Grandmaster JinBodhi: Yes, they can. They can use a walking stick or have someone help them while circling. After a period, they will have to practice independently while being watched by others. If they can circle on their own, then they should not need further help in the future. I have seen someone in Malaysia practicing in a wheelchair; he was controlling the wheel with one hand and doing the dragon palm with the other hand. I heard that he is able to move without the wheelchair now. So, if you are facing serious mobility issues, try Energy Bagua. It will help your condition if you are willing to put effort into it.
