Looking for opinions

Hi I’ve posted in this group before as bibistevens-190317 a month ago and explained my partners situation, accident and progress, he was only three weeks in at that point but now I have some questions and I’m not getting help from doctors with it as visiting hours don’t start the same time drs do their rounds here, so I was wondering if anyone has experienced toe flickers? Do toes spasm? Google isn’t telling me anything at all, his apparently complete Asia A but he can feel hot blankets on him and cold drinks on his thigh, his being trying to move his big toes and they flicker up amd down and sometimes do it at random does anyone have any experience with this? If so what does it mean? Is it a good sign? TIA
