As the other commenter mentions, tactile signing is the most common. There can be differences between that and the normal sign language used in the country. When I've communicated with deafblind individuals using tactile signing, I have normally just used the normal sign language for Ireland (Irish Sign Language) while they held my hands. It's a highly personal (and can be emotional) form of communication.
