Electromyography

Electromyography (EMG) bvunzo inoongorora hutano hwemhasuru uye tsinga dzinodzora mhasuru.

Mutapi wezvehutano anopinza nhete yakaipisisa tsono electrode kuburikidza neganda kupinda musumbu. Iyo electrode pane tsono inotora chiitiko chemagetsi chakapihwa nemhasuru dzako. Ichi chiitiko chinoonekwa pane iripedyo yekutarisa uye inogona kunzwika kuburikidza nemutauri.

Mushure mekuiswa kwema electrode, unogona kubvunzwa kuti utore musuru. Semuenzaniso, nekukotamisa ruoko rwako. Basa remagetsi rinoonekwa pane yekutarisa rinopa ruzivo nezve yako mhasuru kugona kupindura kana tsinga kumhasuru dzako dzasimudzirwa.

Tsinga yekuitisa velocity bvunzo inowanzoitwa panguva imwe chete yekushanya seEMG. Iko velocity bvunzo inoitwa kuti uone kukurumidza kuti zviratidzo zvemagetsi zvinofamba sei kuburikidza nehutano.

Hapana gadziriro yakakosha inowanzo kuve inodikanwa. Dzivisa kushandisa chero mafuta kana mafuta pazuva rekuyedza.

Tembiricha yemuviri inogona kukanganisa mhedzisiro yeiyi bvunzo. Kana kuchitonhora zvakanyanya kunze, unogona kutaurwa kuti umirire mune inodziya mukamuri kwechinguva bvunzo isati yaitwa.

Kana iwe uri kutora inotapisa ropa kana anticoagulants, zivisa mupi ari kuita bvunzo isati yaitwa

Iwe unogona kunzwa kumwe kurwadziwa kana kusagadzikana kana tsono dzikaiswa. Asi vanhu vazhinji vanokwanisa kupedzisa bvunzo pasina matambudziko.

Mushure mezvo, mhasuru inogona kunzwa yakapfava kana kupwanya kwemazuva mashoma.

EMG inowanzo shandiswa kana munhu aine zviratidzo zvekushaya simba, kurwadziwa, kana kusanzwisisika kwekunzwa.Inogona kubatsira kuudza musiyano uripo pakati pemhasuru kushaya simba kunokonzerwa nekukuvara kwetsinga yakanamatira kune mhasuru, uye kushaya simba nekuda kwekushushikana kwesystem system, senge hosha dzemhasuru.

Iko kunowanzo kuve kushomeka kushoma kwemagetsi kuita mune mhasuru panguva yekuzorora. Kuisa tsono kunogona kukonzera kumwe kuita kwemagetsi, asi kana mhasuru dzikanyarara pasi, panofanirwa kunge paine chiitiko chidiki chemagetsi chinoonekwa.

Paunoshandura mhasuru, chiitiko chinotanga kuoneka. Sezvaunobata mhasuru yako zvakanyanya, chiitiko chemagetsi chinowedzera uye pateni inogona kuonekwa. Iyi pateni inobatsira chiremba wako kuona kana mhasuru iri kupindura sezvainofanirwa.

EMG inogona kuona matambudziko nemhasuru dzako panguva yekuzorora kana chiitiko. Kukanganiswa kana mamiriro ezvinhu anokonzeresa mhedzisiro anosanganisira anotevera:

