What is best way to help someone frail down a few steps?

Caution. Walk beside and slightly ahead of them and let them hold on to you! be prepared to catch them if a stumble or slip. They can balance and hold on better that you can hold on to them and balance them and you will not hurt them if they are holding on to you. See assistance from a physical therapist or occupational therapist if necessary. Make sure you are able to handle them and not injure you!
