Dystonia is a neurological movement disorder that makes it difficult for people to control their muscles. The Dystonia Interest Group (DIG) supports people and their families living with this disorder.

Their new identity for DIG is acronym based with the letters forming the shape of a figure. The mark plays with positive and negative showing an invisible "I" centred to form the body of the figure. The letters are made up of blue and green graphic elements that represent the entities which come together as one to support the individual.
