Indima yesali kukubonelela ngenkxaso esebenzayo kwizinqe ngexesha lokukhwela. Siyazi ukuba kwinkqubo yokukhwela, imilenze, izinqe kunye neengalo nganye ithwala i-1/3 yobunzima bomzimba (qaphela: ungakhathazeki ngenani 1/3, iimodeli ezahlukeneyo, iimeko zokukhwela, njl.njl., umlinganiselo awufani), Isali enobunzima obuphakathi kwaye ehambelana negophe lesinqe inokuthwala ubunzima ekufanele ibuthwale.

Xa ukhetha isihlalo, kukho izinto ezimbalwa ekufuneka uzikhumbule:

(1) Khetha isihlalo ngokwebubanzi be-ischium

Okukhona amathambo okuhlala ebanzi, kokukhona umqamelo ubanzi. Abafazi bafuna iisali ezibanzi kunamadoda. I-engile engezantsi ye-pelvis yi-70° ukuya kwi-75° kumadoda kunye ne-90° ukuya kwi-100° kubafazi.

2) Isihlalo asithambile kangangoko

Into eyenza abakhweli beebhayisekile abaninzi babe buhlungu yi-"PP pain" (iintlungu zesinqe), kwaye ukuze ukhululeke, faka umqamelo obanzi nothambileyo wesihlalo. Njengoko kukhankanyiwe ngasentla, iimpundu zithwala i-1/3 yobunzima ngexesha lokukhwela, isihlalo sithambile kakhulu ukuba singanika inkxaso esebenzayo, i-perineum iyacinezelwa, kwaye ukubila kuyacotha.

Olu hlobo lovakalelo lufana nokuhlala kwiibhentshi eziqinileyo kunye neesofa ezithambileyo ezingangeni moya ixesha elide ehlotyeni. Emva kokuhlala kwibhentshi eqinileyo ixesha elide, uya kuziva iintlungu ezimpundu, kodwa ukuba uhlala kwisofa ethambileyo kakhulu kwaye ingangeni moya ixesha elide, ngaba ayikhululeki ngakumbi?
