Ogwiritsa ntchito njinga za olumala nthawi ndi nthawi amatha kudwala zilonda zapakhungu kapena zilonda zomwe zimayamba chifukwa cha kukangana, kupanikizika, ndi kumeta ubweya wa khungu pomwe khungu lawo limalumikizana nthawi zonse ndi zinthu zopangidwa panjinga yawo.Zilonda zopatsirana zimatha kukhala vuto lalikulu, lomwe nthawi zonse limatha kudwala matenda oopsa kapena kuwonongeka kwapakhungu.Kafukufuku watsopano mu International Journal of Biomedical Engineering and Technology, akuyang'ana momwe njira yogawa katundu ingagwiritsire ntchito sinthani zikukukwa ogwiritsa ntchito kupewa zilonda zoterezi.

Sivasankar Arumugam, Rajesh Ranganathan, ndi T. Ravi a Coimbatore Institute of Technology ku India, akunena kuti aliyense wogwiritsa ntchito njinga ya olumala ndi yosiyana, maonekedwe a thupi, kulemera kwake, kaimidwe, ndi kuyenda kosiyana kwa nkhani.Chifukwa chake, yankho limodzi ku vuto la zilonda zam'mimba silingatheke ngati onse oyenda panjinga athandizidwe.Maphunziro awo ndi gulu la ogwiritsa ntchito odzipereka amawulula, kutengera miyeso ya kukakamizidwa, kuti kusintha kwa munthu payekha kumafunika kuti aliyense wogwiritsa ntchito achepetse kumeta ubweya ndi mphamvu zotsutsana zomwe zimayambitsa zilonda zam'mimba.

Odwala oyenda olumala omwe amathera nthawi yayitali atakhala, chifukwa cha matenda osiyanasiyana monga kuvulala kwa msana (SCI), paraplegia, tetraplegia, ndi quadriplegia ali pachiopsezo cha zilonda zopanikizika.Akakhala pansi, pafupifupi magawo atatu mwa anayi a kulemera kwa thupi lonse la munthu amagawidwa m'matako ndi kumbuyo kwa ntchafu.Nthawi zambiri anthu oyenda panjinga ya olumala achepetsa minyewa m'mbali imeneyi ya thupi kotero kuti sangathe kulimbana ndi kupindika komwe kumapangitsa kuti minyewayi iwonongeke yomwe imayambitsa zilonda.Ma cushion amtundu wanji wapanjinga chifukwa cha matenda awo omwe ali pashelefu sapereka makonda kuti agwirizane ndi munthu wina wapanjinga ya olumala motero amangoteteza pang'ono kukula kwa zilonda zopanikizika.

Zilonda zapaintaneti ndizovuta zachitatu zathanzi zotsika mtengo kwambiri pambuyo pa khansa ndi matenda amtima, kotero pakufunika kupeza njira zothetsera mavuto osati kungopindulitsa ogwiritsa ntchito akumagudumu okha, mwachiwonekere, koma kuti achepetse ndalama kwa ogwiritsa ntchitowo komanso machitidwe azaumoyo omwe amadalira.Gululi likugogomezera kuti njira yasayansi yosinthira ma cushion ndi zigawo zina zomwe zingathandize kuchepetsa kuwonongeka kwa minofu ndi zilonda ndizofunikira mwachangu.Ntchito yawo imapereka chidule cha zovuta zomwe zimakhalapo kwa ogwiritsa ntchito njinga za olumala pankhani ya zilonda zopanikizika.Njira yasayansi, akuyembekeza, ipangitsa kuti pakhale njira yabwino yosinthira ma cushion akunjinga ndi zotchingira zoyenera munthu aliyense woyenda panjinga.
