Mo te putorino waro paipa paipa, he momo poeple e kiia ana ko te paipa MS, ko te tikanga he putorino i hangaia mai i te rino ngawari/te waro waro iti (te waro waro he iti iho i te 0.25%). Ko tenei momo putorino he tino noa, ko te nuinga ka whakamahia i roto i te hanganga hanga, scaffold me etahi atu. He ngawari te ahua o tenei putorino, kaore e kaha ki te kaha me te pehanga, na reira ka taea te whakamahi ki te kawe wai pehanga iti. Na te mea he iti rawa nga taonga miihini o tenei momo maitai, e kore e whakamahia i roto i tewhakamahinga tauari he nui nga whakaritenga, na ka whakahuahia e te tangata te paipa MS, ko te tikanga he paipa paiherea.
Taupānga
Ka whakamahia te nuinga mo nga waahanga kaha me te pehanga, me te mahi whanui mo te mamaoa, te wai, te hau me nga paipa hau.
