my ex-T demonstrated this exercise with me mainly so i could use it at home with my husband when i was triggered. it can help with grounding but also assists the the person who is triggered to be able to 'communicate' with out words (by how forceful they pull back on the scarf or rope) how much dysregulation they are experiencing in that moment. this is helpful to those who are incapable or struggle with being able to use cognitive language in a triggered moment of flight or flight to covey their emotional state.

funny enough, this is probably one of the more helpful skills that my ex-T actually taught me in therapy.
