Her mobility is nowhere near as bad as her LARP would suggest, but even if she was 100% healthy prior to grifting the power chair, she definitely can't just climb out of it now and go back to acting like a normal person again. Anyone who's had to wear one of those moonboots for a broken foot can tell you how rapidly the supporting muscles and tendons atrophy, and even something as minor as four weeks in it will require a reasonably disciplined round of rehab. I have no idea what the rehab of getting out of a power chair would look like, but given she couldn't do the rehab to strengthen her sore hip to avoid going into it in the first place, it's safe to say Vicky is fucked.
She pretended to be a sped for pity points on tumblr, only the political winds changed and now she's stuck that way.
