Uvavanyo lweBERA: yintoni, yenzelwe ntoni kwaye yenziwa njani

Umxholo

• Loluphi uvavanyo
• Luqhutywa njani uviwo

Uvavanyo lwe-BERA, ekwabizwa ngokuba yi-BAEP okanye iBrainstem Auditory evoked Potential, luvavanyo oluvavanya yonke inkqubo yokuvavanywa, ukujonga ubukho bokulahleka kwendlebe, okunokwenzeka ngenxa yokwenzakala kwi-cochlea, luvo lokuva okanye ubuchwephesha bengqondo.

Nangona inokwenziwa kubantu abadala, uvavanyo lweBERA lwenziwa rhoqo kubantwana nakwiintsana, ngakumbi xa kukho umngcipheko wokulahleka kokuva ngenxa yeemeko zofuzo okanye xa kukho iziphumo eziguqulweyo kuvavanyo lwendlebe, olo luvavanyo olwenziwe kwakamsinya emva kokuzalwa kwaye kuvavanya amandla okuva kosana. Qonda ukuba uvavanyo lwendlebe lwenziwa njani kunye neziphumo.

Ukongeza, olu vavanyo lunokuyalelwa nakubantwana abalibazise ukukhula kolwimi, njengoko oku kulibaziseka kunokuba luphawu lweengxaki zokuva. Funda indlela yokuchonga ukuba umntwana wakho akamameli kakuhle.

Loluphi uvavanyo

Uvavanyo lweBERA luboniswa ikakhulu kuvavanyo lokukhula kunye nempendulo yabantwana, iintsana ezisandula ukuzalwa, abantwana abane-autistic okanye abo baneenguqu kwimfuza, njengeDown's Syndrome.

Ukongeza, uvavanyo lunokwenziwa ukufumanisa ukulahleka kwendlebe kubantu abadala, ukuphanda unobangela we-tinnitus, ukubona ubukho bamathumba abandakanya imithambo-luvo yokuvavanya okanye ukujonga abaguli esibhedlele okanye abagulayo.

Luqhutywa njani uviwo

Uviwo luhlala phakathi kwemizuzu engama-30 ukuya kwengama-40 kwaye luhlala lusenziwa ngelixa ulele, kuba luvavanyo olunobuzaza kakhulu kwaye, ke ngoko, nayiphi na intshukumo inokuphazamisa iziphumo zoviwo. Ukuba umntwana ushukuma kakhulu ngexesha lokulala, ugqirha unokucebisa ngokumthambisa umntwana ngalo lonke ixesha loviwo, ukuqinisekisa ukuba akukho ntshukumo kwaye nesiphumo asitshintshi.

Uviwo luqukethe ukubeka i-electrode emva kwendlebe nasebunzini, ukongeza kwi-headset enoxanduva lokuvelisa izandi eziza kwenza ukuba i-brainstem isebenze kunye ne-nerves ye-auditory, ivelise i-spikes kumbane ngokobungakanani besishukumisi, esibanjiweyo yi-electrode yaza yatolikwa ngugqirha ukusuka kumaza esandi arekhodwe sisixhobo.

Uvavanyo lweBERA alufuneki naluphi na ulungiselelo olukhethekileyo kwaye luyinkqubo engafunekiyo engabangeli naziphi na iintlungu okanye ukungonwabi.
