Support means you get items to help you and people to support you by assisting you with the things you can't do (on your own). This works for social and routine stuff just as much as for sensory things.
If I need someone to do the shopping for me, that's true wether I can't shop due to social stuff or due to sensory stuff. Wether I need an expensive communication tablet due to language stuff or expensive ANC headphones due to sensory stuff, I still need it.