• Doro neuropathy (kukuvara kwemitsipa kubva kunwa doro rakawandisa)
• Amyotrophic lateral sclerosis (ALS; hosha yemasero etsinga muuropi uye musana wesipinha inodzora kufamba kwemhasuru)
• Axillary nerve kusagadzikana (kukuvara kweiyo nerve inodzora kufamba kwepafudzi uye kunzwa)
• Becker tsandanyama dystrophy (tsandanyama kushaya simba kwemakumbo uye chiuno)
• Brachial plexopathy (dambudziko rinokanganisa seti yetsinga dzinosiya mutsipa dzichipinda ruoko)
• Carpal tunnel syndrome (dambudziko rinokanganisa mitezo yepakati muchanza neruoko)
• Cubital tunnel syndrome (dambudziko rinobata iyo ulnar nerve mugokora)
• Cervical spondylosis (kurwadziwa kwemutsipa kubva pakupfeka pamadhisiki nemapfupa emutsipa)
• Kazhinji peroneal nerve kusagadzikana (kukuvara kweiyo yegaoneone inotungamira pakurasikirwa kwekufamba kana kunzwa mutsoka uye gumbo)
• Denervation (yakaderedzwa tsinga inosimudzira yemhasuru)
• Dermatomyositis (hosha yemhasuru inosanganisira kuzvimba uye kuputika kweganda)
• Akasiyana epakati etsinga kusagadzikana (dambudziko rinokanganisa median nerve mune ruoko)
• Duchenne muscular dystrophy (chirwere chakagara nhaka chinosanganisira kushaya simba kwemhasuru)
• Facioscapulohumeral muscular dystrophy (Landouzy-Dejerine; hosha yemhasuru kushaya simba uye kurasikirwa kwemhasuru nyama)
• Kuzivikanwa kweapo neapo kushaya mitezo (kusagadzikana kunokonzeresa kushomeka kwemhasuru uye dzimwe nguva kwakadzika kupfuura zvakajairika muyero we potassium muropa
• Hwevakadzi tsinga kusagadzikana (kurasikirwa kwekufamba kana kunzwa mune zvimwe zvikamu zvemakumbo nekuda kwekukuvara kwehunhu hwechikadzi)
• Friedreich ataxia (chirwere chakagarwa nhaka chinokanganisa nzvimbo dziri muuropi nemuzongoza izvo zvinodzora kubatana, kufamba kwemhasuru, uye mamwe mabasa)
• Guillain-Barré syndrome (autoimmune kusagadzikana kwemitsipa inotungamira kukundikana kwemhasuru kana kuora mitezo)
• Lambert-Eaton syndrome (autoimmune kusagadzikana kwemitsipa inokonzeresa kushomeka kwemhasuru)
• Multiple mononeuropathy (huta hwehurongwa hwehurwere hunosanganisira kukuvara kune angangoita maviri akapatsanurwa maseru nzvimbo)
• Mononeuropathy (kukuvara kune imwe tsinga inokonzeresa mukurasika kwekufamba, kunzwa, kana rimwe basa retsinga iyoyo)
• Myopathy (kushomeka kwemhasuru kunokonzerwa nematambudziko akati wandei, kusanganisira muscular dystrophy)
• Myasthenia gravis (autoimmune kusagadzikana kwemitsipa inokonzeresa kushomeka kwemhasuru dzekuzvidira)
• Peripheral neuropathy (kukuvara kwemitsipa kure nehuropi uye musana)
• Polymyositis (kushaya simba kwemhasuru, kuzvimba, unyoro, uye kukuvara kwemasuru emhasuru yemhasuru)
• Radial nerve dysfunction (kukuvara kweiyo radial nerve inokonzeresa kurasikirwa kwekufamba kana kwekunzwa kumashure kweruoko kana ruoko)
• Sciatic nerve dysfunction (kukuvara kana kumanikidza kune iyo sciatic nerve inokonzeresa kushaya simba, chiveve, kana kugwinha gumbo)
• Sensorimotor polyneuropathy (mamiriro anokonzeresa kudzikira kwekufamba kana kunzwa nekuda kwekukuvara kwetsinga)
• Shy-Drager syndrome (nervous system chirwere chinokonzera zviratidzo zvemuviri)
• Thyrotoxic periodic kuoma mitezo (kushaya simba kwemhasuru kubva pamwero wakakwira wehormone yehroid
• Tibial nerve kusagadzikana (kukuvara kwetibial nerve inokonzeresa kurasikirwa kwekufamba kana kunzwa mutsoka)

Ngozi dzemuedzo uyu dzinosanganisira:

• Kubuda ropa (kushoma)
• Utachiona panzvimbo dzemagetsi (zvisingawanzoitika)
