Look at what you said about your mother's recovery. For her safety, she is not allowed to go out and rest at home. But you are wrong. You'd better not let her do anything, because the disease needs proper activities and further recovery. Isn't she still able to walk around? Then you can learn from Tai Ji Chuan or take a walk. Don't let her do anything else. At the same time, I wish your mother a speedy recovery!
