi emusumbu kunoita kuti zvikwanise kuona kurasikirwa kwemagetsi emagetsi emagetsi kana kusakanganiswa kwemhasuru;
• chidzidzo chekufambisa kwekufambisa kwemafibers emotokari kunosanganisira kukurudzira tsinga panzvimbo mbiri kuitira kuti uongorore kukurumidza uye kukwanisa kwekuita kwehutano hwemagetsi kune rumwe rutivi, uye muscular response kune rumwe rutivi;
• chidzidzo chekunzwa kwekufambisa kukurumidza kunoita kuti zvikwanise kuyera kufambisa kwemafivha ekunzwa kwetsinga kumusana wepelinha;
• kudzokorora stimulation bvunzo dzinoshandiswa kuyedza kuvimbika kwekutapurirana pakati petsinga uye tsandanyama. Iyo tsinga inodzokororwa inokurudzirwa uye mhinduro yemhasuru inoongororwa. Kunyanya, inotariswa kuti amplitude yayo haina kuderera zvisina kujairika nekukurudzira kwega kwega.

Kukurudzira kwemagetsi kunogona kunge kusingafadzi pane kurwadza. Tsono dzakanaka dzinogona kukonzera kurwadziwa kushoma.

Iyo electromyogram inogona kurongerwa mukutarisana nezviratidzo zvakasiyana:

• mushure metsaona iyo ingave yakakonzera kukuvara kwetsinga;
• kurwadziwa kwemhasuru (myalgia);
• kushaya simba kwemhasuru, kurasikirwa kwemasumbu;
• kuramba kugwinha, chiveve, kurira (paramnesia);
• kunetseka kuita weti kana kubata weti, kupasa kana kubata tsvina
• erectile dysfunction muvarume;
• marwadzo asina kutsanangurwa perineal muvakadzi.

Zvichienderana nemhedzisiro, kuongororwa kunogona kuongorora zvirwere zvakasiyana kana maronda:

• chirwere chetsandanyama (myopathy);
• kuputika kwemisumbu (mushure mekuvhiyiwa, kukuvadzwa kana kuberekwa mu perineum, somuenzaniso);
• carpal tunnel syndrome;
• kana pakaitika kukuvara kumudzi wetsinga zvichitevera kukuvadzwa, kudzidza kwekumhanyisa kumhanya kunoita kuti zvikwanise kudoma nhanho yekukuvadzwa kune yakakanganisika tsinga chimiro (mudzi, plexus, tsinga muzvikamu zvayo zvakasiyana padivi pegumbo) uye dhigirii re impairment;
• chirwere chetsinga (neuropathy). Nokuongorora nzvimbo dzakasiyana dzemuviri, EMG inoita kuti zvikwanise kuona kana chirwere chetsinga chiri kupararira kana kuti chinowanikwa munzvimbo uye nokudaro kusiyanisa polyneuropathies, mononeuropathies yakawanda, polyradiculoneuropathies. Zvichienderana nekukanganisa kwakaonekwa, zvinoitawo kuti zvikwanise kunanga kune chikonzero cheuropathy (genetics, immune immune disorder, toxicant, chirwere cheshuga, hutachiona, nezvimwewo);
• chirwere chemotor nerve cells mumusana (motor neuron);
• myasthenia gravis (chirwere chisingawanzoitiki chemuviri weuromuscular junction).
