Positioning the body with the torso leaning toward the person being addressed, the arms at one's sides, and the chest, abdomen, and lower extremities easily seen. This form of body positioning during communication implies that one is actively listening and emotionally available to the client or patient. By contrast, a closed posture (in which one leans back, crosses one's arms on the chest and crosses the legs) implies that a person is less receptive to the other person.
