if you are making an afo for someone with cerebal palsey and you could only use these materials, cardboard, rubber bands, duck tape, masking tape, elastic, string, bubble wrap, yarn, foam, felt, velcro tape, and hot glue or craft glue. how would you make a afo? what materials would you use? why would you use those materials?
oh by the way it has to be able to be ajustable and come off easily, the person wouldn't be able to bend their foot downwards but they can bend it upwards, and it has to be comfortable so they can wear it 24 7.
good luck designing!
