The language of touch.

A conceptual framework is discussed from which to consider the meaning of touch in nursing research and practice. The impact of interpersonal touch is examined through a review of literature that demonstrates the relationship of touching to human development. The importance of acknowledging the physiologic foundations of touch is reinforced, with considerations as to dangers in accepting all forms of touch as therapeutic. Existing research into the physiologic and psychosocial bases of tactile interaction is explored, and qualitative symbols for a language of touch are presented. These qualitative symbols create the foundations for discussing a construct of tactile arousal.
