Yila i-Ergonomics yeNtloko yeNtloko, umva, inkxaso ye-Lumbar, iiNqaku eziphambili eziguquguqukayo, ukhululekile kwaye zikhuselekile.
Uyilo lwe-Ergononoric lwesihlalo sokuphatha luyonyusa ukukhuselwa kwamathambo abantu kunye nezihlunu kunye nozinzo kunye nokhuseleko nokhuseleko. Ukukhathazeka ikakhulu kula manqaku alandelayo:
I-1. Intloko: Ukuphakama kunye nokujikeleza kwentloko kunokulungiswa, kuvumela i-vertebracal vertebra yesibeleko yomkhombe, ivumela i-vertebra yesibeleko yomkhombe, ivumela intloko, kwaye ixhathise iofisi. Esona sikhundla silungileyo xa ukuphakama kwentloko ixhasa ngokupheleleyo i-vertebrae yakho.
I-2. Ukubuyela kwesitulo: Eyona ndawo iphambili ye-esinsi esinqeni yi-vertebrae yesithathu neyesine. Isitulo sonke sibuyiselwe ukuphakama, nto leyo inokuhlangabezana ngokulula neemfuno zabasebenzisi abahlukeneyo kwaye zinciphise ubunzima bomzimba womntu othi i-lumbartebrae.
I-3. Inkxaso ye-Lumbar: Inkxaso eyahlukileyo ye-Lumbar ye-Lumba, ukomelela kwinkxaso esebenzayo ye-lumbar, enika umsebenzisi eyona nkxaso isondele kakhulu. Inkxaso ye-lumbar esebenzayo ilungisa i-curvature ukuze wonke umntu ahlaziyeke kancinane ngasemva, avumele i-vertebrae engasemva, evumele i-vertebrae yangasemva ukuze iphumle, ngaloo ndlela ikhulule i-vertebrae yomqolo.
I-4. I-Angle: Uhlengahlengiso lwasimahla, lungafikeleli kwaye luyilolongile uyilo lokuvalela, ukugoba kwangasemva, ukwenziwa kwamandla kunye ne-erastic windows, njl.
