No one can predict how long someone will be in a coma. It is important for him to have range of motion to both arms and legs daily. Also we usually recommend high top sneakers in bed to help prevent foot drop. You should talk to him alot and play music because it is thought that sometimes people in comas can hear. Make sure he is turned every 2 hours to prevent bed sores. Good luck and pray. You have a hard time ahead of you. Jan
